Elon Musk says cheaper, more powerful electric vehicle batteries are 3 years off

UCS EV emissions study shows electric vehicles produce lower life-cycle emissions than gasoline cars across all states, factoring tailpipe, grid mix, power plant sources, and renewable energy, delivering mpg-equivalent advantages nationwide.

Key Points

UCS study comparing EV and gas life-cycle emissions, finding EVs cleaner than new gas cars in every U.S. region.

✅ Average EV equals 93 mpg gas car on emissions.

✅ Cleaner than 50 mpg gas cars in 97% of U.S.

✅ Regional grid mix included: tailpipe to power plant.

One of the cautions cited by electric vehicle (EV) naysayers is that they merely shift emissions from the tailpipe to the local grid’s power source, implicating state power grids as a whole, and some charging efficiency claims get the math wrong, too. And while there is a kernel of truth to this notion—they’re indeed more benign to the environment in states where renewable energy resources are prevalent—the average EV is cleaner to run than the average new gasoline vehicle in all 50 states. 

That’s according to a just-released study conducted the Union of Concerned Scientists (UCS), which determined that global warming emissions related to EVs has fallen by 15 percent since 2018. For 97 percent of the U.S., driving an electric car is equivalent or better for the planet than a gasoline-powered model that gets 50 mpg. 

In fact, the organization says the average EV currently on the market is now on a par, environmentally, with an internal combustion vehicle that’s rated at 93 mpg. The most efficient gas-driven model sold in the U.S. gets 59 mpg, and EV sales still trail gas cars despite such comparisons, with the average new petrol-powered car at 31 mpg.

For a gasoline car, the UCS considers a vehicle’s tailpipe emissions, as well as the effects of pumping crude oil from the ground, transporting it to a refinery, creating gasoline, and transporting it to filling stations. For electric vehicles, the UCS’ environmental estimates include both emissions from the power plants themselves, along with those created by the production of coal, natural gas or other fossil fuels used to generate electricity, and they are often mischaracterized by claims about battery manufacturing emissions that don’t hold up. 

Of course the degree to which an EV ultimately affects the atmosphere still varies from one part of the country to another, depending on the local power source. In some parts of the country, driving the average new gasoline car will produce four to eight times the emissions of the average EV, a fact worth noting for those wondering if it’s the time to buy an electric car today. The UCS says the average EV driven in upstate New York produces total emissions that would be equivalent to a gasoline car that gets an impossible 255-mpg. In even the dirtiest areas for generating electricity, EVs are responsible for as much emissions as a conventionally powered car that gets over 40 mpg.

California EV V2G explores bi-directional charging, smart charging, and demand response to enhance grid reliability. CPUC, PG&E, and automakers test incentives aligning charging with solar and wind, helping prevent blackouts and curtailment.

Key Points

California EV V2G uses two-way charging and smart incentives to support grid reliability during peak demand.

✅ CPUC studies feasibility, timelines, and cost barriers to V2G

✅ Incentives shift charging to align with solar, wind, off-peak hours

✅ High-cost bidirectional chargers and warranties remain hurdles

California energy regulators are eyeing the power stored in electric vehicles as they hunt for ways to avoid blackouts caused by extreme weather.

While few EV and their charging ports are equipped to deliver electricity back into the grid during emergencies, the California Public Utilities Commission wants more data on it as the agency rules on steps utilities must take to ensure they have enough power for this summer and next year. A draft CPUC decision due to be discussed this week asks about the feasibility of reversing the charge when needed (Energywire, March 8).

“Very few [EVs], maybe a couple of thousand at the most, can give power to the grid, and even fewer are connected into a charger that can do it,” said Gil Tal, director of the Plug-in Hybrid & Electric Vehicle Research Center at the University of California, Davis. EVs that feature the ability “have it at a more experimental level.”

The issue arises as California, where about half of all U.S. EVs are purchased, examines what role the vehicles can play in keeping lights on and refrigerators running and how a much bigger grid will support them in the long term. Even if grid operators can’t pull from EV batteries en masse, experts say cash and other incentives can prompt drivers to shift charging times, boosting grid stability.

“What we can do is not charge the electric cars at times of high demand” such as during heat waves, Tal said.

