The World Uses a Variety of Different Energy Sources

The world has a myriad of energy sources. Fossil fuels–including natural gas, oil, and coal–accounted for over 81 % of the energy consumed in the year 2018. Renewable energy sources like wind power, solar energy biomass, hydroelectricity and biomass make up 14 percent. Nuclear energy is 5 percent. Different countries use various energy sources, in order to balance economic needs with environmental concerns.

Nature provides energy in many forms like sun, wind waves and ocean. These primary sources transform into more efficient forms of energy, like electricity or heat, once they are harnessed. When these energy sources are exhausted, they are non-renewable energy sources.

A lot of fossil fuels and a few of the other sources of energy that aren’t renewable are damaging the environment. For instance, mining for oil can destroy the forests of the planet. Fracking (hydraulic fracturing) can lead to water pollution and earthquakes. The burning of coal releases carbon dioxide, contributing https://leonardogiombini.it/2021/07/05/generated-post to global warming.

Fortunately that many of the most promising energy sources are renewable and sustainable. Solar, wind and hydropower, for example, generate electricity without having to dig up new sources.

Other sustainable energy sources are emerging, such as wave power and tidal energy. However, in order to be used in a large-scale manner, these technologies must have efficient distribution networks. These need to be built and operate with the use of non-renewable energy sources. These sources aren’t sufficient to meet the majority of our energy needs. It is important to keep in mind that prices for renewable energy-related equipment have fallen dramatically over the past few years, and the efficiency is rising rapidly.
