A type of energy that is renewed in a short time and is made of fuels that are made from wood, dried plants and garbage is...

• Solar energy

• Biomass

• Water energy

• Nuclear energy

One advantage of wind turbines on land is-

• that crops can still be grown under them

• that they don't make any noise

• that they don't have any environmental impact

• that they can be placed anywhere that it's flat

• all of the above are true

One of the biggest benefits of using nuclear power is-

• that there isn't any waste

• that it's very efficient

• that it's cheaper than using fossil fuels

• that it's renewable
