Sherry Eaton pulled into the driveway of her rural, high-desert home to see one of several giant wind turbines being assembled a half-mile away.

"I started to cry," Eaton, 57, recalled of her first sight of the Willow Creek Wind Project in late July. "They're going to be hanging over the back of our house, and now there's the medical thing."

"The medical thing" is new research suggesting that living close to wind turbines, as Eaton and her 60-year-old husband, Mike, soon will be doing, can cause sleep disorders, difficulty with equilibrium, headaches, childhood "night terrors" and other health problems.

Dozens of wind turbines are taking shape along Oregon 74, a designated Oregon Scenic Byway, near the home the Eatons have shared for 19 years.

Dr. Nina Pierpont of Malone, N.Y., coined the phrase "wind turbine syndrome" for what she says happens to some people living near wind energy farms. She has made the phrase part of the title of a book she's written called Wind Turbine Syndrome: A Report on the Natural Experiment. It is scheduled for publication next month by K-Selected Press of Santa Fe, N.M.

In contrast to those who consider wind turbines clean, green and an ideal source of renewable energy, Pierpont says living or working too close to them has a downside. Her research says wind turbines should never be built closer than two miles from homes.

Pierpont, 53, is a 1991 graduate of Johns Hopkins University School of Medicine and has a doctorate in population biology from Princeton University. Her interest was piqued by a wind farm being built near her upstate New York home, and she studied 10 families living near wind turbines built since 2004 in Canada, England, Ireland, Italy and the United States.

Pierpont's findings suggest that low-frequency noise and vibration generated by wind machines can have an effect on the inner ear, triggering headaches; difficulty sleeping; tinnitus, or ringing in the ears; learning and mood disorders; panic attacks; irritability; disruption of equilibrium, concentration and memory; and childhood behavior problems.

Concerns also are coming out of Europe about low-frequency noise from newly built wind turbines.

For example, British physician Amanda Harry, in a February 2007 article titled "Wind Turbines, Noise and Health," wrote of 39 people, including residents of New Zealand and Australia, who suffered from the sounds emitted by wind turbines.

According to Pierpont, eight of the 10 families in her study moved out of their homes.

"All these problems were resolved as soon as these people got away from the turbines, got in the car and drove away from the house," she said.

Mike Logsdon, director of development for Invenergy, developer of the 48 wind turbines under construction in the Willow Creek Wind Project, said he's heard of Pierpont's findings, but his 5-year-old company doesn't find them credible.

"We've had a number of other wind farms over the country and residents living by them and never had any problems," Logsdon said.

Invenergy has built and operates wind farms in Canada and Poland and in 12 states in the United States, Logsdon said. The company has 1,200 megawatts in production and is building 600 megawatts this year. The 72-megawatt Willow Creek Wind Project near the Eatons' home is scheduled to start producing electricity Jan. 1.

If Pierpont's theories gain acceptance, decisions on where future wind energy farms are built could be affected.

Last year, more than one-third of all new power capacity in the United States, roughly 5,000 megawatts, was generated by wind turbines, said Joseph Beamon, spokesman for the U.S. Department of Energy in Washington.

Meanwhile, a U.S. Department of Energy report said demand for electricity is likely to grow 40 percent in the next 22 years in the United States alone, with 20 percent of the nation's power generated by wind turbines, he said.

The Eatons and their neighbors have more to worry about than the Willow Creek Project. Approval was given July 25 by the Oregon Facilities Siting Council for construction of as many as 400 more wind turbines in the nearby Shepherds Flat Wind Project spanning parts of Gilliam and Morrow counties. The planned 909-megawatt project by Caithness Energy of Chicago is expected to be the largest wind farm on earth, generating enough peak energy to power 225,000 homes.

"Man, this whole country is going to be windmills," said a dismayed Denny Wade, 59, a railroad worker and neighbor of the Eatons.

He and his wife, Lorrie, a 53-year-old schoolteacher, live three-quarters of a mile from one of Willow Creek's turbines. The Wades had planned to sell the home where they've lived for four years and build a retirement home on a knoll 200 yards away with a view of Mount Hood.

"Now, the view that it had is all windmills," Wade said. "I didn't move out there to view windmills."

But Denny Wade's larger concern is his vulnerability to migraine headaches. Although not everyone living near wind turbines experienced headaches, Pierpont's research suggests "everyone with pre-existing migraines" developed headaches by living near the wind generators.

