Higher price of electric cars a concern for more than half of UK consumers

IEA Electricity Market Outlook 2023-2025 projects faster demand growth as renewables and nuclear dominate supply, stabilizing power-sector carbon emissions, with Asia leading expansion despite energy crisis shocks and weather-driven volatility.

Key Points

IEA forecast for 2023-2025 electricity demand: renewables and nuclear meet growth as power-sector emissions hold steady.

✅ Asia drives >70% of demand growth

✅ Renewables and nuclear meet most new supply

✅ CO2 intensity declines; grid flexibility vital

The world’s electricity demand growth slowed only slightly in 2022, despite headwinds from the energy crisis, and is expected to accelerate in the years ahead

Renewables are set to dominate the growth of the world’s electricity supply over the next three years as, renewables eclipse coal in global generation, together with nuclear power they meet the vast majority of the increase in global demand through to 2025, making significant rises in the power sector’s carbon emissions unlikely, according to a new IEA report.

After slowing slightly last year to 2% amid the turmoil of the global energy crisis and exceptional weather conditions in some regions, the growth in world electricity demand is expected to accelerate to an average of 3% over the next three years, the IEA’s Electricity Market Report 2023 finds. Emerging and developing economies in Asia are the driving forces behind this faster pace, which is a step up from average growth of 2.4% during the years before the pandemic and above pre-pandemic levels globally.

More than 70% of the increase in global electricity demand over the next three years is expected to come from China, India and Southeast Asia, as Asia’s power use nears half of the world by mid-decade, although considerable uncertainties remain over trends in China as its economy emerges from strict Covid restrictions. China’s share of global electricity consumption is currently forecast to rise to a new record of one-third by 2025, up from one-quarter in 2015. At the same time, advanced economies are seeking to expand electricity use to displace fossil fuels in sectors such as transport, heating and industry.

“The world’s growing demand for electricity is set to accelerate, adding more than double Japan’s current electricity consumption over the next three years,” said IEA Executive Director Fatih Birol. “The good news is that renewables and nuclear power are growing quickly enough to meet almost all this additional appetite, suggesting we are close to a tipping point for power sector emissions. Governments now need to enable low-emissions sources to grow even faster and drive down emissions so that the world can ensure secure electricity supplies while reaching climate goals.”

While natural gas-fired power generation in the European Union is forecast to fall in the coming years, as wind and solar outpaced gas in 2022, based on current trends, significant growth in the Middle East is set to partly offset this decrease. Sharp spikes in natural gas prices amid the energy crisis have in turn fuelled soaring electricity prices in some markets, particularly in Europe, prompting debate in policy circles over reforms to power market design.

Meanwhile, expected declines in coal-fired generation in Europe and the Americas are likely to be matched by a rise in the Asia-Pacific region, despite increases in nuclear power deployment and restarts of plants in some countries such as Japan. This means that after reaching an all-time high in 2022, carbon dioxide (CO2) emissions from global power generation are set to remain around the same level through 2025.

The strong growth of renewables means their share of the global power generation mix is forecast to rise from 29% in 2022 to 35% in 2025, with the shares of coal- and gas-fired generation falling. As a result, the CO2 intensity of global power generation will continue to decrease in the coming years. Europe bucked this global trend last year, however. The CO2 intensity of Europe’s power generation increased as a result of higher use of coal and gas amid steep drops in output from both hydropower, due to drought, and nuclear power, due to plant closures and maintenance. This setback will be temporary, though, as Europe’s power generation emissions are expected to decrease on average by about 10% a year through 2025.

Electricity demand trends varied widely by region in 2022. India’s electricity consumption rose strongly, while China’s growth was more subdued due to its zero-Covid policy weighing heavily on economic activity. The United States recorded a robust increase in demand, driven by economic activity and higher residential use amid hotter summer weather and a colder-than-normal winter, even as electricity sales projections continue to decline according to some outlooks.

Demand in the European Union contracted due to unusually mild winter weather and a decline in electricity consumption in the industrial sector, which significantly scaled back production because of high energy prices and supply disruptions caused by Russia’s invasion of Ukraine. The 3.5% decrease in EU demand was its second largest percentage decline since the global financial crisis in 2009, with the largest being the exceptional contraction due to the COVID-19 shock in 2020.

The new IEA report notes that electricity demand and supply worldwide are becoming increasingly weather dependent, with extreme conditions a recurring theme in 2022. In addition to the drought in Europe, there were heatwaves in India, resulting in the country’s highest ever peak in power demand. Similarly, central and eastern regions of China were hit by heatwaves and drought, which caused demand for air conditioning to surge amid reduced hydropower generation in Sichuan province. The United States also saw severe winter storms in December, triggering massive power outages.

