Nova Scotia Power increases use of biomass for generating electricity

2020 U.S. Renewable Electricity Generation set a record as wind, solar, hydro, biomass, and geothermal produced 834 billion kWh, surpassing coal and nuclear, second only to natural gas in nationwide power output.

Key Points

The record year when renewables made 834 billion kWh, topping coal and nuclear in U.S. electricity.

✅ Renewables supplied 21% of U.S. electricity in 2020

✅ Coal output fell 20% y/y; nuclear slipped 2% on retirements

✅ EIA forecasts renewables rise in 2021-2022; coal rebounds

In 2020, renewable energy sources (including wind, hydroelectric, solar, biomass, and geothermal energy) generated a record 834 billion kilowatthours (kWh) of electricity, or about 21% of all the electricity generated in the United States. Only natural gas (1,617 billion kWh) produced more electricity than renewables in the United States in 2020. Renewables surpassed both nuclear (790 billion kWh) and coal (774 billion kWh) for the first time on record. This outcome in 2020 was due mostly to significantly less coal use in U.S. electricity generation and steadily increased use of wind and solar generation over time, amid declining consumption trends nationwide.

In 2020, U.S. electricity generation from coal in all sectors declined 20% from 2019, while renewables, including small-scale solar, increased 9%. Wind, currently the most prevalent source of renewable electricity in the United States, grew 14% in 2020 from 2019, and the EIA expects solar and wind to be larger sources in summer 2022, reflecting continued growth. Utility-scale solar generation (from projects greater than 1 megawatt) increased 26%, and small-scale solar, such as grid-connected rooftop solar panels, increased 19%, while early 2021 January power generation jumped year over year.

Coal-fired electricity generation in the United States peaked at 2,016 billion kWh in 2007 and much of that capacity has been replaced by or converted to natural gas-fired generation since then. Coal was the largest source of electricity in the United States until 2016, and 2020 was the first year that more electricity was generated by renewables and by nuclear power than by coal (according to our data series that dates back to 1949). Nuclear electric power declined 2% from 2019 to 2020 because several nuclear power plants retired and other nuclear plants experienced slightly more maintenance-related outages.

We expect coal-fired generation to increase in the United States during 2021 as natural gas prices continue to rise and as coal becomes more economically competitive. Based on forecasts in our Short-Term Energy Outlook (STEO), we expect coal-fired electricity generation in all sectors in 2021 to increase 18% from 2020 levels before falling 2% in 2022. We expect U.S. renewable generation across all sectors to increase 7% in 2021 and 10% in 2022, and in 2021, non-fossil fuel sources accounted for about 40% of U.S. electricity. As a result, we forecast coal will be the second-most prevalent electricity source in 2021, and renewables will be the second-most prevalent source in 2022. We expect nuclear electric power to decline 2% in 2021 and 3% in 2022 as operators retire several generators.

Germany is extending its vehicle tax exemption for electric cars until 2035, a federal move aimed at boosting EV sales, supporting the auto industry, and advancing the country’s transition to cleaner, more sustainable transportation.

Why is Germany Exempting EVs from Vehicle Tax Until 2035?

Germany is exempting electric vehicles from vehicle tax until 2035 to boost EV adoption, support its auto industry, and meet national climate targets.

✅ Encourages consumers to buy zero-emission cars

✅ Protects jobs in the automotive sector

✅ Advances Germany’s clean energy transition

Germany’s federal government has confirmed plans to extend the country’s vehicle tax exemption for electric cars until 2035, as part of a renewed push to accelerate the nation’s e-mobility transition and support its struggling automotive industry. The move, announced by Finance Minister Lars Klingbeil, comes just weeks before the existing exemption was set to expire.

“In order to get many more electric cars on the road in the coming years, we need to provide the right incentives now,” Klingbeil told the German Press Agency (DPA). “That is why we will continue to exempt electric cars from vehicle tax.”

Under the proposed law, the exemption will apply to new fully electric vehicles registered until December 31, 2030, with benefits lasting until the end of 2035. According to the Finance Ministry, the measure aims to “provide an incentive for the early purchase of a purely electric vehicle.” While popular among consumers and automakers, the plan is expected to cost the federal budget several hundred million euros in lost revenue.

Without the extension, the tax relief for new battery-electric vehicles (BEVs) would have ended on January 1, 2026, creating uncertainty for automakers and potential buyers. The urgency to pass the new legislation reflects the government’s goal to maintain Germany’s momentum toward electrification, even as the age of electric cars accelerates amid economic headwinds and fierce international competition.