The EV focus comes after California’s grid manager last summer imposed rolling blackouts when power supplies ran short during a record-shattering heat wave. State energy regulators across the U.S., as EVs challenge state grids, are also looking at their disaster preparedness as Texas recovers from a winter storm last month that cut off electricity for more than 4 million homes and businesses there.

California’s EV efforts can help other states as they add more renewable power to their grids, said Adam Langton, energy services manager at BMW of North America.

That automaker ran a pilot program with San Francisco-based utility Pacific Gas & Electric Co. (PG&E) looking at whether money and other incentives could prompt EV drivers to charge their cars at different times. The payments successfully shifted charging to the middle of the night, when wind power often is plentiful. It also moved some repowering to mornings and early afternoons, when there’s abundant solar energy.

“That can be a tool that the utilities can use to deal with supply issues,” Langton said. “What our research has shown is that vehicles can contribute to [conservation] needs and emergency supply by shifting their charging time.”

Such measures can also help states avoid having to curtail solar production on days when there’s more generation than needed. On many bright days, California has more solar power than it can use.

“As more states add more renewable energy, we think that they’re going to find that EVs complement that really well with smart charging, because grid coordination can get that charging to align with the renewable energy,” Langton said. “It allows to add more and more renewable energy.”

High-cost equipment a hurdle
The CPUC at a future workshop plans to collect information on leveraging EVs to head off power shortages at key times.

But Tal said it will probably take a decade to get enough EVs capable of exporting electricity back to utilities “in high numbers that can make an impact on the grid.”

Barriers to reaching such “vehicle to grid” integration are technical and economic, he said. EVs export direct current and need a device on the other side that can convert it to alternating current, similar to a solar power inverter for rooftop panels.

However, the equipment known as a V2G capable charger is costly. It ranges from $4,500 to $5,500, according to a 2017 National Renewable Energy Laboratory report.

PG&E and Los Angeles-based Southern California Edison already have “expressed doubt that short-term measures could be developed in time to expand EV participation by summer 2021” in V2G programs, the draft CPUC proposal said. The utilities suggested instead that the agency encourage EV owners to participate in initiatives where they’d get paid for reducing power consumption or sell electricity back to the grid when needed, known as demand response programs.

Still, almost all major EV automakers are looking at two-directional charging, Tal said.

“The incentive is you can get more value for the car,” he said. “The disincentive is you add more miles in a way on the car,” because an owner would be discharging to the grid and re-charging, and “the battery has limited life.”

And right now, discharging a vehicle to the grid would violate many warranties, he said. Car manufacturers would need to agree to change that and could call for compensation in return.

Meanwhile, San Diego Gas & Electric Co., a Sempra Energy subsidy, plans to launch a pilot looking at delivering power to the grid from electric school buses. The six buses in the pilot transport students in El Cajon, Calif., east of San Diego.

“The buses are perfect because of their big batteries and predictable schedule,” Jessica Packard, SDG&E spokesperson, said in an email. “Ultimately, we hope to scale up and deploy these kinds of innovations throughout our grid in the future.”

She declined to say how much power the buses could deliver because the project isn’t yet operating. It’s set to start later this year.

Mobility needs
While BMW and PG&E did not review vehicle-to-grid power transfers in their own 2017 research ending last year, one study in Delaware did. But it was in a university setting about eight years ago and didn’t look at actual drivers, said Langton with BMW.

In their own findings from the San Francisco Bay Area pilot program, BMW and PG&E found that incentives could quickly change driver behavior in terms of charging.

Technology helps: Most new EVs have timers that allow the driver to control when to charge and when to stop charging. Langton said the pilot program got drivers to have their cars charge from roughly 2 to 6 a.m., when electricity rates typically are lowest.

There can be a lot of solar energy during the day, but in summer, optimum charging times get more complicated in California, he said. People want to run their air conditioners during peak heat hours, so it’s important to be able to get EV drivers to shift to less congested times, he said.

With the right incentives or messaging, Langton said, the pilot persuaded drivers to move charging from 10 a.m. to 2 p.m. or noon to 4 p.m. BMW technology allowed for detailed information on battery charge level, ideal charging times and other EV data to be transmitted electronically after plugging in.

The findings are a good first step toward future vehicle-to-grid integration, Langton added.

“One of the things we really pay attention to when we do smart charging is, ‘How does the driver’s mobility needs figure into shifting their charging?'” he said. “We want to make sure that our customers can always do the driving that they need to do.”

