Seventy-five countries from around the world joined a new political agency dedicated to the acceleration of green energy this January, but several notable nations — including the U.S., Canada, Australia, UK, Japan, and China — were not among them.
If measures aren’t taken immediately to replenish the rapidly shrinking Dead Sea, the very salty body of water in the Middle East will shrivel up within 50 years — and that could pose an environmental calamity, experts have warned.
Barely a month after the U.S. Federal Energy Regulatory Commission (FERC) licensed the nation’s first commercial hydrokinetic power station, Houston-based Hydro Green Energy in January completed installation of the first of two turbines at an existing run-of-river hydropower plant on the Mississippi River for the Minnesota city of Hastings. When the second turbine is installed later this spring, the two hydrokinetic turbines will constitute a floating array that will sit on top of a barge at the Army Corps of Engineers’ Lock & Dam No. 2.
Declining oil prices, supply issues, and dwindling financing may have battered solar energy in recent months, but the industry seems to have sparred well in the research arena. An assortment of institutions separately announced breakthroughs in their quests to boost the efficiency of solar cells. The technological advancements ranged in approach, from the development of an antireflective coating to the formulation of more efficient solar cell materials, but all point to promising possibilities for the industry.
Following a press briefing this morning, President Barack Obama signed new executive orders intended to spur “swift action” on both U.S. economic recovery and American energy independence.
This spring, Xcel Energy, along with state and technology partners, is set to test what the utility says is the first battery capable of storing wind energy. The ability to store energy from renewable generation sources with variable output is key to maximizing the value of renewable power in general and to Xcelâ€™s “smart grid” plans in particular.
The U.S. Environmental Protection Agency (EPA) has described landfills as an "effectively untapped resource" for renewable energy. The agency estimates that landfills are the source of about 12% of global methane emissions. (Methane is about 21 times more powerful as a greenhouse gas than CO2.) The EPA estimated that there were some 1,000 projects around […]
The U.S. power industry’s story in 2009 will be all about change, to borrow a now-familiar theme. Though the new administration’s policy specifics hadn’t been revealed as POWER editors prepared this report, it appears that flat load growth in 2009 will give the new administration a unique opportunity to formulate new energy policy without risking that the lights will go out.
New Zealand’s biggest geothermal energy project in 20 years was officially opened in Kawerau in late November. The state-owned Kawerau Geothermal Station (Figure 5), on the North Island, adds 100 MW to the national grid.
In an effort to more than double its power capacity by 2030, the Brazilian government in November approved construction of a controversial $3.9 billion hydroelectric dam on the Madeira River, in the Amazon. When completed in 2013, the Jirau hydroelectric plant could add 3,300 MW to the country’s already massive 59 GW hydroelectric capacity.
