Clean Energy is the future.
Windmills and Photovoltaic cells. Some of the sources of future clean energy. Solar panels are getting more efficient, and gradually less expensive, all the time, thanks to ever-better designs which all them to focus the gathered sunlight on a more and more concentrated point. The size of the cells is decreasing as their efficiency rises, meaning that each cell becomes cheaper to produce and at once more productive. As far as the aforementioned cost, the price of producing solar-generated energy per watt hour has come down to $3.00 at the time of this writing. In 2000, it was nearly double that cost.
Solar powered electricity generation is certainly great for the environment, as this alternative form of producing energy emits no emissions into the atmosphere and is merely utilizing one of the most naturally occurring of all things as its driver. Solar cells are becoming more practical. Heating or Cooling, solar can do it. In the case of hot water generation, the system works by having the water encased in the cells, where it is heated and then sent through a distribution system.
Photovoltaic cells are becoming increasingly better at collecting sufficient radiation from the sun even on overcast or stormy days. One company in particular, Uni-Solar, has developed solar collection arrays for the home that work well on inclement days, by way of a technologically more advanced system that stores more energy at one time during sunlit days than previous or other arrays.
There is actually another solar power system available for use called the PV System. The PV System is connected to the nearest electrical grid; whenever there is an excess of solar energy being collected at a particular home, it is transferred to the grid for shared use and as a means of lowering the grid’s dependence on the hydroelectrically-driven electricity production. Being connected to the PV System can keep your costs down as compared to full-fledged solar energy, while at once reducing pollution and taking pressure off the grid system. Some areas are designing centralized solar collection arrays for small towns or suburban communities.