These highlight the need for faster decarbonisation and accelerated deployment of clean energy technologies, the report says. At the same time, as the clean energy transition gathers pace, the impact of weather events on electricity demand will intensify due to the increased electrification of heating, while the share of weather-dependent renewables will continue to grow in the generation mix. In such a world, increasing the flexibility of power systems, which are under growing strain across grids and markets, while ensuring security of supply and resilience of networks will be crucial.

Canada Net-Zero Electricity 2035 aligns policy and investments with renewables, wind, solar, hydro, storage, and transmission to power electrification of EVs and heat pumps, guided by a stringent clean electricity standard and carbon pricing.

Key Points

A 2035 plan for a zero-emissions grid using renewables, storage and transmission to electrify transport and homes.

✅ Wind, solar, and hydro backed by battery storage and reservoirs

✅ Interprovincial transmission expands reliability and lowers costs

✅ Stringent clean electricity standard and full carbon pricing

By Tom Green
Senior Climate Policy Advisor

Electric vehicles are making inroads in some areas of Canada. But as their numbers grow, will there be enough electrical power for them, and for all the buildings and the industries that are also switching to electricity?

Canada – along with the United States, the European Union and the United Kingdom – is committed to a “net-zero electricity grid by 2035 policy goal”. This target is consistent with the Paris Agreement’s ambition of staying below 1.5 C of global warming, compared with pre-industrial levels.

This target also gives countries their best chance of energy security, as laid out in landmark reports over the past year from the International Energy Agency and the Intergovernmental Panel on Climate Change. A new federal regulation in the form of a clean electricity standard is being developed, but will it be stringent enough to set us up for climate success and avoid dead ends?

Canada starts this work from a relatively low emissions-intensity grid, powered largely by hydroelectricity. However, some provinces such as Alberta, Saskatchewan, Nova Scotia and New Brunswick still have predominantly fossil fuel-powered electricity. Plus, there is a risk of more natural gas generation of electricity in the coming years in most provinces without new federal and provincial regulations.

This means the transition of Canada’s electricity system must solve two problems at once. It must first clean up the existing electricity system, but it must also meet future electricity needs from zero-emissions sources while overall electricity capacity doubles or even triples by 2050.

Canada has enormous potential for renewable generation, even though it remains a solar power laggard in deployment to date. Wind, solar and energy storage are proven, affordable technologies that can be produced here in Canada, while avoiding the volatility of global fossil fuel markets.

As wind and solar have become the cheapest forms of electricity generation in history, we’re already seeing foreign governments and utilities ramp up renewable projects at the pace and scale that would be needed here in Canada, highlighting a significant global electricity market opportunity for Canadian firms at home. In 2020, 280 gigawatts of new capacity was added globally – a 45 per cent increase over the previous year. In Canada, since 2010, annual growth in renewables has so far averaged less than three per cent.

So why aren’t we moving full steam – or electron – ahead? With countries around the world bringing in wind and solar for new generation, why is there so much delay and doubt in Canada, even as analyses explore why the U.S. grid isn’t 100% renewable and remaining barriers?

The modelling team drew on a dataset that accounts for how wind and solar potential varies across the country, through the weeks of the year and the hours of each day. The models provide solutions for the most cost-effective new generation, storage and transmission to add to the grid while ensuring electricity generation meets demand reliably every hour of the year.

The David Suzuki Foundation partnered with the University of Victoria to model the electricity grid of the future.

To better understand future electricity demand, a second modelling team was asked to explore a future when homes and businesses are aggressively electrified; fossil fuel furnaces and boilers are retired and replaced with electric heat pumps; and gasoline and diesel cars are replaced by electric vehicles and public transit. It also dialed up investments in energy efficiency to further reduce the need for energy. These hourly electricity-demand projections were fed back to the models developed at the University of Victoria.

The results? It is possible to meet Canada’s needs for clean electricity reliably and affordably through a focus on expanding wind and solar generation capacity, complemented with new transmission connections between provinces, and other grid improvements.

How is it that such high levels of variable wind and solar can be added to the grid while keeping the lights on 24/7? The model took full advantage of the country’s existing hydroelectric reservoirs, using them as giant batteries, storing water behind the dams when wind and solar generation was high to be used later when renewable generation is low, or when demand is particularly high. The model also invested in more transmission to enable expanded electricity trade between provinces and energy storage in the form of batteries to smooth out the supply of electricity.

