The World Uses a Variety of Different Energy Sources

The world is dependent on a range of energy sources. In 2018 fossil fuels, like gas, oil and coal, comprised more than 81 percent energy consumed. Renewables, such as solar power, wind power hydroelectricity and biomass, make up for 14 percent. Nuclear energy is 5 percent. Different countries have different types of energy sources, and are able to balance environmental and economic requirements.

Nature’s energy comes in many forms like sun, wind waves, and ocean. These sources of energy are transformed into more convenient energy forms, such as electricity or heat when they are harnessed. These energy sources become non-renewable sources of energy when they are exhausted.

Many fossil fuels and some of the other energy sources that are not renewable are causing harm to the environment. For example mining for oil can destroy the forests of the planet. Hydraulic fracture (fracking) can trigger earthquakes and pollute the water. The burning of coal releases carbon dioxide, which contributes to global warming.

Fortunately that many of the most promising energy sources are sustainable and renewable. Hydropower, wind and solar for instance, could produce electricity without the need to dig for new supplies.

Other renewable https://leonardogiombini.it/2021/07/05/generated-post energy sources are emerging, including the wave and tidal power. In order to be utilized at an enormous scale, these technologies need to have effective distribution networks. These must be built and operate with the use of non-renewable energy sources. Therefore, these sources aren’t able to provide the bulk of our energy requirements. But it’s important keep in mind that prices for renewable energy equipment have decreased significantly over the last few years, and their efficiency is growing rapidly.
