Where to Find Limitless Replenish-able Solar Energy Resource?
When we speak of solar energy these days, it is electric power that suggests itself. Electricity is held in batteries called photovoltaics that are recharged by the sun’s rays thru solar panels. There are many methods of utilising the sun’s energy for electrical generation and distribution. But are you aware that solar energy is used for many other purposes besides electric power?
Given that the times of old, traditional man had learned how to use solar energy for his survival and comfort. The sun’s heat, as an example, is used to dry anything that man wants dry. Fish, meat and other foodstuff is dried under the sun for preservation and superior taste. Man also discovered that dry raiment felt good and he had the sun to do the job. And he was thankful for the heat he felt under the blissful sun.
As civilisations advanced, so did man’s use of everything inside his “grasp”, which includes the sun’s energy. He learned the best way to position buildings to get perfect cosy warmth inside. Solar heated water was used for bathing in cold climates and seasons. Man also realized to design his dwelling so that maximum daylight is dispersed inside. It was combined with ventilation design and engineering for dwelling comfort. He also discovered the correct components for these purposes and optimized usage of the knowledge, resource and technology then prevailing.
Most or all of these are still in use today but man has a tendency to make short-cuts and not bother with details like light and ventilation engineering. He relies on the supply of straightforward solutions like synthesised electrical lights and aircon. This comprises use of more electrical power that when reckoned on the macro scale, adds up to staggering costs we all pay for petroleum-based or carbon-based fuels used by at least 80% of power generation in the US. It might be lesser in other nations but still substantially alarming considering that fumes from use of this kind of fuel and its processing / refinement does lots of damage to our environment.
Use or renewable energy is man’s best alternative for ecologically-friendly and safe electric power generation. It is deserving of note that we only utilise a diminutive percentage of all of the solar electricity that successfully reaches the earth from that fiery ball far away up there. The sun’s power is a huge resource but is not popularly in use as solar electrical power source because it is yet dearer per unit of energy as compared to the current facilities for electric power generation. The price tag is nonetheless , declining in the light of new technologies and enlarging awareness and support to the undertaking by many sectors.
Let us support green energy. For our own sake, our children’s and our children’s children’s.
