Earth Science : Renewable Energy

The video tutorial discusses different types of energy resources, including perpetual, renewable, and non-renewable resources. It explains how perpetual resources like solar, wind, geothermal, and ocean energy are inexhaustible. Renewable resources can be replenished but may face demand challenges. Non-renewable resources, such as fossil fuels, are finite and require conservation efforts. The video also covers energy efficiency and conservation techniques, emphasizing the importance of using resources wisely. It concludes with encouragement for resource conservation and test preparation.

What is a perpetual resource?

• A resource that can be replenished quickly

• A resource that cannot be depleted by human use

• A resource that is non-renewable

• A resource that is only available during the day

Which of the following is an indirect form of solar energy?

• Wind energy

• Geothermal energy

• Nuclear energy

• Hydroelectric energy

What is a key challenge with renewable resources?

• Demand often exceeds replenishment rates

• They are always available

• They cannot be replenished

• They are non-renewable

Which of the following is a non-renewable resource?

• Wind energy

• Geothermal energy

• Natural gas

• Solar energy

What is energy efficiency?

• Using more energy to perform a function

• Using technology to perform the same function with less energy

• Turning off lights when not in use

• Recycling materials

Which of the following is a method to conserve energy at home?

• Using energy-efficient light bulbs

• Leaving lights on

• Taking long showers

• Using non-renewable resources

How can recycling help the environment?

• By increasing landfill waste

• By conserving resources and reducing landfill waste

• By using more energy

• By depleting non-renewable resources
