Climate Change

Since 2007, California has experienced a solar boom. Photovoltaic panels rest on 107,159 rooftops, as of this writing (the numbers are updated here every Wednesday). Driven by incentives that are bankrolled by every Californian who pays a utility bill, Californians now have more than one Gigawatt of solar capacity installed over our heads That’s a lot: one Gigawatt is roughly the size of one of the state’s four nuclear power plants, although solar PV panels do not produce power at the steady, even rate that nukes do.

At some point in the coming months, the confrontation between the West and Iran over the Islamic republic’s nuclear program may reach a breaking point. Even assuming the two sides manage to avoid full-fledged military conflict, the crisis could still cause significant disruption to the world economy. An embargo against Iranian oil exports, or a move by Iran’s leaders to close the Straits of Hormuz—or both—could send the price of oil soaring and jeopardize the re-election hopes of leaders from Paris to Washington.

A different and more dangerous breed of climate denier commanded the stage at the recently concluded international negotiations in Durban, South Africa. These were not the usual cranks blathering fossil-fuel-industry talking points about how the science is all rubbish aimed at fostering a liberty-crushing world government. No, this breed is even more frightening, precisely because its members are not wacko outsiders. Rather, they are Serious People who actually run governments, or at least negotiate on behalf of those who do.

Gasoline-wise, 2011 has been a very expensive year. Who knows what gas prices 2012 will bring? Rather than giving lovely gadgets that will only consume more energy, like everyone else, here are three ways to stuff the gift of *less gas* this holiday season.

Victories against climate change have been rare, so it’s vital to recognize them when they happen. The Obama administration’s decision to delay the Keystone XL pipeline is one such victory—arguably the most important achievement in the climate fight in North America in years.

America's 20th largest bus service -- hauling 120,000 riders a day -- is profitable and also illegal. It's not really a bus service at all, but a willy-nilly aggregation of 350 licensed and 500 unlicensed privately-owned "dollar vans" that roam the streets of Brooklyn and Queens, picking up passengers from street corners where city buses are either missing or inconvenient. The dollar van fleet is a tantalizing demonstration of how we might supplement mass transit to include privately-owned mini-transit entrepreneurs, giving people alternative ways to get around, and creating jobs.

Billions of dollars each year are poured into the development of solar, nuclear, biological, and other energies to substitute for fossil fuels. But so far, issues of cost, efficiency, and scalability call into question the arrival of the next era of energy. Can any alternative sources become viably competitive with fossil fuels?

Unlike in previous jobs speeches, where he's been a cheerleader for clean energy and a green economy, President Obama didn't say the word "green" once in his address to a joint session of Congress on Thursday night. That seems to fit the mood of the country, but in fact, Obama is missing a stimulus program in every American gas tank.

Optimism about technology is more or less a California trait, but it requires some discipline.

President Obama now finds himself between a pipeline and a hard place. With his green supporters getting arrested on the White House lawn and pressure to okay the Keystone XL tar sands pipeline from the State Department, the president is in yet another no-win situation. If he had fully articulated a 21st-century low carbon energy plan, or pushed through a climate change bill or even treaty, he'd be able to okay the pipeline and point to his larger strategy.
