The world uses a variety of energy sources. Fossil-based fuels such as natural gas, oil and coal–accounted for over 80 percent of the energy consumed in the year 2018. Renewables, such as wind, solar power, hydroelectricity, and biomass, account for 14 percent. Nuclear energy accounts for another 5percent. Different countries have different combinations of energy sources, and are able to balance the needs of the economy with environmental ibm solutions in technical and management directions concerns.
Nature’s energy can be found in a variety of forms: sun, wind, waves, and ocean. These primary sources can be transformed into more practical forms of energy, like electricity or heat when they are harnessed. When these energy sources are used up, they become nonrenewable energy sources.
Many fossil fuels, as well as some of other energy sources that are not renewable are damaging the environment. For instance, oil mining is a destructive process that can destroy the forest ecosystems of the planet. Hydraulic fracturing (fracking) can cause earthquakes and pollution of water. Carbon dioxide is released when coal is burned, which contributes to global warming.
Fortunately, a lot of the most promising sources of energy are renewable and sustainable. Hydropower, solar power and wind, for instance, can produce electricity without the need to search for new sources.
Tidal and Wave Power are two more sustainable energy sources that are gaining popularity. To be used at an enormous scale, these technologies require effective distribution networks. They need to be constructed which will require the use of non-renewable energy sources. These sources aren’t able to satisfy the majority of our energy requirements. However, it’s important to keep in mind that costs for renewable energy equipment have decreased significantly over the last few years, and their efficiency is rising rapidly.
