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 more than 81 percent of energy consumed. Renewable sources such as solar power, wind power biomass, hydroelectricity, and wind power comprise 14 percent. Nuclear energy accounts for another 5%. Different countries have different energy sources to balance environmental and economic requirements.

Nature provides energy in many forms including sun, wind waves and ocean. When harnessed and transformed into more convenient forms of energy, like heat or electricity, they are known as primary sources. These energies become non-renewable sources of energy when they are exhausted.

A lot of fossil fuels and a few of the other sources of energy that aren’t renewable can be harmful to the environment. For instance mining for oil can degrade the world’s forests. Fracking (hydraulic fracturing) can result in water visite site pollution and earthquakes. The burning of coal releases carbon dioxide, contributing 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 up new sources.

Tidal and Wave Power are two more renewable energy sources that are emerging. To be used on an extensive scale, these technologies require efficient distribution networks. These need to be built and operate with the use of non-renewable energy sources. In the end, these sources are not yet sufficient to meet the majority of our energy needs. It is important to keep in mind that the prices of renewable energy equipment have fallen dramatically in recent years and the efficiency of these equipments is growing.
