The world is awash with a variety of energy sources. Fossil fuels — including natural gas, oil, and coal accounted for more than 81 % of all energy consumed in 2018. Renewables, including solar power, wind power biomass and hydroelectricity, account for 14 percent. Nuclear energy contributes another 5 percent. Different countries employ different combinations of energy sources, and are able to balance environmental and economic requirements.
Energy is found in nature in a number of forms, including sunlight and wind, waves, oceans, and more. These primary sources are transformed into more convenient forms of energy, like electricity or heat, when they are harnessed. These energies become non-renewable sources of energy once they have been exhausted.
Many fossil fuels as well as some of the other energy sources that are not renewable can be harmful to the environment. For example mining for oil could destroy the forests of the planet. Hydraulic fracture (fracking) can cause earthquakes and pollute the water. Carbon dioxide is released when coal is burnt which contributes 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 fresh supplies.
Tidal and Wave Power are the other sustainable energy sources that are gaining popularity. However, in order to be utilized in a large-scale manner, these technologies must have efficient distribution networks. They must be constructed using a source of non-renewable energy. This https://leonardogiombini.it/ means that these sources are not yet capable of meeting the majority of our energy needs. It is important to keep in mind that the costs for renewable energy-related equipment have fallen significantly over the last few years, and efficiency is rising rapidly.
