The World Uses a Variety of Different Energy Sources

The world uses many different 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, hydroelectricity and biomass, make up for 14 percent. Nuclear energy contributes another 5 percent. Different countries employ different sources of energy to meet economic needs and environmental concerns.

Nature’s energy is available 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, these are referred to as primary sources. These sources are non-renewable resources of energy when they are exhausted.

The environment is harmed by many fossil fuels, in addition to other non-renewable sources of energy. Oil mining, for instance can devastate the planet’s virgin forests. Hydraulic fracturing (fracking) can trigger earthquakes and pollution of water. Burning coal releases carbon dioxide, which contributes to global warming.

Fortunately, some of the most promising energy sources are sustainable and renewable. Wind, solar and hydropower can generate, for instance electricity without having to dig up new sources.

Tidal and Wave Power are two more sustainable energy sources that are gaining popularity. But, in order to be utilized on a large scale, these technologies must have efficient distribution networks. They must be constructed which will require the use of non-renewable energy sources. In the end, these sources are not yet enough to supply the majority of our energy requirements. It’s important to remember that the prices of renewable energy equipment have dropped dramatically in recent years and the continue reading this efficiency is rising.
