Wind has become the ‘most-used’ source of renewable electricity generation in the US

Rattlesnake Ridge Wind Project delivers 117.6 MW in southeast Alberta for BHE Canada, a Berkshire Hathaway Energy subsidiary, using 28 turbines near Medicine Hat under a long-term PPA, supplying renewable power to 79,000 homes.

Key Points

A 117.6 MW Alberta wind farm by BHE Canada supplying 79,000 homes via 28 turbines and a long-term PPA.

✅ 28 turbines near Medicine Hat, 117.6 MW capacity

✅ Long-term PPA with a major Canadian corporate buyer

✅ Developed with RES; no subsidies; competitive pricing

A company linked to U.S. investor Warren Buffett says it will break ground on a $200-million, 117.6-megawatt wind farm in southeastern Alberta next year.

In a release, Calgary-based BHE Canada, a subsidiary of Buffett's Berkshire Hathaway Energy, says its Rattlesnake Ridge Wind project will be located southwest of Medicine Hat and will produce enough energy to supply the equivalent of 79,000 homes.

"We felt that it was time to make an investment here in Alberta," said Bill Christensen, vice-president of corporate development for BHE Canada, in an interview with the Calgary Eyeopener.

"The structure of the markets here in Alberta, including frameworks for selling renewable energy, make it so that we can invest, and do it at a profit that works for us, and at a price that works for the off-taker," Christensen explained.

Berkshire Hathaway Energy also owns AltaLink, the regulated transmission company that supplies electricity to more than 85 per cent of the Alberta population.

BHE Canada says an unnamed large Canadian corporate partner has signed a long-term power purchase agreement, similar to RBC's solar purchase arrangements, for the majority of the energy output generated by the 28 turbines at Rattlesnake Ridge.

"If you look at just the raw power price that power is going for in Alberta right now, it's averaged around $55 a megawatt hour, or 5.5 cents a kilowatt hour. And we're selling the wind power to this customer at substantially less than that, reflecting wind power's competitiveness in the market, and there's been no subsidies," Christensen said.

Positive energy outlook

Christensen said he sees a good future for Alberta's renewable energy industry, not just in wind but also in solar power growth, particularly in the southeast of the province.

But he says BHE Canada is interested in making investments in traditional energy in Alberta, too, as the province is a powerhouse for both green energy and fossil fuels overall.

"It's not a choice of one or the other. I think there is still opportunity to make investments in oil and gas," he said.

"We're really excited about having this project and hope to be able to make other investments here in Alberta to help support the economy here, amid a broader renewable energy surge across the province."

The project is being developed by U.K.-based Renewable Energy Systems, part of a trend where more energy sources make better projects for developers, which is building two other Alberta wind projects totalling 134.6 MW this year and has 750 MW of renewable energy installed or currently under construction in Canada.

BHE Canada and RES are also looking for power purchase partners for the proposed Forty Mile Wind Farm in southeastern Alberta. They say that with generation capacity of 398.5 MW, it could end up being the largest wind power project in Canada.

US energy mix shows how the electric grid blends renewables, fossil fuels, nuclear, and hydro, varying by ISO/RTO markets, utilities, and state policies, affecting carbon emissions, pricing, reliability, and access.

Key Points

The US energy mix is the grid's source breakdown by region: fossil fuels, renewables, nuclear, and hydro.

✅ Check ISO or RTO dashboards for real-time generation by fuel source.

✅ Utilities may offer green power plans or RECs at modest premiums.

✅ Energy mix shifts with policy, pricing, and grid reliability needs.

There are few resources more important than energy. Sure, you may die if you don't eat for days. But your phone will die if you go too long without charging it. Energy feeds tech, the internet, city infrastructure, refrigerators, lights, and has evolved throughout U.S. history in profound ways. You get the idea. Yet unlike our other common needs, such as food, energy sources aren't exactly front of mind for most people. 

"I think a lot of people don't put a lot of bandwidth into thinking about this part of their lives," said Richard McMahon, the SVP of energy supply and finance at Edison Electric Institute, a trade group that represents investor-owned electric companies in the US. 

