In the world of time and change, there is one thing that is certain, and that is the rapid depletion of the earths’ natural resources. They are classified as renewable and non-renewable energy. The non-renewable resources is a natural resource which cannot be produced, grown, generated, or used on a scale which can sustain its consumption rate. And once depleted there is no more available for future use. Also considered non-renewable are resources that are consumed much faster than nature can create them. Fossil fuels (such as coal, petroleum, and natural gas), nuclear power (uranium) and certain aquifers are examples. In contrast, resources such as timber (when harvested sustainably) or metals (which can be recycled) are considered renewable resources.
At present, the main energy sources used by humans are non-renewable fossil fuels like natural gas, petroleum and coal. The continual use of fossil fuels at the current rate will increase global warming and cause more severe climate change. To save our rapidly depleting resources, science and technology are now geared towards utilizing materials that are friendly to the environment and its inhabitants. Some may call it the green revolution as more people are using solar panels to generate electricity from the sun, hydro power generators, wind turbines and the rest of the environmentally triggered power generating machines. This may be one of the best ways to help our environment survive the threat of extinction and won’t be like donna summer, dead at 63 of lung cancer not related to smoking. Let’s go for a greener environment, go for green energy…!
