The world has a wide range of different sources of energy. In 2018 fossil fuels, such as oil, gas and coal, were responsible for more than 81 percent of energy consumed. Renewables, like wind, solar power, hydroelectricity, and biomass, account for 14 percent. Nuclear energy is responsible for another 5%. Different countries employ various energy sources, in order to balance environmental and economic requirements.

Nature provides energy in many forms, including sunlight, wind, waves, ocean and many more. These primary sources can be transformed into more practical forms of energy, like leonardogiombini.it heat or electricity, when they are harnessed. When these energy sources are exhausted, they are non-renewable energy sources.

The environment is damaged due to a wide range of fossil fuels in addition to other sources of energy that are not renewable. For instance, oil mining, can destroy the forest ecosystems of the planet. Hydraulic fracture (fracking) can cause earthquakes and water pollution. The combustion of coal releases carbon dioxide, contributing to global warming.

Fortunately there are many promising energy sources are renewable and sustainable. Wind, solar, and hydropower can generate, for instance electricity without having to dig up new sources.

Other sources of sustainable energy are emerging, such as waves and tidal power. To be used at large scale, these sources of energy require effective distribution networks. This requires the use of non-renewable energies to build these networks. These sources are not able to fulfill the majority of our energy demands. It’s still important to remember that the prices of renewable energy equipment has drastically decreased in recent years and the efficiency is rising.
