Sunny Forecast for Solar Power
April 13, 2012 07:16 AM - Editor, Sierra Club Green Home
The American solar industry more than doubled in megawatts last year, from 887 megawatts installed in 2010 to 1,855 megawatts installed in 2011. This growth represents enough solar energy to power over 350,000 homes! 2011 also marks the first time the U.S. solar market has topped one gigawatt (1,000 MW) in a single year. Many factors contributed to this growth. The cost of installing solar panels fell 20 percent last year due to lower component costs and improved installation efficiency. Expanded financing options and a shift toward larger systems nationwide also made solar more affordable. In addition the 1603 Treasury Program, which offered rebates for businesses that installed solar panels, ended Dec. 31, 2011. This looming deadline drove developers to commission projects before the end of the year.
Shale Oil Impact in Russia
April 12, 2012 04:23 PM - Andy Soos, ENN
Shale oil, known also as kerogen oil or oil-shale oil, is an unconventional oil produced from oil shale by pyrolysis, hydrogenation, or thermal dissolution. These processes convert the organic matter within the rock (kerogen) into synthetic oil and gas. The resulting oil can be used immediately as a fuel or upgraded to meet refinery feedstock specifications by adding hydrogen and removing impurities such as sulfur and nitrogen. The refined products can be used for the same purposes as those derived from crude oil. The largest known reserves are in the US. Russian Prime Minister Vladimir Putin has urged his country's gas industry to rise to the challenge of shale gas as the United States and some European countries forge ahead with developing the controversial energy source. US shale gas production may seriously restructure supply and demand in the global hydrocarbons market, Putin said yesterday in his final address to the Russian Duma before he takes over as president on 7 May.
Sales of Volt and Hybrids Surge in March
April 12, 2012 07:06 AM - Phil Covington, Triple Pundit
March turned out to be a big month for auto sales in the United States. Reuters reported that total vehicle sales were up 13 percent for the month, ending the best quarter in terms of total sales since 2008. The industry sees this as a sign of general economic recovery, but with high average gas prices prevailing at the pumps, hybrid cars and plug-in vehicles enjoyed a strong month, indicating fuel economy matters to many when making new car choices.
Study: Allowing More Salmon to Spawn Creates a Win-Win for Humans and Ecosystems
April 11, 2012 09:58 AM - David A Gabel, ENN
Salmon spend most of their lives in the ocean, but return to their birthplaces in freshwater streams to spawn the next generation. These annual migrations up and down the inland rivers are well known and play a significant role in the ecosystem, particularly in the Pacific Northwest. However, there is a concern that humans are harvesting too many salmon, not allowing enough to return upstream to reproduce. This leaves little for the species which depend on the salmon runs such as grizzly bears. A new research study suggests that more Pacific salmon should be allowed to spawn in coastal streams, which would create a win-win for humans and the natural environment.
Do protected areas for wildlife really work?
April 11, 2012 07:14 AM - Eifion Rees, The Ecologist
Can national parks and marine protected areas safeguard endangered wildlife against the growing pressures of population growth and climate change? Designated a national park in 1778 but safeguarded unofficially since the 13th century, the world's oldest protected area is Mongolia’s sacred Bogd Khan Mountain, overlooking Ulan Bator. The Emperor of Manchur’s 18th-century edict was designed to prevent mortals from desecrating the realms of the divine. Building was restricted, logging and hunting banned.
Bounty Offered on 'Fishzilla'
April 9, 2012 08:23 AM - Kieran Mulvaney, Discovery News
If Stephen King were to write a novel about a terrifying, monstrous fish, he might create something not unlike the snakehead. Its large mouth is filled with razor-sharp teeth. It is a voracious predator, feasting on anything from worms to small mammals... But dead is the only way fishery officials in the United States want to see the northern snakehead.
In Dubai, Camels may work to control Mangrove trees
April 8, 2012 02:07 PM - Tafline Laylin, Green Prophet
Too many mangroves is not a good thing — at least not at the Ras Al Khor Wildlife Sanctuary in Dubai, where they were introduced in 1990. So an ecologist at Dubai’s Wildlife Protection office has proposed using camels to trim back the excess canopies that have buried wader feeding areas. Kevin Hyland told The National that camels used to have access to the sanctuary before it was fenced off in 2002, and that reintroducing them would help restore the site’s sensitive ecology without disrupting bird life. Hyland emphasizes that the camels would be introduced as part of a careful management program, and that they will not be left to run amok. "The key phrase in the whole proposal is 'managed camel grazing,'" the ecologist told the paper. "It's not, 'let's just chuck in 100 camels, because we don't want to destroy the mangrove canopy."
Spring has Sprung, it's getting warmer
April 8, 2012 07:27 AM - NPR
Across the country, more than 7,700 daily temperature records were broken last month, on the heels of the fourth warmest winter on record. While it might be time to lie on a blanket in the park, climate scientists are worried. They say all these sunny days are actually an extreme weather event, one with local and global implications. In Iowa, March was so hot — a record-breaking 84 degrees — that some crops there, like oats, are now running way ahead of schedule.
The Arctic is getting more militarized
April 7, 2012 08:26 AM - Euractiv
Norwegian and Russian energy relations might be put at risk when it comes to the exploration and acquisition of untapped energy resources in the Arctic with both countries increasing their militarisation in the area, according toStratfor an Austin, Texas-based global intelligence company providing geopolitical analysis and commentary. "Norwegian Defence Minister Espen Barth Eide indicated March 28 that the Norwegian army 2nd Battalion would be renamed the "Arctic Battalion" and equipped to patrol the country's Arctic territory. The battalion, a mechanised infantry unit based in the northern county of Troms, will be supplied with snowmobiles and other light vehicles for the task.
Classes Make Bicycling in Los Angeles Easier
April 5, 2012 09:03 AM - Courtney Hayden, Sierra Club Green Home
It is 9 am and traffic is crawling on the 101 freeway...and on the 405, and on the 118. Sunshine pours through the windshield, turning your mind to thoughts of walking through the Santa Monica Mountains and biking down to the beach. Minutes are ticking by, marked only by the occasional horn honking loudly behind you. As for the gas you put in the car earlier? It is working its way towards "E." There is a way to reduce your fossil fuels consumption and make daily commutes enjoyable: bicycling. And a new organization is here to help make biking in Los Angeles easier. If you are new to biking or if the thought of peddling down crowded LA streets intimidates you, Sustainable Streets offers free safety courses to help ease your transition into biking. Courses are available in Burbank, West Hollywood, and along the beach in Santa Monica. Classes start with four hours in the classroom, followed by one hour on a simulated road, and then almost five hours of actual street riding.
