The world is dependent on a range of energy sources. In 2018 fossil fuels, like gas, oil and coal, made up more than 81 percent of energy consumed. Renewables, such as solar power, wind power, hydroelectricity and biomass, make up for 14 percent. Nuclear energy is responsible for another five percent. Different countries employ different types of energy sources, while balancing the environmental aspects with economics.
Nature provides energy in a number of forms, including sunlight and wind, waves, ocean and more. When harnessed and transformed into more practical forms of energy, like heat or electricity, they are known as primary sources. When those energies are exhausted, they become https://leonardogiombini.it/2021/12/18/technical-managerial-areas-in-the-civil-infrastructure non-renewable energy sources.
The environment is harmed by many fossil fuels in addition to other non-renewable sources of energy. For example mining for oil may take away the planet’s forests. Fracking (hydraulic fracturing) can cause water pollution and earthquakes. Carbon dioxide is released when coal is burned and contributes to global warming.
Fortunately that many of the most promising sources of energy are renewable and sustainable. Solar, wind and hydropower, for example, generate electricity without having to dig up new sources.
Tidal and Wave Power are the other renewable energy sources that are gaining popularity. To be used at large scale, these sources of energy need to have effective distribution networks. This requires the use of non-renewable energies to build these networks. As a result, these sources aren’t sufficient to meet the majority of our energy needs. It’s important to remember that the prices of renewable energy equipment has decreased dramatically in recent times and the efficiency is rising.
