Abstract: . . .  taking place? Has the rate of growth increased or decreased in the period 19801995 in comparison with 1965-1980? Assume an average capacity utilization factor of 75%, or 6570 hours per year of actual electricity production. 16-14. Landfill methane (see Chapter 9) can be a renewable energy source, as long as we keep supplying the garbage to the landfills. And we have been very good at that lately (see Figure 16-11).

The latter currently has greater economic appeal: electricity priced at 5 cents a kilowatt-hour is equivalent to oil at roughly $85 a barrel.” (a) Show that this equivalence is indeed correct. (b) Search the Internet (using keywords biomass and electricity) to get a sense of how popular this energy option may be. 16-13. In Vital Signs 1993, published by the The Worldwatch Institute, information is provided about the growth of hydroelectric capacity in the world since 1950. Make a . . .
