Energy vs. per-capita GDP
From Climate change: ‘Berkeley has a special obligation’.
Agricultural and Resource Economics economist David Roland-Holst's chart — which one of his graduate students calls his 'demonic bubble bath' — shows the tight relationship between energy use and prosperity, a key climate change issue. Based on World Bank and International Energy Agency data, the vertical axis plots per capita energy use in terajoules/year; the horizontal is per capita income as measured by the GDP. Bubble sizes represent population.