It makes sense. For most Americans, electricity is always there, and in many locations, there's not much of a choice involved, even as electricity demand is flat across the U.S. today. You sign up with a utility when you move into a new residence and pay your bills when they're due. 

But there's an important reality that indifference eschews: In 2018, a third of the energy-related carbon-dioxide emissions in the US came from the electric power sector, according to the US Energy Information Administration (EIA). 

A good chunk of that is from the residential sector, which consistently uses more energy than commercial customers, per EIA data.

Just as many people exercise choice when they eat, you typically also have a choice when it comes to your energy supply. That's not to say your current offering isn't what you want, or that switching will be easy or affordable, but "if you're a customer and want power with a certain attribute," McMahon said, "you can pretty much get it wherever you are." 

But first, you need to know the energy mix you have right now. As it turns out, it's not so straightforward. At all.

This brief guide may help. 

For some utility providers, you can find out if it publishes the energy mix online. Dominion Energy, which serves Idaho, North Carolina, Ohio, South Carolina, Utah, Virginia, West Virginia, and Wyoming, provides this information in a colored graphic. 

"Once you figure out who your utility is you can figure out what mix of resources they use," said Heidi Ratz, an electricity markets researcher at the World Resources Institute.

But not all utilities publish this information.

It has to do with their role in the grid and reflects utility industry trends in structure and markets. Some utility companies are vertically integrated; they generate power through nuclear plants or wind farms and distribute those electrons directly to their customers. Other utilities just distribute the power that different companies produce. 

Consider Consolidated Edison, or Con Ed, which distributes energy to parts of New York City. While reporting this story, Business Insider could not find information about the utility's energy mix online. When reached for comment, a spokesperson said, "we're indifferent to where it comes from."

That's because, in New York, distribution utilities like Con Ed often buy energy through a wholesale marketplace.

Take a look at this map. If you live in one of the colored regions, your electricity is sold on a wholesale market regulated by an organization called a regional transmission organization (RTO) or independent system operator (ISO). Distribution utilities like Con Ed often buy their energy through these markets, based on availability and cost, while raising questions about future utility revenue models as prices shift. 

Still, it's pretty easy to figure out where your energy comes from. Just look up the ISO or RTO website (such as NYISO or CAISO). Usually, these organizations will provide energy supply information in near-real time. 

That's exactly what Con Edison (which buys energy on the NYISO marketplace) suggested. As of Friday morning, roughly 40% of the energy on the market place was natural gas or other fossil fuels, 34% was nuclear, and about 22% was hydro. 

If you live in another region governed by an ISO or RTO, such as in most of California, you can do the same thing. Like NYISO, CAISO has a dashboard that shows (again, as of Friday morning) about 36% of the energy on the market comes from natural gas and more than 20% comes from renewables. 

In the map linked above, you'll notice that some of the ISOs and RTOs like MISO encompass enormous regions. That means that even if you figure out where the energy in your market comes from, it's not going to be geographically specific. But there are a couple of ways to drill down even further. 

The Environmental Protection Agency has a straightforward tool called Power Profiler. You can enter your zip code to see the fuel mix in your area. But it's not perfect. The data are from 2016 and, in some regions of the country like the upper Midwest, they aren't much more localized, and some import dirty electricity due to regional trading. 

The World Resources Institute also has a tool that allows you to see the electricity mix by state, based on 2017 data from EIA. These numbers represent power generation, not the electricity actually flowing into your sockets, but they offer a rough idea of what energy resources are operating in your state. 

One option is to check with your utility to see if it has a "green power" offering. Over 600 utilities across the country have one, according to the Climate Reality Project, though they often come at a slightly higher cost. It's typically on the scale of just a few more cents per kilowatt-hour. 

There are also independent, consumer-facing companies like Arcadia and Green Mountain Energy that allow you to source renewable energy, by virtually connecting you to community solar projects or purchasing Renewable Energy Certificates, or RECs, on your behalf, as America goes electric and more options emerge. 

