Exploring Alternative Power Sources

What is a renewable energy source?

• Energy generated from nuclear reactions

• Energy derived from fossil fuels

• A renewable energy source is energy that is generated from natural processes that are continuously replenished.

• Energy that cannot be replenished

Which of the following is NOT a renewable energy source: solar, wind, coal?

• nuclear

How does solar energy work to produce electricity?

• Solar energy is generated by burning fossil fuels.

• Solar panels use wind to create electricity.

• Solar energy works by using photovoltaic cells to convert sunlight into electricity.

• Solar energy is produced through nuclear reactions.

Compare the energy efficiency of wind power and fossil fuels.

• Fossil fuels are more energy efficient than wind power.

• Wind power and fossil fuels have the same energy efficiency.

• Fossil fuels are the most energy efficient energy source.

• Wind power is more energy efficient than fossil fuels.

What is the main advantage of using renewable energy?

• It leads to higher greenhouse gas emissions.

• It has no impact on energy costs.

• It increases fossil fuel dependency.

• It reduces greenhouse gas emissions.

How does the cost of solar panels compare to traditional energy sources?

• The cost of solar panels has increased significantly over the years.

• Solar panels are more expensive than traditional energy sources.

• Solar panels are becoming more cost-effective than traditional energy sources due to decreasing prices and long-term savings.

• Traditional energy sources are always cheaper than solar panels.

What are the environmental benefits of using renewable energy?
