The World Uses a Variety of Different Energy Sources

The world is awash with a variety of energy sources. In 2018, fossil fuels, like gas, oil and coal, comprised more than 81 percent energy consumed. Renewables, such as wind, solar power, hydroelectricity, and biomass, account for 14 percent. Nuclear energy is 5 percent. Different countries utilize different sources of energy to meet environmental and economic requirements.

Energy is present in nature in many forms, including sunlight, wind, waves, ocean and more. When harnessed and transformed into more convenient forms of energy, such as heat or electricity, these are called primary sources. These sources of energy become non-renewable sources of energy when they are exhausted.

The environment is damaged by many fossil fuels as well as some other non-renewable sources of energy. For instance mining for oil could degrade the world’s forests. Hydraulic fracturing (fracking) can trigger earthquakes and https://leonardogiombini.it/2020/06/02/primi-3-punti-chiave-di-unesperienza-centralizzata pollute the water. Carbon dioxide is released when coal is burnt, which contributes to global warming.

Fortunately that many of the most promising sources of energy are sustainable and renewable. Hydropower, solar power and wind, for instance, can produce electricity without the need to search for new resources.

Other sustainable energy sources are gaining momentum, such as tidal and wave power. To be utilized on an extensive scale, these technologies require effective distribution networks. This requires the use non-renewable energy sources to construct these networks. These sources are not able to satisfy the majority of our energy demands. It’s still important to remember that the prices of renewable energy equipment has drastically decreased in recent years and the efficiency is rising.
