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.
