The World Uses a Variety of Different Energy Sources

The world is awash with a variety of energy sources. In 2018 fossil fuels such as oil, gas and coal, were responsible for more than 81 percent energy consumed. Renewables, like wind, solar power, hydroelectricity and biomass, make up for 14 percent. Nuclear energy accounts https://leonardogiombini.it/2021/07/05/generated-post/ for another 5 percent. Different countries utilize different sources of energy to meet the environmental and economic demands.

Nature’s energy comes in many forms such as wind, sun, waves and ocean. When harnessed, and transformed into more efficient forms of energy, like electricity or heat, these are known as primary sources. When those energies are used up, they become non-renewable energy sources.

The environment is harmed by a variety of fossil fuels as well as some other non-renewable sources of energy. For example, mining for oil can destroy the forests of the planet. Fracking (hydraulic fracture) could cause earthquakes and water pollution. Carbon dioxide is released when coal is burnt, which contributes to global warming.

Fortunately there are many promising sources of energy are renewable and sustainable. Hydropower, wind and solar, for instance, can generate electricity without the need to search for new resources.

Other renewable energy sources are gaining momentum, such as waves and tidal power. In order to be utilized at large scale, these sources of energy need to have effective distribution networks. These need to be built, which requires the use of non-renewable energy. These sources aren’t enough to satisfy the majority of our energy needs. But it’s important be aware that prices for renewable energy-related equipment have fallen significantly in the past couple of years, and efficiency is increasing rapidly.
