  • NREL Finds Greater Cycling from Renewable Penetration Does Not Significantly Increase Emissions

    Much attention has been devoted recently to the increased cycling that is necessary in fossil plants as more renewable capacity is added to the grid, but data on the precise impacts has been slight. Now, a new study from the National Renewable Energy Laboratory (NREL) aims to correct that. The key findings: While cycling would increase […]

  • EPA Proposes Revised Carbon Standards for New Power Plants (UPDATED)

    The Environmental Protection Agency (EPA) on Friday issued a revised proposal to curb carbon emissions from new power plants that sets separate standards for new gas-fired and coal-fired power plants. The agency also revealed it is developing new carbon standards for existing power plants. Separate Standards for Coal and Gas and Forthcoming Existing Plant Standards […]

  • California Set to Enact Major Revisions to Utility Ratemaking Structure

    Ending a tumultuous battle over the future of electricity in the state, the California Legislature passed a wide-ranging revision of its ratemaking structure last week. Despite the contentious subject, the bill, AB 327, was approved by a broad bipartisan majority and garnered widespread support from the state’s three investor-owned utilities, the residential solar industry, and […]

  • NREL Report: Cheaper Chinese Solar Panels Not Due to Low-Cost Labor, Subsidies

    China’s historical solar photovoltaic (PV) price advantage is driven by economies of scale and supply chain development—not direct government subsidies or low labor costs, as is the prevailing belief—suggests a new study from the Department of Energy’s National Renewable Energy Laboratory (NREL) and the Massachusetts Institute of Technology (MIT). The study recently published in the […]

  • Groups: EIA Renewable Energy Data Doesn’t Reflect “Real World”

    Nearly 100 renewable energy and environmental groups and businesses have asked the Energy Information Administration (EIA) to reevaluate renewable energy forecasts, alleging the agency’s projections don’t reflect “the current status and recent, real-world growth rates of renewables.” In a Sept. 10 letter to EIA Administrator Adam Sieminski, the coalition says the agency’s estimates in past […]

  • Renewable Intermittency Is Real

    If you’ve been paying attention to energy issues in the media lately, you may have encountered a curious narrative that’s starting to gain traction among supporters of renewable energy. Namely, that the core problem with wind and solar photovoltaic (PV) generation, which is matching moment-to-moment demand with the intermittency wind and sunlight, isn’t really a […]

  • The World’s Most Colossal Offshore Wind Farm Opens

    The $2.9 billion London Array—the world’s biggest offshore wind farm—opened this July in the Outer Thames Estuary about 12 miles off the coasts of Kent and Essex. The 175-turbine installation is arranged

  • China’s Second- and Third-Largest Mega-Dams Mark Operational Milestones

    China hit two of its most significant hydroelectric milestones in recent months: Initial operation of the 13.86-GW Xiluodu project—the country’s second-largest hydropower project after the 22.5-GW Three

  • NREL: Cost Gap for Wind and Solar Could Diminish without Subsidies in West by 2025

    A new report from the National Renewable Energy Laboratory (NREL) suggests wind and solar generation could become cost-effective without federal subsidies if they are sited in the most productive locations. “It is too early to say how strong the post-2025 market for renewables will be or whether it will be primarily market-driven or policy-driven. In […]

  • Tres Amigas Proposes Buried HVDC Line

    New Mexico could host the nation’s first buried long-distance high voltage direct current (HVDC) electric transmission network if an ambitious project proposed by Tres Amigas LLC gains traction. The merchant transmission entity whose mission it is to unite the nation’s three power grids to achieve its renewable energy goals unveiled the 2,000-MW New Mexico Express […]

  • Reports: Future Coal and Nuclear Prone to Market Forces, Gas Expansion

    Two federally sponsored reports submitted to the Eastern Interconnection States’ Planning Council (EISPC) suggest that the rapid expansion of natural gas could force the closure of between 35 GW and 60 GW of U.S. coal power capacity over the next five years and weaken market forces that now bolster existing nuclear plants. An Energy Department–funded […]

  • BOEM Finds No Significant Impact for First Proposed U.S. Ocean Current Energy Test Site

    The first ever lease application received to test ocean current energy equipment in the U.S. has been greenlighted by the Bureau of Ocean Energy Management (BOEM). The Department of the Interior agency that oversees energy activities on the Outer Continental Shelf on Monday announced availability of a revised environmental assessment (EA) and its finding of […]

  • RWE to Close 3.1 GW of Conventional Generation Across Europe on Profit Woes

    Europe’s third-largest power provider on Tuesday announced it would take offline 3.1 GW of natural gas and coal power plants in Germany and the Netherlands, citing a “continuing boom in solar energy.” Echoing several European utilities, Germany-based RWE has underscored the declining profitability of fossil fuel–fired plants that it says is pegged to fundamental changes […]

  • DOE: Wind Leads New U.S. Generation Additions in 2012

    Wind power installations in 2012 represented a 43% majority of all new power capacity additions in the U.S. and accounted for $25 billion in U.S. investment, two new reports from the Department of Energy show. The Lawrence Berkeley National Laboratory (LBNL) released the “2012 Wind Technologies Market Report,” which details the latest trends in the […]

  • The Spotlight on a Mexican Success Story

    Energy demand in Mexico, according to the Secretary of Energy (SENER), will increase by approximately 4% each year for the next ten years, and with it the potential for private sector growth in the industry. Download the report.
