The World Uses a Variety of Different Energy Sources

The world relies on a variety of different energy sources. Fossil fuels, including natural gas, oil, and coal accounted for more than 80 percent of the energy consumed in the year 2018. Renewables such as solar power, wind power technical-mechanic areas in the civil engineering field biomass, hydroelectricity, and wind power are responsible for 14 percent. Nuclear energy accounts for another five percent. Different countries have different mixes of energy sources, while balancing economic needs with environmental concerns.

Nature’s energy can be found in a variety of forms such as wind, sun, waves, and ocean. These sources of energy transform into more efficient energy forms, such as electricity or heat, once they are harnessed. When the energy source is exhausted, they turn into non-renewable energy sources.

The environment is damaged by a variety of fossil fuels in addition to other sources of energy that are not renewable. Oil mining, for example is a destructive process that can destroy the forest ecosystems of the planet. Hydraulic fracture (fracking) can trigger earthquakes and pollute the water. The burning of coal releases carbon dioxide, which contributes to global warming.

Fortunately there are many promising sources of energy are renewable and sustainable. Wind, solar and hydropower can, for example, generate electricity without having to dig for new sources.

Tidal and Wave Power are two other sustainable energy sources that are gaining popularity. In order to be utilized at a large-scale, these technologies require effective distribution networks. This requires the use non-renewable energy sources to construct these networks. These sources aren’t sufficient to provide the majority of our energy demands. However, it’s important to keep in mind that costs for renewable energy-related equipment have fallen significantly over the last couple of years, and efficiency is increasing rapidly.
