In spite of all the natural energy which keeps our universe in activity, man still resorts to the most primitive of methods; digging up things and burning them.

We have to slow down the emissions of carbon dioxide and methane from coal burning, oil and eventually natural gas... And the best ways to do that are energy efficiency and a switch to renewables.

The younger ones, then passionate and puritanic, probably never knew that their urbanite fantasies would emerge as super erectiles of twisted metal and over-stretched concrete.

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

President Bush's energy program won't help lower gas prices or slow global warming.

The more traditional fuel sources we have relied on as a nation - coal, oil, and natural gas - I'm hoping they can allow us the financial springboard to move to the next generation of energy sources: renewables and alternatives.
