The world uses a variety of energy sources. In 2018 fossil fuels, such as oil, gas and coal, made up more than 81 percent of energy consumed. Renewable sources such as solar energy, wind power biomass, hydroelectricity, and biomass make up 14 percent. Nuclear energy accounts for another five percent. Different countries have different types of energy sources, and are https://leonardogiombini.it/2019/01/24/da-costruttore-le-biomasse-come-fondazioni able to balance the needs of the economy with environmental concerns.
Nature’s energy comes in many forms: sun, wind, waves, and ocean. These sources of energy can be transformed into more practical energy forms, such as electricity or heat, when they are harnessed. These energy sources become non-renewable sources of energy when they are exhausted.
The environment is damaged due to a wide range of fossil fuels as well as some other non-renewable sources of energy. Oil mining, for instance can cause the destruction of our forest ecosystems of the planet. Hydraulic fracture (fracking) can trigger earthquakes as well as water pollution. Carbon dioxide is released when coal is burnt and contributes to global warming.
Fortunately, some of the most promising energy sources are renewable and sustainable. Wind, solar and hydropower generate, for instance electricity without the need to dig for new sources.
Tidal and Wave Power are also renewable energy sources that are gaining popularity. However, to be utilized in a large-scale manner these technologies need efficient distribution networks. These need to be built and operate with the use of non-renewable energy. These sources aren’t enough to provide 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 that efficiency is increasing.
