Annual reports analyzing the wind energy industry released today by the Energy Department show continued rapid growth in wind power installations in 2015, demonstrating market resilience and underscoring the vitality of the U.S. wind energy market on a global scale. Wind power provides clean energy to homes and businesses, reduces climate-changing carbon pollution, and boosts America’s economic competitiveness. The U.S. wind power market remained strong in 2015 thanks to continued low prices, more-efficient wind turbines, and fast-growing demand nationwide.
“Sustained low wind energy prices and solid growth in installations helped make 2015 one of the best years for our nation’s renewable energy market,” said Acting Assistant Secretary for Energy Efficiency and Renewable Energy David Friedman. “These reports show that with more American homes and businesses powered by wind energy than ever before, our nation’s clean energy future is bright.”
According to the 2015 Wind Technologies Market Report released today by the Energy Department and its Lawrence Berkeley National Laboratory, the United States ranks second in the world for wind power capacity and remains first in the world for electricity generated from wind power. Total installed wind power capacity from turbines rated at more than 100 kilowatts in the United States grew at an impressive rate of 12% in 2015 and stands at nearly 74 gigawatts, meeting an estimated 5.6% of U.S. end-use electricity demand in an average year. The nearly 8.6 gigawatts of capacity installed during 2015—representing more new deployment than any other electricity source—is a 77% increase over total installations in 2014. More than 4,300 utility-scale wind turbines were installed across 64 projects in 20 states in 2015, bringing the total fleet to more than 48,500 operating utility-scale wind turbines in 40 states and Puerto Rico.
The report also finds that wind energy continues to be sold at attractive prices through power purchase agreements, making this renewable energy source fully cost-competitive with traditional power sources in many parts of the United States. In fact, wind generated a total of more than 190 million megawatt hours of electricity in 2015—enough to power over 19 million average U.S. homes and saving the equivalent of more than 130 million metric tons of carbon dioxide in 2015.
Newer, larger, and more robust wind turbines are enabling significantly greater wind project productivity among new wind projects across the country. The report also illustrates how the U.S. wind industry has positively impacted the American workforce by currently supporting 88,000 jobs related to development, siting, manufacturing, transportation, and other industries—an increase of 15,000 jobs in 2015.
Compared with traditional, centralized power plants, distributed wind energy installations supply power directly to homes, farms, businesses, and communities. In total, U.S. wind turbines in distributed applications reached a cumulative installed capacity of more than 934 megawatts—enough to power more than 142,000 average American homes—according to the 2015 Distributed Wind Market Report, also released today by the Energy Department and its Pacific Northwest National Laboratory. This capacity comes from roughly 75,000 turbines installed across all 50 states, the District of Columbia, Puerto Rico, and the U.S. Virgin Islands. Turbines used in these applications can range in size from a few hundred watts to several megawatts, and can help power remote, off-grid homes and farms, as well as local schools and manufacturing facilities.
In 2015, U.S. manufacturers dominated domestic sales of small wind turbines (up through 100 kilowatts) and doubled exports to 21.5 megawatts. Between 2012 and 2015, U.S.-based small wind turbine manufacturers accounted for more than $310 million in small wind turbine export sales.
According to the U.S. Energy Information Administration, American wind energy more than doubled from about 95 million megawatt hours generated in 2010 to more than 190 million megawatt hours in 2015. Hydropower has historically been the largest renewable electricity source, but capacity in wind, solar, and other non-hydro renewable sources has grown so much in recent years that non-hydro renewable electricity generation exceeded hydropower generation for the second straight year in 2015. Lower-than-normal levels of rain and snow have also contributed to lower hydropower generation in recent years.

A plan to shutter the last remaining nuclear power plant in California and replace it with renewable energy is being heralded widely as “a clear blueprint for fighting climate change,” which environmentalists hope will serve as “a model” for the nation.
“The end of an atomic era,” is how the San Francisco Chronicle described the announcement, made Tuesday by Pacific Gas & Electric (PG&E), which operates the aging Diablo Canyon power plant situated on California’s central coast.
The joint proposal (pdf), drafted by the utility company along with a number of labor and environmental groups, states: “PG&E in consultation with the Parties has concluded that the most effective and efficient path forward for achieving California’s SB350 policy goal for deep reductions of [greenhouse gas (GHG)] emissions is to retire Diablo Canyon at the close of its current operating license period and replace it with a portfolio of GHG free resources.”
