Wind Power Grade 3

What is a renewable energy source?

• Solar, wind, hydro, geothermal, and biomass

• Coal, oil, natural gas

• Nuclear power

• Tidal energy

Name one benefit of using wind power.

• Noisy

• Cost-effective

• Environmentally friendly

• Limited availability

How does wind power work to generate electricity?

• Wind power generates electricity by harnessing geothermal energy.

• Wind power generates electricity by converting the kinetic energy of the wind into mechanical power using wind turbines.

• Wind power generates electricity by burning fossil fuels.

• Wind power generates electricity by using solar panels.

Explain how wind turbines convert wind energy into electricity.

• Wind turbines convert wind energy into electricity by burning fossil fuels.

• Wind turbines convert wind energy into electricity by using solar panels.

• Wind turbines convert wind energy into electricity by harnessing geothermal power.

• Wind turbines convert wind energy into electricity by using blades to capture the kinetic energy of the wind and turning a generator.

Why is wind power considered environmentally friendly?

• Wind power produces electricity without emitting greenhouse gases or other pollutants.

• Wind power is expensive and inefficient

• Wind turbines are noisy and disrupt wildlife

• Wind power uses up a finite resource

What is the role of wind power in reducing greenhouse gas emissions?

• Wind power contributes to greenhouse gas emissions by releasing harmful pollutants into the atmosphere.

• Wind power helps reduce greenhouse gas emissions by providing a clean energy alternative to fossil fuel-based power generation.

• Wind power has no impact on reducing greenhouse gas emissions compared to other energy sources.

• Wind power increases greenhouse gas emissions due to the manufacturing process of wind turbines.

Describe how wind power can help in reducing air pollution.

• Wind power increases air pollution by releasing harmful particles

• Wind turbines contribute to greenhouse gas emissions

• Wind power is a clean and renewable energy source that does not produce harmful emissions, reducing the reliance on polluting sources of energy and helping in reducing air pollution.

• Wind power releases toxic fumes into the air

How does wind power contribute to a cleaner environment?

• Wind power contributes to air pollution by releasing harmful emissions.

• Wind power generates electricity without emitting greenhouse gases or other pollutants.

• Wind power increases the carbon footprint due to the manufacturing process of turbines.

• Wind power consumes large amounts of water resources, leading to environmental degradation.

Explain the concept of wind farms and their impact on the environment.

• Wind farms are harmful to wildlife due to the spinning blades of the turbines.

• Wind farms are clusters of wind turbines that harness wind energy to generate electricity. They have a positive impact on the environment by producing clean, renewable energy without emitting greenhouse gases or other pollutants.

• Wind farms deplete natural resources and contribute to deforestation.

• Wind farms contribute to air pollution by releasing toxic fumes during operation.

What are some ways in which wind power can help in conserving natural resources?

• Wind power contributes to environmental degradation

• Wind power increases the consumption of non-renewable resources

• Using wind power reduces the consumption of non-renewable resources and minimizes environmental impact.

• Using wind power has no impact on natural resources
