Flood myths are common to human culture. Swollen
rivers, tidal storms, and tsunamis make their appearance frequently in
literature. But Hurricane Sandy, which has drawn newly etched high-water marks
on the buildings of lower Manhattan (and Brooklyn), has shifted the discussion from storytelling to
reality.
Volatility in climate has drawn the attention of
policy makers for a decade. But as so often is the case, a dramatic event like
superstorm Sandy – the largest storm to hit New York since the colonial era – has punctured the psyche of the densely
populated East Coast, including the New York-Washington, DC axis where U.S.
policy is made.
Not surprisingly, in the weeks since the historical
hurricane made landfall, new attention is being paid to the mounting costs that
coastal world megacities may face.
Intriguingly, however, this new conversation about
climate, energy policy, and America’s reliance on fossil fuels comes after a
five-year period in which the U.S. has dramatically lowered its consumption of
oil and seen an equally dramatic upturn in the growth of renewable energy.
America’s production of CO2 in the first quarter of 2012 fell
to twenty-year lows. The country is using less coal, increasing its use
of natural gas, and (like the rest of the OECD) is seeing its transportation
demand migrate from cars and trucks to rail. While Europe is often cited as
being at the forefront of renewable power, the U.S. has also started to produce
very strong growth ratesfor wind and solar power:
