Lower consumption? Why do you think this is? 6) What percentage increase has solar energy consumption seen (in Trillion BTU) in the last 30 years? 7) Heating-Degree Days and Cooling Degree Days: What is the general trend and what are the potential implications? 8) Among OPEC countries, how much oil is being produced compared to the 1970s? 9) What share of US electricity comes from nuclear? Is there any trend since 1990? Explain.
