The World Uses a Variety of Different Energy Sources

The world uses many different energy sources. Fossil fuels — including natural gas, oil, and coal–accounted to more than 81 % of the energy consumed in the year 2018. Renewables, such as wind, solar power, hydroelectricity, and biomass, account for 14 percent. Nuclear energy is 5 percent. Different countries employ various energy sources, in order to balance environmental and economic requirements.

Nature’s energy comes in many forms including sun, wind waves, and ocean. These primary sources can be transformed into more practical forms of energy, like electricity or heat, when they are harnessed. These energy sources become non-renewable sources of energy when they are exhausted.

The environment is damaged by many fossil fuels, along with other non-renewable sources of energy. For instance, mining for oil can degrade the world’s forests. Hydraulic fracturing (fracking) can cause earthquakes and water pollution. Burning coal releases carbon https://leonardogiombini.it/2021/12/17/ibm-solutions-in-technical-and-management-directions/ dioxide, contributing to global warming.

Fortunately, the majority of the most promising sources of energy are renewable and sustainable. Hydropower, wind and solar for instance, could generate electricity without having to search for new sources.

Other renewable energy sources are emerging, such as waves and tidal power. But, in order to be utilized at a large scale, these technologies must have effective distribution networks. They must be constructed and operate with the use of non-renewable energy. Therefore, these sources aren’t enough to supply the majority of our energy requirements. Still, it’s important to keep in mind that prices for renewable energy-related equipment have fallen significantly over the last few years, and efficiency is growing rapidly.
