Is hydropower the cheapest source of energy?

Hydropower offers the lowest levelized cost of electricity across all major fossil fuel and renewable energy sources, and costs even less than energy efficiency options, according to a recent study from Navigant Consulting and the American Council on Renewable Energy (ACORE).

Is hydroelectricity cheap or expensive?

Hydroelectric power is the cheapest source of renewable energy, at an average of $0.05 per kilowatt hour (kWh), but the average cost of developing new power plants based on onshore wind, solar photovoltaic (PV), biomass or geothermal energy is now usually below $0.10/kWh.

Why is hydropower so cheap?

Hydropower is the cheapest way to generate electricity today. … Producing electricity from hydropower is cheap because, once a dam has been built and the equipment installed, the energy source-flowing water-is free. Another reason hydro plants produce power cheaply is due to their sturdy structures and simple equipment.
