The world uses many different energy sources. In 2018 fossil fuels like gas, oil and coal, accounted for more than 81 percent energy consumed. Renewable energy sources such as solar power, wind power, biomass, and hydroelectricity make up 14 percent. Nuclear energy is responsible for another five percent. Different countries use different sources of energy to meet the environmental and economic demands.
Nature is a rich source of energy in many forms, including sunlight winds, waves ocean and many more. When harnessed and converted into more efficient forms of energy, like heat or electricity, they are known as primary sources. When these energy sources are used up, they become non-renewable energy sources.
The environment is harmed due to a wide range of fossil fuels and also other energy sources that aren’t renewable. Mining oil, for instance can cause the destruction of our forests of the earth. Fracking (hydraulic fracture) can result leonardo giombini e le energie rinnovabili in earthquakes and water pollution. Carbon dioxide is released when coal is burned and contributes to global warming.
Fortunately, a lot of the most promising sources of energy are renewable and sustainable. Wind, solar and hydropower for instance, could produce electricity without the need to search for new sources.
Other sustainable energy sources are gaining momentum, such as tidal and wave power. In order to be utilized at an extensive scale, these technologies require efficient distribution networks. This requires the use non-renewable energy sources to build these networks. In the end, these sources are not yet able to provide the bulk of our energy needs. But it’s important keep in mind that prices for renewable energy-related equipment have fallen significantly in the past few years, and their efficiency is growing quickly.
