On a much larger scale, solar-thermal power plants employ various techniques to concentrate the sun's energy as a heat source. The heat is then used to boil water to drive a steam turbine that ...

A group of international researchers has examined how different designs affect the efficiency of photovoltaic-thermal (PVT) module efficiency. The scientists modeled eight different types of PVT ...

Ocean thermal energy conversion systems (OTEC) is a fairly simple and theoretically well understood potential source of primary energy that utilizes the difference between ocean temperatures at the ...
