The World Uses a Variety of Different Energy Sources
The world is awash with a variety of energy sources. In 2018, fossil fuels, such as oil, gas and coal, accounted for more than 81 percent of energy consumed. Renewables, like solar power, wind power, hydroelectricity and biomass, make up for 14 percent. Nuclear energy is another 5 percent. Different countries use different types of energy sources, in order to balance the needs of the economy with environmental concerns.
Nature provides energy in many forms like sun, wind waves and ocean. These primary sources are transformed into more convenient energy forms, such as electricity or heat when they are harnessed. These energies become https://leonardogiombini.it/2021/07/05/generated-post non-renewable sources of energy once they have been exhausted.
Many fossil fuels, as well as some of the 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 of the earth. Hydraulic fracturing (fracking) can cause earthquakes and water pollution. The combustion of coal releases carbon dioxide, which contributes to global warming.
Fortunately, many of the most promising sources of energy are renewable and sustainable. Wind, solar and hydropower could create, for instance, electricity without digging up new sources.
Tidal and Wave Power are the other renewable energy sources that are gaining popularity. However, in order to be utilized at a large scale these technologies require efficient distribution networks. They need to be constructed and operate with the use of non-renewable energy. These sources aren’t able to meet the majority of our energy demands. However, it’s important to keep in mind that costs for renewable energy equipment have dropped dramatically over the past few years, and efficiency is growing rapidly.
