Points earned on this question: 2 Question 8 (Worth 4 points) Compare the costs and benefits of fossil fuel energy to that of wind power. (Please include two costs and two benefits.) Essay Submission A benefit from fossil fouls is that it can generate a big amount of energy that we can then use. Another benefit is that it is used in cars and it gets us from one place to another in a matter of minutes/hours instead of days or weeks. A cost of fossil fuels is that it is not a renewable energy that we can use again and again. Another cost is that at some point from now, the fossil fuels will run out and it takes over a million years for them to be formed.
