The sources of the renewable energy – is it worth it?
In the age of new technology, where ecology and sustainable development are on the centre of attention, the designers are standing up to the new challenges. The sources of renewable energy are becoming much more popular than they were a couple of years earlier. Back to then, it was connected with big winds and solar farms or the companies which could afford green energy. The main reason were the high prices of the technology equipment which was necessary to construct the elements and machines which generate this energy. Nowadays, we can see the tendency of the prices of solar panels declining in the last 40 years.