Not only is it possible, but the renewable pathway is the safe bet.

There’s no doubt it will take unprecedented effort and scale to transform Canada’s electricity systems. The high electrification pathway would require an 18-fold increase over today’s renewable electricity capacity, deploying an unprecedented amount of new wind, solar and energy storage projects every year from now to 2050. Although the scale seems daunting, countries such as Germany are demonstrating that this pace and scale is possible.

The modelling also showed that small modular nuclear reactors (SMRs) are neither necessary nor cost-effective, making them a poor candidate for continued government subsidies. Likewise, we presented pathways with no need for continued fossil fuel generation with carbon capture and storage (CCS) – an expensive technology with a global track record of burning through public funds while allowing fossil fuel use to expand and while capturing a smaller proportion of the smokestack carbon than promised. We believe that Canada should terminate the significant subsidies and supports it is giving to fossil fuel companies and redirect this support to renewable electricity, energy efficiency and energy affordability programming.

The transition to clean electricity would come with new employment for people living in Canada. Building tomorrow’s grid will support more than 75,000 full-time jobs each year in construction, operation and maintenance of wind, solar and transmission facilities alone.

Regardless of the path chosen, all energy projects in Canada take place on unceded Indigenous territories or treaty land. Decolonizing power structures with benefits to Indigenous communities is imperative. Upholding Indigenous rights and title, ensuring ownership opportunities and decision-making and direct support for Indigenous communities are all essential in how this transition takes place.

Wind, solar, storage and smart grid technologies are evolving rapidly, but our understanding of the possibilities they offer for a zero-emissions future, including debates over clean energy’s dirty secret in some supply chains, appears to be lagging behind reality. As the Institut de L’énergie Trottier observed, decarbonization costs have fallen faster than modellers anticipated.

The shape of tomorrow’s grid will largely depend on policy decisions made today. It’s now up to people living in Canada and their elected representatives to create the right conditions for a renewable revolution that could make the country electric, connected and clean in the years ahead.

To avoid a costly dash-to-gas that will strand assets and to secure early emissions reductions, the electricity sector needs to be fully exposed to the carbon price. The federal government’s announcement that it will move forward with a clean electricity standard – requiring net-zero emissions in the electricity sector by 2035 – will help if the standard is stringent.

Federal funding to encourage provinces to expand interprovincial transmission, including recent grid modernization investments now underway will also move us ahead. At the provincial level, electricity system governance – from utility commission mandates to electricity markets design – needs to be reformed quickly to encourage investments in renewable generation. As fossil fuels are swapped out across the economy, more and more of a household’s total energy bill will come from a local electric utility, so a national energy poverty strategy focused on low-income and equity-seeking households must be a priority.

The payoff from this policy package? Plentiful, reliable, affordable electricity that brings better outcomes for community health and resilience while helping to avoid the worst impacts of climate change.

UK-EU EV Tariffs 2024 threaten a 10% levy under Brexit rules of origin, raising electric vehicle prices, straining battery supply chains, and risking a price war for manufacturers, consumers, and climate targets across automotive market.

Key Points

Tariffs from Brexit rules of origin imposing 10% duties on EVs, raising UK prices amid battery and supply chain gaps.

✅ 10% tariffs if rules of origin thresholds are unmet

✅ Price hikes on UK EVs, led by Tesla Model Y

✅ Battery supply gaps strain UK and EU manufacturers

Electric cars will cost British motorists an extra £6,000 if Rishi Sunak fails to strike a post-Brexit deal with the EU on tariffs, industry bosses have told The Independent.

UK manufacturers warned of a “devastating price war” on consumers, echoing UK concern over higher EV prices across the market – threatening both the electric vehicle (EV) market and the UK’s climate change commitments – if tariffs are enforced in January 2024.

In the latest major Brexit row, the Sunak government is pushing the European Commission to agree to delay the costly new rules, even as the UK readies for rising EV adoption across the economy, set to come in at the start of next year as part of Boris Johnson’s Brexit trade deal.

But Brussels has shown no sign it is willing to budge – even as Washington has announced a 100% tariff on Chinese-made EVs this year – leaving business leaders in despair about the impact of 10 per cent tariffs on exports on Britain’s car industry.

The tariffs would increase the price of a new Tesla Model Y – the UK’s most popular electric vehicle – by £6,000 or more, according to a new report by the Independent Commission on UK-EU Relations.

