What are fossil fuels, and by what processes do we obtain energy from them? Compare and contrast the benefits and impacts of using the different fossil fuels and nuclear power. What are some of the challenges of safely using these fuels while minimizing their adverse impact on the environment and on society? What are the sources of bioenergy and in what ways is it used? What would be the impact of using it as our sole alternative, renewable energy source, especially as reliance on it increases due to depletion and costs of fossil fuels? How is solar energy harnessed and how is it converted to electricity? Provide at least two different examples.
