The information in the table below gives information about energy use in a typical house. A typical house in the United States uses about 10,900 kWh (kilowatt-hour) of electricity per year. 1 TWh (terawatt-hour) = 1 x 106 GWh (gigawatt-hour) = 1 x 10° kWh (kilowatt-hour). (c) One recent cost analysis report indicates that electricity from hydroelectric power can be produced for about $0.05 per kWh, while electricity from conventional coal-fired power plants can be produced for an average of about $0.11 per kWh. Calculate the percent change in the cost of electricity for a typical house resulting from a switch between conventional coal-fired power plants to hydroelectric power.

Electrical Heating Unit

The conversion of electrical energy to heat energy is known as electric heating. The heating system that converts the electrical energy to heat energy for various application is called electrical heating unit. Electricity is employed as the firing mechanism in electric heating systems, which transforms electric current to heat. Electric heaters have heating elements in the form of electric resistors.
