In my usual scourging on the net regarding environmental issues, I came across an article of The Economist which is couple of months old nonetheless and as I read through it, it made it realize that the term we use “Alternate energy” may not be alternate any more.
When scientists were giving presentations, seminars about the need of shifting the use of fossil fuel into alternate fuels around the late 80s, it definitely took time for it pick up. Currently the use of solar and wind energy have increased significantly over the last 10 years, powering a small portion of national girds of many countries. Initially costs of these were quite high, and not preferred such an example would be of solar energy. The entire process of harnessing the Sun’s energy and converting that into electricity was very expensive but now with prices coming down ( notable because of research, production costs coming down) , it has become a common household item.
Ok so as the article goes, solar and wind energy cannot be termed as alternate energy source anymore. Why? Its because as I mentioned, they are now powering major countries. Germany is now mostly dependent on solar and wind if not fully but with its nuclear programs being shut down by 2020, these two sources of energy will eventually become its main contributor of power.
Anyways read the article here.
