Small-Scale GTL Growth?

 

Converting natural gas to liquid fuels using Fischer-Tropsch conversion is not a new idea but it has always required very large and expensive production facilities. Now Velocys is bringing to market new technology for small-scale GTL production at a fraction of the capital costs of traditional plants.[read more]

Why Having A Realistic View of Energy Efficiency Matters to Climate Change

Energy Efficiency and Climate Change

In response to our New York Times op-ed about the limits of energy efficiency and the furious reaction to it from some quarters, Andy Revkin asks whether we can find room for agreement on the rebound effect. And to some degree we already have.[read more]
