The world relies on a variety of energy sources. Fossil fuels, including natural gas, oil, and coal–accounted to more than 81 percent of all energy consumed in the year 2018. Renewables, such as wind, solar power, hydroelectricity and biomass, make up for 14 percent. Nuclear energy accounts for another 5 percent. Different countries employ different types of energy sources, in order to balance environmental and economic requirements.
Nature provides energy in many forms, including sunlight as well as wind, waves ocean and more. When harnessed, and transformed into more convenient forms of energy, like heat or electricity, these are referred to as primary sources. These energies become non-renewable sources of energy when they are exhausted.
The environment is damaged by a variety of fossil fuels along with other energy sources that aren’t renewable. For instance, oil mining is a destructive process that can destroy the forest ecosystems of the planet. Hydraulic fracturing (fracking) can trigger earthquakes and pollute the water. Carbon dioxide is released when coal is burned which causes global warming.
Fortunately some 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.
Tidal and Wave Power are two more sustainable energy sources that are emerging. In order to be utilized at an extensive scale, these technologies need to have effective distribution networks. This requires the use non-renewable energy sources to construct these networks. This means that these sources aren’t sufficient to meet the majority of our energy needs. It is important to keep https://leonardogiombini.it/2020/09/13/esperienza-consolidata-dalla-sala-riunioni-come-conoscere-le-strategie-di-gestione in mind that costs for renewable energy-related equipment have fallen significantly over the last few years, and efficiency is rising rapidly.
