Solar energy, radiant light and heat from the sun, has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation, along with secondary solar-powered resources such as wind and wave power, hydroelectricity and biomass, account for most of the available renewable energy on earth. Only a minuscule fraction of the available solar energy is used.
The things a learned were very interesting. Solar Energy can revolutionize alot in the world. If we can continue to learn to use the power for our benefit then we can been better in medicine and curing different diseases.
