Why is there a need for solar energy?

There are lowering rates of non-renewable energies such as coal, natural gas and oil. These are said to run out within the next hundred years they are millions of years in the making and hundreds in the breaking. This is the reality that human society must face and find another option for a power source of energy to live on. The need for solar energy stems from the world’s need for electricity and when there are no fossil fuels left there will be a need for renewable energy such as solar power. The renewable energy sources are environmentally friendly and this is a very needed aspect in our energy sources. Carbon dioxide emissions have contributed to global warming, which in the long run will melt the polar ice caps and flood the continents. Carbon dioxide has also contributed to putting a hole in the ozone layer and therefore there is a higher risk of skin cancer within Australia. There is hope though, if people reduce their energy intake and wake up to the fact that their home (the earth) is dying.
