"It is clear our nation is reliant upon big foreign oil. More and more of our imports come from overseas"

This quote by George W. Bush highlights the truth that the United States is greatly dependent on foreign oil. This dependence on foreign oil has actually been increasing gradually, as more and more of our imports come from overseas. This reliance on foreign oil has a number of implications for the United States economy, consisting of increased expenses for customers, increased vulnerability to international market variations, and a decreased ability to manage our own energy security. Furthermore, this reliance on foreign oil has a number of environmental implications, consisting of increased emissions of greenhouse gases and other contaminants. It is clear that the United States requires to take steps to reduce its dependence on foreign oil and increase its usage of renewable energy sources. Doing so would help to reduce our dependence on foreign oil, improve our energy security, and reduce our ecological effect.
