![]() This allows us to compare wind energy costs to the utility as well as solar. Then we’ll divide the total cost to install that turbine by how many kWh of electricity it produces in total. First, we’ll figure out how many kilowatt-hours of electricity the turbine in question will produce over its entire life. To find the $/kWh cost of wind energy, we’ll need to do some easy math. To save money with your renewable energy installation, you need your $/kWh cost to be lower than what your utility charges you. Of course that rate differs by state, with a low of just $0.09 per kWh in Washington and a high of $0.30 per kWh in Hawaii. In the US, the average utility charged $0.13 per kWh for electricity in early 2017. The easiest way to compare costs of different energy sources is to compare the $/kWh cost for each. ![]() How to Compare Costs Between Different Energy Sources We’ll answer all these questions as we look at how much wind energy costs for both residential and utility-scale turbines, and compare that cost to similarly-sized solar installations. But what if you want to install a small wind turbine on your own property? How much does wind energy cost? Is it a wise financial investment? How about when compared to solar? You might’ve heard that, at least for utilities, wind energy is a ridiculously cheap form of electricity – cheaper than any other method. How Much Does Wind Energy Cost? Comparing the cost of wind energy to the cost of solar energy.
