This CleanTechnica article discusses how Hawaii has moved into solar and other clean energy technologies – at 1 cent per kilowatt-hour.
According to the Hawaii State Energy Office:
“From July 1, 2017 to March 31, 2018, the program invested over $22 million to deliver more than 1.8 billion kWh in estimated lifetime customer-level energy savings at a rough cost of one cent per kWh. This is equivalent to building a 92 MW solar farm, enough to power 288,000 homes for a year. In addition, this will reduce greenhouse gas [pollution] by nearly 1.5 million tons.”