The Wades scrapped plans to build a new home and hope to sell their 42 acres and move, they said.

Morrow County planner Carla McLane said potential health issues never were raised during the planning process in her county, and the opportunity to appeal has passed. The potential effects of turbines on the scenic values of Oregon 74 never were brought up in hearings he attended, said Terry Tallman, Morrow County Commission chairman.

Generally, wind energy farms have been welcomed in this sparsely settled corner of the state, Tallman said. Tax revenues from the wind farms will be distributed to the counties, public schools, park and recreation districts and fire departments, he said.

"Everybody that I've talked to has been very happy," he said, adding that some on whose property the turbines are being built intend to retire on the income they receive.

"I think it's a good thing," Ron Wyscaver, 40, a neighbor of the Eatons and Wades, said of the wind turbines.

Caithness first proposed a 105-megawatt Shepherds Flat Project in 2002, then applied to the state for the larger project two years ago, McLane said. The project was so large it went to the Energy Facilities Siting Council, where it received the go-ahead to start construction.

Potential medial problems aside, Sherry Eaton says the wind turbines will wreck the tranquillity the couple came to this remote setting to find. She drives 90 miles a day to and from her job in Hermiston so they can live in the high-desert setting.

"When you come home from work, everything drains away from you because it's so quiet and peaceful," she said, adding that's about to end.

"Now we are going to have to listen to those windmills: Whoosh! Whoosh! Whoosh!" she said.

Renewable energy now cheapest option for new electricity in most of the world: Report

Renewable Energy Cost Trends highlight IRENA data showing solar and wind undercut coal, as utility-scale projects drive lower levelized electricity costs worldwide, with the Middle East and UAE advancing mega solar parks.

 

Key Points

They track how solar and wind undercut new fossil fuels as utility-scale costs drop and investment accelerates.

✅ IRENA reports renewables cheapest for new installations

✅ Solar and wind LCOE fell sharply since 2010

✅ Middle East and UAE scale mega utility projects

 

Renewable energy is now the cheapest option for new electricity installation in most of the world, a report from the International Renewable Energy Agency (IRENA) on Tuesday said.

Renewable power projects have undercut traditional coal fuel plants, with solar and wind power costs in particular falling as record-breaking growth continues worldwide.

“Installing new renewables increasingly costs less than the cheapest fossil fuels. With or without the health and economic crisis, dirty coal plants were overdue to be consigned to the past, said Francesco La Camera, director-general of IRENA said in the report.

In 2019, renewables accounted for around 72 percent of all new capacity added worldwide, IRENA said, following a 2016 record year that highlighted the momentum, with lowering costs and technological improvements in solar and wind power helping this dynamic. For solar energy, IRENA notes that the cost for electricity from utility-scale plants fell by 82 percent in the decade between 2010 and 2019, as China's solar PV growth underscored in 2016.

“More than half of the renewable capacity added in 2019 achieved lower electricity costs than new coal, while new solar and wind projects are also undercutting the cheapest and least sustainable of existing coal-fired plants,” Camera added.

Costs for solar and wind power also fell year-on-year by 13 and 9 percent, respectively, with offshore wind costs showing steep declines as well. In 2019, more than half of all newly commissioned utility-scale renewable power plants provided electricity cheaper than the lowest cost of a new fossil fuel plant.

The Middle East

In mid-May, a report by UK-based law firm Ashurst suggested the Middle East is the second most popular region for renewable energy investment after North America, at a time when clean energy investment is outpacing fossil fuels.

The region is home to some of the largest renewable energy bets in the world, with Saudi wind expansion gathering pace. The UAE, for instance, is currently developing the Mohammed Bin Rashid Solar Park, the world’s largest concentrated solar power project in the world.

Around 26 percent of Middle East respondents in Ashurst’s survey said that they were presently investing in energy transition, marking the region as the most popular for current investment in renewables, while 11 percent added that they were considering investing.

In North America, the most popular region, 28 percent said that they were currently investing, with 11 percent stating they are considering investing.

Consumers Coalition wants Manitoba Hydro?s proposed rate increase rejected

Manitoba Hydro Interim Rate Increase faces PUB scrutiny as consumers coalition challenges a 5% electricity rate hike, citing drought planning, retained earnings, affordability, transparency, and impacts on fixed incomes and northern communities.

 

Key Points

A proposed 5% electricity rate hike under PUB review, opposed by consumers citing drought planning and affordability.

