Solar Energy


Solar and other renewable energy sources are the future of the human race.
That is not just me, that is the opinion of a lot of smarter people than I.
Without a shift in thinking that should have started some years ago, the oil will run out, and the human race will be left with no available energy.
That energy is needed not just to power the ipods, and make televisions work.. it's essential to run hospitals, run cars, and keep our society stable and in order.
With the oil all depleted, and with a population surpassing 10 billion people, riots will start, famine will follow and wars. Natural selection and the demise of the economy will plunge humans into self destruction to bring the population down. Can you imagine only 1-2 percent of the population remaining?
We're just about at what is called "The oil peak". It means that the oil wells reached the peak of their capabilities. And from here, the direction is down. When oil reserves end, our society will change completely.
Unless of course, the people in power take their heads out of the sand and start implementing emergency means to pre-empt. Such as reduction in energy consumption by law, and funneling many more funds into renewable energy research and development.
The photo at the beginning shows an option. This company produces a new breed of solar energy. Instead of using massive plates of photo-voltaic cells, that produce 10-15 % solar energy, they use mirror dishes that concentrate the sun rays into a focal center with only a few high grade cells. this allows for about 75 % efficiency. about 21 % electricity, and the rest is in thermal energy form - that is available to heat water for instance.
It takes much less space, most of its parts (about 95 percent) are recyclable, and its possible to ugrade its parts which makes its life very long.
Imagine, every house or building having one or two of these. It's enough to supply most of the energy requirements, and even sell back to the electric company. Plus, society stays alive.
Until the next crysis anyways.
