Question

What is one reason for the United States to develop alternative-energy sources?

Answer 1

Oil is a finite resource

Step-by-step explanation:

Even if the United States had control over all the oil in the world, there's only so much oil in it because Petroleum is a finite resource. Even if it takes centuries for it to end, it will end. An alternative is necessary for when the time comes that we can't rely on Oil anymore.

Answer 2

One reason would be because there could be only few oil reserves. There could be a reason for energy sources to stop if the oil reserves and the supply could be lessen, providing no energy resource. That is why the United States tries to discover new alternative energy sources that could also contribute into making energy and prevent it from losing sources.
