1) The United States should encourage fuel efficiency.
2)The United States should develop all of its natural resources.
Explanation: The Democratic party stands on a view that the United States oil and natural gas should be reserved for the future generations, by reducing the rate of production form it's reservoir. This means that other natural resources that can produce energy should be developed, so that the country will be able to have an independent energy source, that is free from the oil and gas reserve. And this will save the billions of dollars that is spent on oil subsidies from foreign countries.
The Democrats also stand on the view that efficient energy will help to reduce carbon and other environmental effect. This efficient energy can be produced from other energy source, that are not oil and Natural gas.
