Global warming concerns everybody because it triggers climate change or the long-term change in the average weather patterns.
Not a small problem
The world needed 600 EJ (ExaJoules of energy) in 2019. So what is an ExaJoule? It is an energy unit, which equals 1018 Joules (1 followed by 18 zeros). To put it in perspective, the energy consumed by your 10 W LED bulb in one hour is 36000 Joules. Another unit to describe energy is TWh (terawatt hour). 600 EJ is approximately 167,000 TWh.
So, what is the issue with this energy? Out of this 600, 490 are directly connected to CO2 emissions. Or that energy is produced by burning fuels containing carbon atoms in it – you call it coal, crude oil or natural gas. Let’s look at the split in the year 2019.
Oil | Coal | Natural Gas | Biofuels | Nuclear | Hydro | Wind Solar |
187 | 162 | 140 | 57 | 30 | 15 | 13 |
