By reducing our dependence of foreign oil and increasing alternative energy sources such as ethanol, we can begin to bring down prices at the pumps, create thousands of new jobs and bring a much needed boost to our economy.

If the United States is to protect itself from the economic and the political threats created by this excessive dependence, we must reduce our reliance on foreign energy sources and on foreign oil as quickly and as efficiently as possible.

If we don't continue to pursue alternative, emissions-free energy sources like nuclear fuel, we are at risk of increasing our dependence on costly natural gas.

Our dependence on foreign energy sources is our Achilles heel, not just in the realm of diplomacy, but in terms of our future as the world's economic leader.

I actually think the civil service, who are the malignancy at the heart of public life, have consciously prevented, talked ministers out of, made it difficult regulatory-wise, to allow more pressure on alternative energy sources to grow.

The U.S. now imports over half of its oil supply from the Middle East. This dangerous dependence on foreign energy sources is an issue of national security.

There's an overemphasis on conservation and other idyllic energy sources that can be harmful in that it hampers new technology and innovation.

Electricity is derived from many non-renewable energy sources like oil, natural gas and coal.

The more energy-efficient we become as a nation, the less we need to develop additional energy sources.

The sooner we get started with alternative energy sources and recognize that fossil fuels makes us less secure as a nation, and more dangerous as a planet, the better off we'll be.