"RECs measure an investment in a clean energy resource," Ratz said, in an email. "The goal of putting that resource on the grid is to push out the need for dirtier resources."

The good news: Even if you do nothing, your energy mix will get cleaner. Coal production has fallen to lows not seen since the 1980s, amid disruptions in coal and nuclear sectors that affect reliability and costs, while renewable electricity generation has doubled since 2008. So whether you like it or not, you'll be roped into the clean energy boom one way or another.

WA $600 Electricity Credit supports households with power bills as a budget stimulus, delivering an automatic rebate via Synergy and Horizon, funded by the Bell Group settlement to aid COVID-19 recovery and local spending.

Key Points

A one-off $600 power bill credit for all Synergy and Horizon residential accounts, funded by the Bell Group settlement.

✅ Automatic, not means-tested; applied to Synergy and Horizon accounts.

✅ Can offset upcoming bills or carry forward to future statements.

✅ Funded by Bell Group payout; aims to ease cost-of-living pressures.

Washington Premier Mark McGowan has announced more than a million households will receive a $600 electricity credit on their electricity account before their next bill.

The $650 million measure will form part of Thursday's pre-election state budget, similar to legislation to lower electricity rates in other jurisdictions, which has been delayed since May because of the pandemic and will help deflect criticism by the opposition that Labor hasn't done enough to stimulate WA's economy.

Mr McGowan made the announcement on Sunday while visiting a family in the electorate of Bicton.

"Here in WA, our state is in the best possible position as we continue our strong recovery from COVID-19, but times are still tough for many West Australians, and there is always more work to do," he said.

"[The credit] will mean WA families have a bit of extra money available in the lead up to Christmas.

"But I have a request, if this credit means you can spend some extra money, use it to support our local WA businesses."

The electricity bill credit will be automatically applied to every Synergy or Horizon residential account from Sunday, echoing moves such as reconnections for nonpayment by Hydro One in Canada.

It can be applied to future bills and will not be means tested.

"The $600 credit is fully funded through the recent Bell Group settlement, for the losses incurred in the Bell Group collapse in the early 1990s," Mr McGowan said.

"It made sense that these funds go straight back to Western Australians."

In September, the liquidator for the Bell Group and its finance arm distributed funds to its five major creditors, including $670 million to the WA government. The payment marked the close of the 30-year battle to recover taxpayer funds squandered during the WA Inc era of state politics.

The payout is the result of litigation stemming from the 1988 partnership between then Labor government and entrepreneur Alan Bond in acquiring major interests in Robert Holmes à Court’s failing Bell Group, following the 1987 stock market crash.

WA shadow minister for cost of living, Tony Krsticevic, said the $600 credit was returning money back into West Australian's pockets from "WA Labor's darkest days".

“This is taxpayers’ money out of a levy which was brought in to pay for Labor’s scandalous WA Inc losses of $450 million in the 1980s,” he said.

“This money should be returned to West Australians.

“WA families are in desperate need of it because they are struggling under cost of living increases of $850 every year since 2017 under WA Labor, amid concerns elsewhere that an electricity recovery rate could lead to higher hydro bills.

“But they need more than just a one-off payment. These $850 cost of living increases are an on-going burden.”

Prior to the onset of the coronavirus pandemic, the opposition believed it was gaining traction by attacking the government's increases to fees and charges in its first three budgets, and by urging an electricity market overhaul to favor consumers.

Last year, Labor increased household fees and charges by $127.77, which came on top of increases over the prior two budgets, as other jurisdictions faced hydro rate increases of around 3 per cent.

According the state's annual report on its finances released in September, the $2.6 billion budget surplus forecast in the at the end of 2019 had been reduced by $920 million to $1.7 billion despite the impact of the coronavirus.

But total public sector net debt was at $35.4 billion, down from the $36.1 billion revision at the end of 2019 in the mid-year review.

