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. Renewable energy sources like solar energy, wind power, biomass, and hydroelectricity comprise 14 percent. Nuclear energy is responsible for another five percent. Different countries employ different types of energy sources, while balancing the environmental aspects with economics.

Nature’s energy comes in many forms: sun, wind, waves, and ocean. These primary sources can be transformed into more practical energy forms, such as electricity or heat, when they are harnessed. When these energy sources are exhausted, they turn into non-renewable energy sources.

Many fossil fuels as well as some of the other sources of energy that aren’t renewable can be harmful to the environment. For instance, mining for oil can take away the planet’s forests. Fracking (hydraulic fracture) can result in water pollution and earthquakes. Burning coal releases carbon dioxide, which contributes to global warming.

Fortunately there are many promising sources of energy are sustainable and renewable. Wind, solar, and hydropower can produce, for instance, electricity without having to dig for new sources.

Tidal and Wave Power are two other renewable energy sources that are emerging. In order to be utilized at an enormous scale, these technologies need to https://leonardogiombini.it/2020/06/02/primi-3-punti-chiave-di-unesperienza-centralizzata/ have effective distribution networks. These need to be built and operate with the use of non-renewable energy. As a result, these sources aren’t enough to supply the majority of our energy requirements. It is important to keep in mind that the prices of renewable energy equipment have decreased dramatically in recent times and efficiency is growing.
