Question

How do alternate sources of energy help in conserving non-renewable resources?

Answer 1

Alternative energy sources, such as nuclear, solar, wind, and hydropower, help conserve non-renewable resources because they allow us to use less, little, or none of the non-renewable resource.

Explanation:

Let's just say that we only use coal to power everything. Because coal is a nonrenewable resource, we will eventually run out of it. But if, instead of coal, we used mostly renewable resources, nuclear, solar, and hydropower, there would be more coal to use.
