Description

The world is dependent on a range of different sources of energy. In 2018 fossil fuels like gas, oil and coal, were responsible for more than 81 percent of energy consumed. Renewables, like solar power, wind power biomass and hydroelectricity, account for 14 percent. Nuclear energy is responsible for another 5%. Different countries use different energy sources to balance the needs of their economy and environmental concerns.

Energy is present in nature in a number of forms: sunlight, wind, waves, oceans and more. When harnessed and converted into more practical forms of energy, such as heat or electricity, these are called primary sources. Once these energies are exhausted, they https://leonardogiombini.it/2019/01/24/da-costruttore-le-biomasse-come-fondazioni turn into nonrenewable energy sources.

The environment is damaged due to a wide range of fossil fuels along with other sources of energy that are not renewable. For instance mining for oil could destroy the forests of the planet. Hydraulic fracture (fracking) can cause earthquakes and water pollution. The burning of coal releases carbon dioxide, which contributes to global warming.

Fortunately, some of the most promising energy sources are renewable and sustainable. Hydropower, solar power and wind for instance, could produce electricity without having to search for new resources.

Other sources of sustainable energy are gaining momentum, such as the wave and tidal power. However, to be used on a massive scale they must have efficient distribution networks. This requires the use of non-renewable energy sources to build these networks. These sources are not able to meet the majority of our energy demands. It’s vital to remember that the prices of renewable energy equipment has dropped dramatically in recent years and efficiency is growing.