The exemption’s renewal was originally included in the coalition agreement between the Christian Democratic Union (CDU), the Christian Social Union (CSU), and the Social Democratic Party (SPD). It follows two other measures from the government’s “investment booster” package—raising the maximum gross price for EV tax incentives to €100,000 and allowing special depreciation for electric vehicles. However, the vehicle tax measure was previously in jeopardy due to Germany’s tight fiscal situation. The Finance Ministry had cautioned that every proposal in the coalition deal was “subject to financing,” and a plan to end EV subsidies led to speculation that the EV tax break could be dropped altogether.

Klingbeil’s announcement coincides with an upcoming “automotive dialogue” summit at the Chancellery, hosted by Chancellor Friedrich Merz. The meeting will bring together representatives from federal ministries, regional governments, automakers advancing initiatives such as Daimler’s electrification plan across their portfolios, and trade unions to address both domestic and international challenges facing Germany’s car industry. Topics will include slowing EV sales growth in China, the ongoing tariff dispute with the United States, where EPA emissions rules are expected to boost EV sales, and strategies for strengthening Germany’s global competitiveness.

“We must now put together a strong package to lead the German automotive industry into the future and secure jobs,” Klingbeil said. “We want the best cars to continue to be built in Germany. Everyone knows that the future is electric.”

The government is also expected to revisit a proposed program to help low- and middle-income households access electric cars, addressing affordability concerns that persist across markets, modelled on France’s “social leasing” initiative. Though included in the coalition agreement, progress on that program has stalled, and few details have emerged since its announcement.

Germany’s latest tax policy move signals renewed confidence in its electric vehicle transition, despite budget constraints and a turbulent global market, as the 10-year EV outlook points to most cars being electric worldwide. Extending the exemption until 2035 sends a clear message to consumers and manufacturers alike: the country remains committed to building its clean transport future—one electric car at a time.

Eastern Green Link 1 is a 190km HVDC subsea electricity superhighway linking Scotland to northern England, delivering renewable energy, boosting grid capacity, and enhancing energy security for National Grid and Scottish Power.

Key Points

A 190km HVDC subsea link sending Scottish renewables to northern England, boosting grid capacity and UK energy security.

✅ 190km HVDC subsea route from East Lothian to County Durham

✅ Cables by Prysmian; converter stations by GE Vernova, Mytilineos

✅ Powers the equivalent of 2 million UK households

One of Britain’s biggest power grid projects has awarded contracts worth £1.8bn for a 190km subsea electricity superhighway, akin to a hydropower line to New York in scale, to bring renewable power from Scotland to the north of England.

National Grid and Scottish Power, following a recent 2GW substation commissioning, plan to begin building the “transformative” £2.5bn high-voltage power line along the east coast of the country from East Lothian to County Durham from 2025.

The Eastern Green Link 1 (EGL1) project is one of Britain’s largest grid upgrade projects in generations and has been designed to carry enough clean electricity to power the equivalent of 2 million households.

The UK is under pressure to deliver a power grid overhaul, including moves to fast-track grid connections nationwide, as it prepares to double its demand for electricity by 2040 as part of a plan to cut the use of gas and other fossil fuels.

The International Energy Agency has forecast that 600,000km of electric lines will need to be either added or upgraded across the UK by the end of the next decade to meet its climate targets, amid a global race to secure supplies of high voltage cabling and other electrical infrastructure components and to explore superconducting cables to cut losses.

The EGL1 project has awarded Prysmian Group, an international cable maker, the contract to deliver nearly 400km of power cable. The contract to supply two HVDC technology converter stations, one at each end of the cable, has been awarded to GE Vernova and Mytilineos.

The upgrades are expected to cost tens of billions of pounds, according to National Grid, which faces plans for an independent system operator overseeing Great Britain’s electricity market. The FTSE 100 energy company has warned that five times as many pylons and underground lines need to be constructed by the end of the decade than in the past 30 years, and four times more undersea cables laid than there are at present.

Britain’s power grid upgrades are also expected to emerge as an important battleground in the general election. The next government will need to balance the strong local opposition to new grid infrastructure across rural areas of the UK against the climate and economic benefits of the work.

Research undertaken by National Grid has found there will be an estimated 400,000 jobs created by 2050 due to the work needed to rewire Britain’s grid, a trend mirrored by recent cross-border transmission approvals in North America, including about 150,000 jobs anticipated in Scotland and the north of England.

Peter Roper, the project director for EGL1, said the super-cable would be “a transformative project for the UK, enhancing security of supply and helping to connect and transport green power for all customers”.

He added: “These contract announcements are big wins for the supply chain and another important milestone as we build the new network infrastructure to help the UK meet its net zero and energy security ambitions.

GM Canada-Unifor EV Deal outlines a $1B plan to transform the CAMI plant in Ingersoll, Ontario, building BrightDrop EV600 delivery vans, boosting EV manufacturing, creating jobs, and securing future production with government-backed investment.

Key Points

A tentative $1B deal to retool CAMI for BrightDrop EV600 production, creating jobs and securing Canada's EV manufacturing.

