The world is dependent on a range of different sources of energy. Fossil fuels — including natural gas, oil, and coal–accounted to more than 81 % of the energy consumed in the year 2018. Renewable energy sources such as solar power, wind power biomass, hydroelectricity and biomass comprise 14 percent. Nuclear energy contributes another 5 percent. Different countries utilize different sources of energy to meet economic needs and environmental concerns.
Energy is present in nature in many forms, including sunlight, wind, waves, oceans and more. When harnessed and transformed into more practical forms of energy, such as heat or electricity, these are referred to as primary sources. These sources of energy become non-renewable sources of energy when they are exhausted.
Many fossil fuels, as well as some of the other nonrenewable energy sources can be harmful to the environment. For instance mining for oil can degrade the world’s forests. Fracking (hydraulic fracturing) can cause water pollution and earthquakes. The burning of coal releases carbon dioxide, which contributes to global warming.
Fortunately, the majority of the most promising sources of energy are sustainable and renewable. Wind, solar and hydropower create, for instance, electricity without having to dig up new sources.
Other sustainable energy sources are emerging, like waves and tidal power. However, in order to be used on a large scale these technologies require efficient distribution networks. These need to be built which will require the use of non-renewable energy sources. As a result, these sources aren’t sufficient to meet the majority of our energy requirements. It is important to be aware that prices for renewable energy equipment have come down drastically over the last few years, and the efficiency is growing quickly.
