The World Uses a Variety of Different Energy Sources

description

The world has a myriad of energy sources. Fossil-based fuels such as natural gas, petroleum and coal accounted for more than 81 % of all energy consumed in the year 2018. Renewable energy sources such as wind power, solar energy biomass, hydroelectricity, and wind power comprise 14 percent. Nuclear energy is responsible for another 5%. Different countries employ different sources of energy to meet the environmental and economic demands.

Energy is found in nature in a number of forms, including sunlight winds, waves oceans, and more. When harnessed and converted into more practical forms of energy, like heat or electricity, these are referred to as primary sources. These sources are non-renewable resources of energy once they have been exhausted.

The environment is harmed by many fossil fuels, and also other non-renewable sources of energy. Mining oil, for instance can cause the destruction of our planet’s virgin forests. Fracking (hydraulic fracture) can cause earthquakes and water pollution. Carbon dioxide is released when coal is burnt which causes global warming.

Fortunately, some of the most promising sources of energy are renewable and sustainable. Hydropower, solar energy and wind power for instance, could produce electricity without the need to dig for new supplies.

Other renewable energy sources are gaining momentum, such as wave power and tidal energy. To be utilized on an extensive scale, these technologies require efficient distribution networks. These must be built and operate with the use of non-renewable energy sources. These sources aren’t able to meet the majority of our energy requirements. It’s vital to remember that the prices of renewable energy equipment have dropped dramatically in recent years and the efficiency is rising.
