Conserving energy is one of the main topics discussed in lecture so far. In the section called "Green Power"(p.170) under the sub category called "Solar Power", it is stated that new materials are being created, which allow making various products powered by the suns energy alone possible. By using these thin, yet strong organic-plastic solar panels, it is now easy to apply this product making almost anything now created to be powered by natural energy. One question still remains in my head, as I read this. If we are now able to make almost anything powered by the sun, why aren't we seeing more of the products that we use on a daily basis with the same features? Why are al things that are powered by the suns natural energy still so expensive, and not easy to get for an affordable price for the average consumer?In a time where conserving energy is such a major concern, why are we not developing cheaper methods, in order to make most, if not all new products being made, able to be powered by the suns natural energy?