✅ Coalition backs 2% hike; 5% seen as undue burden

✅ PUB review sought; interim process lacks transparency

✅ Retained earnings, efficiencies cited to offset drought

 

The Consumers Coalition is urging the Public Utilities Board (PUB) to reject Manitoba Hydro’s current interim rate increase application, amid ongoing debates about Hydro governance and policy.

Hydro is requesting a five per cent jump in electricity rates starting on January 1, claiming drought conditions warrant the increase but the coalition disagrees, saying a two per cent increase would be sufficient.

The coalition, which includes Harvest Manitoba, the Consumers’ Association of Canada-Manitoba, and the Aboriginal Council of Winnipeg, said a 5 per cent rate increase would put an unnecessary strain on consumer budgets, especially for those on fixed incomes or living up north.

"We feel that, in many ways, Manitobans have already paid for this drought," said Gloria Desorcy, executive director of the Consumers’ Association of Canada - Manitoba.

The coalition argues that hydroelectric companies already plan for droughts and that hydro should be using past earnings to mitigate any losses.

The group claims drought conditions would have added about 0.8 per cent to Hydro’s bottom line. They said remaining revenues from a two per cent increase could then be used to offset the increased costs of major projects like the Keeyask generating station and service its growing debt obligations.

The group also said Hydro is financially secure and is projecting a positive net income of $112 million next year without rate increases, even as utility profits can swing with market conditions, assuming the drought doesn’t continue.

They argue Hydro can use retained earnings as a tool to mitigate losses, rather than relying on deferral accounting that shifts costs, and find further efficiencies within the corporation.

"So we said two per cent, which is much more palatable for consumers especially at the time when so many consumers are struggling with so many higher bills,” said Desorcy.

According to the coalition’s calculations, that works out to a $2-4 increase per month, and debates such as ending off-peak pricing in Ontario show how design affects bills, depending on whether electricity is used for heating, but it could be higher.

The coalition said their proposed two per cent rate increase should be applied to all Manitoba Hydro customers and have a set expiration date of January 1, 2023.

Another issue, according to the coalition, is the process of an interim rate application does not provide any meaningful transparency and accountability, whereas recent OEB decisions in Ontario have outlined more robust public processes.

Desorcy said the next step is up to the PUB, though board upheaval at Hydro One in Ontario shows how governance shifts can influence outcomes.

The board is expected to decide on the proposed increase in the next couple of weeks.

N.L. lags behind Canada in energy efficiency, but there's a silver lining to the stats

Newfoundland and Labrador Energy Efficiency faces low rankings yet signs of progress: heat pumps, EV charging networks, stricter building codes, electrification to tap Muskrat Falls power and cut greenhouse gas emissions and energy poverty.

 

Key Points

Policies and programs improving N.L.'s energy use via electrification, EVs, heat pumps, and stronger building codes.

✅ Ranks last provincially but showing policy momentum

✅ Heat pump grants and EV charging network underway

✅ Stronger building codes and electrification can cut emissions

 

Ah, another day, another depressing study that places Newfoundland and Labrador as lagging behind the rest of Canada.

We've been in this place before — least-fit kids, lowest birthrate — and now we can add a new dubious distinction to the pile: a ranking of the provinces according to energy efficiency placed Newfoundland and Labrador last.

Efficiency Canada released its first-ever provincial scorecard Nov. 20, comparing energy efficiency policies among the provinces. With energy efficiency a key part of reducing greenhouse gas emissions, Newfoundland and Labrador sat in 10th place, noted for its lack of policies on everything from promoting EV uptake in Atlantic Canada to improving efficient construction codes.

But before you click away to a happier story (about, say, a feline Instagram superstar) one of the scorecard's authors says there's a silver lining to the statistics.

"It's not that Newfoundland and Labrador is doing anything badly; it's just that it could do more," said Brendan Haley, the policy director at Efficiency Canada, a new think tank based at Carleton University.

"There's just a general lack of attention to implementing efficiency policies relative to other jurisdictions, including New Brunswick's EV rebate programs on transportation."

Looking at the scorecard and comparing N.L. with British Columbia, which snagged the No. 1 spot, isn't a great look. B.C. scored 56 points out of a possible 100, while N.L. got just 15.

Haley pointed out that B.C.'s provincial government is charting progress toward 2032, when all new builds will have to be net-zero energy ready; that is, buildings that can produce as much clean energy as they consume.  