The pilot included safeguards such as an opt-out button if the driver wanted to charge immediately. It also made sure the vehicle had a certain level of minimum charge — 15% to 20% — before the delayed smart charging kicked in.

Vehicle-to-grid technology would need to wrestle with the same concepts in a different way. If a car is getting discharged, the driver would want assurances its battery wouldn’t dip below a level that meets their mobility needs, Langton said.

“If that happened even once to a customer, they would probably not want to participate in these programs in the future,” he said.

One group adding charging stations across the country said it isn’t tweaking pricing based on when drivers charge. That’s to help grow EV purchases, said Robert Barrosa, senior director of sales and marketing at Volkswagen AG subsidiary Electrify America, which operates about 450 charging stations in 45 states.

The company has installed battery storage at more than 100 sites to make sure they can provide power at consistent prices even if California or another state calls for energy conservation.

“It’s very important for vehicle adoption that the customer have that,” Barrosa said.

The company could sell that battery storage back to the grid if there are shortfalls, but some market changes are needed first, particularly in California, he said. That’s because the company buys electricity on the retail side but would be sending it back into the wholesale market.

With that cost differential, Barrosa said, “it doesn’t make sense.”

Canada Offshore Wind Amendments streamline offshore energy regulators in Nova Scotia and Newfoundland and Labrador, enabling green hydrogen, submerged land licences, regional assessments, MPAs standards, while raising fisheries compensation, navigation, and Indigenous consultation considerations.

Key Points

Reforms assign offshore wind to joint regulators, enable seabed licensing, and address fisheries and Indigenous issues.

✅ Assigns wind oversight to Canada-NS and Canada-NL offshore regulators

✅ Introduces single submerged land licence and regional assessments

✅ Addresses fisheries, navigation, MPAs, and Indigenous consultation

Canada's offshore accords with Nova Scotia and Newfoundland and Labrador are being updated to promote development of offshore wind farms, but it's not clear yet whether any compensation will be paid to fishermen displaced by wind farms.

Amendments introduced Tuesday in Ottawa by the federal government assign regulatory authority for wind power to jointly managed offshore boards — now renamed the Canada-Nova Scotia Offshore Energy Regulator and Canada-Newfoundland and Labrador Offshore Energy Regulator.

Previously the boards regulated only offshore oil and gas projects.

The industry association promoting offshore wind development, Marine Renewables Canada, called the changes a crucial step.

"The tabling of the accord act amendments marks the beginning of, really, a new industry, one that can play a significant role in our clean energy future," said  Lisen Bassett, a spokesperson for Marine Renewables Canada. 

Nova Scotia's lone member of the federal cabinet, Immigration Minister Sean Fraser, also talked up prospects at a news conference in Ottawa.

'We have lots of water'

"The potential that we have, particularly when it comes to offshore wind and hydrogen is extraordinary," said Fraser.

"There are real projects, like Vineyard Wind, with real investors talking about real jobs."

Sharing the stage with assembled Liberal MPs from Nova Scotia and Newfoundland and Labrador was Nova Scotia Environment Minister Tim Halman, representing a Progressive Conservative government in Halifax.

"If you've ever visited us or Newfoundland, you know we have lots of water, you know we have lots of wind, and we're gearing up to take advantage of those natural resources in a clean, sustainable way. We're paving the way for projects such as offshore wind, tidal energy in Nova Scotia, and green hydrogen production," said Halman.

Before a call for bids is issued, authorities will identify areas suitable for development, conservation or fishing.

The legislation does not outline compensation to fishermen excluded from offshore areas because of wind farm approvals.

Regional assessments

Federal officials said potential conflicts can be addressed in regional assessments underway in both provinces.

Minister of Natural Resources of Canada Jonathan Wilkinson said fisheries and navigation issues will have to be dealt with.

"Those are things that will have to be addressed in the context of each potential project. But the idea is obviously to ensure that those impacts are not significant," Wilkinson said.

Speaking after the event, Christine Bonnell-Eisnor, chair of what is still called the Canada Nova Scotia Offshore Petroleum Board, said what compensation — if any — will be paid to fishermen has yet to be determined.

"It is a question that we're asking as well. Governments are setting the policy and what terms and conditions would be associated with a sea bed licence. That is a question governments are working on and what compensation would look like for fishers."

