The world has a myriad of energy sources. Fossil fuels — including natural gas, oil, and coal–accounted for more than 81 % of the energy consumed in 2018. Renewable energy sources such as solar energy, wind power biomass, hydroelectricity and biomass make up 14 percent. Nuclear energy accounts for another 5%. Different countries have different mixes of energy sources, balancing economic needs with environmental concerns.
Nature is a rich source of energy in a number of forms, including sunlight and wind, waves, ocean and more. These primary sources transform into more efficient energy forms, such as electricity or heat, when they are harnessed. When these energy sources are exhausted, they become nonrenewable energy sources.
Many fossil fuels, as well as some of the other energy sources that are not renewable are causing harm to the environment. Oil mining, for instance is a destructive process that can destroy the forests of the earth. Fracking (hydraulic fracture) can lead to water pollution and earthquakes. The combustion of coal releases carbon dioxide, contributing to global warming.
Fortunately, some of the most promising energy sources are sustainable and renewable. Wind, solar and hydropower for instance, could generate electricity without the need to dig for https://leonardogiombini.it/2019/03/01/le-biomasse-i-processi-termochimici new supplies.
Tidal and Wave Power are two other renewable energy sources that are gaining popularity. To be utilized on an enormous scale, these technologies require efficient distribution networks. These need to be built and operate with the use of non-renewable energy. These sources aren’t sufficient to fulfill the majority of our energy demands. It’s important to remember that the prices of renewable energy equipment have drastically decreased in recent years and that efficiency is increasing.
