Concentrated solar power (CSP) is poised to be a critical component, when combined with solar photovoltaic (PV), wind, hydro and other forms of solar to provide all the energy we need for a sustainable future. CSP provides the critical storage capability for 7 by 24 operation, complementing hydro as a base load solution in a renewable energy powered world.
Concentrated Solar Power (CSP) makes use of the most abundant and free fuel there is, sunlight. The other trick with this old proven technology is that it can inexpensively store the collected energy from the sun in the form of heat so that it can operate 24 hours a day, seven days a week just like conventional non-renewable gas, oil and nuclear power plants. Solar thermal plants covering the equivalent of a 92 square miles in the equatorial region, in deserts, could generate electricity for the entire United States, for instance. Many other countries have substantial solar thermal resources sufficient, when combined with other renewable energy sources to provide all the power the world needs.
