There are approximately 260 million passenger vehicles registered in the United States Assume that the battery in the average vehicle stores 540 watt-hours (Wh) of energy. Estimate (in gigawatt-hours) the total energy stored in U.S. passenger vehicles.
In 2001, the United States produced 51 percent of its electricity in the amount of 1.878x10^12 kWh from coal fired power plants. Taking the average thermal efficiency to be 34 percent, determine the amount of thermal energy rejected by the coal fired power plants in the United States that year.
Estimate the power required in the United States during the year 2050, in GW, and the energy consumed, in GJ, from the year 2010 to 2050 if the average consumption rate increases at an average rate of 3.2 percentage /year. Start with the 1980 annual consumption (78.067 quad at 1980 from Annual Energy Review 2011).

- You want to buy electric energy. You can buy from company A, B, C, or D,but you must choose only one. You obtain past data on these four suppliers, and you then determinethat the prices for some of them have been quite volatile, influenced by the state of the economy(recession, stagnation, and inflation). You assess this data given in the table below. Assuming that you simply want to minimize your average costs over the long run, determine theexpected costs for all energy suppliers.
