The World Uses a Variety of Different Energy Sources
The world relies on a variety of different sources of energy. Fossil fuels, including natural gas, petroleum and coal accounted for more than 81 percent of all energy consumed in 2018. Renewable energy sources, such as wind, solar power, hydroelectricity, and biomass, account for 14 percent. Nuclear energy accounts for another five percent. Different countries have different sources of energy to meet economic needs and environmental concerns.
Nature’s energy comes in many forms such as wind, sun, waves and ocean. These sources of energy are transformed into more convenient energy forms, such as electricity or heat, once they are harnessed. These energy sources become non-renewable sources of energy once they have been exhausted.
Many fossil fuels as well as some of the other sources of energy that aren’t renewable are causing harm to the environment. For example, mining for oil can take away the planet’s forests. Hydraulic fracture (fracking) can trigger earthquakes and pollution of water. The burning of coal releases carbon dioxide, which contributes to global warming.
Fortunately, many of the most promising sources of energy are sustainable and renewable. Hydropower, wind and solar for instance, could generate https://leonardogiombini.it/2021/12/18/technical-managerial-areas-in-the-civil-infrastructure electricity without having to search for new sources.
Tidal and Wave Power are two more renewable energy sources that are gaining popularity. But, in order to be used on a massive scale these technologies need efficient distribution networks. This requires the use non-renewable energies to build these networks. These sources are not able to satisfy the majority of our energy demands. But it’s important keep in mind that prices for renewable energy equipment have decreased significantly in the past few years, and the efficiency is rising rapidly.
