The world is awash with a variety of energy sources. Fossil-based fuels such as natural gas, oil and https://leonardogiombini.it/2021/12/17/ibm-solutions-in-technical-and-management-directions/ coal–accounted for over 81 % of the energy consumed in the year 2018. Renewable energy sources such as wind power, solar energy biomass, hydroelectricity, and wind power make up 14 percent. Nuclear energy is responsible for another 5%. Different countries employ different types of energy sources, in order to balance environmental and economic requirements.
Nature’s energy can be found in a variety of forms such as wind, sun, waves and ocean. When harnessed, and transformed into more practical forms of energy, such as electricity or heat, these are known as primary sources. When those energies are exhausted, they become non-renewable energy sources.
Many fossil fuels as well as some of the other nonrenewable energy sources have been causing environmental harm. For instance, mining for oil can destroy the forests of the planet. Hydraulic fracture (fracking) can trigger earthquakes and pollute the water. Carbon dioxide is released when coal is burnt and contributes to global warming.
Fortunately, a lot of the most promising sources of energy are sustainable and renewable. Wind, solar, and hydropower can create, for instance, electricity without the need to dig for new sources.
Other sources of sustainable energy are emerging, including waves and tidal power. However, in order to be utilized in a large-scale manner these technologies need effective distribution networks. They must be constructed using a source of non-renewable energy. These sources are not able to provide the majority of our energy needs. However, it’s important to keep in mind that the costs for renewable energy equipment have decreased significantly in the past few years, and the efficiency is increasing rapidly.
