Aboitiz receives another award for financing for its Tiwi and Makban geothermal plant

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.

Canada Green Investment Gap highlights lagging EV and clean energy funding as peers surge. With a green recovery budget pending, sustainable finance, green bonds, EV charging, hydrogen, and carbon capture are pivotal to decarbonization.

Key Points

Canada lags peers in EV and clean energy investment, urging faster budget and policy action to cut emissions.

✅ Per capita climate spend trails US and EU benchmarks

✅ EVs, hydrogen, charging need scaled funding now

✅ Strengthen sustainable finance, green bonds, disclosure

Canada is being outpaced on the international stage when it comes to green investments in electric vehicles and green energy solutions, environmental groups say.

The federal government has an opportunity to change course in about three weeks, when the Liberals table their first budget in over two years, the International Institute for Sustainable Development (IISD) argued in a new analysis endorsed by nine other climate action, ecology and conservation organizations.

“Canada’s international peers are ramping up commitments for green recovery, including significant investments from many European countries,” states the analysis, “Investing for Tomorrow, Today,” published March 29.

“To keep up with our global peers, sufficient investments and strengthened regulations, including EV sales regulations, must work in tandem to rapidly decarbonize all sectors of the Canadian economy.”

Deputy Prime Minister and Finance Minister Chrystia Freeland confirmed last week that the federal budget will be tabled April 19. The Liberals are expected to propose between $70 billion and $100 billion in fiscal stimulus to jolt the economy out of its pandemic doldrums.

The government teased a coming economic “green transformation” late last year when Freeland released the fall economic statement, promising to examine federal green bonds, border carbon adjustments and a sustainable finance market, with tweaks like tightening the climate-risk disclosure obligations of corporations.

The government has also proposed a wide range of green measures in its new climate plan released in December — which the think tank called the “most ambitious” in Canada’s history — including energy retrofit programs, boosting hydrogen and other alternative fuels, and rolling out carbon capture technology in a grid where 18% of electricity still came from fossil fuels in 2019.

But the possible “three-year stimulus package to jumpstart our recovery” mentioned in the fall economic statement came with the caveat that the COVID-19 virus would have to be “under control.” While vaccines are being administered, Canada is currently dealing with a rise of highly transmissible variants of the virus.

Freeland spoke with United States Vice-President Kamala Harris on March 25, highlighting potential Canada-U.S. collaboration on EVs alongside the “need to support entrepreneurs, small businesses, young people, low-wage and racialized workers, the care economy, and women” in the context of an economic recovery.

Biden is contemplating a climate recovery plan that could exceed US$2 trillion as Canada looks to capitalize on the U.S. auto pivot to EVs to spur domestic industry. Per capita, that is over 8 times what Canada has announced so far for climate-related spending in the wake of the pandemic, according to a new analysis from green groups.
U.S. President Joe Biden is contemplating a climate and clean energy recovery plan that could “exceed US$2 trillion,” White House officials told reporters this month. “Per capita, that is over eight times what Canada has announced so far for climate-related spending in the wake of the pandemic,” the IISD-led analysis stated.

Biden’s election platform commitment of $508 billion over 10 years in clean energy was also seen as “significantly higher per capita than Canada’s recent commitments.”

Since October 2020, Canada has announced $36 billion in new climate-focused funding, a 2035 EV mandate and other measures, the groups found. By comparison, they noted, a political agreement in Europe proposed that a minimum of 37 per cent of investments in each national recovery plan should support climate action. France and Germany have also committed tens of billions of dollars to support clean hydrogen.

As for electric vehicles (EVs), the United Kingdom has committed $4.9 billion, while Germany has put up $7.5 billion to expand EV adoption and charging infrastructure and sweeten incentive programs for prospective buyers, complementing Canada’s ambitious EV goals announced domestically. The U.K. has also committed $3.5 billion for bike lanes and other active transportation, the groups noted.

Canada announced $400 million over five years this month for a new network of bike lanes, paths, trails and bridges, the first federal fund dedicated to active transportation.

Vineyard Wind Offshore Wind Farm delivers clean power to Massachusetts near Martha's Vineyard, with 62 turbines and 800 MW capacity, advancing renewable energy, cutting carbon, lowering costs, and driving net-zero emissions and green jobs.

