Solar Power vs Solar Energy

The terms 'Solar Power' and 'Solar Energy' are used interchangably, however the terms have different definitions. Solar Energy is utilizing the radiant energy from the Sun. Solar Power is the conversion of sunlight into electricity, either by photovoltaics and concentrating solar thermal devices, or the utilization of thermoelectric converters, solar chimneys or solar ponds. (some of the latter are experimental) When we consider building design, solar energy (and shading) are considerations. In order to conserve heat that the Sun delivers, thermal mass is used. Optimization of the light in buildings is called a 'Daylighting' technique. Solar water heaters are used in many applications including swimming pools and domestic hot water. Farmers use greenhouses to lengthen the growing seasons, as well as pumps that derive power from solar cells (photovoltaics) in order to move water for grazing animals. In order to harvest salt, as well as clean waste streams, evaporation ponds are used. In order to increase the supply of potable (drinking, cooking etc.) water, solar distillation and disinfection methods provide water for a great many people around the world. There are many simple uses for this renewable energy and the prospect for a great deal more. Keep reading, there will be more to follow.
