Global environmental challenges
A professor at the University of Delaware has patented a vehicle-to-grid (V2G) technology for parked electric vehicles to return power to the grid and teamed up with NRG Energy to commercialize it.
Professor Willett Kempton, who has been testing V2G technology that lessens the load on natural gas plants, told the New York Times utilities would not be interested in buying electricity from individual cars but from groups of perhaps 100 vehicles.
The idea is not without its critics.
“The only way this will take off is for users to have a financial incentive to allow the power company to do this, i.e. the power price during peak demand must be so high that it’s cheaper to deplete your EV battery rather than draw from the grid,” writes hackertourist on listserv slashdot.
Ancillary services could fetch $3,000 a year for EV owners, CNET Green Tech reported the Federal Energy Regulatory Commission chairman saying last year.
Environmental groups and the oil industry are battling on a new front in the long-running public relations war over Canada’s oil sands. This one concerns claims that crude wrung from the massive deposits is more corrosive to pipelines and hence presents a bigger risk of oil spills.
Green groups say the crude eats away at the inside of pipelines much more quickly than is the case with conventional oil and the industry says it doesn’t.

The environment hasn't been spared in India's headlong rush towards development and consumerism. With it came mounds of garbage, piles of waste that had nowhere to go, industrial pollutants that were fed straight back into the rivers and lakes that supply drinking water to millions. Walking around the streets of any town in India, you don't get the feeling that care for the environment is on the top of anyone's list of priorities.
So it was with a little skepticism that I read about a school which claimed to be completely environmentally friendly. I made a plan to travel to Pune, about 190km (118 miles) from Mumbai, to take a look at the Aman Setu school, which means "bridge to peace". They claimed fantastic things - the buildings were environmentally friendly made entirely out of recycled and natural bits and pieces - they had their own vegetable garden for children - kids were allowed to run around barefoot.
OK, OK, enough fun with acronyms. HIPPO and ICE-T are flying climate laboratories, one in a Gulfstream V jet, the other in a refurbished C-130 military cargo plane.

It was Saturday, May 21, and I was returning from a tour with nine friends. We had spent 15 hours climbing a 1420 metre (yard) high peak named Midfellstindur near Iceland's Skaftafell national park. While driving back along route 1 from Skaftafell towards our hotel, the organizer of the trip Hans Kristjansson said "This is a strange cloud just above the glacier".
As a hang glider and ultralight pilot I knew right away that this was no ordinary cloud and said to Hans: "My friend, this is not a ordinary cloud but the start of an eruption". We stopped the car and I tried to use well the last seven frames that I had on my memory card in my Canon D300 DSLR camera. I took seven frames in about 20 minutes. I always take my photos in RAW format to be able to post-process them. It paid off this time. The pictures were taken at N 63° 56.712 W 17° 23.729.
Andy Wales, head of sustainable development at global brewer SABMiller, maintains it can happen. The maker of Miller beer — and 20 other brands, from Aguila in Colombia to Zolotaya Bochka Klassicheskoye in Russia — likes the environmental angle, but the main impetus is to ensure production of their products in what is a highly variable business from location to location.
“Water is obviously a critical part of high quality beer,” Wales said by telephone from London. One important part of this equation is figuring out how to use less water and still make good beer.
A word has entered the language — at least, the language of environmental concern — that may be ready for prime-time. That word is Anthropocene. It’s the epoch we’re apparently living in, roughly translated as the Age of Man. The theory behind the name is that human beings have made such an impact on Earth’s geology that we should have an era named for us that differentiates this time from the tired old Holocene period.
Holocene means “entirely new,” but it’s been some 10,000 years since it started. Scientists and others meeting in London figure it may be time to move on.
If you took all the cows in the United States and figured out how much greenhouse gas they emit, would you be able to sue all the farmers who own them?
That interesting legal question came from Justice Antonin Scalia during Supreme Court oral arguments about whether an environmental case against five big U.S. power companies can go forward.

The ongoing crisis at the Fukushima Daiichi nuclear plant in north-eastern Japan, seriously damaged by a March 11 earthquake and tsunami, has led to anti-nuclear protests in several countries and forced governments to rethink their energy policies.
The UK currently has 10 nuclear power stations, representing 18 percent of the country’s energy supply according to Energy UK. Should British Prime Minister David Cameron, like German Chancellor Angela Merkel, reverse his position on the safety of nuclear power?
