Business consulting firm projects robust growth for solar and grid parity in many locations by 2020

McKinsey has a great new analysis piece: “The economics of solar power.” Overall it’s extremely optimistic, saying that despite uncertainties around technology and policy, growth in the solar sector is all but certain to be robust. Here’s a interesting chart. The size of the yellow ball is the size of the solar market in TWh. […]

Wimbledon under fire for shooting pigeons

As the Wimbledon tennis championships get underway, the real drama isn’t on the court but in the air. After the players’ lawn and an open-air restaurant were dive-bombed by pigeons, officials sent marksmen to take ’em out. The tournament employs two hawks for pigeon-scaring, “and by and large they do the job,” says a Wimbledon […]

Florida will buy out sugar company to restore Everglades

Nearly 300 square miles of sugar plantation in the Everglades will once again become marsh, as Florida Gov. Charlie Crist announced Tuesday that the state will buy the land from U.S. Sugar Corp. If all goes to plan, the $1.75 billion deal may be the largest environmental restoration in the history of the United States. […]

Even U.S. government says human emissions are changing climate

The U.S. Climate Change Science Program (a.k.a. the Bush Administration) has issued a must-read report, Weather and Climate Extremes in a Changing Climate. It wouldn't be must-read or even big news if it weren't for the fact that

• Many environmentalists stopped talking about the extreme weather/global warming link a decade ago.
• The deniers, the delayers, and of course the Roger Pielkes of the world have pushed back against any claims that climate change is driving the extreme weather we see today. (as Chico Marx (dressed as Groucho) said "Who you gonna believe, me or your own eyes?")
• The media has been brow-beaten by the deniers into downplaying the connection. The journalist Ross Gelbspan has a long discussion of this in his great 2004 book, Boiling Point -- I will blog on this later.
• The Midwest is experiencing the second "500-year flood" in 13 years. (Don't worry, big media, it's all just a big coincidence like the deniers keep saying.)

CNN and clean coal

Virginia’s disappearing mountain Eden

As I reported last week, I'm in Appalachia, Va. to attend a hearing by the Virginia Air Resources Board about whether or not Virginia will permit Dominion Power to build a dirty, coal-fired power plant. It's Eden in the Mountains here -- miles and miles of green, forested mountains in every direction. Inside the forests, it's even better. My wife and I went on a hike through old growth hemlock groves (and did a trail-cleaning service project in the nearby Jefferson National Forest) with naturalist and activist Anna Hess of the Clinch Coalition and learned that this region is the most bio-diverse in the mainland United States, with different little endangered salamanders creeping around the top of every mountain and old growth hemlock groves around many corners.

How to green your vacation

Wherever you go, there you are … still having an impact. Everyone needs to take a break from the stresses of life, and environmentalists are no exception. After all, vacations are a necessary part of any sustainable lifestyle. And while vacation time itself can be hard to come by, your getaway needn’t be hard on […]

Short-term targets key to long-term stabilization

Ken Ward takes a worthwhile look at the goalposts for U.S. climate policy in his argument for making 350 parts per million the new bright line for success. We agree that we need to aim lower than 450 ppm -- the world is at roughly 380 ppm now, and we're already witnessing adverse climate impacts.

But we part ways when it comes to how we're going to get there. Ward suggests that EDF's support for the Lieberman-Warner Climate Security Act can't be reconciled with a stabilization target below 450 ppm, because the bill as written wouldn't drive sufficient emissions reductions. In fact, there's nothing incompatible about the two. Here's why:

Day two of the UN Dispatch-Grist collaboration

Our weeklong collaboration with UN Dispatch rolls on today with a discussion prompted by On Day One user taylorshelton who suggests government subsidies for non-renewable energy should be eliminated.

Eliminate all subsidies for traditional fuels (coal, oil and nuclear) and invest all energy-related funds into renewable energy resources like solar, wind and cellulosic ethanol with the goal of completely eliminating dependence on fossil fuels and nuclear power.

Nigel Purvis, Kate Sheppard, David Roberts, and Timothy B. Hurst respond below the fold.

Mayors resolve to phase out city spending on bottled water

The U.S. Conference of Mayors passed a resolution Monday to phase out city spending on bottled water. “Cities are sending the wrong message about the quality of public water when we spend taxpayer dollars on water in disposable containers from a private corporation,” said San Francisco Mayor Gavin Newsom, adding, “The fact is, our tap […]
