Solar energy produced by thermonuclear process that converts about 650,000,000[1] tons of hydrogen into helium every second. This process has resulted in the production of heat and electromagnetic radiation. The heat will remain in the sun and play an important role in sustaining thermonuclear reaction. Electromagnetic radiation (including visible light, infrared light and ultraviolet radiation)spread into space in all directions.
However, the sun provides energy to the earth in one second more than the energy used by the inhabitants of the earth in a day. Therefore, people should take advantage of the energy supplied by the sun is free.
Solar energy has been used since time immemorial. However, its use may not be as advanced as today's technology. Among the developed solar technology is Solar Thermal Energy, Solar Ponds, Ocean Thermal Energy Conversion and Solar Tower Technology. Among the factors that led to the development of solar technologies is increasing downward due to the energy resources available. Most of the existing power used by the Malaysian society is the source of Natural Gas (54.4%) and coal (40.2%). The rest is generated by hydroelectric stations and petroleum.
