The world has a wide i vantaggi delle centrali energetiche range of energy sources. Fossil fuels, including natural gas, petroleum and coal–accounted for over 80 percent of the 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 utilize different energy sources to balance the environmental and economic demands.

Nature’s energy can be found in a variety of forms including sun, wind waves and ocean. These sources of energy transform into more efficient forms of energy, like electricity or heat, when they are harnessed. These energies become non-renewable sources of energy once they have been exhausted.

A lot of fossil fuels and a few of the other energy sources that are not renewable have been causing environmental harm. For instance, oil mining, can destroy the forest ecosystems of the planet. Hydraulic fracture (fracking) can trigger earthquakes as well as water pollution. Burning coal releases carbon dioxide, which contributes to global warming.

Fortunately, a majority of the most promising sources of energy are sustainable and renewable. Solar, wind, and hydropower can, for example, generate electricity without having to dig up new sources.

Tidal and Wave Power are two other renewable energy sources that are gaining popularity. However, to be used in a large-scale manner these technologies need efficient distribution networks. This requires the use of non-renewable energy sources to build these networks. These sources are not able to fulfill the majority of our energy needs. It’s still important to remember that the prices of renewable energy equipment have fallen dramatically in recent years and the efficiency is rising.
