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, accounted for over 81 percent of the energy consumed. Renewable energy sources such as wind power, solar energy biomass, hydroelectricity, and biomass comprise 14 percent. Nuclear energy accounts for another 5 percent. Different countries have various energy sources, and are able to balance 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 transformed into more convenient forms of energy, such as heat or electricity, they are referred to as primary sources. These energy sources become non-renewable sources of energy once they have been exhausted.

Many fossil fuels as well as some of other energy sources that are not renewable are causing harm to the environment. Oil mining, for example is a destructive process that can destroy the forests that are virgin to the earth. Hydraulic fracture (fracking) can cause earthquakes and water pollution. The combustion of coal releases carbon dioxide, which contributes to global warming.

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

Tidal and Wave Power are two more sustainable energy sources that are emerging. However, in order to be utilized on a massive scale these technologies need effective distribution networks. These need to be built, which requires the use of non-renewable energy. Therefore, these sources aren’t capable of meeting the majority of our energy requirements. But it’s important keep in mind that prices for renewable energy equipment have dropped significantly over the last few years, and their efficiency is increasing rapidly.
