Renewable Energy Sources and Their Benefits and Limitations

The video explores seven types of renewable energy: solar, wind, hydroelectric, geothermal, ocean, hydrogen, and biomass. Each type is discussed in terms of its benefits, limitations, and potential impact on the environment and economy. Solar and wind energy are highlighted for their clean energy potential, while hydroelectric and ocean energy are noted for their environmental impacts. Geothermal and hydrogen energy are discussed for their potential and challenges, and biomass is examined for its carbon balance.

What is one of the main advantages of solar energy?

• It can be easily stored in large quantities.

• It has an endless supply due to sunlight.

• It is always available, even at night.

• It requires no initial investment.

What is a significant limitation of solar energy for homeowners?

• It cannot be used for heating water.

• It is more expensive than fossil fuels.

• It requires ample sunlight and space for panels.

• It is only available in urban areas.

How does wind energy benefit the environment?

• It does not pollute the air.

• It produces carbon dioxide.

• It releases harmful gases.

• It requires fossil fuels to operate.

What is a challenge associated with wind energy?

• It can be noisy and affect city skylines.

• It is only effective in urban areas.

• It is more expensive than solar energy.

• It cannot be used in rural areas.

What is a benefit of hydroelectric power?

• It generates pollution.

• It is limited to large-scale projects.

• It is versatile and environmentally friendly.

• It requires fossil fuels to operate.

What is a limitation of geothermal energy?

• It requires a large land footprint.

• It is not replenished naturally.

• It is vulnerable to earthquakes.

• It is inexpensive to build.

What makes ocean energy predictable?

• It is affected by weather conditions.

• It is only available during the day.

• It is consistent and easy to estimate.

• It relies on varying factors like sun and wind.

What is a disadvantage of ocean energy?

• It cannot be used near populated cities.

• It is more expensive than wind energy.

• It can disturb delicate ocean ecosystems.

• It is only available in landlocked states.

What is a benefit of using hydrogen as a fuel?

• It is a clean burning fuel.

• It occurs naturally as a gas.

• It requires no energy to produce.

• It is more polluting than fossil fuels.

What is a limitation of biomass energy?

• It requires no technology for use.

• It does not produce carbon dioxide.

• It is not renewable.

• Plants take time to grow.
