ast month, General Electric (GE) consulting presented the results of a U.S. National Renewable Energy Laboratory (NREL) sponsored study testing if wind turbines can be controlled to manage the stability of the electric grid. The authors found that wind turbines might actually be a valuable tool for controlling and stabilizing the grid in the future, disputing the conventional notion that wind energy doesn’t play well with the grid. To understand the source of this counterintuitive result—and its implications—let’s review the key aspect of power grid control at play here: frequency regulation.
Acting air chief Janet McCabe said the agency will accept comments through Dec. 1, adding to one of the longest comment periods ever for a rulemaking. EPA unveiled the rule proposal June 2. “We hope that additional time will give those entities wishing to submit comments the time they need to engage with us, ask questions, and ultimately provide input that will help ensure that in the end this plan is practical, flexible and achievable,” she said.
Rhode Island will have a major role to play in the offshore wind industry, even though a developer chose to use a Massachusetts port to build a large wind farm, Governor Lincoln Chafee said Monday. Rhode Island officials had hoped that Cape Wind would use New Bedford and Rhode Island’s Quonset Point for the staging and construction of a proposed 130-turbine wind farm off the coast of Cape Cod, bringing jobs and economic activity to both states. Cape Wind announced Friday that it had signed a lease agreement with Massachusetts.
A new study that evaluated bird mortalities at wind farms across North America found that collisions with wind-turbine blades annually kill less than 1 percent of the smallest and most common birds on the continent, a conclusion that the study’s sponsors say points to the need to focus bird conservation on climate change, loss of habitat and other more significant threats.
While comprehensive tax reform has been on Congress’ back burner for most of the year, a Senate hearing this week could shed some additional light on what an eventual overhaul of the tax code would mean for oil companies, renewable energy developers and others in the energy industry.
Green energy programs have expanded in blue states as well as deeply conservative ones like Texas and Mississippi in recent years, according to a study released yesterday by Stanford University and the Hoover Institution. “Many states, from all parts of the country and from all political perspectives, are taking steps to promote energy efficiency and renewable energy,” the report said. “Put simply, both red states and blue states are turning green, whether measured in dollar-savings or environmental benefit,” it added.
A state energy board gave conditional approval Friday to a $140 million wind farm that would rise south of Blue Hill in south-central Nebraska.
Financed by NextEra Energy Resources, the nation’s largest wind developer, the project would produce about $800,000 a year in lease payments to 35 landowners and about $864,000 a year in local taxes. That would represent a 7 percent increase in overall tax revenue for Webster County, according to David Levy, an Omaha attorney who represents Florida-based NextEra.
Of all the developed nations, few have pushed harder than Germany to find a solution to global warming. And towering symbols of that drive are appearing in the middle of the North Sea. They are wind turbines, standing as far as 60 miles from the mainland, stretching as high as 60-story buildings and costing up to $30 million apiece. On some of these giant machines, a single blade roughly equals the wingspan of the largest airliner in the sky, the Airbus A380. By year’s end, scores of new turbines will be sending low-emission electricity to German cities hundreds of miles to the south.
Google Inc., the Internet technology giant and green energy investor, will provide $145 million in equity funding to help construct one of the world’s largest brownfield-to-renewable energy sites. The 82-megawatt Regulus solar project in Kern County, Calif., will cover a 737-acre former oil and gas field with nearly a quarter-million solar photovoltaic modules, whose electricity output will be sufficient to power roughly 10,000 California homes.
Some states throughout the U.S. have implemented various policies to encourage renewables and energy efficiency that could be adopted by neighboring states to improve local economies, provide energy security and reduce emissions, according to a new study. In addition, the report says these innovative policies could be particularly valuable as states develop plans to meet the U.S. Environmental Protection Agency’s (EPA) pending rules to cut power plant emissions. One effective clean energy policy, the study points out, is a renewable portfolio standard (RPS).
