Global Growth Rate of GDP and Energy Use
Another slide from Wednesday's opening lecture. It shows the tight correlation between the annual global economic growth rate and the growth rate of energy use. In all but one year, energy use grew more slowly than GDP implying a decline in energy intensity. That year was 2010 - the year of strong rebound growth in the global economy and energy use following the Great Recession in the US and Europe. We analysed these movements in our short 2012 paper in Nature Climate Change.
