Answer:
% change in the cost of electricity for a typical house = 54.55%
Explanation:
A typical house uses 10,900 kWh of electricity per year
Average cost of electricity production from hydroelectric power = $0.05 per kWh
Cost of production of electricity from hydroelectric power in 1 yr= $0.05 * 10900 = $545
Average cost of electricity production from conventional coal-fired power plant = $0.11 per kWh
Cost of production of electricity from hydroelectric power in 1 yr= $0.11 * 10900 = $1199
Change in the cost of electricity due to the switch in power source = $1199 - $545 = $654
% change in the cost of electricity = (654/1199) * 100
% change in the cost of electricity = 54.55%