Scott Tessier, who chairs  the Newfoundland Board, added "the experience has been the same next door in Nova Scotia, the petroleum sector and the fishing sector have an excellent history of cooperation and communication and I don't expect it look any different for offshore renewable energy projects."

Nova Scotia in a hurry to get going

The legislation says the offshore regulator would promote compensation schemes developed by industry and fishing groups linked to fishing gear.

Nova Scotia is in a hurry to get going.

The Houston government has set a target of issuing five gigawatts of licences for offshore wind by 2030, with leasing starting in 2025, reflecting momentum in the U.S. offshore wind market as well. It is intended largely for green hydrogen production. That's almost twice the province's peak electricity demand in winter, which is 2.2 gigawatts.

The amendments will streamline seabed approvals by creating a single "submerged land" licence, echoing B.C.'s streamlined process for clean energy projects, instead of the exploration, significant discovery and production licences used for petroleum development.

Federal and provincial ministers will issue calls for bids and approve licences, akin to BOEM lease requests seen in the U.S. market.

The amendments will ensure Marine Protected Area's  (MPAs) standards apply in all offshore areas governed by the regulations.

Marine protected areas

Wilkinson suggested, but declined, three times to explicitly state that offshore wind farms would be excluded from within Marine Protected Areas.

After this story was initially published on Tuesday, Natural Resources Canada sent CBC a statement indicating offshore wind farms may be permitted inside MPAs.

Spokesperson Barre Campbell noted that all MPAs established in Canada after April 25, 2019, will be subject to the Department of Fisheries and Oceans new standards that prohibit key industrial activities, including oil and gas exploration, development and production.

"Offshore renewable energy activities and infrastructure are not key industrial activities," Campbell said in a statement.

"Other activities may be prohibited, however, if they are not consistent with the conservation objectives that are established by the relevant department that has or that will establish a marine protected area."

Federal impact assessment process

The new federal impact assessment process will apply in offshore energy development, and recent legal rulings such as the Cornwall wind farm decision highlight how courts can influence project timelines.

For petroleum projects, future significant discovery licences will be limited to 25 years replacing the current indefinite term.

Existing significant discovery licences have been an ongoing exception and are not subject to the 25-year limit. Both offshore energy regulators will be given the authority to fulfil the Crown's duty to consult with Indigenous peoples

Faroe Islands Tidal Kites harness predictable ocean energy with underwater turbines by Minesto, flying figure-eight paths in fjords to amplify tidal power and deliver renewable electricity to SEV's grid near Vestmanna at megawatt scale.

Key Points

Subsea turbines that fly figure-eight paths to harvest tidal currents, delivering reliable renewable power to the grid.

✅ Figure-eight control amplifies speed vs. ambient current

✅ Predictable baseload complementing wind and hydro

✅ 1.2 MW Dragon-class units planned for Faroese fjords

Known as "sea dragons" or "tidal kites", they look like aircraft, but these are in fact high-tech tidal turbines, part of broader ocean and river power efforts generating electricity from the power of the ocean.

The two kites - with a five-metre (16ft) wingspan - move underwater in a figure-of-eight pattern, absorbing energy from the running tide. They are tethered to the fjord seabed by 40-metre metal cables.

Their movement is generated by the lift exerted by the water flow - just as a plane flies by the force of air flowing over its wings.

Other forms of tidal power use technology similar to terrestrial wind turbines, and emerging kite-based wind power shows the concept's versatility, but the kites are something different.

The moving "flight path" allows the kite to sweep a larger area at a speed several times greater than that of the underwater current. This, in turn, enables the machines to amplify the amount of energy generated by the water alone.

An on-board computer steers the kite into the prevailing current, then idles it at slack tide, maintaining a constant depth in the water column. If there were several kites working at once, the machines would be spaced far enough apart to avoid collisions.

The electricity is sent via the tethering cables to others on the seabed, and then to an onshore control station near the coastal town of Vestmanna.

The technology has been developed by Swedish engineering firm Minesto, founded back in 2007 as a spin-off from the country's plane manufacturer, Saab.

The two kites in the Faroe Islands have been contributing energy to Faroe's electricity company SEV, and the islands' national grid, on an experimental basis over the past year.

Each kite can produce enough electricity to power approximately 50 to 70 homes.

But according to Minesto chief executive, Martin Edlund, larger-scale beasts will enter the fjord in 2022.

