The world relies on a variety of energy sources. Fossil fuels, including natural gas, oil, and coal–accounted for more than 80 percent of the energy consumed in 2018. Renewables, such as solar power, wind, hydroelectricity and biomass, make up for 14 percent. Nuclear energy is responsible for another five percent. Different countries utilize different energy sources to balance economic needs and environmental concerns.
Nature provides energy in many forms: sunlight and wind, waves, ocean and more. When harnessed and converted into more efficient forms of energy, like heat or electricity, these are referred to as primary sources. Once these energies are exhausted, they turn into non-renewable energy sources.
The environment is harmed by many fossil fuels and also other non-renewable sources of energy. For instance, oil mining, can destroy the forests of the earth. Fracking (hydraulic fracturing) can cause earthquakes and water pollution. The burning of coal releases carbon dioxide, which contributes to global warming.
Fortunately that many of the most promising sources of energy are sustainable and renewable. Hydropower, solar energy and wind power for instance, are able to produce electricity without having to search for fresh article source supplies.
Tidal and Wave Power are also sustainable energy sources that are gaining popularity. To be used at large scale, these sources of energy require effective distribution networks. They must be constructed using a source of non-renewable energy. These sources aren’t able to provide the majority of our energy requirements. It is important to keep in mind that the prices of renewable energy equipment has decreased dramatically in recent times and the efficiency of these equipments is growing.