Key Points

An 800 MW Massachusetts offshore project of 62 turbines supplying clean power to 400,000+ homes and cutting emissions.

✅ 800 MW powering 400,000+ MA homes and businesses

✅ 62 turbines, 13 MW each, 15 miles from Martha's Vineyard

✅ Cuts 1.6M tons CO2 annually; boosts jobs and port infrastructure

The crisp Atlantic air off the coast of Martha's Vineyard carried a new melody on February 2nd, 2024. Five colossal turbines, each taller than the Statue of Liberty, began their graceful rotations, marking the historic moment power began flowing from Vineyard Wind, the first large-scale offshore wind farm in the United States, enabled by Interior Department approval earlier in the project timeline. This momentous occasion signifies a seismic shift in Massachusetts' energy landscape, one that promises cleaner air, lower energy costs, and a more sustainable future for generations to come.

Nestled 15 miles southeast of Martha's Vineyard and Nantucket, Vineyard Wind is a colossal undertaking. The project, a joint venture between Avangrid Renewables and Copenhagen Infrastructure Partners, will ultimately encompass 62 turbines, each capable of generating a staggering 13 megawatts. Upon full completion later this year, Vineyard Wind will power over 400,000 homes and businesses across Massachusetts, contributing a remarkable 800 megawatts to the state's energy grid.

But the impact of Vineyard Wind extends far beyond mere numbers. This trailblazing project holds immense environmental significance. By harnessing the clean and inexhaustible power of the wind, Vineyard Wind is projected to annually reduce carbon emissions by a staggering 1.6 million metric tons – equivalent to taking 325,000 cars off the road. This translates to cleaner air, improved public health, and a crucial step towards mitigating the climate crisis.

Governor Maura Healey hailed the project as a "turning point" in Massachusetts' clean energy journey. "Across the Commonwealth, homes and businesses will now be powered by clean, affordable energy, contributing to cleaner air, lower energy costs, and pushing us closer to achieving net-zero emissions," she declared.

Vineyard Wind's impact isn't limited to the environment; it's also creating a wave of economic opportunity. Since its inception in 2017, the project has generated nearly 2,000 jobs, with close to 1,000 positions filled by union workers thanks to a dedicated Project Labor Agreement. Construction has also breathed new life into the New Bedford Marine Commerce Terminal, with South Coast construction activity accelerating around the port, transforming it into the nation's first port facility specifically designed for offshore wind, showcasing the project's commitment to local infrastructure development.

"Every milestone on Vineyard Wind 1 is special, but powering up these first turbines stands apart," emphasized Pedro Azagra, CEO of Avangrid Renewables. "This accomplishment reflects the years of dedication and collaboration that have defined this pioneering project. Each blade rotation and megawatt flowing to Massachusetts homes is a testament to the collective effort that brought offshore wind power to the United States."

Vineyard Wind isn't just a project; it's a catalyst for change. It perfectly aligns with Massachusetts' ambitious clean energy goals, which include achieving net-zero emissions by 2050 and procuring 3,200 megawatts of offshore wind by 2028, while BOEM lease requests in the Northeast continue to expand the development pipeline across the region. As Energy and Environmental Affairs Secretary Rebecca Tepper stated, "Standing up a new industry is no easy feat, but we're committed to forging ahead and growing this sector to lower energy costs, create good jobs, and build a cleaner, healthier Commonwealth."

The launch of Vineyard Wind transcends Massachusetts, serving as a beacon for the entire U.S. offshore wind industry, as New York's biggest offshore wind farm moves forward to amplify regional momentum. This demonstration of large-scale development paves the way for further investment and growth in this critical clean energy source. However, the journey isn't without its challenges, and questions persist about reaching 1 GW on the grid nationwide as stakeholders navigate timelines. Concerns regarding potential impacts on marine life and visual aesthetics remain, requiring careful consideration and ongoing community engagement.

Despite these challenges, Vineyard Wind stands as a powerful symbol of hope and progress. It represents a significant step towards a cleaner, more sustainable future, powered by renewable energy sources at a time when U.S. offshore wind is about to soar according to industry outlooks. It's a testament to the collaborative effort of policymakers, businesses, and communities working together to tackle the climate crisis. As the turbines continue their majestic rotations, they carry a message of hope, reminding us that a brighter, more sustainable future is within reach, powered by the wind of change.

