Global Solar Installations Grew in 2009, Despite Recession

solarEven the biggest global recession since the Great Depression couldn’t stop the solar market from growing in 2009. Many analysts doubted growth would be possible due to the collapse of solar’s largest market in 2008 – Spain. But Solarbuzz.com just released their annual report and the amount of solar installed in 2009 grew Continue reading

US Wind Potential Estimate More Than Triples

wind-farmThis month brought another exciting piece of news for those of us hoping the US will transition to renewable energy in the years ahead. Not only did the US add a record amount of wind capacity in 2009, but new data show that the potential supply of wind power is almost infinite relative to our electricity consumption. The US government agency that deals with renewables, the National Renewable Energy Laboratory (NREL), finally updated their study of onshore wind resources (since the last comprehensive study in 1993). They now estimate that wind power Continue reading

Wind & Solar Poised to Supply New Demand

wind-farmThe recession was supposed to slow down white-hot renewable energy growth. A lack of financing and tax equity was to reduce the wind and solar markets as much as 50% in 2009. Instead, last year brought new records in capacity additions. Wind power in the US grew Continue reading

Solar price falls to new record low, now below 20 cents per kWh

solarMy first week working with the East Coast Greenway Alliance was amazing. And I have some big news to share that helps make my dream of a mobile bicycle/solar existence possible. Bicycles are already cost-effective, but solar has been out of reach to most consumers in the past. It’s price just fell for the 11th straight month, reaching a new record low. Continue reading

Tuvalu commits to 100% clean electricity by 2020

climatechangeRising sea levels are something small island nations like Tuvalu and the Maldives cannot ignore. That is why the Pacific state of Tuvalu just joined the Maldives as a leader in renewable electricity generation. They committed to get all of their electricity from renewables like wind and solar by the year  Continue reading

I’m happy to report that Sustainable Energy Transition (SET) is now getting the bulk of its cell phone’s energy needs from solar power! After 250 blog posts over the past year, it’s nice to look back at this piece of tangible progress for SET’s operations. Thanks to Connect2Earth.org, a green online community supported by WWF, IUCN and Nokia, who gave SET the solar charger – we are further walking our talk. Continue reading

EIA: US emissions diving more than 4% in 2009

climatechange1As I wrote last month would probably happen, the Energy Information Administration (EIA) lowered its estimate for fossil fuel energy demand in 2009, translating into a huge drop in greenhouse gas emissions. Emissions projections for coal, oil, and natural gas were all lowered in its July Short Term Energy Outlook — meaning, by my calculations, that US emissions are expected to fall Continue reading

July solar price survey shows new record low in Europe

solarThe monthly solar price survey by Solarbuzz.com just came out. And it showed retail prices fell another ~1% last month. Prices still have a ways to go before grid parity arrives, but its nice to see the continued progress. Europe is now enjoying another record low solar price for individual modules at Continue reading