✅ $1B to transform CAMI, Ingersoll, for BrightDrop EV600 vans

✅ Ratification vote set; Unifor Local 88 to review details

✅ Supports EV manufacturing, delivery logistics, and new jobs

GM Canada says it has reached a tentative deal with Unifor that if ratified will see it invest $1 billion to transform its CAMI plant in Ingersoll, Ont., to make commercial electric vehicles, aligning with GM's EV hiring plans across North America.

Unifor National President Jerry Dias says along with the significant investment the agreement will mean new products, new jobs amid Ontario's EV jobs boom and job security for workers.

Dias says in a statement that more details of the tentative deal will be presented to Unifor Local 88 members at an online ratification meeting scheduled for Sunday.

He says the results of the ratification vote are scheduled to be released on Monday.

Details of the agreement were not released Friday night.

A GM spokeswoman says in a statement that the plan is to build BrightDrop EV 600s -- an all-new GM business announced this week at the Consumer Electronics Show and part of EV assembly deals that put Canada in the race -- that will offer a cleaner way for delivery and logistics companies to move goods more efficiently.

Unifor said the contract, if ratified, will bring total investment negotiated by the union to nearly $6 billion after new agreements were ratified with General Motors, Ford, including Ford EV production plans, and Fiat Chrysler in 2020 that included support from the federal and Ontario governments, and parallel investments such as a Niagara Region battery plant bolstering the supply chain.

It said the Ford deal reached in September included $1.95 billion to bring battery electric vehicle production to Oakville via the Oakville EV deal and a new engine derivative to Windsor and the Fiat Chrysler agreement included more than $1.5 billion to build plug-in hybrid vehicles and battery electric vehicles.

Unifor said in November, General Motors agreed to a $1.3 billion dollar investment to bring 1,700 jobs to Oshawa, as Honda's Ontario battery investment signals wider sector momentum, plus more than $109 million to in-source new transmission work for the Corvette and support continued V8 engine production in St. Catharines.

Vehicle-to-Home (V2H) Power enables EVs to act as backup generators and home batteries, using bidirectional charging, inverters, and rooftop solar to cut energy costs, stabilize the grid, and provide resilient, outage-proof electricity.

Key Points

Vehicle-to-Home (V2H) Power lets EV batteries run household circuits via bidirectional charging and an inverter.

✅ Cuts energy bills using solar, time-of-use rates, and storage

✅ Provides resilient backup during outages, storms, and blackouts

✅ Enables grid services via V2G/V2H with smart chargers

When the power went out at Nate Graham’s New Mexico home last year, his family huddled around a fireplace in the cold and dark. Even the gas furnace was out, with no electricity for the fan. After failing to coax enough heat from the wood-burning fireplace, Graham’s wife and two children decamped for the comfort of a relative’s house until electricity returned two days later.

The next time the power failed, Graham was prepared. He had a power strip and a $150 inverter, a device that converts direct current from batteries into the alternating current needed to run appliances, hooked up to his new Chevy Bolt, an electric vehicle. The Bolt’s battery powered his refrigerator, lights and other crucial devices with ease. As the rest of his neighborhood outside Albuquerque languished in darkness, Graham’s family life continued virtually unchanged. “It was a complete game changer making power outages a nonissue,” says Graham, 35, a manager at a software company. “It lasted a day-and-a-half, but it could have gone much longer.”

Today, Graham primarily powers his home appliances with rooftop solar panels and, when the power goes out, his Chevy Bolt. He has cut his monthly energy bill from about $220 to $8 per month. “I’m not a rich person, but it was relatively easy,” says Graham “You wind up in a magical position with no [natural] gas, no oil and no gasoline bill.”

Graham is a preview of what some automakers are now promising anyone with an EV: An enormous home battery on wheels that can reverse the flow of electricity to power the entire home through the main electric panel.

Beyond serving as an emissions-free backup generator, the EV has the potential of revolutionizing the car’s role in American society, with California grid programs piloting vehicle-to-grid uses, transforming it from an enabler of a carbon-intensive existence into a key step in the nation’s transition into renewable energy.

Home solar panels had already been chipping away at the United States’ centralized power system, forcing utilities to make electricity transfer a two-way street. More recently, home batteries have allowed households with solar arrays to become energy traders, recharging when electricity prices are low, replacing grid power when prices are high, and then sell electricity back to the grid for a profit during peak hours.

But batteries are expensive. Using EVs makes this kind of home setup cheaper and a real possibility for more Americans as the American EV boom accelerates nationwide.

So there may be a time, perhaps soon, when your car not only gets you from point A to point B, but also serves as the hub of your personal power plant.

I looked into new vehicles and hardware to answer the most common questions about how to power your home (and the grid) with your car.