Renewable Energy Breakthroughs drive quantum dots solar efficiency, Air-gen protein nanowires harvesting humidity, and cellulose membranes for flow batteries, enabling printable photovoltaics, 24/7 clean power, and low-cost grid storage at commercial scale.

Key Points

Advances like quantum dot solar, Air-gen, and cellulose flow battery membranes that improve clean power and storage.

✅ Quantum dots raise solar conversion efficiency, are printable

✅ Air-gen harvests electricity from humidity with protein nanowires

✅ Cellulose membranes cut flow battery costs, aid grid storage

Science never sleeps. The quest to find new and better ways to do things continues in thousands of laboratories around the world. Today, the global economy is based on the use of electricity, and one analysis shows wind and solar potential could meet 80% of US demand, underscoring what is possible. If there was a way to harness all the energy from the sun that falls on the Earth every day, there would be enough of electricity available to meet the needs of every man, woman, and child on the planet with plenty left over. That day is getting closer all the time. Here are three reasons why.

Quantum Dots Make Better Solar Panels
According to Science Daily, researchers at the University of Queensland have set a new world record for the conversion of solar energy to electricity using quantum dots — which pass electrons between one another and generate electrical current when exposed to solar energy in a solar cell device. The solar devices they developed have beaten the existing solar conversion record by 25%.

“Conventional solar technologies use rigid, expensive materials. The new class of quantum dots the university has developed are flexible and printable,” says professor Lianzhou Wang, who leads the research team. “This opens up a huge range of potential applications, including the possibility to use it as a transparent skin to power cars, planes, homes and wearable technology. Eventually it could play a major part in meeting the United Nations’ goal to increase the share of renewable energy in the global energy mix.”

“This new generation of quantum dots is compatible with more affordable and large-scale printable technologies,” he adds. “The near 25% improvement in efficiency we have achieved over the previous world record is important. It is effectively the difference between quantum dot solar cell technology being an exciting prospect and being commercially viable.” The research was published on January 20 in the journal Nature Energy.

Electricity From Thin Air
Science Daily also reports that researchers at UMass Amherst also have interesting news. They claim they created a device called an Air-gen, short for air powered generator. (Note: recently we reported on other research that makes electricity from rainwater.) The device uses protein nanowires created by a microbe called Geobacter. Those nanowires can generate electricity from thin air by tapping the water vapor present naturally in the atmosphere. “We are literally making electricity out of thin air. The Air-gen generates clean energy 24/7. It’s the most amazing and exciting application of protein nanowires yet,” researchers Jun Yao and Derek Lovely say. There work was published February 17 in the journal Nature.

The new technology developed in Yao’s lab is non-polluting, renewable, and low-cost. It can generate power even in areas with extremely low humidity such as the Sahara Desert. It has significant advantages over other forms of renewable energy including solar and wind, Lovley says, because unlike these other renewable energy sources, the Air-gen does not require sunlight or wind, and “it even works indoors,” a point underscored by ongoing grid challenges that slow full renewable adoption.

Yao says, “The ultimate goal is to make large-scale systems. For example, the technology might be incorporated into wall paint that could help power your home. Or, we may develop stand-alone air-powered generators that supply electricity off the grid, and in parallel others are advancing bio-inspired fuel cells that could complement such devices. Once we get to an industrial scale for wire production, I fully expect that we can make large systems that will make a major contribution to sustainable energy production. This is just the beginning of a new era of protein based electronic devices.”

Improved Membranes For Flow Batteries From Cellulose
Storing energy is almost as important to decarbonizing the environment as making it in the first place, with the rise of affordable solar batteries improving integration.  There are dozens if not hundreds of ways to store electricity and they all work to one degree or another. The difference between which ones are commercially viable and ones that are not often comes down to money.

Flow batteries — one approach among many, including fuel cells for renewable storage — use two liquid electrolytes — one positively charged and one negatively charged — separated by a membrane that allows electrons to pass back and forth between them. The problem is, the liquids are highly corrosive. The membranes used today are expensive — more than $1,300 per square meter.

