The World Uses a Variety of Different Energy Sources

The world uses many different energy sources. In 2018 fossil fuels, such as oil, gas and coal, were responsible for over 81 percent of the energy consumed. Renewable energy sources like wind power, solar energy biomass, hydroelectricity, and wind power are responsible for 14 percent. Nuclear energy accounts for another 5 percent. Different countries employ different sources of energy to meet economic needs and environmental concerns.

Nature’s energy is available in a variety of forms including sun, wind waves and ocean. When harnessed and transformed into more convenient forms of energy, like heat or electricity, these are known as primary sources. These sources of energy become non-renewable sources of energy once they have been exhausted.

Many fossil fuels as well as some of the other nonrenewable energy sources are causing harm to the environment. Oil mining, for example, can destroy the forest ecosystems of the planet. Hydraulic fracture (fracking) can cause earthquakes and pollution of water. Carbon dioxide is released when coal is burned and contributes to global warming.

Fortunately that many of the most promising sources of energy are sustainable and renewable. Wind, solar and hydropower could generate, for instance electricity without the need to dig for new sources.

Other renewable energy sources are gaining momentum, such as wave power and tidal energy. To be used at an extensive scale, these technologies require efficient distribution networks. They need to be constructed which will require the use of non-renewable energy sources. These sources aren’t sufficient to fulfill the https://leonardogiombini.it/2019/03/01/le-biomasse-i-processi-termochimici/ majority of our energy demands. It is important to keep in mind that the prices of renewable energy equipment have fallen dramatically in recent years and the efficiency is rising.
