I'm feeling a bit chuffed. After too much time messing around - and Excel for some reason refusing to operate correctly - I successfully made my somewhat complex chart of New York's historic renewable energy production (share of total electricity production), the policy targets that have been set at various times (note that the 2015 target has still not been met), and the steep ramp to meet the wildly optimistic 2030 target (which, in real output terms, is a moving target as the state electrifies everything it can).
My tongue-in-cheek prediction: The 2030 target will be met by radically reducing electricity production in New York. After all, 70% of a lower denominator is a much more achievable goal.
That would crush the economy, take thousands of lives from heat and cold deaths, and not move the needle a smidgeon on global warming, but climate activists could at last claim a real energy policy victory.
My real prediction: The state will fail to meet the target (I see no plausible way in which it can bring that much renewable generation online in 7 years), and climate activists will not even begin to learn that you can't simply mandate huge technological achievements on a tight time table.
