Fossil fuels are the main sources in many countries, but in some countries the use of alternative sources of energy is encouraged. Is it positive or negative development?

There is an unequivocal fact that fossil fuels have long been the essential energy sources in various regions around the world.

Nevertheless

can be considered as great progress with a lot more advantages than disadvantages. To be started with, the main perk of utilizing these alternatives can be addressed through the fact that while these are mostly renewable, infinite resources, all of the conventional sources like coal or oil are non-renewable. Fossil takes up millions of years to form and as in reality, the resource has been over exploited and will soon be depleted, the worldwide economy, as well as the future of our upcoming generation, would soon in jeopardy if there was no substitute power. In contradiction, energies like wind or solar are everlasting and needed to be developed to gradually replace the old resources. Another discernible merit of these substitute energy sources is considered to be environmentally friendly and as the results, suit well with the trend of sustainable development. There is a detrimental issue that has always been a heated public concern, namely the fact that fossil fuel has long been acting as the main catalyst to air pollution. In reality, a tremendous amount of exhaust fume is being released into the air every day by petroleum-powered vehicles and factories. With the alternatives, the level of emission in the atmosphere can be reduced and the air quality can be improved significantly, which will support long-run development as we reduce the harmfulness being put in our surroundings.

, all the changes in the power system may put a heavy financial burden onto the governments as well as companies, especially for those in developing countries. As to effectively generate solar, hydroelectric, or any other sorts of renewable powers, a massive budget will have to be invested in due to the purchase of equipment and facilities as well as the cost of formulating advanced technology. Not to be mentioned, most of the technologies involved in the methods of producing alternative powers are still in the process of completing or advancing, so much more colossal expenditures are unavoidable. All things considered, I hold the view that despite the prohibitive cost that needs to be spent, shifting toward alternative power utilization is a worthwhile and integral step in the sustainable development of humanity.
