The World Uses a Variety of Different Energy Sources
The world is dependent on a range of different sources of energy. In 2018 fossil fuels such as oil, gas and coal, were responsible for over 81 percent of the energy consumed. Renewables, like wind, solar power, hydroelectricity, and biomass, account for 14 percent. Nuclear energy accounts for another 5%. Different countries employ different sources of energy to meet the needs of their economy and environmental concerns.
Energy is found in nature in many forms: sunlight and wind, waves, ocean and many more. These primary sources transform into more efficient forms of energy, like heat https://leonardogiombini.it/2019/05/11/cosa-sono-gli-impianti-a-biomasse or electricity, when they are harnessed. Once these energies are exhausted, they become non-renewable energy sources.
The environment is harmed by many fossil fuels, in addition to other energy sources that aren’t renewable. Mining oil, for instance can devastate the forests of the earth. Fracking (hydraulic fracture) can result in earthquakes and water pollution. Burning coal releases carbon dioxide, contributing to global warming.
Fortunately, a majority of the most promising sources of energy are sustainable and renewable. Hydropower, wind and solar, for instance, can produce electricity without having to search for new sources.
Tidal and Wave Power are the other sustainable energy sources that are gaining popularity. But, in order to be used on a large scale these technologies require efficient distribution networks. These need to be built using a source of non-renewable energy sources. Therefore, these sources aren’t sufficient to meet the majority of our energy needs. It is important to be aware that prices for renewable energy equipment have decreased drastically over the last few years, and their efficiency is rising rapidly.
