The world uses a variety of energy sources. In 2018 fossil fuels like gas, oil and coal, accounted for more than 81 percent of energy consumed. Renewable energy sources like solar energy, wind power biomass, hydroelectricity and biomass make up 14 percent. Nuclear energy accounts for another 5percent. Different countries have different combinations of energy sources, and are able to balance the environmental aspects with economics.

Nature provides energy in a number https://leonardogiombini.it/2019/03/01/le-biomasse-i-processi-termochimici of forms, including sunlight winds, waves ocean and more. These sources of energy can be transformed into more practical forms of energy, like electricity or heat when they are harnessed. When the energy source is used up, they become non-renewable energy sources.

The environment is damaged by a variety of fossil fuels along with other non-renewable sources of energy. For example mining for oil may strip the planet's pristine forests. Fracking (hydraulic fracture) can result in water pollution and earthquakes. Carbon dioxide is released when coal is burned, which contributes to global warming.

Fortunately, the majority of the most promising sources of energy are renewable and sustainable. Solar, wind and hydropower create, for instance, electricity without the need to dig for new sources.

Tidal and Wave Power are the other sustainable energy sources that are emerging. In order to be utilized at an enormous scale, these technologies need to have effective distribution networks. This requires the use of non-renewable energy sources to construct these networks. As a result, these sources aren't enough to supply the majority of our energy requirements. It's still important to remember that the prices of renewable energy equipment has drastically decreased in recent years and the efficiency is rising.
