Unit 103 7202 Environmental - Renewable Energy

What is renewable energy?

• Energy collected from fossil fuels

• Energy collected from non-renewable resources

• Energy collected from naturally replenished resources.

• Energy collected from nuclear power

Name three examples of renewable energy sources.

• solar energy, wind energy, hydroelectric power

• coal energy, natural gas, nuclear energy

What are the advantages of using renewable energy?

• Renewable energy is unreliable and inconsistent.

• Renewable energy is expensive and not cost-effective.

• Renewable energy requires a lot of land and space.

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

What are the disadvantages of using renewable energy?

• Limited energy production, unreliable technology, and negative environmental impact.

• High initial costs, intermittent availability, and the need for large land areas.

What is solar energy?

• Energy derived from fossil fuels

• Energy derived from the sun's radiation

• Energy derived from wind

• Energy derived from the moon's radiation

How is wind energy generated?

• Wind energy is generated by burning fossil fuels.

• Wind energy is generated by using solar panels.

• Wind energy is generated by capturing the heat from the sun.

• Wind energy is generated by harnessing the power of wind to rotate the blades of a wind turbine.

What is hydroelectric power?

• Hydroelectric power is a form of renewable energy that harnesses the power of flowing or falling water to generate electricity.

• Hydroelectric power is a type of wind energy that uses turbines to generate electricity.

• Hydroelectric power is a form of renewable energy that uses solar panels to generate electricity.

• Hydroelectric power is a type of fossil fuel that is burned to generate electricity.

What is geothermal energy?

• Geothermal energy is the energy produced by wind turbines.

• Geothermal energy is the heat from the Earth.

• Geothermal energy is the energy generated from the sun.

• Geothermal energy is the energy obtained from burning fossil fuels.

What is biomass energy?

• Biomass energy is a renewable energy source derived from organic materials.

• Biomass energy is a type of nuclear energy.

• Biomass energy is generated from inorganic materials.

• Biomass energy is a non-renewable energy source.

What is the role of renewable energy in reducing greenhouse gas emissions?

• Renewable energy is not a viable solution for reducing greenhouse gas emissions.

• Renewable energy has no impact on greenhouse gas emissions.

• Renewable energy increases greenhouse gas emissions.

• Renewable energy replaces fossil fuels and reduces greenhouse gas emissions.
