Now is absolutely the time to politicize Hurricane Irma and other natural disasters

“Hurricane Katrina overwhelmed levees and exploded the conventional wisdom about a shared American prosperity, exposing a group of people so poor they didn’t have $50 for a bus ticket out of town. If we want to learn something from this disaster, the lesson ought to be: America’s poor deserve better than this.” - Michael Eric Dyson


This past weekend, Hurricane Irma made landfall in the United States, battering the entire state of Florida with a colossal reach of more than 400 miles. Making landfall as a category 4 hurricane, with sustained winds in excess of 130 miles per hour (209 km/hr), causing massive flooding and storm surges, resulting in more than five million power outages, and even creating catastrophic tornadoes, the damage it caused may well rise into the hundreds of billions of dollars. This occurred on the heels of Hurricane Harvey, which made landfall in and around Houston, Texas, as a category 4 hurricane as well, marking the first time in recorded history that two hurricanes as powerful as category 4 made landfall in the same year in the United States.

The trillion dollar question: will renewables displace natural gas?

A recent story on Bloomberg News, “What If Big Oil’s Bet on Gas Is Wrong?”, challenges the conventional wisdom that demand for natural gas will grow as it displaces coal and facilitates the growth of renewable energy sources like wind and solar power. Instead, the forecast highlighted in the article envisions gas’s global share of electricity dropping from 23% to 16% by 2040 as renewables shoot past it. So much for gas as the “bridge to the future” if that proves accurate.

‘Battery improvements depend on chemistry, not semiconductor electronics. Assuming their costs can continue to fall like those for solar cells looks questionable’


Several points in the story leave room for doubt. For starters, this projection from Bloomberg New Energy Finance (BNEF), the renewables-focused analytical arm of Bloomberg, would leave coal with a larger share of power generation than gas in 2040, when it has renewables reaching 50%. That might make sense in the European context on which their forecast seems to be based, but it flies against the US experience of coal losing 18 points of electricity market share since 2007 (from 48.5% to 30.4%), with two-thirds of that drop picked up by gas and one-third by expanding renewables. (See chart below.)
