Most consumed fuel typesAlthough many governments have set up targets for substituting and phasing out coal, the fossil fuel remains the second most important source for worldwide final energy consumption after oil. By comparison, clean energy sources such as biomass and electricity account for around 20 percent of final energy use. Following the Fukushima disaster, nuclear energy consumption experienced a slump between 2011 and 2012, before growing again over the following years. Some governments such as China have championed the use of nuclear energy alongside renewables to better chances of assuaging climate change.
Renewable energy consumption has grown three-fold in the past decade as countries scramble to reduce their carbon footprint and deployment of solar and wind tech has become more affordable.