The licenses are currently set to expire in 2024 and 2025 and under the deal the utility will replace that power source with renewable energy, energy efficiency, and energy storage. The agreement also contains provisions to protect the plant’s workforce, as well as the economy of the local San Luis Obispo community. PG&E further commits to derive 55 percent of the electricity produced across its entire fleet from clean, renewable sources by 2031.
“This is an historic agreement,” said Erich Pica, president of Friends of the Earth, which helped draft the plan, along with Natural Resources Defense Council, Environment California, International Brotherhood of Electrical Workers Local 1245, Coalition of California Utility Employees, and Alliance for Nuclear Responsibility.
Pica continues, “It sets a date for the certain end of nuclear power in California and assures replacement with clean, safe, cost-competitive, renewable energy, energy efficiency and energy storage. It lays out an effective roadmap for a nuclear phase-out in the world’s sixth largest economy, while assuring a green energy replacement plan to make California a global leader in fighting climate change.”
Rhea Suh, president of NRDC, said the joint agreement is “a tribute to what can be accomplished when we rally together around a common goal.”
“What’s more,” Suh added, “this plan is a model that can be replicated around the country, where nearly 100 nuclear reactors will retire in the coming decades, and around the world.”
“For years,” she continued, “some have claimed that we can’t fight climate change without nuclear power, because shutting down nuclear plants would mean burning more fossil fuels to generate replacement electricity. That’s wrong, of course, and now we have the proof.”
“Today’s agreement is a good example of how we can replace dirty energy with clean when we set our minds to it,” agreed Rob Sargent, Energy Program director at Environment America. “It’s this kind of commitment that will put us on a path to 100 percent renewable energy.”
Tuesday’s announcement follows years of public opposition to the plant, which sits in an earthquake red zone near four prominent fault lines—one of which runs just 2,000 feet from the two reactors. As anti-nuclear activist Harvey Wasserman recently noted, “[m]ore protestors have been arrested at Diablo than any other American nuke.”
In addition to the risks posed by potential earthquake damage, Wasserman wrote, “Diablo dumps daily some 2.5 billion gallons of super-heated water into the ocean, killing vast quantities of marine life and worsening the global climate crisis. The project’s chemical runoff infamously killed millions of abalone years before it operated.”
The detailed phase out proposal will now go to the California Public Utility Commission and on to federal regulators for approval.
According to the Chronicle, the decommissioning process is estimated to cost $3.8 billion, $2.6 million of which PG&E has already collected in an earmarked fund. The utility is reportedly seeking to raise electricity rates by roughly 51 cents per month to make up the shortfall.
Voicing his support for the plan, California lieutenant governor Gavin Newsom, said: “The idea that the economics— from PG&E’s perspective—work for renewables is a pretty profound moment in energy policy. We’ve been asserting it for decades. And here you have a major utility acknowledging a low-carbon, green future.”

On the heels of clean fuel milestones in Germany and Portugal , a new report finds that the renewable energy industry employed over 8.1 million people worldwide in 2015.
According to the International Renewable Energy Agency’s (IRENA) annual review, that figure marks a 5% increase from the previous year. China led the pack, accounting for 3.5 million jobs. Brazil and U.S. ranked second and third, respectively, for the highest number of renewable energy jobs.
The solar photovoltaic (PV) sector shot up 11% and accounted for biggest number of jobs at 2.8 million globally.
In the U.S. alone, solar grew nearly 22%. That’s “12 times faster than job creation in the US economy—surpassing jobs in oil and gas,” the report states. The other country seeing growth in solar was Japan, which notched a 28% increase in solar PV employment in 2014.
Wind saw “a record year” in employment, the report states. Wind energy employment in the U.S. grew 21%; worldwide it grew 5%. At the same time, oil and gas extraction jobs fell by 18 percent in the U.S.
“This increase is being driven by declining renewable energy technology costs and enabling policy frameworks,” stated IRENA Director-General Adnan Z. Amin. “We expect this trend to continue as the business case for renewables strengthens and as countries move to achieve their climate targets agreed in Paris,” he added, referring to the UN climate deal sealed at the end of 2015.
Mark Kenber, CEO of The Climate Group, an organization that advocates for reining in carbon emissions, added, “A clean revolution is key to growth, investment, jobs, health, security: there is no high-carbon prosperous future.”
The new review follows a separate brief released (pdf) by IRENA on “the true costs of of fossil fuels,” which found that doubling the global share of renewables by 2030 would save not only $4.2 trillion annually but also as many as 4 million lives.
