Energy and the presidential race

Where the leading candidates stand on everything from a gas tax to a carbon cap to drilling in the Arctic National Wildlife Refuge.

The Democratic front-runner favors the broad energy goals set by the Democratic-controlled Congress.

Like the other main Democratic candidates, Clinton wouldn't raise the gas tax and is opposed to drilling in the Arctic but supports carbon caps, conservation and taxing Big Oil.

"A cap-and-trade system [for carbon dioxide] is a better approach [than a gas tax] because it guarantees that we will meet our environmental goals - something that a gasoline tax cannot," Clinton said in an email to CNNMoney.com.

Like all the Democrats, the New York senator supports a mandatory carbon cap that would cut emissions 80 percent from 1990 levels by 2050. That is the amount scientists say is necessary to avoid widespread flooding and drought.

Clinton also supports an increase in fuel efficiency standards to 55 miles per gallon by 2030.
