The World Uses a Variety of Different Energy Sources

The world relies on a variety of energy sources. In 2018 fossil fuels, such as oil, gas and coal, made up more than 81 percent energy consumed. Renewables, such as solar power, wind, biomass and hydroelectricity, account for 14 percent. Nuclear energy accounts for another five percent. Different countries have different energy sources to balance environmental and economic requirements.

Nature’s energy comes in many forms: sun, wind, waves and ocean. When harnessed and transformed into more efficient forms of energy, such as heat or electricity, these are referred to as primary sources. When the energy source is exhausted, they are non-renewable energy sources.

A lot of fossil fuels and a few of the other sources of energy that aren’t renewable are damaging the environment. For example mining for oil can degrade the world’s forests. Fracking (hydraulic fracture) can lead to earthquakes and water pollution. The combustion of coal releases carbon dioxide, contributing to global warming.

Fortunately, a lot of the most promising sources of energy are sustainable and https://leonardogiombini.it/2018/11/17/dal-protocollo-di-kyoto-e-oltre/ renewable. Hydropower, solar power and wind, for instance, can produce electricity without having to search for new resources.

Tidal and Wave Power are two other sustainable energy sources that are emerging. However, in order to be utilized on a large scale these technologies require efficient distribution networks. These need to be built using a source of non-renewable energy sources. These sources aren’t sufficient to provide the majority of our energy requirements. However, it’s important to keep in mind that the costs for renewable energy equipment have decreased dramatically over the past few years, and their efficiency is rising rapidly.
