ABOUT SOLAR POWER >>
Solar power is sometimes used as a synonym for solar energy or more specifically to refer to electricity generated from solar radiation. Since ancient times solar energy has been harnessed for human use through a range of technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available flow of renewable energy on Earth.
Solar energy technologies can provide electrical generation by heat engine or photovoltaic means, space heating and cooling in active and passive solar buildings; potable water via distillation and disinfecion, daylighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes.
Solar power is energy which comes from the sun. This energy is very powerful and hits the earth regardless of whether or not we take advantage of it. Even the tiny percentage of sunlight that touches the earth is plenty to meet the energy and power needs of the entire human population more than 8,500 times over. The only concern is learning how to collect this energy efficiently. Today there are many different technologies which exist to achieve this goal. Due to concerns of the availability of traditional energy sources, many people today are interested in further developing renewable energy technologies, such as solar devices. For this reason it is sensible to expect continual improvement of existing solar technology and the invention of new solar power devices over the next few decades.
