The world has been trying to reduce CO2 emissions to stop climate change. The International Energy Agency (IEA) recently suggested that we will need to generate 88% of our electricity from renewable energy to achieve our goal.

The circle graph below shows suggested electricity generation by energy sources in 2050.

  1. What percentage will fossil fuels (coal, oil & natural gas) make up in 2050 to stop climate change?


Answer 2%

100 – 88 – 2 – 8 = 2(%)
