A cleantech start-up out of the UK, Naked Energy, has created a technology that’s a little over my head, but that looks quite cool. Basically, one of the key challenges of solar photovoltaics (PV) is that their efficiency drops if they get too hot. Naked Energy, in response, has … [continued]
In their excellent interactive graphic, Bloomberg Energy Finance calls solar grid parity (when electricity from solar costs less than grid power) the “golden goal.” It’s an excellent illustration of how the right energy policy can help a nation go gold on solar or wallow in metallurgical obscurity. In the case of … [continued]
According to a new report from the U.S. Department of Agriculture, airports could become a significant source of biomass for biofuels. The key takeaway from the report, Airports Offer Unrealized Potential for Alternative Energy Production, is that the typical airport environment is already managed to include wide swaths of … [continued]
Advances in atomic-level isotope chemistry are leading to a leap forward in environmental and natural resource management as they spread from green research labs to industry and commerce.
It was recently announced that UK greenhouse gas emissions dropped 7% in 2011. “In 2011, UK emissions of the basket of six greenhouse gases covered by the Kyoto Protocol were provisionally estimated to be 549.3 million tonnes carbon dioxide equivalent,” the UK’s Department of Energy and Climate Change noted. “This … [continued]
Greece is confident that its considerable green energy goals and roadmap will lead it out of its economic troubles. Those plans, which include a €20-billion solar power initiative, are also supposed to lead it to 100% green electricity by 2050. Greece Wants to Become Major Solar Energy Player Lucas … [continued]
After a short bit of trouble this Winter as numerous members of the GOP and conservative media attacked GM’s Chevy Volt, the Volt has bounced back with force. “The Volt had its strongest sales month to date in March, with sales of more than 2,000 vehicles. Sales nearly doubled … [continued]
In a New York Times SundayReview piece last month – Drawing the Line at Power Lines – Elisabeth Rosenthal suggested that our desire for clean energy will require significant tradeoffs: There are pipelines, trains, trucks and high-voltage transmission lines. None of them are pretty, and all have environmental drawbacks. … [continued]
Since the first screw base and socket bulbs were made in 1882, lamps have been purchased based on wattage used. Fast-forward 130 years and there is a new metric for light bulbs — “lumens.” Lumens are a measurement of the amount of light produced. This makes a lot of … [continued]
Ecova, which we noted the other day won a 2012 ENERGY STAR Sustained Excellence Award and has a long history of ENERGY STAR recognition, recently created a cool infographic (below) with some pretty interesting — and even shocking — facts about commercial and industry energy use. One of the things that … [continued]