Phys.org reports that Hongli Zhu, an assistant professor of mechanical and industrial engineering at Northeastern University, has successfully created a membrane for use in flow batteries that is made from cellulose and costs just $147.68 per square meter. Reducing the cost of something by 90% is the kind of news that gets people knocking on your door.

The membrane uses nanocrystals derived from cellulose in combination with a polymer known as polyvinylidene fluoride-hexafluoropropylene.  The naturally derived membrane is especially efficient because its cellular structure contains thousands of hydroxyl groups, which involve bonds of hydrogen and oxygen that make it easy for water to be transported in plants and trees.

In flow batteries, that molecular makeup speeds the transport of protons as they flow through the membrane. “For these materials, one of the challenges is that it is difficult to find a polymer that is proton conductive and that is also a material that is very stable in the flowing acid,” Zhu says.

Cellulose can be extracted from natural sources including algae, solid waste, and bacteria. “A lot of material in nature is a composite, and if we disintegrate its components, we can use it to extract cellulose,” Zhu says. “Like waste from our yard, and a lot of solid waste that we don’t always know what to do with.”

Flow batteries can store large amounts of electricity over long periods of time — provided the membrane between the storage tanks doesn’t break down. To store more electricity, simply make the tanks larger, which makes them ideal for grid storage applications where there is often plenty of room to install them. Slashing the cost of the membrane will make them much more attractive to renewable energy developers and help move the clean energy revolution forward.

The Takeaway
The fossil fuel crazies won’t give up easily. They have too much to lose and couldn’t care less if life on Earth ceases to exist for a few million years, just so long as they get to profit from their investments. But they are experiencing a death of a thousand cuts. None of the breakthroughs discussed above will end thermal power generation all by itself, but all of them, together with hundreds more just like them happening every day, every week, and every month, even as we confront clean energy's hidden costs across supply chains, are slowly writing the epitaph for fossil fuels.

And here’s a further note. A person of Chinese ancestry is the leader of all three research efforts reported on above. These are precisely the people being targeted by the United States government at the moment as it ratchets up its war on immigrants and anybody who cannot trace their ancestry to northern Europe. Imagine for a moment what will happen to America when researchers like them depart for countries where they are welcome instead of despised.

OSW CareerMatch Offshore Wind Job Fair convenes industry leaders, supply chain employers, and skilled candidates at IPF 2020 in Providence, Rhode Island, spotlighting workforce development, training programs, and near-term hiring for U.S. offshore wind projects.

Key Points

An IPF 2020 job fair connecting offshore wind employers, advancing workforce development in Providence, RI.

✅ National job fair at IPF 2020, Providence, RI

✅ Connects supply chain employers with skilled candidates

✅ Includes a workforce development and education summit

The Business Network for Offshore Wind, the leading non-profit advocate for U.S. offshore wind at the state, federal and global levels, amid a U.S. grid warning about coronavirus impacts, will host its seventh annual International Partnership Forum (IPF) on April 21-24, 2020 in Providence, Rhode Island. 

New this year: the first-ever national offshore wind industry job fair plus a half-day workforce development summit, in partnership with Skills for Rhode Island’s Future. The OSW CareerMatch, will showcase jobs at top-tier companies seeking to grow the workforce of the future, informed by young people's interest in electricity careers, and recruit qualified candidates. The Offshore Wind Workforce Development and Education Summit, an invitation-only event, will bring together educators, stakeholders, and industry leaders to address current energy training programs, identify industry employment needs, required skillsets, and how organizations can fulfill these near-term needs. CareerMatch will take place 8:30 a.m. to 1:00 p.m. on Tuesday, April 21, and the Workforce Summit from 12:30 p.m. to 4:00 p.m., both at the Rhode Island Convention Center. 

“The U.S. offshore wind industry has reached the stage that, in order to successfully develop and meet new project demands, will require an available and qualified workforce,” said Liz Burdock, CEO and president of the Business Network for Offshore Wind, noting worker safety concerns in other energy sectors. “This first-ever national Job Fair will allow top-tier supply chain companies to connect with skilled individuals to discuss projects that are going on as they speak.” 

