Clean and renewable energies are the sources of the future. Research has been under way for several years to find more efficient ways to produce more efficient, economical and cleaner energy. With the world having all its resources plucked without environmental care every day, the time will come when it will run out of resources. Oil, for example, is used as a source of energy, but it pollutes a lot, both when it is burned and when it is wrongly extracted and falls into the seas. Similarly, there is coal, which is a widely used energy source in the world, but emits pollutant gases into the atmosphere, as well as sulfides that can react with air or water. Hydroelectric plants are considered clean and renewable energy sources, but the construction of one, besides being very expensive, also needs a large space and a river, thus altering the ecological balance of the river and its course, besides clear a large area of forest for its construction. Because of all this, it is concluded that clean and renewable energy such as solar and wind energy can lessen the environmental impact caused by resource exploitation as well as reduce pollution and be more economically viable.
