Research some ways in which scientists and engineers have harnessed and currently use the energy in fossil fuels to benefit society. Think about how these methods involve a chemical reaction and explain how energy is conserved. Describe one method of using fossil fuels for energy and state one advantage and disadvantage about this method. In your replies to others' comments, state whether you agree or disagree with the advantages and disadvantages they list and explain your reasoning. Hint: Consider what happens to fossil fuels (such as coal, natural gas, and petroleum) when they are burned.