Additional Considerations:

• The project boasts a dedicated Fisheries Innovation Fund, fostering collaboration between the fishing and offshore wind industries to ensure sustainable coexistence.
• Vineyard Wind has invested in education and training programs, preparing local residents for careers in the burgeoning wind energy sector.
• The project's success opens doors for further offshore wind development in the U.S., such as Long Island proposals gaining attention, paving the way for a clean energy revolution.

Canada Solar Capacity Outlook 2022-2050 projects 500 MW new PV in 2022 and 35 GW by 2050, driven by renewables policy, grid parity, NREL analysis, IEA-PVPS data, and competitive utility-scale photovoltaic costs.

Key Points

An evidence-based forecast of Canadian PV additions to 35 GW by 2050, reflecting policy, costs, and grid parity trends.

✅ 500 MW PV expected in 2022; cumulative capacity near 5 GW

✅ NREL outlook sees 35 GW by 2050 on cost competitiveness

✅ Policy shifts, ITCs, coal retirements accelerate solar uptake

Canada is set to install 500 MW of new solar in 2022, bringing its total capacity to about 5 GW, according to data from Canmet Energy, even as the Netherlands outpaces Canada in solar power generation. The country is expected to hit 35 GW of total solar capacity by 2050.

Canada’s cumulative solar capacity is set to hit 5 GW by the end of this year, according to figures from the federal government’s Canmet Energy lab. The country is expected to add around 500 MW of new solar capacity, from 944 MW last year, according to the International Energy Agency Photovoltaic Power Systems Programme (IEA-PVPS), which recently published a report on PV applications in Canada, even as solar demand lags in Canada.

“If we look at the recent averages, Canada has installed around 500 MW annually. I expect in 2022 it will be at least 500 MW,” said Yves Poissant, research manager at Canmet Energy. “Last year it was 944 MW, mainly because of a 465 MW centralized PV power plant installed in Alberta, where the Prairie Provinces are expected to lead national renewable growth.”

The US National Renewable Energy Laboratory (NREL) studied renewables integration and concluded that Canada’s cumulative solar capacity will increase sevenfold to 35 GW by 2050, driven by cost competitiveness and that zero-emissions by 2035 is achievable according to complementary studies.

Canada now produces 80% of its electricity from power sources other than oil. Hydroelectricity leads the mix at 60%, followed by nuclear at 15%, wind at 7%, gas and coal at 7%, and PV at just 1%. While the government aims to increase the share of green electricity to 90% by 2030 and 100% by 2050, zero-emission electricity by 2035 is considered practical and profitable, yet it has not set any specific goals for PV. Each Canadian province and territory is left to determine its own targets.

“Without comprehensive pan-Canadian policy framework with annual capacity targets, PV installation in the coming years will likely continue to be highly variable across the provinces and territories, especially after Ontario scrapped a clean energy program, which scaled back growth projections. Further policies mechanisms are needed to allow PV to reach its full potential,” the IEA-PVPS said.

Popular content
Canada recently introduced investment tax credits for renewables to compete with the United States, but it is still far from being a solar powerhouse, with some experts calling it a solar laggard today. That said, the landscape has started to change in the past five years.

“Some laws have been put in place to retire coal plants by 2025. That led to new opportunities to install capacity,” said Poissant. “We expect the newly installed capacity will consist mostly of wind, but also solar.”

The cost of solar has become more competitive and the residential sector is now close to grid parity, according to Poissant. For utility-scale projects, old hydroelectric dams are still considerably cheaper than solar, but newly built installations are now more expensive than solar.

“Starting 2030, solar PV will be cost competitive compared to wind,” Poissant said.

Tesla Battery Day Innovations detail larger cylindrical EV cells with higher energy density, greater power, longer range, cobalt-free chemistry, automated manufacturing, battery recycling, and lower cost per kWh to enable an affordable electric car.

Key Points

Tesla Battery Day innovations are new EV cells and methods to cut costs, extend range, and scale production.

