28 Sep The World Uses a Variety of Different Energy Sources

The world uses a variety of energy sources. Fossil fuels–including oil, natural gas and coal–accounted to more than 81 % of all energy consumed in the year 2018. Renewables, like wind, solar power, hydroelectricity and biomass, make up for 14 percent. Nuclear energy is responsible for another 5%. Different countries employ different energy sources to balance economic needs and environmental concerns.

Nature provides energy in many forms such as wind, sun, waves and ocean. When harnessed and transformed into more efficient forms of energy, such as electricity or heat, these are known as primary sources. These sources are non-renewable resources of energy once they have been exhausted.

The environment is harmed by a variety of fossil fuels in addition to other energy sources that aren’t renewable. Mining oil, for instance is a destructive process that can destroy the forests of the earth. Hydraulic fracture (fracking) can trigger earthquakes and water pollution. The burning of coal releases carbon dioxide, contributing to global warming.

Fortunately, a majority of the most promising sources of energy are sustainable and renewable. Solar, wind and hydropower could, for example, generate electricity without having to dig for new sources.

Tidal and Wave Power are two more renewable energy sources that are gaining popularity. However, to be utilized in a large-scale manner they must have efficient distribution networks. This requires the use non-renewable energy sources to build these networks. These sources aren’t sufficient to satisfy the https://leonardogiombini.it/2018/11/17/dal-protocollo-di-kyoto-e-oltre majority of our energy demands. However, it’s important to keep in mind that costs for renewable energy-related equipment have fallen significantly over the last few years, and efficiency is increasing rapidly.
