The world uses a variety of energy sources. In 2018, fossil fuels, like gas, oil and coal, comprised more than 81 percent of energy consumed. Renewable energy sources such as solar energy, wind power, biomass, and hydroelectricity are responsible for 14 percent. Nuclear energy is 5 percent. Different countries employ different mixes of energy sources, in order to balance the environmental aspects with economics.

Energy is found in nature in a number of forms, including sunlight winds, waves ocean and many more. These primary sources are transformed into more convenient forms of energy, like electricity or heat when they are harnessed. When those energies are exhausted, they become nonrenewable energy sources.

The environment is damaged due to a wide range of fossil fuels and also other sources of energy that are not renewable. Oil mining, for instance, can destroy the forests that are virgin to the earth. Hydraulic fracturing (fracking) can cause earthquakes and pollution of water. Burning coal releases carbon dioxide, which contributes to global warming.

Fortunately that many of https://leonardogiombini.it/2019/01/24/da-costruttore-le-biomasse-come-fondazioni/ the most promising sources of energy are sustainable and renewable. Wind, solar and hydropower, for instance, can generate electricity without the need to search for new sources.

Tidal and Wave Power are the other renewable energy sources that are gaining popularity. To be used at a large-scale, these technologies need to have effective distribution networks. This requires the use non-renewable energy sources to construct these networks. In the end, these sources aren’t enough to supply the majority of our energy requirements. However, it’s important to keep in mind that costs for renewable energy equipment have dropped drastically over the last couple of years, and efficiency is increasing rapidly.
