Renewable energy capacity increases, nuclear declines
September 30, 2014 05:03 PM - Editor, Worldwatch Institute
Advocates of nuclear energy have long been predicting its renaissance, yet this mode of producing electricity has been stalled for years. Renewable energy, by contrast, continues to expand rapidly, even if it still has a long way to go to catch up with fossil fuel power plants, writes Worldwatch Institute Senior Researcher Michael Renner in the Institute’s latest Vital Signs Online analysis (bit.ly/NuclearRE). Nuclear energy’s share of global power production has declined steadily from a peak of 17.6 percent in 1996 to 10.8 percent in 2013. Renewables increased their share from 18.7 percent in 2000 to 22.7 percent in 2012.
Carbon Capture Technology and Climate Action
September 22, 2014 11:39 AM - David Biello from Yale Environment360
Some scientists and analysts are touting carbon capture and storage as a necessary tool for avoiding catastrophic climate change. But critics of the technology regard it as simply another way of perpetuating a reliance on fossil fuels. For more than 40 years, companies have been drilling for carbon dioxide in southwestern Colorado. Time and geology had conspired to trap an enormous bubble of CO2 that drillers tapped, and a pipeline was built to carry the greenhouse gas all the way to the oil fields of west Texas. When scoured with the CO2, these aged wells gush forth more oil, and much of the CO2 stays permanently trapped in its new home underneath Texas.
Electric vehicles getting even "Greener"
September 16, 2014 03:01 PM - Union of Concerned Scientists
Sixty percent of Americans now live in regions where electric vehicles (EVs) produce fewer heat-trapping global warming emissions per mile than the most efficient hybrids, according to an updated analysis from the Union of Concerned Scientists (UCS). In 2012, that number was just 45 percent. "Electric vehicles are doing more and more to fulfill their technological promise," said Don Anair, research director for UCS's Clean Vehicles Program. "If we want to reduce transportation pollution and oil use, a big part of the answer is to be like Bob Dylan and go electric."
Japan: 'solar islands' replace nuclear power
September 15, 2014 08:41 AM - Jon Major, The Ecologist
As Japan seeks to end reliance on nuclear power, one of the answers is floating 'solar islands', writes Jon Major. A 70MW solar island opened last year, and two additional plants have just been announced. Two companies in Japan recently announced they are to begin building two large solar power islands that will float on reservoirs.
Disc or Download: A Virtual Energy-Savings Debate
September 11, 2014 11:20 AM - Winfield Winter, ENN
One of the best ways to spark an energy revolution is through the younger generation — and nothing quite speaks their language like video games. But this issue has less to do with the content of these addictive games and more with how the younger generation consumes them. Fantasy and adventure, sci-fi and first-person shooters, strategy and racing — video games today comes in all types of genres with thousands of add-ons and customizable features to make each story a virtual reality. And with all of these choices comes two more: buy a copy of the video game on a disc or download the video game straight from the console?
Hot and Cold Freezers
September 10, 2014 09:25 AM - Bill DiBenedetto, Triple Pundit
The freezers being tested in Central Park operate free of electricity — vendors can even charge their own mobile devices by plugging them into outlets attached to the freezer units. It seems fitting that Unilever, the world's largest producer of ice cream, is rolling out the world's first solar freezers in Central Park to keep those Popsicles, Good Humor or Magnum-brand bars cold while at the same time putting no strain on the environment.
Block Island wind farm gets final approvals
September 5, 2014 06:00 PM - ecoRI News staff
Deepwater Wind has received the final federal approval needed to build the Block Island Wind Farm — a project that remains on-track to be the nation’s first offshore wind farm. The project’s lead federal permitting agency, the Army Corps of Engineers, granted its approval Sept. 5. With the Corps’ permit, the Block Island Wind Farm has now been completely reviewed, and approved, by nine state and federal agencies: Army Corps of Engineers, Federal Aviation Administration, U.S. Fish & Wildlife Service, National Oceanic and Atmospheric Administration, Environmental Protection Agency, Coast Guard, Rhode Island Coastal Resources Management Council, Rhode Island Department of Environmental Management and the Rhode Island State Historic Preservation Office.
Study Suggests More Research before Fracking Continues
August 29, 2014 07:22 AM - ClickGreen Staff, ClickGreen
An independent report on fracking has recommended a temporary moratorium on the controversial process and says that communities should give permission before it can proceed. The interdisciplinary expert panel set up by the Nova Scotia regional government says the science of fracking is relatively unknown and therefore its introduction should be delayed in the Province until the science and its environmental effects are better understood.
A Fukushima-Sized Problem
August 27, 2014 11:45 AM - Karl Grossman, The Ecologist
A newly-exposed report by Diablo Canyon's lead nuclear inspector shows that the twin reactors are unsafe, writes Karl Grossman. An earthquake on nearby geological faults could trigger a Fukushima-scale accident causing 10,000 early fatalities. The owner's response? Apply to extend the site's operation for another 20 years. As aftershocks of the 6.0 Napa earthquake that occurred Sunday in California continued, the Associated Press revealed a secret government report pointing to major earthquake vulnerabilities at the Diablo Canyon nuclear plants which are a little more than 200 miles away and sitting amid a webwork of earthquake faults.
Dams vs. Rivers
August 27, 2014 08:40 AM - Editor, The Ecologist
A new 'State of the World's Rivers' database shows how the world's rivers have been impoverished by dams and their ecosystems devastated - and provides a valuable resource to help save river basins that remain in good health. International Rivers has launched 'The State of the World's Rivers', an interactive online database that illustrates the role that dams have played in impoverishing the health of the world's river basins.