Why power your home with an EV battery

America’s grid is not in good shape. Prices are up and reliability is down, and many state power grids face new challenges from rising EV adoption. Since 2000, the number of major outages has risen from less than two dozen to more than 180 per year, based on federal data, the Wall Street Journal reports. The average utility customer in 2020 endured about eight hours of power interruptions, double the previous decade.

Utilities’ relationship with their customers is set to get even rockier. Residential electricity prices, which have risen 21 percent since 2008, are predicted to keep climbing as utilities spend more than $1 trillion upgrading infrastructure, erecting transmission lines for renewable energy and protecting against extreme weather, even though grids can handle EV loads with proper management and planning.

U.S. homeowners, increasingly, are opting out. About 8 percent of them have installed solar panels. An increasing number are adding home batteries from companies such as LG, Tesla and Panasonic. These are essentially banks of battery cells, similar to those in your laptop, capable of storing energy and discharging electricity.

EnergySage, a renewable energy marketplace, says two-thirds of its customers now request battery quotes when soliciting bids for home solar panels, and about 15 percent install them. This setup allows homeowners to declare (at least partial) independence from the grid by storing and consuming solar power overnight, as well as supplying electricity during outages.

But it doesn’t come cheap. The average home consumes about 20 kilowatt-hours per day, a measure of energy over time. That works out to about $15,000 for enough batteries on your wall to ensure a full day of backup power (although the net cost is lower after incentives and other potential savings).

How an EV battery can power your home

Ford changed how customers saw their trucks when it rolled out a hybrid version of the F-150, says Ryan O’Gorman of Ford’s energy services program. The truck doubles as a generator sporting as many as 11 outlets spread around the vehicle, including a 240-volt outlet typically used for appliances like clothes dryers. During disasters like the 2021 ice storm that left millions of Texans without electricity, Ford dealers lent out their hybrid F-150s as home generators, showing how mobile energy storage can bring new flexibility during outages.

The Lightning, the fully electric version of the F-150, takes the next step by offering home backup power. Under each Lightning sits a massive 98 kWh to 131 kWh battery pack. That’s enough energy, Ford estimates, to power a home for three days (10 days if rationing). “The vehicle has an immense amount of power to move that much metal down the road at 80 mph,” says O’Gorman.

US Renewable Energy Growth drives the US electricity mix as wind, solar, and hydropower rise while coal, natural gas, and nuclear decline, boosting market share month over month and year over year across the grid.

Key Points

US Renewable Energy Growth tracks rising wind, solar, and hydro shares in the mix as coal, gas, and nuclear decline.

✅ Wind and solar surpass nuclear in April share

✅ Renewables reach 29.3% of US electricity in April

✅ Coal and natural gas shares trend lower since 2020

Electricity generated by renewable energy sources continues to grow month over month and year over year in the United States. In April 2022, the share of US electricity coming from renewable energy was up to 29.3%, surpassing a record April level reported previously in national data. That was up from 24.8% in April 2020 and 25.7% in April 2021.

Looking at the first four months of the year, renewables provided 25.5% of US electricity, and were the second-most U.S. source in 2020 as well, while the figure for January–April 2020 was 21.7% and the figure for January–April 2021 was 22.5%.

Coal power (20.2% of US electricity) was down year over year in this time period (from 22% in January–April 2021), even as renewables surpassed coal in 2022 nationwide, but is admittedly still a bit higher than it was in January–April 2020 (16.8%).

Electricity from natural gas is also down year over year, but only very slightly (34.7% for both years). Though, it has dropped significantly since January–April 2020 (39.6%).

Electricity from nuclear power continued to take a steady, step-by-step tumble.

Wind & Solar Power Growth Strong
As reported earlier, April was the first month that wind and solar power provided more electricity than nuclear across the United States. Wind and solar power provided 21% of US electricity, while nuclear power provided 17.8% of US electricity (coal, incidentally, also provided 17.8% of US electricity, but wind and solar had provided more electricity than coal in some previous months as well).

Wind and solar power’s combined market share for the first four months of the year was up from just 14.6% in 2020 and 18.4% in 2021.

Looking at their growth year over year, you can see strong and continuous expansion of solar-provided electricity and wind-provided electricity, amid favorable government plans that have supported deployment.

Solar grew from 2.9% in January–April 2020 to 3.6%in January–April 2021 to, eventually, 4.4% in January–April 2022, with solar's 2022 share rising to 4.7% for the full year. Wind rose from 9.2% to 10.3% to 12.2%.

Together, wind and solar were up from 12.1% in January–April 2020 to 13.9% in January–April 2021, reflecting a surge in wind power within the U.S. electricity mix over this period, to 16.7% January–April 2022.

Hydropower (6.5%) is holding approximately the same position as the same period in 2021 (6.5%), but it is down a significant chunk from April 2020 (8.2%).
