The world has a myriad of energy sources. Fossil fuels–including oil, natural gas and coal accounted for more than 81 percent of all energy consumed in 2018. Renewable energy sources, such as solar power, wind, biomass and hydroelectricity, account for 14 percent. Nuclear energy is 5 percent. Different countries employ different sources of energy to meet environmental https://leonardogiombini.it/2020/09/13/esperienza-consolidata-dalla-sala-riunioni-come-conoscere-le-strategie-di-gestione/ and economic requirements.
Energy is present in nature in a number of forms, including sunlight winds, waves oceans and more. These sources of energy can be transformed into more practical forms of energy, like electricity or heat, when they are harnessed. When the energy source is exhausted, they become non-renewable energy sources.
The environment is damaged by a variety of fossil fuels as well as some other energy sources that aren’t renewable. For example mining for oil may destroy the forests of the planet. Hydraulic fracture (fracking) can cause earthquakes and pollution of water. Carbon dioxide is released when coal is burned and contributes to global warming.
Fortunately, a majority of the most promising sources of energy are sustainable and renewable. Hydropower, solar energy and wind power for instance, can produce electricity without the need to search for new sources.
Other renewable energy sources are emerging, including the wave and tidal power. However, to be utilized on a large scale these technologies require effective distribution networks. This requires the use of non-renewable energies to build these networks. This means that these sources are not yet sufficient to meet the majority of our energy needs. It is important to keep in mind that the cost of renewable energy equipment have dropped dramatically in recent years and the efficiency is rising.
