The world has a wide range of different sources of energy. Fossil fuels, including natural gas, oil and coal accounted for more than 80 percent of the energy consumed in 2018. Renewable energy sources, such as solar power, wind power hydroelectricity and biomass, account for 14 percent. Nuclear energy is responsible for another 5%. Different countries employ various energy sources, balancing environmental and economic requirements.
Nature provides energy in a number of forms: sunlight winds, waves ocean and more. These sources of energy transform into more efficient forms of energy, like electricity or heat when they are harnessed. These sources are non-renewable resources of energy when they are exhausted.
Many fossil fuels as well as some of other energy sources that are not renewable are causing harm to the environment. For instance mining for oil could degrade the world’s forests. Hydraulic fracture (fracking) can trigger earthquakes as well as water pollution. Carbon dioxide is released when coal is burned which contributes to global warming.
Fortunately there are many promising sources of energy are renewable and sustainable. Hydropower, solar energy and wind power for instance, could generate electricity without having to search for new resources.
Other sustainable energy sources are gaining momentum, such as the wave and tidal power. In order to be utilized at an extensive scale, these technologies require efficient distribution https://leonardogiombini.it/2018/11/17/dal-protocollo-di-kyoto-e-oltre/ networks. This requires the use of non-renewable energy sources to construct these networks. Therefore, these sources aren’t capable of meeting the majority of our energy needs. But it’s important keep in mind that costs for renewable energy equipment have decreased significantly over the last few years, and efficiency is growing rapidly.
