What is renewable energy?

• Energy collected from naturally replenished resources.

• Energy collected from nuclear power plants.

• Energy collected from fossil fuels.

• Energy collected from non-replenished resources.

Give an example of a renewable energy source.

• Wind power

• Nuclear power

• Coal power

• Solar power

What are fossil fuels?

• Natural resources formed from the remains of ancient plants and animals.

• Renewable energy sources derived from wind and solar power.

• Man-made substances used for generating electricity.

• Chemical compounds found in rocks and minerals.

Name three types of fossil fuels.

• coal, oil, natural gas

• geothermal, biomass, nuclear

• solar, wind, hydroelectric

• wood, peat, uranium

What is non-renewable energy?

• Energy sources that cannot be replenished or regenerated in a short period of time.

• Energy sources that are not used frequently.

• Energy sources that can be replenished or regenerated in a short period of time.

• Energy sources that are only available in certain regions.

Provide an example of a non-renewable energy source.

• Coal

• Hydroelectric

• Wind

• Solar

What are biofuels?

• Fuels produced from renewable organic materials.

• Fuels produced from non-renewable organic materials.

• Fuels produced from inorganic materials.

• Fuels produced from synthetic materials.

How are biofuels different from fossil fuels?

• Biofuels have a higher carbon footprint than fossil fuels.

• Biofuels are made from synthetic materials, while fossil fuels are made from natural materials.

• Biofuels are more expensive to produce than fossil fuels.

• Biofuels are derived from renewable sources, while fossil fuels are formed from ancient plants and animals.

What are the advantages of using renewable energy?

• Renewable energy is expensive and not cost-effective.

• Renewable energy is unreliable and inconsistent.

• Renewable energy requires a lot of land and space.

• Renewable energy has several advantages such as reducing greenhouse gas emissions, improving air quality, creating jobs, and promoting energy independence.
