So.... page 54. That's $22.5 trillion dollars over 30 years, or $750b a year for 30 years. The global economy is good for 78 trillion a year by way of comparison, so this is a thousandth of that... but it's not a negligible sum. We're at 100 million barrels of oil per day. Brent crude, today, is $64 per barrel. Right now, all the oil we burn in a year, worldwide, is $2.4 trillion dollars. So we're talking, rough sketch, a 30-40% premium over our current energy costs in order to get onto renewables. For 30 years.
