First off, since fracking has gotten an often deservedly bad rap for environmental damage, the case for natural gas must address fracking. Yes, fracking is bad in many places where it’s been done—places of high environmental and geological sensitivity. Fracking needs stricter and more vigilant regulation, and harsher penalties for malfeasance. In particular, the injection of waste fluids into underground wells. But we need natural gas for electricity generation as a bridge to a renewable energy future—not to mention its already widespread use for heating, where it is more efficient than electricity (and you have to think what generates your electricity), far cleaner than oil, and still farther cleaner than coal.

Carbon Debt from Biomass Burning
Burning “biomass”—trees, grasses, and other plant matter—to generate electricity has been considered a “clean” technology in some quarters. Currently, European countries do not count carbon dioxide emitted from biomass burning as part of their greenhouse gas (GHG) emissions. This is curious, given that burning biomass does emit carbon dioxide, as well as a small amount of methane. How renewable is biomass burning? Does it leave a “carbon debt” of carbon dioxide in the atmosphere?
