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. Renewable sources such as solar energy, wind power biomass, hydroelectricity and biomass make up 14 percent. Nuclear energy is another 5 percent. Different countries use different energy sources to balance the needs of their economy and environmental concerns.

Nature’s energy comes in many forms such as wind, sun, waves, and ocean. These primary sources transform into more efficient energy forms, such as electricity or heat when they are harnessed. Once these energies are exhausted, they become non-renewable energy sources.

The environment is harmed by a variety of fossil fuels as well as some other energy sources that aren’t renewable. Oil mining, for example can cause the destruction of our forests of the earth. Hydraulic fracturing (fracking) can cause earthquakes and pollute the https://leonardogiombini.it/2021/12/18/technical-managerial-areas-in-the-civil-infrastructure water. Carbon dioxide is released when coal is burned, which contributes to global warming.

Fortunately, a lot of the most promising sources of energy are renewable and sustainable. Wind, solar and hydropower can create, for instance, electricity without the need to dig up new sources.

Tidal and Wave Power are the other sustainable energy sources that are emerging. But, in order to be used on a massive scale these technologies require efficient distribution networks. These must be built, which requires the use of non-renewable energy sources. These sources aren’t enough to provide the majority of our energy demands. It is important to be aware that prices for renewable energy-related equipment have fallen drastically over the last few years, and the efficiency is increasing rapidly.
