From the thesis abstract: "The United States must balance securing our energy future with protecting our environment from climate change. A holistic approach is required to solve this complex problem. We must reduce demand for petroleum, improve energy efficiency, and develop feasible alternative energy solutions to include emission capture technologies. The United States remains the largest consumer of energy products in the world and is the second leading producer of green house gas (GHG) emissions. Our dependence on imported petroleum is undermining our control of our national security interests. Petroleum comprises 63% of the United States' energy consumption, with the transportation sector accounting for 68% of the oil consumed. Energy flexibility or diversity, rather than energy independence, is the key to improving our national energy security."
