The brewing solar trade war between the United States and China sullies what should be a triumphant moment in the global photovoltaic (PV) industry: the arrival of affordable solar electricity.
The last decade has seen a sustained campaign by the hydraulic fracturing (‘fracking”) industry against its critics, as the fracking industry in the U.S. alone was worth an estimated $76 billion in 2010 and is projected to grow to $231 billion in 203

There’s cynicism, and then there’s Congress.
As energy companies move to drill in densely populated areas from Pennsylvania to Texas, battles are breaking out over who will have the final say in managing the shale gas boom. The fight, which pits towns and cities against energy companies and st
This chart is also fascinating, as it shows where our energy came from every year since 1800 - The answer? - Biomass (so, basically, burning wood chips, animal blubber, and any other organic product that can be turned into energy). Click thru for cha
Researchers have been laboring towards a quantum leap seeking to meet the soaring demand for smaller, more powerful, longer-lasting batteries. Some thought achieving such a thing would be nothing short of magic. The magic began in a small way during
Is the American bureaucracy holding deep insights and papers of Nikola Tesla? That's the argument this video (below) is making. The makers of the video advocate a day of protest demanding the release of Nikola Tesla's research to take place on Jan. 7
