▶ Your Answer : Some people say that they worry about environment so that they invent renewable sources of energe and promote this energy. However, in my opinion, I disagree this statement for two reasons: Not only amount of problems and renewable energy's useless.
First of all, fossil fuels are still most effective method. Because they are buried all around the world enough to use we and our generations. We rely on fossil fuel that's why we wouldn't live without an electrical equipment. During our daily lives, we uses lots of electricity because we dirve car for commute and refrigerator in factory etc. Only possible way to meet growing world demand, fossil fuels can be perfect energy sources. Studies show that renewable energy only likely to account of 25 percent of demand by 2050. While coals account of 50 percent of demand. So if people uses fossil fuels, it would be much more resonable and they would uses a lot of machines easily as now. On top of that almost all machines and motorized equipment runs on fossil fuels. If people converts all equipment in short term, they would get into trouble cost problems and realistic problems. Converting all machines runned by electricity is very expensive and unrealistic. Additioned to, We don't have enough change into renewable energy sources techniques. In this circunstances, replacing fossil fuels to renewable energy makes nonsense and like foolishness.As for my family, two years ago, we wanted to install solar heating system in our house, However we didn't. Because changing solar heating system was too expensive more than we expected. We heard that installing solar heating system is much cheaper than used heating system based on fossil fuels from news , because they insisted that it runs by solar energy, not much needed money.
To sum up,I dissatisfied with this idea because not only renewable energy's useless and cost problems. For these reasons, I think people will still use fossil fuels.
