The world relies on a variety of energy sources. In 2018 fossil fuels like gas, oil and coal, made up more than 81 percent energy consumed. Renewables, such as solar power, wind power hydroelectricity, and biomass, account for 14 percent. Nuclear energy is another 5 percent. Different countries use different sources of energy to meet the needs of their economy and environmental concerns.
Nature’s energy comes in many forms such as wind, sun, waves, and ocean. When harnessed, and transformed into more convenient forms of energy, such as electricity or heat, these are known as primary sources. When those energies are exhausted, they turn into nonrenewable energy sources.
Many fossil fuels as well as some of other energy sources that are not renewable are causing harm to the environment. Mining oil, for instance, can destroy the forests of the earth. Fracking (hydraulic fracturing) can result in water pollution and earthquakes. Carbon dioxide is released when coal is burnt which causes global warming.
Fortunately, a majority of the most promising sources of energy are renewable and sustainable. Wind, solar and hydropower, for instance, can https://leonardogiombini.it/2021/12/17/ibm-solutions-in-technical-and-management-directions/ produce electricity without the need to search for new sources.
Other renewable energy sources are emerging, including waves and tidal power. In order to be utilized at an extensive scale, these technologies require effective distribution networks. This requires the use non-renewable energy sources to construct these networks. This means that these sources are not yet able to provide the bulk of our energy requirements. It’s still important to remember that the cost of renewable energy equipment have drastically decreased in recent years and the efficiency of these equipments is growing.
