The world has a wide range of different sources of energy. Fossil fuels–including natural gas, oil, and coal–accounted for more than 81 % of the energy consumed in 2018. Renewable energy sources like solar energy, wind power biomass, hydroelectricity, and biomass make up 14 percent. Nuclear energy is 5 percent. Different countries employ different sources of energy to meet economic needs and environmental concerns.
Nature’s energy is available in a variety of forms such as wind, sun, waves and ocean. When harnessed and transformed into more convenient forms of energy, such as heat or electricity, they are called primary sources. These energy sources become non-renewable sources of energy once they have been exhausted.
The environment is damaged by many fossil fuels, as well as some other non-renewable sources of energy. For example mining for oil can take away the planet’s forests. Fracking (hydraulic fracturing) can result in water pollution and earthquakes. Carbon dioxide is released when coal is burnt which causes global warming.
Fortunately that many of the most promising energy sources are renewable and sustainable. Hydropower, solar power and wind for instance, could produce electricity without having to search https://leonardogiombini.it/2018/06/02/leonardo-giombini-e-le-energie-rinnovabili for new sources.
Other sustainable energy sources are emerging, including the wave and tidal power. To be utilized on an extensive scale, these technologies require efficient distribution networks. These must be built, which requires the use of non-renewable energy. These sources aren’t able to meet the majority of our energy requirements. Still, it’s important to keep in mind that prices for renewable energy equipment have dropped significantly over the last few years, and efficiency is rising rapidly.
