The conventional coal-fired power plant has an efficiency of about 33%. Assuming that all the coal in Example 8–3 were used to generate electricity (it was not), estimate the time until exhaustion, if the efficiency were raised to 40%.In 2004, the international consumption of coal for energy was 120.8 EJ (EIA, 2006). Assuming the 2004 demand remains constant, how long will world reserves last? The average world consumption of coal-based energy increased 5.15% per year from 2000 to 2004. If that rate of increase remains constant, how long will world reserves last?
