As you know, our world is heavily dependent on oil. In Chapter 6 of Contemporary Environmental Issues, you have read that there is concern about the possibility of reaching a peak in oil production, while Chapter 8 of Contemporary Environmental Issues introduces a variety of possible alternative energy sources. Based on the concern that we may be running out of oil, describe at least two renewable alternatives to oil that are currently available and discuss the barriers that keep these alternatives from replacing oil as our primary means of energy. Do not discuss other fossil fuels or nuclear energy, which are all nonrenewable sources.  Additionally, discuss the role that government plays in ensuring a transition to these renewable alternatives in a post peak-oil world.

Your initial post should be at least 250 words in length. Utilize at least two scholarly or reputable resources and your textbook to support your claims. Cite your sources in APA format. Quoted text should constitute no more than ten percent of your post.  Respond to at least two of your classmates’ posts by Day 7.
