In a joint report issued April 5, a group of California agencies and utilities said that if the Aliso Canyon natural gas storage facility north of Los Angeles cannot be returned to service after a major leak this past winter, repeated gas curtailments could occur this summer, leading to significant loss of generating capacity in Southern […]

One of Russia’s largest solar photovoltaic (PV) facilities has been grid-connected in Abakan, located in the Republic of Khakassia. The Khakass capital in central Russia just north of Mongolia, historically

China has edged past the European Union (EU) in terms of total installed wind capacity, with 145.1 GW to the EU’s 141.6 GW. This means that China, which erected a stunning 30.5 GW in 2015—nearly half of

Vattenfall has dismantled five offshore wind turbines—with a total capacity of 10 MW—at the Yttre Stengrund wind farm in Kalmar Sound, Sweden. The month-long decommissioning project was the first in the

The first of two 500-kW OpenHydro tidal turbines has been successfully deployed at French utility EDF’s much-watched Paimpol-Bréhat tidal project, which is under construction in North Brittany, France. When

Blades are probably the most delicate part of a wind turbine and the most susceptible to accidental damage. Some estimates suggest that greater than 90% of wind turbine blades are damaged to some degree while

If you’re still thinking of drones and robots as more toy than tool, think again. The drones now working in the power sector have gone far beyond remote-control hobbies and now resemble something closer to

In 2000, the world had installed just 1 GW of solar photovoltaic (PV) capacity (in DC terms—see the sidebar, “AC or DC?”), a number that had surged to 39 GW by 2010 and 176 GW in 2014. Fueled by

Although other renewable sources of energy may be growing at a faster rate, more electricity continues to be generated in the U.S. by conventional hydropower than by wind, solar, and geothermal power combined

Geothermal technology, though over a century old, is constantly changing. Developments in mapping techniques have improved exploratory practices. Plant adaptations, such as hybrid technologies and the

Two renewables giants with a hefty global reach are facing debilitating financial crises. SunEdison on the Verge of Bankruptcy California-headquartered solar project developer SunEdison, a company that has 1,000 operational sites worldwide and is staffed by 3,000 employees, is facing a liquidity crisis so dire, the company’s yieldco TerraForm Global warned in a March 29 […]

Edison International, parent company of Southern California Edison (SCE), announced on March 29 that it’s launching a new business unit called Edison Energy that will provide energy consulting services to large energy consumers across the country to help them in identifying and exploiting opportunities to lower energy costs, reduce complexity of energy management, and meet […]

A diverse coalition of major investor-owned utilities, public power authorities, and one of the largest independent power producers, as well as a combination of cities and states, clean energy groups, and environmental groups, filed briefs with the D.C. Circuit Court of Appeals in support of the Environmental Protection Agency’s (EPA’s) Clean Power Plan. The involved […]

The Edison Electric Institute has come under fire for a new communications plan that was intended to depict utilities as more community-minded.

Exelon’s acquisition of Pepco Holdings was approved March 23 as the District of Columbia Public Service Commission approved the deal by a 2-1 vote.

“My sense as I speak to you here today is that nuclear energy is toast,” said New York Times Reporter Eduardo Porter, as he opened a panel discussion titled “Nuclear Energy and the Clean Energy Future” held at the New York University School of Law on March 23. “Despite the challenge from climate change that […]

Over the past week, several states took action on the Clean Power Plan as Senate Majority Leader Mitch McConnell (R-Ky.) urged governors to “wait and see” on the carbon rule, and the Environmental Protection Agency’s (EPA’s) chief defended the rule. McConnell Urges Governors to Halt Compliance Work. In a March 21 letter to the National […]

Whether utilities, technology providers, or independent third-party upstarts are best suited to create a reliable recipe for microgrid development remains an open question.

Although new microgrid configurations, technologies, and business models are still evolving in the U.S., some lessons have been learned in the past few years. Aside from the fact that financing nontraditional/non-campus microgrids is hard, if there’s one overarching lesson, it’s that a microgrid designed to provide only one benefit or rely on only one generation source is unlikely to succeed.

On March 13, three of Germany’s 16 states held regional elections that were largely seen as a referendum on Chancellor Angela Merkel’s increasingly controversial refugee policies as well as the waning importance of energy and climate policies. Perhaps the biggest challenger and winner in this election was the far right, those against both the Energiewende […]

The Oregon Senate passed a bill on March 2 that will require electric companies in the state to eliminate coal-fired resources from their electrical supplies by January 1, 2030. The bill—which passed in the senate by a 17–12 vote—had already been passed by the Oregon House of Representatives (38–20). It now heads to Gov. Kate […]

Utility-scale solar photovoltaic (PV) generation has exploded over the past few years. From nearly nothing in the late 2000s, the U.S. now has more than 10 GW of utility-scale solar PV in operation according to the Energy Information Administration. That figure should continue to grow strongly because of the recent extension of the investment tax […]

Legal battles to stall the 11-GW Belo Monte hydroelectric dam—being built on the Xingu River in Amazon forest for one of the world’s largest power plants—are raging on in Brazil (Figure 1). In January

Germany’s Energiewende (energy transition) was adopted as policy beginning in September 2010, some six months before the disaster at Japan’s Fukushima nuclear plant, and full legislative support was

Utility holding company Xcel Energy, headquartered in Minneapolis and with large electric and gas operations in eight states in the upper Midwest, the Rocky Mountain West, and Texas, has ambitions to be the

New reports released this week see big growth in renewables from the recently extended federal tax credits, but big uncertainty due to the possible end of the Clean Power Plan (CPP). New York-based consulting firm Rhodium Group says investment plans in the power sector will be radically different if the Clean Power Plan doesn’t happen. […]

A proposal put forth by China—and one that it says has received “positive responses” and substantial backing from international groups, including the United Nations—foresees a global smart ultra-high-voltage (UHV) grid that transmits only “clean energy.” The Global Energy Interconnection (GEI) outlined by State Grid Corp. Chairman Zhenya Liu on February 25 at the IHS CERAWeek […]

Despite the unprecedented stay by the Supreme Court, the Environmental Protection Agency’s (EPA’s) Clean Power Plan will withstand legal challenges “based on its merits,” predicted the agency’s head, Gina McCarthy, at the IHS CERAWeek conference in Houston. McCarthy discussed the plan and other recent initiatives to stem greenhouse gas emissions—including recently announced rules to curb […]

The governors of 17 U.S. states on February 16 signed a landmark agreement to cooperate on expanding clean energy, energy efficiency, and modernizing energy infrastructure. The Governors’ Accord For A New Energy Future makes the case that “new energy solutions” can “provide more durable and resilient infrastructure, and enable economic growth, while protecting the health […]
