The decision to install solar electricity often comes down to tradeoffs in installation costs, payback times, and reductions in greenhouse gas emissions.  For the following questions assume a building has an electricity cost of $0.08 per kwh and the system uses 1,000,000 kwh per year. Assume the electricity supplied to the building by the utility provider comes from the following mix of sources: 35 % coal, 45 % natural gas, 10 % hydroelectric, 7.5 % nuclear, and 2.5 % wind energy.   How much does the building currently pay for electricity?
