Fossil fuels, such as coal, oil and natural gas, are the main source for many countries. However, some nations are using alternatie energy such as solar power and wind power. Do you think this is a positive or negative development?
Although fossil fuels stil remain the most important energy sources in many places, some countries are now already using alternatie sources like solar or wind power. In my opinion, it can be diffilt for a country to move towards using alternative energy at fist, but this development brings about several benefits in the long run.
On the one hand, the change towards using alternative types of energy would probably put a heavy financial burden on the government and companies as they will have to invest millions of dollars in purchasing and developing new equipment and facilitis for harnessing solar, wind or hydro-electric power. For example, the average cost of installing a wind turbine for generating electricity is about $3 million, and an average country would require a wind farm with hundreds of turbines to supply power to all companies and households. In addition, the production cost of large solar panels is still very high, which is why many countries, especially those with a poor economy, are stil unable to use this power source.
However, I still believe that shifting towards using alternative energy is a worthwhile investment due to the great benefits it brings. Firstly, fossil fuels are the main cause of air pollution nowadays since petroleum-powered vehicles and factories are releasing tremendous amounts of CO2 into the atmosphere every day. Therefore, replacing coal and petroleum with wind or solar power will help to reduce the level of emissions in the atmosphere and improve air quality. Secondly, fossil fuels, like natural gas or oil, are finite resources and will soon be depleted, which will potentially threaten the economy if there are no alternative sources. This fact emphasizes the need to develop renewable energy to gradually replace traditional sources when fossil fuels run out.
In conclusion, I hold the view that despite the high initial cost of new equipment and facilities, the switch from fossil fuels to renewable energy sources is stil necessary for the long-term development of the planet.
