Renewables are here to stay, and the costs continue to drop while efficiency continues to climb. It's no longer sensible to pull all that carbon fossil fuel (petroleum, natural gas), out of the ground, especially when the hemp plant can do most of the things petroleum can do for less financial and environmental cost.

40% from rooftop solar
The National Renewable Energy Lab (NREL), a unit of the U.S. Department of Energy, now estimates that up to 40% of total energy needs could be satisfied by only placing solar panels on "suitable" rooftops. And that doesn't count the extra 10 panels you could have in your backyard, or the extra energy you could generate with a wind turbine or two.
