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.
Rangarajan+and+Guggenberger+ and 41 kWh/acre, respectively [5]. The average Energy costs for Rolla, Missouri are $0.093 per kWh for the first 1,000 kWh of the month, and $0.083 for the remaining kWh of the month [6].Therefore, the projected annual energy cost of this farm would be $163 monthly or $1,957 annually.The average energy costs for Nebraska and Ohio are $0.075 [7] and $0.095 [8] per kWh, for a projected annual energy cost of $5,957 and $717, respectively.angarajan+and+Guggenberger+ and 41 kWh/acre, respectively [5].
