The Democratic Party's position on energy is much based on sustainable, clean, oil-free energy. They believe in a more independent America when America won't depend anymore on others for oil. They also defend that it is important to protect America's nature and preserve sensitive public lands - which can be done by changing the type of sources of the energy. Also, it is proposed that a greater support is given to those that wish to use more efficient energy, whether on houses, or cars, and also those that create energy-efficient vehicles and others.
So, the statements that apply are:
"The United States should develop all of its natural resources."
"The United States should encourage fuel efficiency."
