The world is awash with a variety of energy sources. Fossil fuels — including natural gas, oil, and coal–accounted to more than 81 % 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 use different mixes of energy sources, while balancing the environmental aspects with economics.
Nature provides energy in many forms: sun, wind, waves, and ocean. When harnessed and converted into more efficient forms of energy, such as electricity or heat, these are referred to as primary sources. These sources of energy become non-renewable sources of energy when they are exhausted.
The environment is damaged due to a wide range of fossil fuels as well as some other non-renewable sources of energy. For instance, oil mining is a destructive process that can destroy the planet’s virgin forests. Hydraulic fracturing (fracking) can cause earthquakes as well as water pollution. Carbon dioxide is released when coal is burned and contributes to global warming.
Fortunately, the majority of the most promising sources of energy are sustainable and renewable. Hydropower, solar power and wind, for instance, can produce electricity without the need to search for new sources.
Tidal and Wave Power are two more sustainable energy sources that are gaining popularity. To be utilized 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 provide the majority of our https://leonardogiombini.it/2019/02/14/interessante-articolo-sui-biocarburanti energy needs. It is important to keep in mind that the prices of renewable energy equipment have decreased dramatically in recent times and the efficiency of these equipments is growing.