“Hosting the first-of-its-kind offshore wind energy job fair in The Ocean State is apropos,” said Nina Pande, executive director of Skills for Rhode Island’s Future, as future of work investments accelerate across the electricity sector. “Our organization is thrilled to have the unique opportunity to help convene talent at OSW CareerMatch to engage with the employers across the offshore wind supply chain.”

The annual IPF conference is the premier event for the offshore wind supply chain, which is now projected to be a $70 billion revenue opportunity through 2030. Fully developing this supply chain will foster local economic growth, provide thousands of jobs, adapt to shifts like working from home electricity demand, and help offshore wind energy meet its potential. If fully built out worldwide, offshore wind could power 18 times the world’s current electricity needs.    

The exhibit and conference sells out every year and is again on track to draw over 2,500 industry professionals representing over 575 companies, all focused on sharing valuable insights on how to move the emerging U.S. wind industry forward, including operational resilience such as on-site staffing plans during the outbreak. The full conference schedule may be seen online here. More details, including special guest speakers, will be announced soon.

EPA Power Plant Emissions Rule proposes strict greenhouse gas limits for coal and gas units, leveraging carbon capture (CCS) under the Clean Air Act to cut CO2 and accelerate decarbonization of the U.S. grid.

Key Points

A proposed EPA rule setting CO2 limits for coal and gas plants, using CCS to cut power-sector greenhouse gases.

✅ Applies to existing and new coal and large gas units

✅ Targets near-zero CO2 by 2038 via CCS or retirement

✅ Cites grid, health, and climate benefits; faces legal challenges

The Biden administration has proposed new limits on greenhouse gas emissions from coal- and gas-fired power plants, its most ambitious effort yet to roll back planet-warming pollution from the nation’s second-largest contributor to climate change.

A rule announced by the Environmental Protection Agency could force power plants to capture smokestack emissions using a technology that has long been promised but is not used widely in the United States, and arrives amid changes stemming from the NEPA rewrite that affect project reviews.

“This administration is committed to meeting the urgency of the climate crisis and taking the necessary actions required,″ said EPA Administrator Michael Regan.

The plan would not only “improve air quality nationwide, but it will bring substantial health benefits to communities all across the country, especially our front-line communities ... that have unjustly borne the burden of pollution for decades,” Regan said in a speech at the University of Maryland.

President Joe Biden, whose climate agenda includes a clean electricity standard as a key pillar, called the plan “a major step forward in the climate crisis and protecting public health.”

If finalized, the proposed regulation would mark the first time the federal government has restricted carbon dioxide emissions from existing power plants, following a Trump-era replacement of Obama’s power plant overhaul, which generate about 25% of U.S. greenhouse gas pollution, second only to the transportation sector. The rule also would apply to future electric plants and would avoid up to 617 million metric tons of carbon dioxide through 2042, equivalent to annual emissions of 137 million passenger vehicles, the EPA said.

Almost all coal plants — along with large, frequently used gas-fired plants — would have to cut or capture nearly all their carbon dioxide emissions by 2038, the EPA said, a timeline that echoed concerns raised during proposed electricity pricing changes in the prior administration. Plants that cannot meet the new standards would be forced to retire.

The plan is likely to be challenged by industry groups and Republican-leaning states, much like litigation over the Affordable Clean Energy rule unfolded in recent years. They have accused the Democratic administration of overreach on environmental regulations and warn of a pending reliability crisis for the electric grid. The power plant rule is one of at least a half-dozen EPA rules limiting power plant emissions and wastewater treatment rules.

“It’s truly an onslaught” of government regulation “designed to shut down the coal fleet prematurely,″ said Rich Nolan, president and CEO of the National Mining Association.

Regan denied that the power plant rule was aimed at shutting down the coal sector, but acknowledged — even after the end to the 'war on coal' rhetoric — “We will see some coal retirements.”