"The new kites will have a 12-metre wingspan, and can each generate 1.2 megawatts of power [a megawatt is 1,000 kilowatts]," he says. "We believe an array of these Dragon-class kites will produce enough electricity to power half of the households in the Faroes."

The 17 inhabited Faroe islands are an autonomous territory of Denmark. Located halfway between Shetland and Iceland, in a region where U.K. wind lessons resonate, they are home to just over 50,000 people.

Known for their high winds, persistent rainfall and rough seas, the islands have never been an easy place to live. Fishing is the primary industry, accounting for more than 90% of all exports.

The hope for the underwater kites is that they will help the Faroe Islands achieve its target of net-zero emission energy generation by 2030, with advances in wave energy complementing tidal resources along the way.

While hydro-electric power currently contributes around 40% of the islands' energy needs, wind power contributes around 12% and fossil fuels - in the form of diesel imported by sea - still account for almost half.

Mr Edlund says that the kites will be a particularly useful back-up when the weather is calm. "We had an unusual summer in 2021 in Faroes, with about two months with virtually no wind," he says.

"In an island location there is no possibility of bringing in power connections from another country, and tidal energy for remote communities can help, when supplies run low. The tidal motion is almost perpetual, and we see it as a crucial addition to the net zero goals of the next decade."

Minesto has also been testing its kites in Northern Ireland and Wales, where offshore wind in the UK is powering rapid growth, and it plans to install a farm off the coast of Anglesey, plus projects in Taiwan and Florida.

The Faroe Islands' drive towards more environmental sustainability extends to its wider business community, with surging offshore wind investment providing global momentum. The locals have formed a new umbrella organisation - Burðardygt Vinnulív (Faroese Business Sustainability Initiative).

It currently has 12 high-profile members - key players in local business sectors such as hotels, energy, salmon farming, banking and shipping.

The initiative's chief executive - Ana Holden-Peters - believes the strong tradition of working collaboratively in the islands has spurred on the process. "These businesses have committed to sustainability goals which will be independently assessed," she says.

"Our members are asking how they can make a positive contribution to the national effort. When people here take on a new idea, the small scale of our society means it can progress very rapidly."

One of the islands' main salmon exporters - Hiddenfjord - is also doing its bit, by ceasing the air freighting of its fresh fish. Thought to be a global first for the Atlantic salmon industry, it is now exporting solely via sea cargo instead.

According to the firm's managing director Atli Gregersen this will reduce its transportation CO2 emissions by more than 90%. However it is a bold move commercially as it means that its salmon now takes much longer to get to key markets.

For example, using air freight, it could get its salmon to New York City within two days, but it now takes more than a week by sea.

What has made this possible is better chilling technology that keeps the fresh fish constantly very cold, but without the damaging impact of deep freezing it. So the fish is kept at -3C, rather than the -18C or below of typical commercial frozen food transportation.

"It's taken years to perfect a system that maintains premium quality salmon transported for sea freight rather than plane," says Mr Gregersen. "And that includes stress-free harvesting, as well as an unbroken cold-chain that is closely monitored for longer shelf life.

"We hope, having shown it can be done, that other producers will follow our lead - and accept the idea that salmon were never meant to fly."

Back in the Faroe Island's fjords, a firm called Ocean Rainforest is farming seaweed.

The crop is already used for human food, added to cosmetics, and vitamin supplements, but the firm's managing director Olavur Gregersen is especially keen on the potential of fermented seaweed being used as an additive to cattle feed.

He points to research which appears to show that if cows are given seaweed to eat it reduces the amount of methane gas that they exhale.

"A single cow will burp between 200 and 500 litres of methane every day, as it digests," says Mr Gregersen. "For a dairy cow that's three tonnes per animal per year.

"But we have scientific evidence to show that the antioxidants and tannins in seaweed can significantly reduce the development of methane in the animal's stomach. A seaweed farm covering just 10% of the largest planned North Sea wind farm could reduce the methane emissions from Danish dairy cattle by 50%."

The technology that Ocean Rainforest uses to farm its four different species of seaweed is relatively simple. Tiny algal seedlings are affixed to a rope which dangles in the water, and they grow rapidly. The line is lifted using a winch and the seaweed strands simply cut off with a knife. The line goes back into the water, and the seaweed starts growing again.

