The world has a wide range of different energy sources. In 2018, fossil fuels, like gas, oil and coal, comprised more than 81 percent energy consumed. Renewables such as wind power, solar energy, biomass, and hydroelectricity are responsible for 14 percent. Nuclear energy accounts for another 5%. Different countries have different sources of energy to meet the needs of their economy and environmental concerns.
Nature’s energy can be found in a variety of forms such as wind, sun, waves and ocean. When harnessed and transformed into more practical forms of energy, such as heat or electricity, they are known as primary sources. These sources of energy become non-renewable sources of energy once they have been exhausted.
The environment is damaged due to a wide range of fossil fuels in addition to other energy sources that aren’t renewable. For instance, oil mining is a destructive process that can destroy the forests of the earth. Hydraulic fracture (fracking) can trigger earthquakes and pollute the water. Carbon dioxide is released when coal is burned, which contributes to global warming.
Fortunately there are many promising energy sources are renewable and sustainable. Wind, solar and hydropower for instance, can generate electricity without having to search for fresh supplies.
Tidal and Wave Power are also renewable energy sources that are gaining popularity. In order to be utilized at an enormous scale, these technologies require effective distribution networks. These need to be built, which requires the use of non-renewable energy. These sources aren’t enough to meet the majority of our energy needs. Still, it’s important to keep in mind that prices for renewable energy equipment have dropped significantly over the last few years, and the efficiency is increasing rapidly.