While it might not be feasible to emulate that to a T here, Haley said the province could be mandating better energy efficiency standards for new, large building projects, and, at the same time, promote electrification of such projects as a way to soak up some of that surplus Muskrat Falls electricity.

Staring down Muskrat's 'extraordinary' pressure on N.L. electricity rates

It's impossible to talk about energy efficiency in N.L. without considering that dam dilemma. As Muskrat Falls comes online, likely at the end of 2020, customer power rates are set to rise in order to pay for it, and the province is still trying to figure out the headache that is rate mitigation.

"There is a strategic choice to be made in Newfoundland and Labrador," Haley told CBC Radio's On The Go.

While having more customers using Muskrat Falls power can help with rate mitigation, including through initiatives like N.L.'s EV push to grow demand, Haley noted simply using its excess electricity for the sake of it isn't a great goal.

"That should not be an excuse, I think, to almost have a policy of wasting energy on purpose, or saying that we don't need programs that help save electricity anymore," he said.

Energy poverty
Lots of N.L. homeowners are currently feeling a chill from the spectre of rising electricity rates.

Of course, that draft could be coming from a poorly insulated and heated house, as Efficiency Canada noted 38 per cent of all households in N.L. live in what it calls "energy poverty," where they spend more than six per cent of their after-tax income on energy — that's the second highest such rate in the country.

That poverty speaks for a need for N.L.to boost efficiency incentives for vulnerable populations, although Haley noted the government is making progress. The province recently expanded its home energy savings program, doubling in the last budget year to $2 million, which gives grants to low income households for upgrades like insulation.

Can you guess what products are selling like hotcakes as Muskrat Falls looms? Heat pumps

And since Efficiency Canada compiled its scorecard, the province has introduced a $1-million heat pump program, in which 1,000 homeowners could receive $1,000 toward the purchase of a heat pump. 

That program began accepting applications Oct. 15, and one month in, has had 682 people apply, according to the Department of Municipal Affairs and Environment, along with thousands of inquiries.

Heat pump popularity
Even without that program, heat pump sales have skyrocketed in the province since 2017. That popularity doesn't come as much of a surprise to Darren Brake, the president of KSAB Construction in Corner Brook.

With more than two decades in the home building business, he's been seeing consumer demand for home energy efficiency rise to the point where a year ago, his company transitioned into only building third-party certified energy efficient homes.

"Everybody's really concerned about the escalating power costs and energy costs, I assume because of Muskrat Falls," he said.

"It's evolving now, as we speak. Everybody is all about that monthly payment."

Brake uses spray foam installation in every house he builds, to seal up any potential leaks. Without sealing the building envelope, he says, a heat pump is far less efficient. (Lindsay Bird/CBC)
And in the weakest housing market in the province in half a century, Brake has been steadily moving his, building and selling seven in the last year.

Brake's houses include heat pumps, but he said the real savings come from their heavily insulated walls, roof and floors. Homeowners looking to install a heat pump in their leaky old house, he said, won't see lower power bills in quite the same way.

"They are energy efficient, but it's more about the building envelope to make a home efficient and easy to heat. You can put a heat pump in an older home that leaks a lot of air, and you won't get the same results," he said.

Charging network coming
The other big piece to the efficiency puzzle — in the scorecard's eyes — is electric vehicles. Those could, again, use some of that Muskrat Falls energy, as well as curtail gas guzzling, but Efficiency Canada pointed to a lack of policies and incentives surrounding electrifying transportation, such as Nova Scotia's vehicle-to-grid pilot that illustrates innovation elsewhere.

Unlike Quebec or B.C., the province doesn't offer a rebate for buying EVs, even as N.W.T. encourages EVs through targeted measures, and while electric vehicles got loud applause at the House of Assembly last week, it was absent of any policy or announcement beyond the province unveiling a EV licence plate design to be used in the near future.

Electric-vehicle charging network planned for N.L. in 2020

But since the scorecard was tallied, NL Hydro has unveiled plans for a Level 3 charging network for EVs across the island, dependent on funding, with N.L.'s first fast-charging network seen as just the beginning for local drivers.

NL Hydro says while its request for proposals for an island-wide charging network closed earlier in November, there is no progress update yet, even as N.B.'s fast-charging rollout advances along the Trans-Canada. (Credit: iStock/Getty Images)
That cash appears to still be in limbo, as "we are still progressing through the funding process," said an NL Hydro spokesperson in an email, with no "additional details to release at this time."

