Question

part 1: definitions (short answer)

1. in your own words, define renewable energy.
2. in your own words, define nonrenewable energy.
3. explain one reason why renewable energy is considered more sustainable than nonrenewable energy.

Explanation:

1. Renewable energy is energy sourced from natural processes that are constantly replenished, like sunlight, wind, water - flow, and biomass. These sources are essentially inexhaustible within human - time scales.
2. Nonrenewable energy comes from finite sources that cannot be replenished quickly enough once they are used up. Fossil fuels such as coal, oil, and natural gas are prime examples, formed over millions of years.
3. Renewable energy is more sustainable because it has a virtually unlimited supply. Unlike nonrenewable energy sources which will eventually run out, renewable sources can be harnessed continuously without depleting the resource base.

Answer:

1. Energy from constantly - replenished natural sources like sun, wind, water.
2. Energy from finite sources that can't be quickly replenished, like fossil fuels.
3. It has a virtually unlimited supply.
