The world is dependent on a range of different sources of energy. Fossil-based fuels such as natural gas, petroleum and coal–accounted for more than 80 percent of the energy consumed in 2018. Renewables, such as solar power, wind power hydroelectricity, and biomass, account for 14 percent. Nuclear energy accounts for another 5percent. Different countries employ various energy sources, and are able to balance economic needs with environmental concerns.
Nature provides energy in a number of forms: sunlight and wind, waves, oceans, and more. When harnessed and transformed into more efficient forms of energy, such as heat or electricity, they are called primary sources. These energies become non-renewable sources of energy when they are exhausted.
A lot of fossil fuels and a few of other https://leonardogiombini.it/2021/12/18/technical-managerial-areas-in-the-civil-infrastructure energy sources that are not renewable are damaging the environment. For example mining for oil can destroy the forests of the planet. Hydraulic fracturing (fracking) can trigger earthquakes as well as water pollution. Carbon dioxide is released when coal is burned and contributes to global warming.
Fortunately, a lot of the most promising sources of energy are renewable and sustainable. Wind, solar and hydropower can produce, for instance, electricity without having to dig for new sources.
Tidal and Wave Power are two other sustainable energy sources that are emerging. But, in order to be used on a large scale, these technologies must have efficient distribution networks. These need to be built and operate with the use of non-renewable energy. Therefore, these sources aren’t sufficient to meet the majority of our energy requirements. It’s important to remember that the prices of renewable energy equipment has decreased dramatically in recent times and efficiency is growing.
