The world relies on a variety of different sources of energy. In 2018, fossil fuels, such as oil, gas and coal, accounted for over 81 percent of the energy consumed. Renewables, including wind, solar power, hydroelectricity and biomass, make up for 14 percent. Nuclear energy accounts for another 5%. Different countries employ different mixes of energy sources, in order to balance the needs of the economy with environmental concerns.
Energy is present in nature in many forms: sunlight and wind, waves, ocean and more. These primary sources can be transformed into more practical forms of energy, like heat or electricity, when they are harnessed. When the energy source is exhausted, they are non-renewable energy sources.
The environment is damaged by many fossil fuels, in addition to other sources of energy that are not renewable. Oil mining, for example can cause the destruction of our planet’s virgin forests. Fracking (hydraulic fracture) can result in water pollution and earthquakes. Carbon dioxide is released when coal is burned, which contributes to global warming.
Fortunately, many of the most promising sources of energy are sustainable and renewable. Wind, solar and hydropower for instance, are able to produce electricity without the need to search for fresh supplies.
Tidal and Wave Power are two more sustainable energy sources that are gaining popularity. However, in order to be utilized on a large scale, these technologies must have effective distribution networks. They must be constructed using a source of non-renewable energy sources. Therefore, these sources are not yet enough to supply the majority of our energy requirements. Still, it’s important to keep in mind that prices for renewable energy equipment have come down dramatically over the past couple of years, and efficiency is rising rapidly.
