Solar Energy - A Hot Look
Solar energy is a renewable energy source.The heat and light that emanates from the sun has been used by people from earlier times itself for making fires and drying things.The non renewable energy sources are fast depleting and becoming costlier.Solar energy is a cost effective energy source that can be harnessed to solve the energy crisis.
There are two types of solar energy technologies: active and passive.The solar heat is captured through panels in the active category whereas the passive type consists of more complex technologies which make use of other materials as well.Pumps, fans and photovoltaic panels are used to harness the solar energy.
Solar energy is beneficial because it is clean, cost effective, helps reduce cost of fossil fuels, renewable and does not pollute the atmosphere.
Tip: With the introduction of subsidy in India for Gas cylinders, it is very wise to invest in solar cookers especially because India has a warm climate and solar energy can be tapped to cook and also save precious money, time and energy.It will also reduce pollution caused by other traditional cooking methods like firewood or coal stoves
