ABSTRACT
For many the answer to the “what” question is obvious. We must dramatically reduce reliance on fossil fuels, especially coal and petroleum, and expend the resources necessary to develop and deploy noncarbon energy technologies, namely renewables. As the old saying goes, “easier said than done.” Current reliance on coal and oil is the result of past and present economics and technology, and the answer to the “what” question requires us to rethink our approach to these fuels.
