Geothermal energy production cost $66 to $109 per MWh, while the cost of onshore wind energy and solar photovoltaic energy at the utility level ranged from under $40 to just $86 and $78 per MWh, respectively. Offshore wind enery costs were between $70 and $157 per MWh. The midpoint estimate for Virginia’s planned offshore wind park stood at a comparably low $92 per MWh. At the same time, a MWh from Georgia’s new nuclear plants Vogtle 3 and 4 – which became infamous for their cost overrun – was estimated at $169 and $228, respectively. The most pricey way to produce energy is by single-cycle gas plants, but these also fulfill the function of meeting demand during spikes in energy use as they can be turned on and off quickly.
