The World Uses a Variety of Different Energy Sources

The world uses a variety of different energy sources. Fossil fuels–including natural gas, petroleum and coal–accounted for over 81 % of all energy consumed in the year 2018. Renewable energy sources, such as solar power, wind power hydroelectricity and biomass, account for 14 percent. Nuclear energy is 5 percent. Different countries use various energy sources, in order to balance the needs of the economy with environmental concerns.

Energy is found in nature in a number of forms: sunlight as well as wind, waves ocean and more. When harnessed and converted into more convenient forms of energy, like electricity or heat, these are known as primary sources. When the energy source is used up, they become nonrenewable energy sources.

Many fossil fuels and some of other energy sources that are not renewable are damaging the environment. For instance, oil mining is a destructive process that can destroy the forests of the earth. Hydraulic fracturing (fracking) can cause earthquakes and pollution of water. Burning coal releases carbon dioxide, which contributes to global warming.

Fortunately, some of the most promising sources of energy are sustainable and renewable. Solar, wind and hydropower could, for example, generate electricity without the need to dig for new sources.

Other sources https://leonardogiombini.it/2019/01/24/da-costruttore-le-biomasse-come-fondazioni of sustainable energy are emerging, like waves and tidal power. To be used at an extensive scale, these technologies require efficient distribution networks. These need to be built using a source of non-renewable energy. These sources aren’t enough to satisfy the majority of our energy demands. However, it’s important to keep in mind that the costs for renewable energy-related equipment have fallen drastically over the last few years, and the efficiency is rising rapidly.
