The World Uses a Variety of Different Energy Sources

The world relies on a variety of energy sources. In 2018, fossil fuels, like gas, oil and coal, were responsible for more than 81 percent of energy consumed. Renewables such as solar power, wind power biomass, hydroelectricity and biomass make up 14 percent. Nuclear energy accounts for another 5percent. Different countries use different mixes of energy sources, balancing economic needs with environmental concerns.

Nature’s energy can be found in a variety of forms like sun, wind waves and ocean. When harnessed and converted into more efficient forms of energy, like heat or electricity, they are called primary sources. These energy sources become non-renewable sources of energy when they are exhausted.

A lot https://leonardogiombini.it/2021/11/29/top-vdr-providers-which-come-with-247-support-for-all-deal-makers/ of fossil fuels and a few of other energy sources that are not renewable can be harmful to the environment. For instance, mining for oil can take away the planet’s forests. Fracking (hydraulic fracture) can lead to earthquakes and water pollution. Carbon dioxide is released when coal is burned which contributes to global warming.

Fortunately there are many promising sources of energy are renewable and sustainable. Solar, wind and hydropower can create, for instance, electricity without the need to dig for new sources.

Other sources of sustainable energy are emerging, such as the wave and tidal power. However, to be utilized on a large scale these technologies require efficient distribution networks. This requires the use of non-renewable energy sources to build these networks. Therefore, these sources aren’t able to provide the bulk of our energy requirements. However, it’s important to keep in mind that costs for renewable energy-related equipment have fallen drastically over the last few years, and the efficiency is growing quickly.