Still, the promise of a charging network — plus the swift uptake on the heat pump program — could boost N.L.'s energy efficiency scorecard next time it's tallied, said Haley.

"It is encouraging to see the province moving forward on smart and efficient electrification," he said.

Philippines Ranks Highest in Coal-Generated Power Dependency

Philippines coal dependency underscores energy transition challenges, climate change risks, and air pollution, as rising electricity demand, fossil fuels, and emissions shape policy shifts toward renewable energy, grid reliability, and sustainable development.

 

Key Points

It is rising reliance on coal for power, driven by demand and cost, with climate, air pollution, and policy risks.

✅ Driven by rising demand, affordability, and grid reliability.

✅ Worsens emissions, air pollution, and public health burdens.

✅ Policy shifts aim at renewable energy, efficiency, and standards.

 

In a striking development, the Philippines has surpassed China and Indonesia to become the nation most dependent on coal-generated power in recent years. This shift highlights significant implications for the country's energy strategy, environmental policies, and its commitment to sustainable development, and comes as global power demand continues to surge worldwide.

Rising Dependency on Coal

The Philippines' increasing reliance on coal-generated power is driven by several factors, including rapid economic growth, rising electricity demand, and regional uncertainties in China's electricity sector that influence fuel markets, and the perceived affordability and reliability of coal as an energy source. Coal has historically been a key component of the Philippines' energy mix, providing a stable supply of electricity to support industrialization and urbanization efforts.

Environmental and Health Impacts

Despite its economic benefits, coal-generated power comes with significant environmental and health costs, especially as soaring electricity and coal use amplifies exposure to pollution. Coal combustion releases greenhouse gases such as carbon dioxide, contributing to global warming and climate change. Additionally, coal-fired power plants emit pollutants such as sulfur dioxide, nitrogen oxides, and particulate matter, which pose health risks to nearby communities and degrade air quality.

Policy and Regulatory Landscape

The Philippines' energy policies have evolved to address the challenges posed by coal dependency while promoting sustainable alternatives. The government has introduced initiatives to encourage renewable energy development, improve energy efficiency, and, alongside stricter emissions standards on coal-fired power plants, is evaluating nuclear power for inclusion in the energy mix to meet future demand. However, balancing economic growth with environmental protection remains a complex and ongoing challenge.

International and Domestic Pressures

Internationally, there is growing pressure on countries to reduce reliance on fossil fuels and transition towards cleaner energy sources as part of global climate commitments under the Paris Agreement, illustrated by the United Kingdom's plan to end coal power within its grid. The Philippines' status as the most coal-dependent nation underscores the urgency for policymakers to accelerate the shift towards renewable energy and reduce carbon emissions to mitigate climate impacts.

Challenges and Opportunities

Transitioning away from coal-generated power presents both challenges and opportunities for the Philippines. Challenges include overcoming entrenched interests in the coal industry, addressing energy security concerns, and navigating the economic implications of energy transition, particularly as clean energy investment in developing nations has recently declined, adding financial headwinds. However, embracing renewable energy offers opportunities to diversify the energy mix, reduce dependence on imported fuels, create green jobs, and improve energy access in remote areas.

Community and Stakeholder Engagement

Engaging communities and stakeholders is crucial in shaping the Philippines' energy transition strategy. Local residents, environmental advocates, industry leaders, and policymakers play essential roles in fostering dialogue, raising awareness about the benefits of renewable energy, and advocating for policies that promote sustainable development and protect public health.

Future Outlook

The Philippines' path towards reducing coal dependency and advancing renewable energy is critical to achieving long-term sustainability and resilience against climate change impacts. By investing in renewable energy infrastructure, enhancing energy efficiency measures, and fostering innovation in clean technologies, as renewables poised to eclipse coal indicate broader momentum, the country can mitigate environmental risks, improve energy security, and contribute to global efforts to combat climate change.

Conclusion

As the Philippines surpasses China and Indonesia in coal-generated power dependency, the nation faces pivotal decisions regarding its energy future. Balancing economic growth with environmental stewardship requires strategic investments in renewable energy, robust policy frameworks, and proactive engagement with stakeholders to achieve a sustainable and resilient energy system. By prioritizing clean energy solutions, the Philippines can pave the way towards a greener and more sustainable future for generations to come.

China to build 2,000-MW Lawa hydropower station on Jinsha River

Lawa Hydropower Station approved on the Jinsha River, a Yangtze tributary, delivers 2,000 MW via four units; 784 ft dam, 12 sq mi reservoir, Sichuan-Tibet site, US$4.59b investment, Huadian stake, renewable energy generation.

