Solar power in Wyoming has the potential to generate 72 million MWh/yr. Wyoming used 12 million MWh in 1999. Wyoming is one of the country's windiest states and has the potential to generate 883 million MWh/yr from wind power. Solar and wind power tend to complement each other, with more solar power available in summer and during the day, and more wind power available at night and during the winter.Net metering is available to all consumers generating up to 25 kW.IREC best practices, based on experience, recommends no limits to net metering, individual or aggregate, and perpetual roll over of kWh credits. Installing a 5 kW solar array could cost $20,000 but is expected to pay for itself in 15 years, and go on to return a $15,166 profit over its expected 25 year life.
