The World Uses a Variety of Different Energy Sources

The world relies on a variety of energy sources. In 2018, fossil fuels, like gas, oil and coal, comprised more than 81 percent energy consumed. Renewable energy sources like wind power, solar energy, biomass, and hydroelectricity are responsible for 14 percent. Nuclear energy is responsible for another 5%. Different countries employ various energy sources, in order to balance the environmental aspects with economics.

Energy is present in nature in a number of forms: sunlight, wind, waves, ocean and more. When harnessed and converted into more practical forms of energy, such as heat or electricity, these are called primary sources. These sources are non-renewable resources of energy once they have been exhausted.

The environment is harmed due to a wide range of fossil fuels along with other non-renewable sources of energy. Oil mining, for example, can destroy the forests that are virgin to the earth. Hydraulic fracture (fracking) can cause earthquakes and https://leonardogiombini.it/2021/07/13/generated-post-2/ pollute the water. The burning of coal releases carbon dioxide, contributing to global warming.

Fortunately that many of the most promising sources of energy are sustainable and renewable. Solar, wind and hydropower can create, for instance, electricity without having to dig up new sources.

Other sustainable energy sources are gaining momentum, such as wave power and tidal energy. To be utilized on an extensive scale, these technologies require effective distribution networks. This requires the use of non-renewable energies to build these networks. These sources are not able to fulfill the majority of our energy demands. However, it's important to keep in mind that prices for renewable energy equipment have decreased drastically over the last few years, and efficiency is increasing rapidly.