 

Key Points

A 2,000 MW dam project on the Jinsha River with four units, a 784 ft barrier, and 8.36 billion kWh annual output.

✅ Sichuan-Tibet junction on the Jinsha River

✅ 2,000 MW capacity; four turbine-generator units

✅ 8.36 bn kWh/yr; US$4.59b total; Huadian 48% stake

 

China has approved construction of the 2,000-MW Lawa hydropower station, a Yangtze tributary hydropower project on the Jinsha River, multiple news agencies are reporting.

Lawa, at the junction of Sichuan province and the Tibet autonomous region, will feature a 784-foot-high dam and the reservoir will submerge about 12 square miles of land. The Jinsha River is a tributary of the Yangtze River, and the project aligns with green hydrogen development in China.

The National Development and Reform Commission of the People’s Republic of China, which also guides China's nuclear energy development as part of national planning, is reported to have said that four turbine-generator units will be installed, and the project is expected to produce about 8.36 billion kWh of electricity annually.

Total investment in the project is to be US$4.59 billion, and Huadian Group Co. Ltd. will have a 48% stake in the project, reflecting overseas power infrastructure activity, with minority stakes held by provincial firms, according to China Daily.

In other recent news in China, Andritz received an order in December 2018 to supply four 350-MW reversible pump-turbines and motor-generators, alongside progress in compressed air generation technologies, for the 1,400-MW ZhenAn pumped storage plant in Shaanxi province.

Data Show Clean Power Increasing, Fossil Fuel Decreasing in California

California clean electricity accelerates with renewables as solar and wind surge, battery storage strengthens grid resilience, natural gas declines, and coal fades, advancing SB 100 targets, carbon neutrality goals, and affordable, reliable power statewide.

 

Key Points

California clean electricity is the state's transition to renewable, zero-carbon power, scaling solar, wind and storage.

✅ Solar generation up nearly 20x since 2012

✅ Natural gas power down 20%; coal nearly phased out

✅ Battery storage shifts daytime surplus to evening demand

 

Data from the California Energy Commission (CEC) highlight California’s continued progress toward building a more resilient grid, achieving 100 percent clean electricity and meeting the state’s carbon neutrality goals.

Analysis of the state’s Total System Electric Generation report shows how California’s power mix has changed over the last decade. Since 2012:

Solar generation increased nearly twentyfold from 2,609 gigawatt-hours (GWh) to 48,950 GWh.

  • Wind generation grew by 63 percent.
  • Natural gas generation decreased 20 percent.
  • Coal has been nearly phased-out of the power mix, and renewable electricity surpassed coal nationally in 2022 as well.

In addition to total utility generation, rooftop solar increased by 10 times generating 24,309 GWh of clean power in 2022. The state’s expanding fleet of battery storage resources also help support the grid by charging during the day using excess renewable power for use in the evening.

“This latest report card showing how solar energy boomed as natural gas powered electricity experienced a steady 20 percent decline over the last decade is encouraging,” said CEC Vice Chair Siva Gunda. “Even as climate impacts become increasingly severe, California remains committed to transitioning away from polluting fossil fuels and delivering on the promise to build a future power grid that is clean, reliable and affordable.”

Senate Bill 100 (2018) requires 100 percent of California’s electric retail sales be supplied by renewable and zero-carbon energy sources by 2045. To keep the state on track, last year Governor Gavin Newsom signed SB 1020, establishing interim targets of 90 percent clean electricity by 2035 and 95 percent by 2040.

The state monitors progress through the Renewables Portfolio Standard (RPS), which tracks the power mix of retail sales, and regional peers such as Nevada's RPS progress offer useful comparison. The latest data show that in 2021 more than 37 percent of the state’s electricity came from RPS-eligible sources such as solar and wind, an increase of 2.7 percent compared to 2020. When combined with other sources of zero-carbon energy such as large hydroelectric generation and nuclear, nearly 59 percent of the state’s retail electricity sales came from nonfossil fuel sources.

The total system electric generation report is based on electric generation from all in-state power plants rated 1 megawatt (MW) or larger and imported utility-scale power generation. It reflects the percentage of a specific resource compared to all power generation, not just retail sales. The total system electric generation report accounts for energy used for water conveyance and pumping, transmission and distribution losses and other uses not captured under RPS.
