Solar Energy - Political & Economical Issues


  
Storing solar energy at night and during cloudy days can be very expensive2. Nevertheless, solar power is the second-fastest-growing energy source today.
  
   If solar energy is absolutely free, why isnít everything powered by it? There are costs involved in creating, running and maintaining your solar (photovoltaic) system. There is a lot of hardware needed to set up this system. Typically around $32,000 is needed for a photovoltaic system23. Also, an installed photovoltaic system will cost somewhere around $9 per peak Watt23.  

   Parts of Europe and Japan are extremely focused and are investing heavily on the solar energy industry. The political commitment and support has promoted the development of solar electricity especially in Germany and Japan. The Greenpeace organization predicts that this political dedication forecasts that solar electricity sector is at a start of a massive transformation and expansion over the few decades. The objective is to increase the usage and demand for solar electricity while substantially lowering the greenhouse gas emissions.
  
   It should be noted, however, that this kind of a transformation will not happen by itself, and needs the support of both the consumers and the industry20.