✅ Larger cylindrical cells: 5x energy, 6x power, 16% more range

✅ Automation and recycling to cut battery cost per kWh

✅ Near-zero cobalt chemistry, in-house cell factories worldwide

Elon Musk described a new generation of electric vehicle batteries that will be more powerful, longer lasting, and half as expensive as the company’s current cells at Tesla’s “Battery Day”.

Tesla’s new larger cylindrical cells will provide five times more energy, six times more power and 16% greater driving range, Musk said, adding that full production is about three years away.

“We do not have an affordable car. That’s something we will have in the future. But we’ve got to get the cost of batteries down,” Musk said.

To help reduce cost, Musk said Tesla planned to recycle battery cells at its Nevada “gigafactory,” while reducing cobalt – one of the most expensive battery materials – to virtually zero. It also plans to manufacture its own battery cells at several highly automated factories around the world.

The automaker plans to produce the new cells via a highly automated, continuous-motion assembly process, according to Drew Baglino, Tesla senior vice-president of powertrain and energy engineering, a contrast with GM and Ford battery strategies in the broader market today.

Speaking at the event, during which Musk outlined plans to cut costs and reiterated a huge future for Tesla's energy business during the presentation, the CEO acknowledged that Tesla does not have its new battery design and manufacturing process fully complete.

The automaker’s shares slipped as Musk forecast the change could take three years. Tesla has frequently missed production targets.

Tesla expects to eventually be able to build as many as 20m electric vehicles a year, aligning with within-a-decade EV adoption outlooks cited by analysts. This year, the entire auto industry expects to deliver 80m cars globally.

At the opening of the event, which drew over 270,000 online viewers, Musk walked on stage as about 240 shareholders – each sitting in a Tesla Model 3 in the company parking lot – honked their car horns in approval.

As automakers shift from horsepower to kilowatts to comply with stricter environmental regulations amid an age of electric cars that appears ahead of schedule, investors are looking for evidence that Tesla can increase its lead in electrification technology over legacy automakers who generate most of their sales and profits from combustion-engine vehicles.

While average electric vehicle prices have decreased in recent years thanks to changes in battery composition and evidence that they are better for the planet and household budgets, they are still more expensive than conventional cars, with the battery estimated to make up a quarter to a third of an electric vehicle’s cost.

Some researchers estimate that price parity, or the point at which electric vehicles are equal in value to internal combustion cars, is reached when battery packs cost $100 per kilowatt hour (kWh), a potential inflection point for mass adoption.

Tesla’s battery packs cost $156 per kWh in 2019, according to electric vehicle consulting firm Cairn Energy Research Advisors, with some studies noting that EVs save money over time for consumers, which would put the cost of a 90-kWh pack at around $14,000.

Tesla is also building its own cell manufacturing facility at its new factory in Germany in addition to the new plant in Fremont.

Inflation Reduction Act Energy Credits help households electrify with tax credits and rebates for heat pumps, EVs, rooftop solar, battery storage, and efficiency upgrades, cutting utility bills, reducing carbon emissions, and accelerating home electrification nationwide.

Key Points

Federal incentives offering tax credits and rebates for heat pumps, EVs, solar, and efficiency to cut emissions.

✅ 30% rooftop solar and storage credit; $2,000 annual cap for heat pumps

✅ Up to $7,500 EV tax credit; price, income, and assembly rules apply

✅ Low-income rebates and discounts available via states starting mid-2023

Earlier this year, Congress passed the biggest climate bill in history — cloaked under the name the “Inflation Reduction Act,” a historic climate deal by any measure.

Starting in the new year, the bill will offer households thousands of dollars to transition over from fossil-fuel burning heaters, stoves and cars to cleaner versions as renewable electricity accelerates. On Jan. 1, middle-income households will be able to access over a half-dozen tax credits for electric stoves, cars, rooftop solar and more. And starting sometime in mid-2023, lower-income households will be able to get upfront discounts on some of those same appliances — without having to wait to file their taxes to get the cash back. This handy online tool shows what you might be eligible for, depending on your Zip code and income.

But which credits should Americans focus on — and which are best for the climate? Here’s a guide to the top climate-friendly benefits of the Inflation Reduction Act, and how to access them.

