Sunlight which is now famously known as solar energy is important to live, for plants, humans and animals and basically responsible for life on our planet. On this planet natural source of heat is light that come through sun. This light beam and heat is used by humans from decades for different purposes. Sometime we use it to produce electricity while some other times, we convert it into any other useable form of energy to fulfill our needs. Use of solar power is continuing from civilization of humans, the only difference that we feel today is modernization and innovations that technology has bought with time.
Now we save radiations that sun generate on different solar panels to use them later in absence of sun to continue our routine works. Solar energy not only bring light and heat with it, but it also make the wind blow, which is a renewable energy and is used for purpose of producing electricity with help of wind turbines.Different sources today emphasis on importance of solar energy, because it helps plants to grow that supply oxygen to humans to live. Beside this today, huge plants are working because of power supplied to them through solar energy.
Why Solar Energy?
Solar energy brings no harmful rays with it and is very natural and clean source for earth. This is important for earth as today it help different appliance to work because of solar electricity including solar heating appliances, solar cooling appliances and also solar lighting appliances. Besides this we prefer to use it because it is providing us with massive financial benefits, and in time of recession who would like to bear expenses instead of saving some money. This helps best as source of electricity and produce electricity at much cheaper rate than local providers of electricity. Today America is consuming more than 25% of worlds oil production regularly, if this rate of usage stay at this point then soon these resources would end. Due to high usage now, these natural resources are becoming rare and expensive for a common man.
So at this point of time, solar energy is helping us because by using these renewable sources of energy we can save some non-renewable natural resources. It is saving our cost at different points, we just need to install a system to produce energy by this mean and this one time investment can provide us with ease for some coming years. It is never waste of money, because this system pay you back more than your one time investments.
Historical and modern importance of solar energy:
We have already discussed about some major reason that shows importance of solar energy to us. Besides those there are some other reasons as well that make this kind of energy feasible for us.
If we look back then we will find that there was a time, when humans were not aware of techniques to make cloths or burn fire to get heat in winters. In those times, only source that provides them warmth feeling was heat of sun. Besides this, there was not light at that time and sunlight was only thing that let them hunt or look for food and necessities to live. In different cultures we can easily find signs of importance of sunlight and heat generated by it.
Today homeowners are enjoying many benefits due to use of solar energy, it have positive effect on environment and is not harming natural beauty and is eco friendly. House owners can now enjoy their own electricity, generated for themselves only. This independence is not enjoyed by home owners only, but businesses are also part of this league now.
