The world is dependent on a range of different energy sources. Fossil fuels — including oil, natural gas and coal–accounted for more than 80 percent of the energy consumed in 2018. Renewables, including solar power, wind power, hydroelectricity and biomass, make up for 14 percent. Nuclear energy is another 5 percent. Different countries employ different mixes of energy sources, while balancing economic needs with environmental concerns.

Nature’s energy comes 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 energy sources become non-renewable sources of energy when they are exhausted.

The environment is harmed by a variety of fossil fuels in addition to other energy sources that aren’t renewable. For instance, oil mining, can destroy the forests of the earth. Fracking (hydraulic fracture) can lead to earthquakes and water pollution. Carbon dioxide is released when coal is burned which causes global warming.

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

Other sustainable energy sources are emerging, including the wave and tidal power. However, in order to be used at a large scale they must have efficient distribution networks. They need to be constructed and operate with the use of non-renewable energy sources. These sources aren’t able to meet the majority of our energy demands. But it’s important be aware that prices for renewable energy equipment have decreased significantly over the last couple of years, and efficiency is growing rapidly.
