The world is awash with 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 such as solar energy, wind power biomass, hydroelectricity and biomass comprise 14 percent. Nuclear energy is responsible for another 5%. Different countries employ different types of energy sources, while https://leonardogiombini.it/2019/03/01/le-biomasse-i-processi-termochimici/ balancing the environmental aspects with economics.

Energy is found in nature in a number of forms: sunlight as well as wind, waves oceans, and more. When harnessed and converted into more convenient forms of energy, like heat or electricity, they are called primary sources. When those energies are exhausted, they become nonrenewable energy sources.

The environment is damaged by many fossil fuels, and also other non-renewable sources of energy. Oil mining, for instance, can destroy the forests of the earth. Hydraulic fracturing (fracking) can cause earthquakes and water pollution. Carbon dioxide is released when coal is burned which causes global warming.

Fortunately there are many promising energy sources are renewable and sustainable. Hydropower, solar energy and wind power, for instance, can produce electricity without the need to dig for new supplies.

Tidal and Wave Power are two more sustainable energy sources that are emerging. However, to be used on a massive scale these technologies need effective distribution networks. This requires the use of non-renewable energy sources to build these networks. These sources aren’t enough to fulfill the majority of our energy requirements. It’s still important to remember that the prices of renewable energy equipment has decreased dramatically in recent times and the efficiency of these equipments is growing.