“For the sake of our economy and our planet, the government has a responsibility to get round the table with the EU, fix this and fix the raft of other issues with the Brexit deal,” said commission director Mike Buckley.

The new rules of origin agreed in the Brexit trade and cooperation agreement (TCA) require 45 per cent of an electric car’s value, as the age of electric cars accelerates, to originate in the UK or EU to qualify for trade without tariffs.

The British auto industry has warned the 2024 rules pose an “existential threat” to sales because of the lack of domestic batteries to meet the rules, even as EV adoption within the decade is widely expected to surge – pleading for a delay until 2027.

The VDA – the lobby group for Germany’s car industry – has also called for an “urgent” move to delay, warning that the rules create a “significant competitive disadvantage” for European carmarkers in relation to China, where tariffs on Chinese EVs are reshaping global trade, and other Asian competitors.

The new report by the Independent Commission on UK-EU Relations – backed by the manufacturers’ body Make UK and the British Chamber of Commerce – warns that the January tariffs will immediately push up costs and hit electric vehicle sales, despite UK EV inquiries surging during the fuel supply crisis in recent years.

Electric Car Motors convert electricity to torque via rotor-stator magnetic fields, using AC/DC inverters, permanent magnets or induction designs; they power EV powertrains efficiently and enable regenerative braking for energy recovery and control.

Key Points

Electric car motors turn electrical energy into wheel torque using rotor-stator fields, inverters, and AC or DC control.

✅ AC induction, PMSM, BLDC, and reluctance architectures explained

✅ Inverters manage AC/DC, voltage, and motor speed via frequency

✅ Regenerative braking recovers energy and reduces wear

When was the last time you stopped to think about how electric cars actually work, especially if you're wondering whether to buy an electric car today? We superfans of the car biz have mostly developed a reasonable understanding of how combustion powertrains work. Most of us can visualize fuel and air entering a combustion chamber, exploding, pushing a piston down, and rotating a crankshaft that ultimately turns the wheels. We generally understand the differences between inline, flat, vee-shaped, and maybe even Wankel rotary combustion engines.

Mechanical engineering concepts such as these are comparatively easy to comprehend. But it's probably a fair bet to wager that only a minority of folks reading this can explain on a bar napkin exactly how invisible electrons turn a car's wheels or how a permanent-magnet motor differs from an AC induction one. Electrical engineering can seem like black magic and witchcraft to car nuts, so it's time to demystify this bold new world of electromobility, with the age of electric cars arriving ahead of schedule.

How Electric Cars Work: Motors
It has to do with magnetism and the natural interplay between electric fields and magnetic fields. When an electrical circuit closes allowing electrons to move along a wire, those moving electrons generate an electromagnetic field complete with a north and a south pole. When this happens in the presence of another magnetic field—either from a different batch of speeding electrons or from Wile E. Coyote's giant ACME horseshoe magnet, those opposite poles attract, and like poles repel each other.

Electric motors work by mounting one set of magnets or electromagnets to a shaft and another set to a housing surrounding that shaft. By periodically reversing the polarity (swapping the north and south poles) of one set of electromagnets, the motor leverages these attracting and repelling forces to rotate the shaft, thereby converting electricity into torque and ultimately turning the wheels, in a sector where the electric motor market is growing rapidly worldwide. Conversely—as in the case of regenerative braking—these magnetic/electromagnetic forces can transform motion back into electricity.

How Electric Cars Work: AC Or DC?
The electricity supplied to your home arrives as alternating current (AC), and bidirectional charging means EVs can power homes for days as needed, so-called because the north/south or plus/minus polarity of the power changes (alternates) 60 times per second. (That is, in the United States and other countries operating at 110 volts; countries with a 220-volt standard typically use 50-Hz AC.) Direct current (DC) is what goes into and comes out of the + and - poles of every battery. As noted above, motors require alternating current to spin. Without it, the electromagnetic force would simply lock their north and south poles together. It's the cycle of continually switching north and south that keeps a motor spinning.

Today's electric cars are designed to manage both AC and DC energy on board. The battery stores and dispenses DC current, but again, the motor needs AC. When recharging the battery, and with increasing grid coordination enabling flexibility, the energy comes into the onboard charger as AC current during Level 1 and Level 2 charging and as DC high-voltage current on Level 3 "fast chargers." Sophisticated power electronics (which we will not attempt to explain here) handle the multiple onboard AC/DC conversions while stepping the voltage up and down from 100 to 800 volts of charging power to battery/motor system voltages of 350-800 volts to the many vehicle lighting, infotainment, and chassis functions that require 12-48-volt DC electricity.

