The world is awash with a variety of energy sources. In 2018 fossil fuels, such as oil, gas and coal, made up more than 81 percent energy consumed. Renewables, like wind, solar power, hydroelectricity and biomass, make up for 14 percent. Nuclear energy is 5 percent. Different countries utilize different energy sources to balance the needs of their economy and environmental concerns.
Nature is a rich source of energy in many forms: sunlight as well as wind, waves ocean and many more. These sources of energy can be transformed into more practical forms of energy, like electricity or heat when they are harnessed. These sources of energy become non-renewable sources of energy when they are exhausted.
The environment is damaged by many fossil fuels along with other sources of energy that are not renewable. For instance, mining for oil can degrade the world’s forests. Fracking (hydraulic fracturing) can result in water pollution and earthquakes. Carbon dioxide is released when coal is burned, which contributes to global warming.
Fortunately, many of the most promising sources of energy are sustainable and renewable. Hydropower, solar energy and wind power for instance, are able to generate electricity without the need to leonardo giombini e le energie rinnovabili search for fresh supplies.
Tidal and Wave Power are also renewable energy sources that are emerging. To be used on a large-scale, these technologies need to have effective distribution networks. This requires the use of non-renewable energy sources to build these networks. These sources are not able to satisfy the majority of our energy demands. It’s vital to remember that the prices of renewable energy equipment has decreased dramatically in recent times and that efficiency is increasing.
