Using Tomatoes for Power
March 16, 2016 07:13 AM - American Chemical Society via EurekAlert!

A team of scientists is exploring an unusual source of electricity -- damaged tomatoes that are unsuitable for sale at the grocery store. Their pilot project involves a biological-based fuel cell that uses tomato waste left over from harvests in Florida.

Oregon Kicks Dirty Coal Habit
March 7, 2016 07:41 PM - Kevin Mathews, Care2

Oregon is ready to kick its filthy coal habit, and now it has passed a law to hold itself to this pledge. The Clean Energy and Coal Transition Act blocks the state’s largest power companies from purchasing coal-based electricity by 2030. By taking this important step, the state will effectively double its reliance on renewable energy in the upcoming decades. Moreover, Oregon’s energy should be approximately 80% carbon-free by the year 2040.

The legislation makes Oregon the first state to commit to ditching coal completely. As such, it is easily one of the most progressive energy policies in the United States. Hawaii’s goal to go 100% renewable by 2045 and California’s ambitious 2020 wind and solar goals deserve some credit, too, though.

Oregon’s coal plan is not only exciting because of its unprecedented nature, but because it was a genuinely collaborative effort from all sorts of people in the state. Legislators, citizens, environmental groups, Governor Kate Brown and even the state’s two largest utility companies (Portland General Election and Pacific Power) teamed together to work out new energy goals.

Well-maintained roadways improve fuel efficiency

Most people know that properly inflated tires can improve a vehicle’s fuel efficiency, but did you know that properly maintained roadways can improve fuel efficiency across an entire pavement network?

Scientists unlock key to turning wastewater and sewage into power
February 23, 2016 07:16 AM - Virginia Tech

As renewable energy sources goes, solar rays have historically hogged the limelight. 

But two Virginia Tech researchers have stolen the spotlight from the sun by discovering a way to maximize the amount of electricity that can be generated from the wastewater we flush down the toilet. 

Fukushima impacts hidden from Japanese public
February 21, 2016 07:25 AM - Linda Pentz Gunter, The Ecologist

The Japanese were kept in the dark from the start of the Fukushima disaster about high radiation levels and their dangers to health, writes Linda Pentz Gunter. In order to proclaim the Fukushima area 'safe', the Government increased exposure limits to twenty times the international norm. Soon, many Fukushima refugees will be forced to return home to endure damaging levels of radiation.

Once you enter a radiation controlled area, you aren’t supposed to drink water, let alone eat anything. The idea that somebody is living in a place like that is unimaginable.

As such, one might have expected a recent presentation he gave in the UK within the hallowed halls of the House of Commons, to have focused on Japan's capacity to replace the electricity once generated by its now mainly shuttered nuclear power plants, with renewable energy.

 

Bad air quality is deadly
February 13, 2016 07:18 AM - UNIVERSITY OF BRITISH COLUMBIA via EurekAlert

New research shows that more than 5.5 million people die prematurely every year due to household and outdoor air pollution. More than half of deaths occur in two of the world's fastest growing economies, China and India.

Power plants, industrial manufacturing, vehicle exhaust and burning coal and wood all release small particles into the air that are dangerous to a person's health. New research, presented today at the 2016 annual meeting of the American Association for the Advancement of Science (AAAS), found that despite efforts to limit future emissions, the number of premature deaths linked to air pollution will climb over the next two decades unless more aggressive targets are set.

"Air pollution is the fourth highest risk factor for death globally and by far the leading environmental risk factor for disease," said Michael Brauer, a professor at the University of British Columbia's School of Population and Public Health in Vancouver, Canada. "Reducing air pollution is an incredibly efficient way to improve the health of a population."

Obama Administration's "Clean Power Plan" dealt a setback by the Supreme Court
February 10, 2016 07:03 PM - Jan Lee, Triple Pundit

The Obama administration’s Clean Power Plan suffered a setback on Tuesday when the Supreme Court granted a stay to the program. In a 5-4 decision, the court sided in favor of petitioning states, utilities and coal companies that claimed that the federal government was overreaching its powers when it attempted to establish a national plan to move away from fossil-fuel based power. Requests for the Supreme Court to impose the stay were submitted in January after an appeals court ruled that the plan could proceed while legal challenges were being heard.

The Supreme Court’s ruling is an about-face to the U.S. Court of Appeals for the District of Columbia Circuit, and it comes at a critical time for the Obama administration’s clean energy program, especially in light of the upcoming elections in November. While the administration can appeal the Supreme Court’s order, arguments would not be considered until June and, pending acceptance by the higher court, likely wouldn’t be scheduled until October or later this year. That leaves the fate of the Clean Power Plan in the hands of the upcoming presidency.

Iowa - first in primaries, first in wind power
January 31, 2016 08:25 AM - Zachary Davies Boren / Greenpeace Energydesk, The Ecologist

As presidential contenders gather in Iowa for the beginning of the party selection season, they may have noticed a lot of wind turbines, writes Zachary Davies Boren. And if they have any sense, they will find only nice things to say about them. Wind supplies 30% of the state's power, more than any other US state, and Iowans are all for it. Ted Cruz, mind your words!

Today, there are 12 factories in Iowa that build wind-related parts and materials, and wind supports as many as 7,000 jobs. Furthermore, the steady long-term costs of wind power promise to keep Iowa's electricity prices stable for many years to come.

All eyes are on Iowa, the midwestern state set to kick-off the US presidential election next week with its folksy first-in-the-nation caucus.

How much methane IS leaking at Porter Ranch?
January 15, 2016 07:08 AM - University of California, Davis via ScienceDaily

A UC Davis scientist flying in a pollution-detecting airplane provided the first, and so far only, estimates of methane emissions spewing from the Aliso Canyon Natural Gas Storage Facility in Southern California since the leak began on Oct. 23, 2015.

Those estimates were provided to the California Air Resources Board in November. Pilot and UC Davis project scientist Stephen Conley continues to measure emissions from the still uncontrolled leak, which has displaced thousands of residents in the affluent Porter Ranch neighborhood in northern Los Angeles. On Jan. 6, Gov. Jerry Brown declared a state of emergency in the community.

To date, Conley estimates that the leak has emitted nearly 80,000 tons of methane, or about 1,000 tons per day.

Denmark breaks its own world record in wind energy
January 15, 2016 07:04 AM - EurActiv

Danish wind turbines set a new world record in 2015. Wind power is now counted for 42.1% of the total electricity consumption in Denmark, according to data published on Friday (15 January).

The percentage of wind power in Denmark's overall electricity mix is the highest in the world. Last year, the share was 39.1%, which was a record, according to Energinet, which runs the power grids.