How Electric Cars Work: What Types Of Motors?
DC Motor (Brushed): Yes, we just said AC makes the motor go around, and these old-style motors that powered early EVs of the 1900s are no different. DC current from the battery is delivered to the rotor windings via spring-loaded "brushes" of carbon or lead that energize spinning contacts connected to wire windings. Every few degrees of rotation, the brushes energize a new set of contacts; this continually reverses the polarity of the electromagnet on the rotor as the motor shaft turns. (This ring of contacts is known as the commutator).

The housing surrounding the rotor's electromagnetic windings typically features permanent magnets. (A "series DC" or so-called "universal motor" may use an electromagnetic stator.) Advantages are low initial cost, high reliability, and ease of motor control. Varying the voltage regulates the motor's speed, while changing the current controls its torque. Disadvantages include a lower lifespan and the cost of maintaining the brushes and contacts. This motor is seldom used in transportation today, save for some Indian railway locomotives.

Brushless DC Motor (BLDC): The brushes and their maintenance are eliminated by moving the permanent magnets to the rotor, placing the electromagnets on the stator (housing), and using an external motor controller to alternately switch the various field windings from plus to minus, thereby generating the rotating magnetic field.

Advantages are a long lifespan, low maintenance, and high efficiency. Disadvantages are higher initial cost and more complicated motor speed controllers that typically require three Hall-effect sensors to get the stator-winding current phased correctly. That switching of the stator windings can result in "torque ripple"—periodic increases and decreases in the delivered torque. This type of motor is popular for smaller vehicles like electric bikes and scooters, and it's used in some ancillary automotive applications like electric power steering assist.

Permanent-Magnet Synchronous Motor (PMSM): Physically, the BLDC and PMSM motors look nearly identical. Both feature permanent magnets on the rotor and field windings in the stator. The key difference is that instead of using DC current and switching various windings on and off periodically to spin the permanent magnets, the PMSM functions on continuous sinusoidal AC current. This means it suffers no torque ripple and needs only one Hall-effect sensor to determine rotor speed and position, so it's more efficient and quieter.

The word "synchronous" indicates the rotor spins at the same speed as the magnetic field in the windings. Its big advantages are its power density and strong starting torque. A main disadvantage of any motor with spinning permanent magnets is that it creates "back electromotive force" (EMF) when not powered at speed, which causes drag and heat that can demagnetize the motor. This motor type also sees some duty in power steering and brake systems, but it has become the motor design of choice in most of today's battery electric and hybrid vehicles.

Note that most permanent-magnet motors of all kinds orient their north-south axis perpendicular to the output shaft. This generates "radial (magnetic) flux." A new class of "axial flux" motors orients the magnets' N-S axes parallel to the shaft, usually on pairs of discs sandwiching stationary stator windings in between. The compact, high-torque axial flux orientation of these so-called "pancake motors" can be applied to either BLDC or PMSM type motors.

AC Induction: For this motor, we toss out the permanent magnets on the rotor (and their increasingly scarce rare earth materials) and keep the AC current flowing through stator windings as in the PMSM motor above.

Standing in for the magnets is a concept Nikola Tesla patented in 1888: As AC current flows through various windings in the stator, the windings generate a rotating field of magnetic flux. As these magnetic lines pass through perpendicular windings on a rotor, they induce an electric current. This then generates another magnetic force that induces the rotor to turn. Because this force is only induced when the magnetic field lines cross the rotor windings, the rotor will experience no torque or force if it rotates at the same (synchronous) speed as the rotating magnetic field.

This means AC induction motors are inherently asynchronous. Rotor speed is controlled by varying the alternating current's frequency. At light loads, the inverter controlling the motor can reduce voltage to reduce magnetic losses and improve efficiency. Depowering an induction motor during cruising when it isn't needed eliminates the drag created by a permanent-magnet motor, while dual-motor EVs using PMSM motors on both axles must always power all motors. Peak efficiency may be slightly greater for BLDC or PMSM designs, but AC induction motors often achieve higher average efficiency. Another small trade-off is slightly lower starting torque than PMSM. The GM EV1 of the mid-1990s and most Teslas have employed AC Induction motors, despite skepticism about an EV revolution in some quarters.

Reluctance Motor: Think of "reluctance" as magnetic resistance: the degree to which an object opposes magnetic flux. A reluctance motor's stator features multiple electromagnet poles—concentrated windings that form highly localized north or south poles. In a switched reluctance motor (SRM), the rotor is made of soft magnetic material such as laminated silicon steel, with multiple projections designed to interact with the stator's poles. The various electromagnet poles are turned on and off in much the same way the field windings in a BLDC motor are. Using an unequal number of stator and rotor poles ensures some poles are aligned (for minimum reluctance), while others are directly in between opposite poles (maximum reluctance). Switching the stator polarity then pulls the rotor around at an asynchronous speed.

