There are numerous advantages to be found with Green Solar energy for potential customers.Firstly, it affects your energy bill in a big way. If we can provide a free and plentiful source of power such as the sun's rays-then why not do so at once? At present every "unit" of solar electricity costs only 2 cents (RMB 0). Secondly, this sort of energy environmentally friendly. During normal operation it does not emit any greenhouse gas. This makes it rather difficult to see how or why critics could raise objections against such a wonderful thing. Before we enter into a period of irreversible environmental destruction, we should therefore protect solar energy. It is environmentally friendly and has simply enormous potential to supplement our future needs for electricity and heating. Also, solar energy systems need little maintenance and can last decades. In the long run this means a huge savings. And last but not least, installing solar panels on one's property can increase its value and is a hedge against rising energy costs in the future. Finally, governments or compasnies may offer incentives and rebates for the initial investment in such a system. Thus green solar energy is within reach of ordinary people economically as well practical.
