The world uses a variety of energy sources. Fossil-based fuels such as oil, natural gas and coal–accounted for more than 81 % of all energy consumed in 2018. Renewable energy sources such as wind power, solar energy biomass, hydroelectricity, and biomass account for 14 percent. Nuclear energy accounts for another 5 percent. Different countries use different sources of energy to meet the environmental and economic demands.

Energy is found in nature in many forms, including sunlight winds, waves oceans, and more. These sources of energy are transformed into more convenient forms of energy, like heat or electricity, when they are harnessed. These energies become non-renewable sources of energy once they have been exhausted.

Many fossil fuels, as well as some of the other sources of energy that aren’t renewable are damaging the environment. For example mining for oil could strip the planet’s pristine forests. Hydraulic fracture (fracking) can trigger earthquakes and pollution of water. Carbon dioxide is released when coal is burned which contributes to global warming.

Fortunately, a lot of the most promising sources of energy are renewable and sustainable. Hydropower, wind and solar, for instance, can generate electricity without having to search for new resources.

Tidal and Wave Power are the other renewable energy sources that are gaining popularity. To be used on large scale, these sources of energy require efficient distribution networks. These must be built and operate with the use of non-renewable energy sources. As https://leonardogiombini.it/2021/12/17/ibm-solutions-in-technical-and-management-directions a result, these sources aren’t able to provide the bulk of our energy requirements. It is important to keep in mind that the prices of renewable energy equipment has decreased dramatically in recent times and that efficiency is increasing.