A synchronous reluctance motor (SynRM) doesn't rely on this imbalance in the rotor and stator poles. Rather, SynRM motors feature a more distributed winding fed with a sinusoidal AC current as in a PMSM design, with speed regulated by a variable-frequency drive, and an elaborately shaped rotor with voids shaped like magnetic flux lines to optimize reluctance.

The latest trend is to place small permanent magnets (often simpler ferrite ones) in some of these voids to take advantage of both magnetic and reluctance torque while minimizing cost and the back EMF (or counter-electromotive force) high-speed inefficiencies that permanent-magnet motors suffer.

Advantages include lower cost, simplicity, and high efficiency. Disadvantages can include noise and torque ripple (especially for switched reluctance motors). Toyota introduced an internal permanent-magnet synchronous reluctance motor (IPM SynRM) on the Prius, and Tesla now pairs one such motor with an AC induction motor on its Dual Motor models. Tesla also uses IPM SynRM as the single motor for its rear-drive models.

Electric motors may never sing like a small-block or a flat-plane crank Ferrari. But maybe, a decade or so from now, we'll regard the Tesla Plaid powertrain as fondly as we do those engines, even as industry leaders note that mainstream adoption faces hurdles, and every car lover will be able to describe in intimate detail what kind of motors it uses.

Canadian Electric Bus Fleet leads North America as Toronto's TTC deploys 59 battery-electric, zero-emission buses, advancing public transit decarbonization with charging infrastructure, federal funding, lower maintenance, and lifecycle cost savings for a low-carbon urban future.

Key Points

Canada's leading battery-electric transit push, led by Toronto's TTC, scaling zero-emission buses and charging.

✅ Largest battery-electric bus fleet in North America

✅ TTC trials BYD, New Flyer, Proterra for range and reliability

✅ Charging infrastructure, funding, and specs drive 2040 zero-emissions

The largest battery-powered electric bus fleet in North America is Canadian. Toronto's transit system is now running 59 electric buses from three suppliers, and Edmonton's first electric bus is now on the road as well. And Canadian pioneers such as Toronto offer lessons for other transit systems aiming to transition to greener fleets for the low-carbon economy of the future.

Diesel buses are some of the noisier, more polluting vehicles on urban roads. Going electric could have big benefits, even though 18% of Canada's 2019 electricity from fossil fuels remains a factor.

Emissions reductions are the main reason the federal government aims to add 5,000 electric buses to Canada's transit and school fleets by the end of 2024. New funding announced this week as part of the government's fall fiscal update could also give programs to electrify transit systems a boost.

"You are seeing huge movement towards all-electric," said Bem Case, the Toronto Transit Commission's head of vehicle programs. "I think all of the transit agencies are starting to see what we're seeing ... the broader benefits."

While Vancouver has been running electric trolley buses (more than 200, in fact), many cities (including Vancouver) are now switching their diesel buses to battery-electric buses in Metro Vancouver that don't require overhead wires and can run on regular bus routes.

The TTC got approval from its board to buy its first 30 battery-electric buses in November 2017. Its plan is to have a zero-emissions fleet by 2040.

That's a crucial part of Toronto's plan to meet its 2050 greenhouse gas targets, which requires 100 per cent of vehicles to transition to low-carbon energy by then.

But Case said the transition can't happen overnight. 

Finding the right bus
For one thing, just finding the right bus isn't easy.

"There's no bus, by any manufacturer, that's been in service for the entire life of a bus, which is 12 years," Case said.

"And so really, until then, we don't have enough experience, nor does anyone else in the industry, have enough experience to commit to an all-electric fleet immediately."

In fact, Case said, there are only three manufacturers that make suitable long-range buses — the kind needed in a city the size of Toronto.

Having never bought electric buses before, the city had no specifications for what it needed in an electric bus, so it decided to try all three suppliers: Winnipeg-based New Flyer; BYD, which is headquartered in Shenzhen, China, but built the TTC buses at its Newmarket, Ont. facility; and California-based Proterra.

They all had their strengths and weaknesses, based on their backgrounds as a traditional non-electric bus manufacturer, a battery maker and a vehicle technology and design startup, respectively.

