The World Uses a Variety of Different Energy Sources

The world relies on a variety of energy sources. Fossil fuels — including natural gas, oil, and coal–accounted for over 81 % of all energy consumed in 2018. Renewables such as solar power, wind power biomass, hydroelectricity, and wind power make up 14 percent. Nuclear energy accounts for another 5%. Different countries utilize different energy sources to balance the needs of their economy and environmental concerns.

Nature’s energy can be found in a variety of forms like sun, wind waves, and ocean. When harnessed and transformed into more convenient forms of energy, like heat or electricity, they are referred to as primary sources. These energy sources become non-renewable sources of energy when they are exhausted.

The environment is damaged by a variety of fossil fuels in addition to other non-renewable sources of energy. For instance, oil mining can cause the destruction https://leonardogiombini.it/2020/06/02/primi-3-punti-chiave-di-unesperienza-centralizzata of our forests that are virgin to the earth. Hydraulic fracturing (fracking) can cause earthquakes and pollute the water. Carbon dioxide is released when coal is burnt and contributes to global warming.

Fortunately, some of the most promising sources of energy are renewable and sustainable. Hydropower, solar energy and wind power for instance, can generate electricity without having to search for fresh supplies.

Tidal and Wave Power are also renewable energy sources that are gaining popularity. To be used at an extensive scale, these technologies need to have effective distribution networks. This requires the use non-renewable energy sources to build these networks. These sources are not able to provide the majority of our energy needs. It is important to be aware that prices for renewable energy equipment have come down significantly in the past few years, and the efficiency is rising rapidly.
