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
As 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
Solar module prices are falling so fast that solar may be able to cost-effectively compete with fossil fuels within a matter of months. The latest bit of news confirming astounding price drops was from China’s LDK Solar. LDK is a producer of the main component of solar modules (wafers). While their second quarter guidance showed a boost in shipments, it also lowered their revenue expectations, translating into a cost per watt of Continue reading
Last night, the US House of Representatives passed climate legislation to get greenhouse gas emissions falling to 83% below 2005 levels in 2050. This step is huge, and needs to be followed by a similar bill passing the Senate in the weeks ahead to get the President’s signature and become law. Here are some details from the Solar Energy Industries Association: Continue reading
The world is watching as US federal leaders vote on climate legislation that would put US emissions on a downward trajectory in the decades ahead. While some organizations such as Greenpeace do not support the Waxman-Markey bill due to its large offsets provisions and its free allocation of many emission permits, most environmental organizations are supporting it and hoping to improve it in the years ahead. You can be a part of history! Here is an action alert from Continue reading
The US Energy Information Agency (EIA) has further lowered its emissions projection for 2009 this month, as I said in May was likely. Lower coal consumption drives the reduction, based on the drop in industrial demand for fuel and the substitution by natural gas for coal for Continue reading
The first quarter has been a rough one for most solar companies. Aside from First Solar whose profits tripled, most solar companies reported large decreases in their profits and, most likely, losses. But the last two reports (from Trina Solar and China Sunergy) paint the picture of a potential return to profitability in the Continue reading
2006 Chapel Hill/Carrboro Blue Bikes Launch
During the first quarter of 2009, more bicycles were sold in the US than cars and trucks. While the Great Recession is hurting bike sales, they didn’t fall as fast as automobiles. Over 2.55 million bicycle purchases were made, compared to less than 2.4 million cars and trucks that left Continue reading
The US Energy Information Administration (EIA) released its monthly Short Term Energy Outlook today. And their projection for 2009 US carbon dioxide emissions from energy fell even further than last month’s. The drop was led by Continue reading
The economics of solar power are changing rapidly. And if the Prometheus Institute for Sustainable Development (PI) is right that solar module prices will fall more than 50% by 2012, grid parity will be achieved across many parts of the US. Solar electricity currently carries a price tag that is higher than Continue reading
