54% of energy generated in the U.S. from Burning Dirty Coal, Petroleum, and Gas is lost.

We drill and spill and burn and pollute to get the energy and don't even use half of the energy that was generated.

In addition,  the US currently uses about 19.7 million barrels of oil a day, 71% of which goes to transportation via cars, trucks, buses, airplanes. So, the longer we rely on the internal-combustion engine to fuel vehicles rather than electric cars, bikes and public transportation, the longer we stay dependent on drilling for those rapidly diminishing fossil fuels, which means more risky wells in deep water areas of the ocean and the inevitable occurrence of another disaster like the BP Deepwater Horizon spill.
