Right now the U.S. has a very real opportunity to transform our economy from one running on fossil fuels to one largely based on clean energy.

The energy team at Google has been crunching the numbers to see how we could greatly reduce fossil fuel use by 2030.

Our analysis, led by Jeffery Greenblatt, suggests a potential path to weaning the U.S. off of coal and oil for electricity generation by 2030 (with some remaining use of natural gas as well as nuclear), and cutting oil use for cars by 40%.

Our goal in presenting this first iteration of the Clean Energy 2030 proposal is to stimulate debate and we invite you to take a look and comment -- or offer an alternative approach if you disagree.

Over 22 years this plan could generate billions of dollars in savings and help create millions of green jobs.

(1) Reduce demand by doing more with less

(2) Develop renewable energy that is cheaper than coal (RE<C)

(3) Electrify transportation and re-invent our electric grid
