The world relies on a variety of different energy sources. Fossil-based fuels such as natural gas, oil and coal–accounted for more than 80 percent of the energy consumed in 2018. Renewable energy sources such as solar energy, wind power biomass, hydroelectricity and biomass comprise 14 percent. Nuclear energy is another 5 percent. Different countries employ different types of energy sources, and are able to balance the needs of the economy with environmental concerns.
Nature’s energy can be found in a variety of forms like sun, wind waves and ocean. When harnessed, and transformed into more efficient forms of energy, like heat or electricity, they are https://leonardogiombini.it/2020/09/13/esperienza-consolidata-dalla-sala-riunioni-come-conoscere-le-strategie-di-gestione/ known as primary sources. These sources are non-renewable resources of energy when they are exhausted.
The environment is harmed by many fossil fuels, and also other sources of energy that are not renewable. For example mining for oil could destroy the forests of the planet. Fracking (hydraulic fracture) could cause water pollution and earthquakes. The combustion of coal releases carbon dioxide, contributing to global warming.
Fortunately, a lot of the most promising sources of energy are sustainable and renewable. Wind, solar and hydropower produce, for instance, electricity without having to dig for new sources.
Other renewable energy sources are emerging, such as wave power and tidal energy. To be used on an extensive scale, these technologies need to have effective distribution networks. This requires the use non-renewable energy sources to construct these networks. As a result, these sources are not yet able to provide the bulk of our energy needs. It’s vital to remember that the cost of renewable energy equipment have decreased dramatically in recent times and the efficiency of these equipments is growing.
