The World Uses a Variety of Different Energy Sources

The world is dependent on a range of different sources of energy. Fossil-based fuels such as natural gas, oil, and coal–accounted for more than 81 % of the energy consumed in 2018. Renewable sources such as wind power, solar energy, biomass, and hydroelectricity account for 14 percent. Nuclear energy accounts for another 5percent. Different countries use different types of energy sources, balancing the needs of the economy with environmental concerns.

Nature’s energy can be found in a variety of forms including sun, wind waves and ocean. When harnessed and transformed into more practical forms of energy, such as 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 other energy sources that are not renewable can be harmful to the environment. Oil mining, for instance is a destructive process that can destroy the forests that are virgin https://leonardogiombini.it/2021/07/05/generated-post to the earth. Fracking (hydraulic fracturing) can result in water pollution and earthquakes. Carbon dioxide is released when coal is burned which causes global warming.

Fortunately there are many promising sources of energy are renewable and sustainable. Hydropower, solar power and wind for instance, could generate electricity without the need to search for new sources.

Tidal and Wave Power are two other sustainable energy sources that are gaining popularity. However, to be used at a large scale they must have effective distribution networks. These must be built, which requires the use of non-renewable energy sources. Therefore, these sources are not yet able to provide the bulk of our energy requirements. Still, it’s important to be aware that prices for renewable energy equipment have decreased drastically over the last few years, and their efficiency is rising rapidly.