Currently, Ocean Rainforest is harvesting around 200 tonnes of seaweed per annum in the Faroe Islands, but plans to scale this up to 8,000 tonnes by 2025. Production may also be expanded to other areas in Europe and North America.

U.S. 2023 Utility-Scale Capacity Additions highlight surging solar power, expanding battery storage, wind projects, natural gas plants, and new nuclear reactors, boosting grid reliability in Texas and California with record planned installations.

Key Points

Planned grid expansions led by solar and battery storage, with wind, natural gas, and nuclear increasing U.S. capacity.

✅ 29.1 GW solar planned; Texas and California lead installations.

✅ 9.4 GW battery storage to more than double current capacity.

✅ Natural gas, wind, and 2.2 GW nuclear round out additions.

Developers plan to add 54.5 gigawatts (GW) of new utility-scale electric-generating capacity to the U.S. power grid in 2023, according to our Preliminary Monthly Electric Generator Inventory. More than half of this capacity will be solar power (54%), even as coal generation increase has been reported, followed by battery storage (17%).

Solar

U.S. utility-scale solar capacity has been rising rapidly EIA summer outlook since 2010. Despite its upward trend over the past decade 2018 milestone, additions of utility-scale solar capacity declined by 23% in 2022 compared with 2021. This drop in solar capacity additions was the result of supply chain disruptions and other pandemic-related challenges. We expect that some of those delayed 2022 projects will begin operating in 2023, when developers plan to install 29.1 GW of solar power in the United States. If all of this capacity comes online as planned, 2023 will have the most new utility-scale solar capacity added in a single year, more than doubling the current record (13.4 GW in 2021).

In 2023, the most new solar capacity, by far, will be in Texas (7.7 GW) and California (4.2 GW), together accounting for 41% of planned new solar capacity.

Battery storage

U.S. battery storage capacity has grown rapidly January generation jump over the past couple of years. In 2023, U.S. battery capacity will likely more than double. Developers have reported plans to add 9.4 GW of battery storage to the existing 8.8 GW of battery storage capacity.

Battery storage systems are increasingly installed with wind and solar power projects. Wind and solar are intermittent sources of generation; they only produce electricity when the wind is blowing or the sun is shining. Batteries can store excess electricity from wind and solar generators for later use. In 2023, we expect 71% of the new battery storage capacity will be in California and Texas, states with significant solar and wind capacity.

Natural gas

Developers plan to build 7.5 GW of new natural-gas fired capacity record natural gas output in 2023, 83% of which is from combined-cycle plants. The two largest natural gas plants expected to come online in 2023 are the 1,836 megawatt (MW) Guernsey Power Station in Ohio and the 1,214 MW CPV Three Rivers Energy Center in Illinois.

Wind

In 2023, developers plan to add 6.0 GW of utility-scale wind capacity, as renewables poised to eclipse coal in global power generation. Annual U.S. wind capacity additions have begun to slow, following record additions of more than 14 GW in both 2020 and 2021.

The most wind capacity will be added in Texas in 2023, at 2.0 GW. The only offshore wind capacity expected to come online this year is a 130.0 MW offshore windfarm in New York called South Fork Wind.

Nuclear

Two new nuclear reactors at the Vogtle nuclear power plant in Georgia nuclear and net-zero are scheduled to come online in 2023, several years later than originally planned. The reactors, with a combined 2.2 GW of capacity, are the first new nuclear units built in the United States in more than 30 years.

Developers and power plant owners report planned additions to us in our annual and monthly electric generator surveys. In the annual survey, we ask respondents to provide planned online dates for generators coming online in the next five years. The monthly survey tracks the status of generators coming online based on reported in-service dates.

IEA World Energy Outlook 2020 highlights solar power as the cheapest electricity, projects faster renewables growth, models net-zero pathways, assesses COVID-19 impacts, oil and gas demand, and policy scenarios including STEPS, SDS, and NZE2050.

Key Points

A flagship IEA report analyzing energy trends, COVID-19 impacts, renewables growth, and pathways to net-zero in 2050.

✅ Solar now the cheapest electricity in most major markets

✅ Scenarios: STEPS, SDS, NZE2050, plus delayed recovery case

✅ Oil and gas demand uncertain; CO2 peak needs stronger policy

The world’s best solar power schemes now offer the “cheapest…electricity in history” with the technology cheaper than coal and gas in most major countries.

