The world uses a variety of different sources of energy. In 2018 fossil fuels such as oil, gas and coal, were responsible for more than 81 percent energy consumed. Renewable energy sources such as wind power, solar energy biomass, hydroelectricity, and wind power https://leonardogiombini.it/2021/12/18/technical-managerial-areas-in-the-civil-infrastructure/ account for 14 percent. Nuclear energy is 5 percent. Different countries employ different combinations of energy sources, and are able to balance environmental and economic requirements.
Nature’s energy can be found in a variety of forms including sun, wind waves and ocean. These sources of energy can be transformed into more practical energy forms, such as electricity or heat when they are harnessed. These energies become non-renewable sources of energy once they have been exhausted.
Many fossil fuels, as well as some of other energy sources that are not renewable have been causing environmental harm. For instance, oil mining, can destroy the planet’s virgin forests. Fracking (hydraulic fracture) can result in earthquakes and water pollution. The combustion of coal releases carbon dioxide, contributing to global warming.
Fortunately, some of the most promising sources of energy are renewable and sustainable. Hydropower, solar power and wind for instance, can produce electricity without the need to search for new sources.
Tidal and Wave Power are the other sustainable energy sources that are emerging. To be used at large scale, these sources of energy need to have effective distribution networks. This requires the use of non-renewable energy sources to construct these networks. These sources aren’t enough to satisfy the majority of our energy requirements. It is important to keep in mind that costs for renewable energy-related equipment have fallen significantly in the past few years, and their efficiency is growing quickly.
