Fossil fuels are the main source of energy around the world. However, people are being encouraged to use alternative energy sources such as wind energy, solar energy and so on. Do you think this is a positive or negative development? Why? In many ways energy is the currency of our universe. From solar energy which gives life to our planet to electricity which gives life to inanimate objects mostly created by humans, energy is what runs/powers our world. After decades of dependence on fossil fuels, the world, taking positive steps, is now trying to replace them with other forms of energy which are infinite and clean. The first reason to shift from fossil fuels to alternative energy is/concers perhaps pollution. After only years of using oil along with its byproducts, we are now on the verge of destroying our old planet. Captivated by the massive energy generated, the revenue gained, and the progress achieved, humans have started to successfully set fire on to fossil fuels as well as the earth. The demand for this source of energy markedly rose has risen in many parts of the world ever since, and subsequently fueled by industrial transformations in many other countries. This highly ever competition has put the environment under threat by releasing greenhouse gases and contaminating rivers, seas and oceans. Clean energy, on the other hand, can be an answer to all these seemingly insoluble problems as these sources of energy such as solar and wind are directly harnessed from nature and do not harm the environment In addition to environmental problems posed by fossil fuels, these natural resources are limited. Our oil dependency in order to power our factories and homes seems to result in a catastrophe as it is only finite, and will dry up eventually. All countries in the world, rich in oil and gas or not, are doomed to substitute other forms of energy for carbon-based ones, and stop being heavily reliant on these natural resources. It is only the a matter of time that before this once- believed- eternity comes to an end. Moreover, considering the growth of economy as well as transportation throughout the world, a further escalation of the energy crisis now seems inevitable. This is in fact the reason that many developed countries have made a great deal of effort to take advantage of other natural resources and switch to renewables to mitigate the incoming adverse effects and survive the energy apocalypse. Britain, as one of the world leaders in this growing sector, can be a fine example as it has recently succeeded in replacing fossil fuels with renewable energy, and thiswhich has brought them a large number of financial and environmental benefits. To conclude, although our today’s world seems unlikely to be able to take any instantaneous action to replace fossil fuels with clean energy, the urge coming/deriving from the environmental aspects and the eventual end of natural resources makes us to switch to renewables.