That is according to the International Energy Agency’s World Energy Outlook 2020. The 464-page outlook, published today by the IEA, also outlines the “extraordinarily turbulent” impact of coronavirus and the “highly uncertain” future of global energy use and progress in the global energy transition over the next two decades.

Reflecting this uncertainty, this year’s version of the highly influential annual outlook offers four “pathways” to 2040, all of which see a major rise in renewables across markets. The IEA’s main scenario has 43% more solar output by 2040 than it expected in 2018, partly due to detailed new analysis showing that solar power is 20-50% cheaper than thought.

Despite a more rapid rise for renewables and a “structural” decline for coal, the IEA says it is too soon to declare a peak in global oil use, unless there is stronger climate action. Similarly, it says demand for gas could rise 30% by 2040, unless the policy response to global warming steps up.

This means that, while global CO2 emissions have effectively peaked flatlining in 2019 according to the IEA, they are “far from the immediate peak and decline” needed to stabilise the climate. The IEA says achieving net-zero emissions will require “unprecedented” efforts from every part of the global economy, not just the power sector.

For the first time, the IEA includes detailed modeling of a 1.5C pathway that reaches global net-zero CO2 emissions by 2050. It says individual behaviour change, such as working from home “three days a week”, would play an “essential” role in reaching this new “net-zero emissions by 2050 case” (NZE2050).

Future scenarios
The IEA’s annual World Energy Outlook (WEO) arrives every autumn and contains some of the most detailed and heavily scrutinised analysis of the global energy system. Over hundreds of densely packed pages, it draws on thousands of datapoints and the IEA’s World Energy Model.

The outlook includes several different scenarios, to reflect uncertainty over the many decisions that will affect the future path of the global economy, as well as the route taken out of the coronavirus crisis during the “critical” next decade. The WEO also aims to inform policymakers by showing how their plans would need to change if they want to shift onto a more sustainable path, including creating the right clean electricity investment incentives to accelerate progress.

This year it omits the “current policies scenario” (CPS), which usually “provides a baseline…by outlining a future in which no new policies are added to those already in place”. This is because “[i]t is difficult to imagine this ‘business as-usual’ approach prevailing in today’s circumstances”.

Those circumstances are the unprecedented fallout from the coronavirus pandemic, which remains highly uncertain as to its depth and duration. The crisis is expected to cause a dramatic decline in global energy demand in 2020, with oil demand also dropping sharply as fossil fuels took the biggest hit.

The main WEO pathway is again the “stated policies scenario” (STEPS, formerly NPS). This shows the impact of government pledges to go beyond the current policy baseline. Crucially, however, the IEA makes its own assessment of whether governments are credibly following through on their targets.

The report explains:

“The STEPS is designed to take a detailed and dispassionate look at the policies that are either in place or announced in different parts of the energy sector. It takes into account long-term energy and climate targets only to the extent that they are backed up by specific policies and measures. In doing so, it holds up a mirror to the plans of today’s policy makers and illustrates their consequences, without second-guessing how these plans might change in future.”

The outlook then shows how plans would need to change to plot a more sustainable path, highlighting efforts to replace fossil fuels with electricity in time to meet climate goals. It says its “sustainable development scenario” (SDS) is “fully aligned” with the Paris target of holding warming “well-below 2C…and pursuing efforts to limit [it] to 1.5C”. (This interpretation is disputed.)

The SDS sees CO2 emissions reach net-zero by 2070 and gives a 50% chance of holding warming to 1.65C, with the potential to stay below 1.5C if negative emissions are used at scale.

The IEA has not previously set out a detailed pathway to staying below 1.5C with 50% probability, with last year’s outlook only offering background analysis and some broad paragraphs of narrative.

For the first time this year, the WEO has “detailed modelling” of a “net-zero emissions by 2050 case” (NZE2050). This shows what would need to happen for CO2 emissions to fall to 45% below 2010 levels by 2030 on the way to net-zero by 2050, with a 50% chance of meeting the 1.5C limit, with countries such as Canada's net-zero electricity needs in focus to get there.

The final pathway in this year’s outlook is a “delayed recovery scenario” (DRS), which shows what might happen if the coronavirus pandemic lingers and the global economy takes longer to recover, with knock-on reductions in the growth of GDP and energy demand.
