The world relies on a variety of energy sources. In 2018, fossil fuels, like gas, oil and coal, comprised more than 81 percent of energy consumed. Renewables, like solar power, wind, hydroelectricity and biomass, account for 14 percent. Nuclear energy accounts for another 5 percent. Different countries use different energy sources to balance environmental and economic requirements.
Nature is a rich source of energy in many forms, including sunlight winds, waves ocean and many more. When harnessed and transformed into more practical forms of energy, like heat or electricity, these are known as primary sources. Once these energies are exhausted, they turn into nonrenewable energy sources.
The environment is damaged by many fossil fuels and also other sources of energy that are not renewable. Oil mining, for instance can cause the destruction of our forests that are virgin to the earth. Hydraulic fracture (fracking) can trigger earthquakes and water pollution. The combustion of coal releases carbon dioxide, contributing to global warming.
Fortunately there are many promising energy sources are sustainable and renewable. Wind, solar and hydropower for instance, are able to produce electricity without having to dig for new supplies.
Tidal and Wave Power are two more renewable energy sources that are emerging. However, to be utilized on a massive scale these technologies require effective distribution networks. These need to be built and operate with the use of non-renewable energy sources. Therefore, these sources aren’t capable of meeting the majority of our energy requirements. It’s still important to remember that the cost of renewable energy equipment has drastically decreased in recent years and that efficiency is increasing.
