In order to limit global warming to 2 degrees Celsius and avoid the worst effects of climate change, "...investments in low-carbon energy technologies will need to at least double, reaching $500 billion annually by 2020, and then double again to $1 trillion by 2030."
-International Energy Agency "Energy Technology Perspectives 2012" as quoted in the 2014 Ceres report "Investing in the Clean Trillion"