Heat pumps — the best choice for decarbonizing at home

Tax credit available on Jan. 1: 30 percent of the cost, up to $2,000

Income limit: None

Ah, heat pumps — one of the most popular technologies of the transition to clean energy and to net-zero electricity systems. “Heat pump” is a bit of a misnomer for these machines, which are more like super-efficient combo air conditioning and heating systems. These appliances run on electricity and move heat, instead of creating it, and so can be three to five times more efficient than traditional gas or electrical resistance heaters.

“For a lot of people, a heat pump is going to be their biggest personal impact,” said Sage Briscoe, the federal senior policy manager at Rewiring America, a clean-energy think tank. (Heat pumps have become so iconic that Rewiring America even has a heat pump mascot.)

Heat pumps can have enormous cost and carbon savings. According to one analysis using data from the National Renewable Energy Laboratory, switching to a heat pump can save homeowners anywhere from $100 to $1,200 per year on heating bills and prevent anywhere from 1 to 8 metric tons of carbon dioxide emissions per year. For comparison, going vegan for an entire year saves about 1 metric ton of CO2 emissions.

But many consumers encounter obstacles when switching over to heat pumps. In some areas, it can be difficult to find a contractor trained and willing to install them; some homeowners report that contractors share misinformation about heat pumps, including that they don’t work in cold climates. (Modern heat pumps do work in cold climates, and can heat a home even when outdoor temperatures are down to minus-31 degrees Fahrenheit.) Briscoe recommends that homeowners look for skilled contractors who know about heat pumps and do advance research to figure out which models might work best for their home.

Electric vehicles — top choice for cutting car emissions

Tax credit available on Jan. 1: Up to $7,500 depending on the make and model of the car

Income limit: <$150,000 for single filers; <$300,000 for joint filers

If you are like the millions of Americans who don’t live in a community with ample public transit, the best way to decarbonize your transport, as New Zealand's electricity transition shows, is switching to an electric car. But electric cars can be prohibitively expensive for many Americans.

Starting Jan. 1, a new EV tax credit will offer consumers up to $7,500 off the purchase of an electric vehicle. For the first few months, Americans will get somewhere between $3,751 and $7,500 off their purchase of an EV, depending on the size of the battery in the car.

There are limitations, per the new law. The vehicles will also have to be assembled in North America, where Canada's electricity progress is notable, and cars that cost more than $55,000 aren’t eligible, nor are vans or trucks that cost more than $80,000. This week, the Internal Revenue Service provided a list of vehicles that are expected to meet the criteria starting Jan. 1.

Beginning about March, however, that $7,500 credit will be split into two parts: Consumers can get a $3,750 credit if the vehicle has a battery containing at least 40 percent critical minerals from the United States (or a country that the United States has a free-trade agreement with) and another $3,750 credit if at least 50 percent of the battery’s components were assembled and manufactured in North America. Those rules haven’t been finalized yet, so the tax credit starting on Jan. 1 is a stopgap measure until the White House has ironed out the final version.

Joe Britton, the executive director of the EV industry group Zeta, said that means there will likely be a wider group of vehicles eligible for the full tax credit in January and February than there will be later in 2023. Because of this, he recommended that potential EV owners act fast in 2023.

“I would be buying a car in the first quarter,” he said.

Rooftop solar — the best choice for generating clean energy

Tax credit available now: 30 percent of the cost of installation, no cap

Income limit: None

For those who want to generate their own clean energy, there is always rooftop solar panels. This tax credit has actually been available since the Inflation Reduction Act was signed into law in August 2022. It offers a tax credit equal to 30 percent of the cost of installing rooftop solar, with no cap. According to Rewiring America, the average 6 kilowatt solar installation costs about $19,000, making the average solar tax credit about $5,700. (The Inflation Reduction Act also includes a 30 percent tax credit for homeowners that need to upgrade their electricity panel for rooftop solar, and a 30 percent tax credit for installing battery storage to support the shift toward carbon-free electricity solutions.)

Solar panels can save homeowners tens of thousands of dollars in utility bills as extreme heat boosts electricity bills and, when combined with battery storage, can also provide a power backup in the case of a blackout or other disaster. For someone trying to move their entire home away from fossil fuels, solar panels become even more enticing: Switch everything over to electricity, and then make the electricity super cheap with the help from the sun.

For people who don’t own their own homes, there are other options as well. Renters can subscribe to a community solar project to lower their electricity bills and get indirect benefits from the tax credits.
