The World Uses a Variety of Different Energy Sources

The world relies on a https://leonardogiombini.it/2020/09/13/esperienza-consolidata-dalla-sala-riunioni-come-conoscere-le-strategie-di-gestione variety of 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 solar power, wind power biomass, hydroelectricity, and biomass comprise 14 percent. Nuclear energy accounts for another 5 percent. Different countries utilize different sources of energy to meet economic needs and environmental concerns.

Energy is present in nature in many forms: sunlight as well as wind, waves oceans and more. These primary sources can be transformed into more practical energy forms, such as electricity or heat, when they are harnessed. When the energy source is exhausted, they become non-renewable energy sources.

Many fossil fuels as well as some of the other nonrenewable energy sources are damaging the environment. For example, mining for oil can destroy the forests of the planet. Fracking (hydraulic fracturing) could cause water pollution and earthquakes. Carbon dioxide is released when coal is burnt, which contributes to global warming.

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

Other sources of sustainable energy are emerging, such as the wave and tidal power. But, in order to be utilized on a large scale these technologies need effective distribution networks. This requires the use non-renewable energy sources to build these networks. These sources aren’t able to provide the majority of our energy needs. However, it’s important to keep in mind that the costs for renewable energy equipment have come down dramatically over the past couple of years, and efficiency is increasing rapidly.
