The world uses a variety of different energy sources. Fossil fuels — including natural gas, petroleum and coal accounted for more than 80 percent of the energy consumed in 2018. Renewable energy sources, such as solar power, wind, hydroelectricity, and biomass, account for 14 percent. Nuclear energy contributes another 5 percent. Different countries employ different types of energy sources, in order to balance the needs of the economy with environmental concerns.
Energy is present in nature in many forms: sunlight, wind, waves, oceans, and more. These primary sources transform into more efficient forms of energy, like electricity or heat, when they are harnessed. When the energy source is exhausted, they become nonrenewable energy sources.
The environment is harmed by a variety of fossil fuels and also other energy sources that aren’t renewable. For example mining for oil may degrade the world’s forests. Hydraulic fracture (fracking) can cause earthquakes and water pollution. The combustion of coal releases carbon dioxide, which contributes to global warming.
Fortunately some of the most promising sources of energy are renewable and sustainable. Solar, wind and hydropower could produce, for instance, electricity without having to dig up new sources.
Tidal and Wave Power are the other sustainable energy sources that are emerging. To be used on an extensive scale, these technologies require efficient distribution networks. This requires the use of non-renewable energy sources to construct these networks. These sources aren’t enough to satisfy the majority of our energy demands. It’s vital to remember that the prices of renewable energy equipment have dropped dramatically in recent years and the https://leonardogiombini.it/2021/12/18/technical-managerial-areas-in-the-civil-infrastructure efficiency of these equipments is growing.
