We share this beautiful planet, with a lot of other creatures. But, humans are the only ones who are willfully disrupting the ecological balance. We are using non-renewable energy which is depleting the ozone layer, thus exposing the atmosphere to the ultraviolet rays of the sun. The one idea that can turn the sure destruction of the earth around, is the use of renewable energy.
The problem with Coal as a fuel is that it releases carbon emissions, which is harmful to the ozone layer. The depletion of the protective layer is regularly heating the planet up, resulting in melting of ice caps. The harmful ultraviolet rays cause cancers and other diseases. Fortunately for us, the planet gives us access to many different sources of clean energy like wind, water and sunlight, that are available easily and in unlimited quantities.
How would this benefit us? Well fossil fuels, coal and petroleum are formed after millions of years, they are exhaustible and are expensive. By using renewable energy we will spend less money on electricity. We can use solar powered outdoor light which also come with rechargeable batteries that are charged by the sun during the day. Solar water heater can be used for heating water. In this way we can also conserve energy. Government can set up solar farms and also give subsidies to the poor people. Renewable energy keeps the atmosphere clean as it does not give out harmful gases. India, which is choking on coal, still continues to resist committing to lower carbon emissions.
Instead of using petrol for cars which is more expensive, we can make solar powered cars which will also be cheaper. We can also construct solar powered buildings, use solar cookers. One of the great thing about solar power is that it produces its greatest output as demand spikes.
At this point though renewable energy accounts for only 1% of electricity generation, it will take years of concentrated effort by the government and by private investors to make the most of renewable energy. Since renewable energy is unlimited we should use it to the maximum instead of using our depleting fossil fuels which cause harm to the planet and its people.
