The world has a wide range of different sources of energy. Fossil fuels–including oil, natural gas and coal–accounted for more than 81 percent of all energy consumed in 2018. Renewable energy sources, such as wind, solar power, hydroelectricity and biomass, make up for 14 percent. Nuclear energy accounts for another 5percent. Different countries employ different energy sources to balance environmental and economic requirements.
Nature provides energy in many forms such as wind, sun, waves, and ocean. When harnessed and converted into more efficient forms of energy, like https://leonardogiombini.it/2021/07/05/generated-post heat or electricity, these are known as primary sources. These sources of energy become non-renewable sources of energy once they have been exhausted.
The environment is damaged by many fossil fuels and also other non-renewable sources of energy. For instance, oil mining can cause the destruction of our forest ecosystems of the planet. Hydraulic fracture (fracking) can cause earthquakes and pollute the water. Carbon dioxide is released when coal is burned and contributes to global warming.
Fortunately, a majority of the most promising sources of energy are sustainable and renewable. Hydropower, solar energy and wind power for instance, are able to generate electricity without having to dig for new supplies.
Other renewable energy sources are gaining momentum, such as waves and tidal power. However, in order to be utilized on a massive scale these technologies need effective distribution networks. These must be built and operate with the use of non-renewable energy sources. These sources aren’t sufficient to satisfy the majority of our energy needs. It’s still important to remember that the cost of renewable energy equipment has decreased dramatically in recent times and the efficiency is rising.
