Report finds Solar uses far less water than nuclear, fossil fuel generation

The Civil Society Institute (Newton, Massachusetts, U.S.) has released a new report looking at water usage among different electricity generation technologies, which finds that solar photovoltaic (PV) and concentrating solar power (CSP) plants with dry cooling use far less water than many conventional forms of generation. "The Hidden Costs of Electricity: Comparing the Hidden Costs of Power Generation Fuels" finds that dry-cooled CSP plants use only around 300 liters of water per MWh, less than one-tenth of closed-loop nuclear reactors and one-sixth of the low end for coal generation. Water use for PV generation is also low.
