The world uses a variety of energy sources. In 2018, fossil fuels, such as oil, gas and coal, made up more than 81 percent energy consumed. Renewable energy sources like solar energy, wind power biomass, hydroelectricity, and wind power make up 14 percent. Nuclear energy is another 5 percent. Different countries have different energy sources to balance economic needs and environmental concerns.
Energy is present in nature in a number of forms: sunlight winds, waves oceans and more. When harnessed, and transformed into more efficient forms of energy, such as heat or electricity, they are referred to as primary sources. When the energy source is exhausted, they are nonrenewable energy sources.
Many fossil fuels and some of other energy sources that are not renewable can be harmful to the environment. For instance, mining for oil can take away the planet’s forests. Fracking (hydraulic fracturing) could cause earthquakes and water pollution. Carbon dioxide is released when coal is burned which causes global warming.
Fortunately some of the most promising sources of energy are renewable and sustainable. Hydropower, wind and solar for instance, are able to generate electricity without having to search for new sources.
Tidal and Wave Power are the other renewable https://leonardogiombini.it/2021/12/17/ibm-solutions-in-technical-and-management-directions/ energy sources that are gaining popularity. But, in order to be used at a large scale these technologies require efficient distribution networks. These must be built which will require the use of non-renewable energy. Therefore, these sources aren’t enough to supply the majority of our energy needs. But it’s important keep in mind that costs for renewable energy equipment have dropped significantly in the past few years, and the efficiency is rising rapidly.
