Sustainable Energy Concepts Assessment

The video explores the transformative potential of renewable energy, examining solar, wind, and hydropower. It highlights the sustainability challenges each source faces, such as environmental impact and waste management. The need for innovation in energy storage and transportation is emphasized to transition from fossil fuels to a sustainable future.

What is the primary characteristic of renewable energy?

• It is only derived from solar power.

• It is always cheaper than non-renewable energy.

• It can replenish itself over time.

• It is derived from fossil fuels.

Which of the following is NOT a criterion for sustainable energy?

• It must be affordable.

• It must be safe for the environment.

• It must be accessible.

• It must be non-renewable.

What is a major environmental concern associated with the manufacturing of solar panels?

• They require a lot of water and electricity.

• They are made from non-recyclable materials.

• They are too expensive to produce.
