Tons of wind farms. Super windy there. I know the idea is to fill two giant mine pits with water from the aquifer, and one would be higher than the other. During the day solar panels would provide energy to operate a water pump from the lower pit to the upper one. At night the water would be released to the lower pit which would provide power. It just seems like a short sighted answer. Why use pure water from an aquifer that will takes thousands of years to replenish?