"Each bus type has its own potential challenges." Case said all three manufacturers are working to resolve any adoption challenges as quickly as possible.

But the biggest challenge of all, Case said, is getting the infrastructure in place. 

"There's no playbook, really, for implementing charging infrastructure," he said.

Each bus type needed their own chargers, in some cases using different types of current. Each type has been installed in a different garage in partnership with local utility Toronto Hydro.

Buying and installing them represented about $70 million, or about half the cost of acquiring Toronto's first 60 electric buses. The $140 million project was funded by the federal Public Transit Infrastructure Fund.

Case said it takes about three hours to charge a battery that has been fully depleted. To maximize use of the bus, it's typically put on a long route in the morning, covering 200 to 250 kilometres. Then it's partially charged and put on a shorter run in the late afternoon.

"That way we get as much mileage on the buses as we can."

Cost and reliability?
Besides the infrastructure cost of chargers, each electric bus can cost $200,000 to $500,000 more per bus than an average $750,000 diesel bus. 

Case acknowledges that is "significantly" more expensive, but it is offset by fuel savings over time, as electricity costs are cheaper. Because the electric buses have fewer parts than diesel buses, maintenance costs are also about 25 per cent lower and the buses are expected to be more reliable.

As with many new technologies, the cost of electric buses is also falling over time.

Case expects they will eventually get to the point where the total life-cycle cost of an electric and a diesel bus are comparable, and the electric bus may even save money in the long run.

As of this fall, all but one of the 60 new electric buses have been put into service. The last one is expected to hit the road in early December.

Summer testing showed that air conditioning the buses reduced the battery capacity by about 15 per cent. 

But the TTC needs to see how much of the battery capacity is consumed by heating in winter, at least when the temperature is above 5 C. Below that, a diesel-powered heater kicks in.

Once testing is complete, the TTC plans to develop specifications for its electric bus fleet and order 300 more in 2023, for delivery between 2023 and 2025.

Potential benefits
Even with some diesel heating, the TTC estimates electric buses reduce fuel usage by 70 to 80 per cent. If its whole fleet were switched to electric buses, it could save $50 million to $70 million in fuel a year and 150 tonnes of greenhouse gases per bus per year, or 340,000 tonnes for the entire fleet.

Other than greenhouse gases, electric buses also generate fewer emissions of other pollutants. They're also quieter, creating a more comfortable urban environment for pedestrians and cyclists.

But the benefits could potentially go far beyond the local city.

"If the public agencies start electrifying their fleet and their service is very demanding, I think they'll demonstrate to the broader transportation industry that it is possible," Case said.

"And that's where you'll get the real gains for the environment."

Alex Milovanoff, a postdoctoral researcher in the University of Toronto's department of civil engineering, did a U of T EV study that suggested electrified transit has a crucial role to play in the low-carbon economy of the future.

His calculations show that 90 per cent of U.S. passenger vehicles — 300 million — would need to be electric by 2050 to reach targets under the global Paris Agreement to fight climate change.

And that would put a huge strain on resources, including both the mining of metals, such as lithium and cobalt, that are used in electric vehicle batteries and the electrical grid itself.

A better solution, he showed, was combining the transition to electric vehicles with a reduction in the number of private vehicles, and higher usage of transit, cycling and walking.

"Then that becomes a feasible picture," he said.

What's needed to make the transition
But in order to make that happen, governments need to make investments and navigate the 2035 EV mandate debate on timelines, he added.

That includes subsidies for buying electric buses and building charging stations so transit agencies don't need to make fares too high. But it also includes more general improvements to the range and reliability of transit infrastructure.

"Electrifying the bus fleet is only efficient if we have a large public transit fleet and if we have many buses on the road and if people take them," Milovanoff said.

In its fall economic update on Monday, the federal government announced $150 million over three years to speed up the installation of zero-emission vehicle infrastructure.

Josipa Petrunic, CEO of the Canadian Urban Transit Research and Innovation Consortium, a non-profit organization focused on zero-carbon mobility and transportation, said that in the past, similar funding has paid for high-powered charging systems for transit systems in B.C. and Ontario. But that's only a small part of what's needed, she said.

"Infrastructure Canada needs to come to the table with the cash for the buses and the whole rest of the system."

She said funding is needed for:

Feasibility studies to figure out how many and what kinds of buses are needed for different routes in different transit systems.

Targets and incentives to motivate transit systems to make the switch.

Incentives to encourage Canadian procurement to build the industry in Canada.

Technology to collect and share data on the performance of electric vehicles so transit systems can make the best-possible decisions to meet the needs of their riders.

