Xcel Energy, Colorado's largest utility, may soon be required to cut emissions at coal-fired power plants and start using more natural gas, which is seen as a transition fuel to a cleaner energy economy.

The Colorado State Legislature gave final approval on Wednesday to the bill, which now awaits Governor Ritter's signature. (He helped draft the legislation—he also has other green accomplishments under his belt—so that isn't expected to be a problem.)

Forbes reports that under the bill, Xcel Energy would be able to "sign long-term contracts to lock in lower prices for natural gas and a guarantee that consumers will have to pay that negotiated price."

Especially with the recent offshore drilling announcement, every move toward cleaner energy seems even more valuable. Can't wait for the next one.
