How do we use natural gas to meet our energy needs?

Half the Carbon Dioxide of Coal

With oil supplies believed to be dwindling and an emphasis on developing domestic energy resources, natural gas has seen a resurgence in recent years, particularly because when burned, it produces about half the amount of carbon dioxide that coal does. Future carbon-credit markets or emission caps should also contribute to natural gas's rising popularity. And with prices ranging from around $4 to $5 per million British thermal units (MMBtus), it's economical, too.
