Why Solar Energy
Energy from sun is free and the sun will continue to shine for billions of years to come . Moreover the solar energy is inexhaustible, renewable and it’s irradiance is environment friendly. The solar power system does not emit CO2 , which is environmentally damaging .In addition ,silicon, the raw material in making solar cells, is the second most abundant element in the earth’s crust. Since the solar industry has been developing and the technology is maturing, the Pv power system are getting more efficient for both commercial and residential use. The price of PV system is also more affordable now due to recent price cuts.
In Contrast fossil fuels, as our main sources of energy are exhaustible and very fast. Our high dependence on fossil fuels is inevitably going to push up their prices continuously until they are used up. Fossil Fuels are nonrenewable and environmentally damaging. Recent climate change is in part a consequence from the increased CO2 concentrations in the atmosphere caused by burning fossil fuels.
Therefore, it is essential for us to seek alternative renewable energy resources for guaranteed energy supply and environment protection.Solar is the answer.
