Questions & Answers

Q: What is renewable energy and why is it important?

Renewable energy is generated from sources that naturally replenish themselves, such as solar, wind, hydro, geothermal, and biomass. It is important because it provides a sustainable alternative to fossil fuels, helping combat climate change and reduce greenhouse gas emissions.

Q: How does renewable energy combat climate change?

Renewable energy creates no direct greenhouse gas emissions and only minimal indirect emissions from manufacturing, installation, operation, and maintenance. By transitioning to renewable energy sources, we can significantly reduce the overall emissions that contribute to climate change.

Q: What are the advantages of renewable energy?

Renewable energy has multiple benefits. It decreases pollution, improves our health by reducing air pollution emissions, and offers a reliable source of power since these resources will never run out. Additionally, renewable energy prices tend to be stable over time due to low operational costs and the availability of free fuel sources.

Q: What are the downsides of renewable energy?

One downside is the difficulty of generating power on the same large scale as fossil fuels. Building wind farms and dams can disrupt wildlife and ecosystems. Another challenge is the intermittency of solar and wind energy, as they only generate power when the sun is shining or the wind is blowing. Battery storage can mitigate this, but it can be costly.

Summary & Key Takeaways

  • Renewable energy sources naturally replenish themselves and never run out, making them a sustainable alternative to fossil fuels.

  • Renewable energy creates minimal greenhouse gas emissions and decreases pollution, leading to a healthier environment.

  • Renewable energy is reliable, cost-effective, and offers a stable pricing structure over time.
