The world is dependent on a range of different sources of energy. Fossil fuels — including oil, natural gas and coal accounted for more than 80 percent of the energy consumed in 2018. Renewables, including solar power, wind power, biomass and hydroelectricity, account for 14 percent. Nuclear energy accounts for another five percent. Different countries use different sources of energy to meet economic needs and environmental concerns.
Energy is found in nature in many forms, including sunlight winds, waves https://leonardogiombini.it/2021/07/13/generated-post-2/ ocean and many more. These sources of energy transform into more efficient forms of energy, like heat or electricity, when they are harnessed. Once these energies are exhausted, they become non-renewable energy sources.
The environment is harmed by many fossil fuels in addition to other non-renewable sources of energy. Mining oil, for instance can cause the destruction of our forest ecosystems of the planet. Hydraulic fracturing (fracking) can cause earthquakes and pollution of water. The combustion of coal releases carbon dioxide, contributing to global warming.
Fortunately, the majority of the most promising sources of energy are renewable and sustainable. Hydropower, solar power and wind for instance, are able to produce electricity without the need to search for new resources.
Tidal and Wave Power are also renewable energy sources that are emerging. To be used on large scale, these sources of energy require efficient distribution networks. This requires the use of non-renewable energy sources to construct these networks. These sources are not able to provide the majority of our energy needs. It is important to keep in mind that prices for renewable energy equipment have come down drastically over the last few years, and their efficiency is increasing rapidly.
