The world has a myriad of energy sources. Fossil-based fuels such as natural gas, oil, and coal–accounted for over 81 percent of all energy consumed in 2018. Renewables such as solar power, wind power biomass, hydroelectricity and biomass account for 14 percent. Nuclear energy is responsible for another five percent. Different countries have different sources of energy to meet the needs of their economy and environmental concerns.

Nature’s energy comes in many forms: sun, wind, waves and ocean. These sources of energy transform into more efficient energy forms, such as electricity or heat when they are harnessed. Once these energies are used up, they become non-renewable energy sources.

The environment is damaged due to a wide range of fossil fuels along with other energy sources that aren’t renewable. Mining oil, for instance, can destroy the forests of the earth. Hydraulic fracture (fracking) can cause earthquakes and pollute the water. The burning of coal releases carbon dioxide, which contributes to global warming.

Fortunately that many of the most promising leonardogiombini.it sources of energy are renewable and sustainable. Hydropower, wind and solar for instance, can produce electricity without having to search for fresh supplies.

Tidal and Wave Power are the other sustainable energy sources that are emerging. To be used at a large-scale, these technologies require efficient distribution networks. This requires the use of non-renewable energy sources to build these networks. These sources aren’t able to meet the majority of our energy demands. It’s still important to remember that the prices of renewable energy equipment has dropped dramatically in recent years and the efficiency is rising.
