High-tech sunken tidal turbines

I guess engineers don’t like land-based turbines anymore

Recently, I posted about a Canadian group that created a helium-filled floating wind turbine. On the opposite side of sea level, a Virgina-based team has installed several underwater turbines in New York's East River. Posted today on MIT's Technology Review (a good technology publication btw). Working from barges and tugboats off New York City's Roosevelt Island, engineers are battling northeasters and this month's heavy spring tides to install the first major tidal-power project in the United States. The project involves a set of six submerged turbines that are designed to capture energy from the East River's tidal currents. The three-bladed …

McCain's big speech on energy and climate

A mixed bag

John McCain gave a major speech today in which he said that energy dependence and global warming are major threats to America's future that urgently need to be addressed. The policy section started off with this great bit: Energy efficiency by using improved technology and practicing sensible habits in our homes, businesses and automobiles is a big part of the answer, and is something we can achieve right now. And new advances will make conservation an ever more important part of the solution. Improved light bulbs can use much less energy; smart grid technology can help homeowners and businesses lower …

Green polls reveal lazy bastards

Joel Makower has a fascinating roundup of recent green poll results. He concludes: So, what do we know that we didn't know pre-Earth Day? Not much. It's business as usual: Americans want clean, affordable, and care-free solutions to climate change and every other environmental challenge. But don't ask most of them to change their habits, spend more, or go very far out of their way. But for companies, it's a different story. They're the ones we're looking to for solutions -- for example, to create products, processes, and policies that solve global warming. That is, if global warming turns out …

Plans to boost energy efficiency start getting traction in Congress

What's not to love about energy efficiency? It's the paradigmatic win-win scenario -- save money, protect the climate and broader environment, and reduce reliance on unsavory sources of energy, all in one fell swoop. As efficiency guru Amory Lovins puts it [PDF], "Using energy more efficiently offers an economic bonanza -- not because of the benefits of stopping global warming, but because saving fossil fuel is a lot cheaper than buying it." But until recently, energy efficiency has had about as much sex appeal as, well, Amory Lovins. While Congress has tacked a smattering of appliance efficiency standards onto omnibus …

A functional, global response: Strategy

Environmentalists need to fundamentally change their climate change strategy

Pro-fossil fuel forces are pursuing an effective strategy that engages the attention of climate action advocates and obscures the vigorous expansion of fossil fuel supply now underway. How is it possible for the world's best informed governmental and private sector leaders to proceed with this course of action when the consequences are known? An answer, of sorts, is visible in the business plans and statements of fossil fuel sector leaders. In their view, the effort to reduce fossil fuel use is a fool's errand. It is therefore both profitable and the best climate change strategy to ramp up oil gas …

Barack Tease

Obama pledges to save the civilized world with baby steps "This is our generation's moment to save future generations from global catastrophe," declared Democratic presidential candidate Barack Obama in a speech on Friday. He heralded a "grassroots effort to make America greener and end the tyranny of oil." And just as greens were up on their collective tippie-toes, primed for a collective Obamagasm, he ... proposed a small boost in U.S. vehicle fuel-efficiency standards. Oh. Obama's "National Low Carbon Fuel Standard," which would federalize vehicle emissions standards put forward by California and since adopted by eight other states, would lower …

Vote Surly, Vote Often

Aluminum smelting defining Iceland elections You no doubt know that Iceland's elections are coming up on May 12. But here's something you may not know: the country's aluminum-smelting boom has become a key issue in the race. With three smelters up and running and three more planned, fans and foes alike are fired up. A new party, the Iceland Movement, has a platform with exactly one issue -- a five-year moratorium on big industrial projects while the effects of the current boom are studied -- and the Left Green Party also opposes the smelters. The author of an anti-smelter book …
