1 ton of coal costs $36 = $0.006 per KWH. 1 barrel of oil costs $70 = $0.05 per KWH. 1 cubic foot of gas $0.008 = $0.03 per KWH. In comparison to solar energy, the hydrocarbon fuel costs are significantly lower without rebates, tax benefits nor the cost of carbon emissions.A twoâKilowatt (KW) solar energy system costs about $45,000 and covers roughly half of a typical American householdâs energy needs.verage solar energy system costs = $8.95 per watt. In order to compare the solar energy costs to conventional hydrocarbon fuels, we must covert the $8.95 per into KWH. Letâs make two calculations to measure the total electric energy output over the lifespan of the solar energy system.
