I WONDER - What Is Renewable Energy?

Renewable energy is derived from sources that are inexhaustible, unlike fossil fuels which are finite and harmful to the environment. Renewable energy is environmentally friendly and includes types such as solar, wind, hydroelectric, and geothermal energy. Solar energy harnesses the sun's heat and light, wind energy uses wind to turn turbines, hydroelectric energy utilizes water and tides, and geothermal energy employs steam from underground hot water to generate electricity.

What is a key difference between renewable energy and fossil fuels?

• Renewable energy sources are unlimited, while fossil fuels are finite.

• Fossil fuels are better for the environment.

• Renewable energy is more expensive than fossil fuels.

• Fossil fuels are a type of renewable energy.

How is solar energy primarily generated?

• By using wind to turn turbines.

• By using tides to power turbines.

• By extracting steam from underground.

• By storing heat and light from the sun.

What is the main method by which wind energy generates electricity?

• By using water currents.

• By harnessing geothermal steam.

• By turning turbines with wind.

• By using solar panels.
