In spite of the obvious importance of solar energy for our future energy reserves, and the huge amount of energy, that the sun provide us for free, I want’ to emphasize some of the draw-backs of solar energy, with the current technology, and share some of my worries about the problem that using solar energy still have.
I intend to drip some cool water on the entire hot “solar power” lobby, not to abolish it, but to speed them up, and causing them to think again about the problems.
Although solar energy is a great source of energy, it is still can be unavailable and unreliable some time. we need to remember that on our spherical earth, receiving different amount of light during the day and throughout the year, making it hard to retain constant energy supply. moreover, our current devices require a huge surfaces of panels in order to collect a small amount of energy, making it unachievable.
solar energy, in our current situation is very expensive. Yes, sun is for free, but the current technology is very expensive, and in terms of surface needed relative to the production of electricity with fossil fuel, it is still very expensive. So prices have to be dramatically reduced , before it will become a good energy resource.
As I already said, our current technology is extremely inefficient. There are two main ways to produce electricity form solar energy: photovoltaic cells – which produce electricity directly from the sun, but are very inefficient and expensive, and heating fluids using the sun (like solar boiler), to drive turbines that produce energy. these two methods are still very ineffective, energetically speaking. There must be other ways to produce electricity efficiently from solar power.
Possible effect on the environment
Although it might sound strange, solar energy in its current form can be harmful to the environment. First, the materials used for the production of the panels, and the methods of production are very unfriendly to the environment. Second, these large surfaces, consume a huge space, and increasing the use of solar power will cost in many space wasted on solar panels. Third, increasing the reflecting surface of earth might cause a phenomenon of reflecting the sun light out, causing global cooling (this is not a joke!). Global cooling, looks good in first glance, might be horrific in the future. messing with earth climate was never a good idea. Not mention the effect that such a phenomenon might have on plants and photosynthesis, which are the basis for life.
effect on technology
Finally, since the current situation of solar energy in insufficiency and economically problematic, I think that the time to promote solar energy has not arrived yet, most of the concentration should be in increasing the investment in research and development, so the future generation will benefit from a good solar energy solutions.
