Nowadays one hears of green building, green buildings, green energy and one doesn’t request; why is it green? Does this refer to only color or is there some other significance to it. Let us discuss energy and the reason it’s known as green.
Energy in itself doesn’t have color, so what exactly do we mean by ‘green energy’. There appears to be no single or universal definition for this, though it’s various interpretations. Can it be known as green because the color green is usually aligned with character and so what’s benign towards character becomes tagged ‘green’, in a fairly common way? But, there’s a good deal of agreement in tagging all sorts of energy that’s sustainable, renewable and environment friendly as ‘green energy’. Thus, energy made by wind, water, sunlight and atomic energy, normally, comes under this category.
Currently, energy derived from fossil fuels: oil, coal and natural gas satisfy the world’s requirements, by and large, however there’s an on-demand requirement for longer. The recognition that these power resources aren’t infinite but are being depleted and the world can come to a circumstance, where these will be wholly drained, has fueled the important need to locate alternative sources and it has been the focus of international research.
Nations are actively pursuing attempts at generating energy from wind, water and sunlight. Nuclear energy has also been created as a substitute source however. The current disaster in Japan was a set-back. Technological advances in extraction and production of ‘green energy’ by the several resources and the rigorous security criteria which are faked will help supply clean and secure energy for the long term.
Petrol, diesel and natural gas; all derived from fossil fuels are used in all kinds of transport vehicles until today, but for a long time? The investment and research to vehicles using hybrid is catching on since people and nations have become conscious of the harm to the environment caused, directly or indirectly, by the protracted use of fossil fuels.
