The world is dependent on a range of energy sources. In 2018 fossil fuels, such as oil, gas and coal, comprised more than 81 percent energy consumed. Renewable energy sources such as wind power, solar energy biomass, hydroelectricity and biomass comprise 14 percent. Nuclear energy is 5 percent. Different countries utilize different sources of energy to meet environmental and economic requirements.

Nature provides energy in a number of forms: sunlight as well as wind, waves oceans and more. These sources of energy are transformed into more convenient forms https://leonardogiombini.it/2018/06/02/leonardo-giombini-e-le-energie-rinnovabili of energy, like electricity or heat, once they are harnessed. These sources of energy become non-renewable sources of energy when they are exhausted.

The environment is damaged by a variety of fossil fuels and also other non-renewable sources of energy. For instance, oil mining, can destroy the forest ecosystems of the planet. Fracking (hydraulic fracture) can lead to earthquakes and water pollution. Carbon dioxide is released when coal is burnt which contributes to global warming.

Fortunately there are many promising energy sources are renewable and sustainable. Hydropower, wind and solar for instance, are able to generate electricity without the need to search for new sources.

Other renewable energy sources are emerging, including tidal and wave power. In order to be utilized at an extensive scale, these technologies need to have effective distribution networks. These need to be built which will require the use of non-renewable energy sources. Therefore, these sources aren’t sufficient to meet the majority of our energy needs. It’s still important to remember that the prices of renewable energy equipment have decreased dramatically in recent times and efficiency is growing.