Petrunic said that a positive side-effect of electrifying transit systems is that the infrastructure can support, in addition to buses, electric trucks for moving freight.

"It's not a lot given that we have 15,000 buses out there in the transit fleet," she said.

"But we should be able to get a lot further ahead if we match the city commitments to zero emissions with federal and provincial funding for jobs creating zero-emissions technologies."

Inflation Reduction Act Clean Energy drives EV adoption and renewable power, but grid interconnection, permitting, and supply chain bottlenecks slow wind, solar, and offshore projects, risking emissions targets despite domestic manufacturing growth and tax incentives.

Key Points

An IRA push to scale EVs and renewables, meeting EV goals but lagging wind and solar amid grid and permitting delays.

✅ EV sales up 50%, 9.2% of 2023 new cars; growth may moderate.

✅ 32.3 GW added, below 46-79 GW/year needed for climate targets.

✅ Grid, permitting, and supply chain delays bottleneck wind and solar.

A year and a half following President Biden's enactment of an ambitious climate change bill, the landscape of the United States' clean energy transition, shaped by 2021 electricity lessons, presents a mix of successes and challenges. A recent study by a consortium of research organizations highlights that while electric vehicle (EV) sales have surged, aligning with the law's projections, the expansion of renewable energy sources like wind and solar has encountered significant hurdles.

The legislation, known as the Inflation Reduction Act, aimed for a dual thrust in America's climate strategy: boosting EV adoption, alongside EPA emission limits, and significantly increasing the generation of electricity from renewable resources. The Act, passed in 2022, was anticipated to propel the United States toward reducing its greenhouse gas emissions by approximately 40 percent from 2005 levels by the end of this decade, backed by extensive financial incentives for clean energy advancements.

Electric vehicle sales have indeed seen a remarkable uptick, with a more than 50 percent increase over the past year, as EV sales surge into 2024 across the market, culminating in EVs comprising 9.2 percent of all new car sales in the United States in 2023. This growth trajectory met the upper range of analysts' predictions post-law enactment, signaling a strong start toward achieving the Act's emission reduction targets.

However, the EV market faces uncertainties regarding the sustainability of this rapid growth. The initial surge in sales was largely driven by early adopters, and the market now confronts challenges such as high prices and limited charging infrastructure, while EVs still trail gas cars in overall market share. Despite these concerns, projections suggest that even a slowdown to 30-40 percent growth in EV sales for 2024 would align with the law's emission goals.

The renewable energy sector's progress is less straightforward. Despite achieving a record addition of 32.3 gigawatts of clean electricity capacity in the past year, the pace falls short of the projected 46 to 79 gigawatts needed annually to meet the United States' climate objectives. While there is potential for about 60 gigawatts of projects in the pipeline for this year, not all are expected to materialize on schedule, indicating a lag in the deployment of new renewable energy sources.

Logistical challenges are a significant barrier to scaling up renewable energy, especially as EV-driven electricity demand rises in the coming years. Lengthy grid connection processes, permitting delays, and local opposition hinder wind and solar project developments. Moreover, ambitious plans for offshore wind farms are hampered by supply chain issues and regulatory constraints.

To achieve the Inflation Reduction Act's ambitious targets, the United States needs to add 70 to 126 gigawatts of renewable capacity annually from 2025 to 2030—a formidable task given the current logistical and regulatory bottlenecks. The analysis underscores the urgency of addressing these non-cost barriers to unlock the full potential of the law's clean energy and emissions reduction ambitions.

In addition to promoting clean energy generation and EV adoption, the Inflation Reduction Act has spurred domestic manufacturing of clean energy technologies. With $44 billion invested in U.S. clean-energy manufacturing last year, this aspect of the law has seen considerable success, and permanent clean energy tax credits are being debated to sustain momentum, demonstrating the Act's capacity to drive economic and industrial transformation.

The law's impact extends to emerging clean energy technologies, offering tax incentives for advanced nuclear reactors, renewable hydrogen production, and carbon capture and storage projects. While these initiatives hold promise for further emissions reductions, their development and deployment are still in the early stages, with tangible outcomes expected in the longer term.

While the Inflation Reduction Act has catalyzed significant strides in certain areas of the United States' clean energy transition, including an EV inflection point in adoption trends, it faces substantial hurdles in fully realizing its objectives. Overcoming logistical, regulatory, and market challenges will be crucial for the nation to stay on course toward its ambitious climate goals, underscoring the need for continued innovation, investment, and policy refinement in the journey toward a sustainable energy future.
