The World Uses a Variety of Different Energy Sources

wpis w: Uncategorized | 0

The world has a myriad of energy sources. Fossil fuels, including natural gas, oil and coal accounted for more than 81 % of the energy consumed in 2018. Renewables, such as wind, solar power, hydroelectricity, and biomass, account for 14 percent. Nuclear energy is 5 percent. Different countries have various energy sources, balancing economic needs with environmental concerns.

Nature provides energy in many forms: sunlight, wind, waves, ocean and more. When harnessed and converted into more convenient forms of energy, such as heat or electricity, they are known as primary sources. When those energies are exhausted, they are nonrenewable energy sources.

The environment is harmed by many fossil fuels, as well as some other sources of energy that are not https://leonardogiombini.it/2021/11/29/top-vdr-providers-which-come-with-247-support-for-all-deal-makers renewable. For instance mining for oil may strip the planet’s pristine forests. Hydraulic fracturing (fracking) can cause earthquakes and pollute the water. 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. Solar, wind and hydropower can create, for instance, electricity without having to dig for new sources.

Tidal and Wave Power are also sustainable energy sources that are emerging. But, in order to be used on a massive scale, these technologies must have effective distribution networks. This requires the use non-renewable energy sources to build these networks. In the end, these sources aren’t enough to supply the majority of our energy requirements. Still, it’s important to keep in mind that the costs for renewable energy equipment have dropped significantly over the last few years, and their efficiency is increasing rapidly.
