The world has a wide range of different energy sources. Fossil fuels–including oil, natural gas and coal accounted for more than 80 percent of the energy consumed in the year 2018. Renewable energy sources such as wind power, solar energy biomass, hydroelectricity, and biomass account for 14 percent. Nuclear energy is 5 percent. Different countries employ different combinations of energy sources, while balancing the environmental aspects with economics.
Nature is a rich source of energy in a number of forms: sunlight and wind, waves, ocean and more. These primary sources transform into more efficient forms of energy, like electricity or heat, when they are harnessed. Once these energies are used up, they become non-renewable energy sources.
A lot of fossil fuels and a few of other energy sources that https://leonardogiombini.it/2021/12/18/technical-managerial-areas-in-the-civil-infrastructure/ are not renewable can be harmful to the environment. For instance mining for oil may degrade the world’s forests. Fracking (hydraulic fracturing) can cause water pollution and earthquakes. Burning coal releases carbon dioxide, contributing to global warming.
Fortunately some of the most promising energy sources are renewable and sustainable. Wind, solar and hydropower can create, for instance, electricity without having to dig up new sources.
Tidal and Wave Power are the other sustainable energy sources that are emerging. However, to be used in a large-scale manner these technologies need effective distribution networks. This requires the use non-renewable energy sources to construct these networks. These sources aren’t able to fulfill the majority of our energy needs. But it’s important keep in mind that prices for renewable energy equipment have come down drastically over the last couple of years, and efficiency is increasing rapidly.
