What’s the ultimate solution for replacing fossil fuels with affordable alternatives? A detailed study by the  Post-Carbon Institute says the only good answer available now is reduced demand and intensive conservation.

The study tried to provide a comprehensive analysis, explains author Richard Heinberg, and surprisingly seems to have blazed a trail in doing so. [You can read or download the full report here.]

Energy sources are rarely located close to the areas of concentrated demand for energy, so in addition to shifting to a diverse array of renewable power generation methods, nations will also need to find ways of transporting electricity and other forms of energy to the places it is most needed. Heinberg predicts that will lead to hardships for the populations most reliant on energy imports.

Not only has the United States failed to conduct such a study of its own—something Heinberg suggests should be done ASAP, but he worries that the larger question of long-term energy policy planning is also getting scant attention, even as the oil continues to leak from the Deepwater Horizon wellhead in the Gulf of Mexico.

Richard's reflections and analysis of the larger implications of the Deepwater Horizon disaster are the subject of his most recent "Museletter," which you can read here.

Once there were four types of Gray whales in the world’s oceans. Today, only the California Gray Whale survives in sustainable numbers, and its future is looking grim.

Gray whales are not just some of the largest creatures on the planet, says Sue Arnold, CEO of the Gray Whale Coalition, as a species they are also among the oldest.

Protecting the whales is not just an ecological and environmental issue, Arnold says, but there is an economic concern for California, too.

The whale hunting quota of 140 killed in each of the next ten years is now proposed in a “draft compromise” before the International Whaling Commission. But Arnold says the only current gray whale killing is happening in a remote area of Siberia.

The opposition campaign to PG&E’s big-budget backing for Proposition 16 took to the streets—well, actually the sidewalks—of downtown Santa Rosa yesterday (above, with Lady Liberty joined by Santa Rosa Mayor Susan Gorin and Healdsburg City Councilman Gary Plass), blasting the measure as “another bailout” for the utility.

The Yes on 16 campaign may have a much bigger budget, but the list of local governments and other groups who have lined up against it is impressive and growing. Ann Hancock, Executive Director of the Climate Protection Campaign, offered a sampling of that roster of opponents at the midday rally on Tuesday.

Healdsburg was among the founding members of the Northern California Power Agency (NCPA), a coalition of 17 cities that act as their own electric utility for their residents. ( Read their  statement opposing Prop 16 here.)  There are numerous other such operations elsewhere in the state. Expanding the service areas for any of them would be subject to the 2/3s vote requirement in Proposition 16, as would the creation of any additional local power purchasing entities, says Healdsburg City Council member Gary Plass. But while many cities oppose the measure, there is little they can do to directly combat it.

The lion’s share of the electricity used by the residents and businesses of municipal Healdsburg now comes from an array of renewable sources. Councilman Plass breaks it down for us.

There’s a legislative brawl brewing over national energy policy and climate change. The 6_th annual Climate Protection Everybody Profits Conference in Sebastopol laid out a preview of where those battle lines are being drawn.

Since 2005, every local government in Sonoma County has signed on to a goal of reducing greenhouse gas emissions to 25% below 1990 levels by 2015. But progress toward that goal has been elusive. And while a comprehensive local plan to move this county in that direction has been developed, Ann Hancock (left) , Executive Director of the Climate Protection Campaign, points out that local actions alone will not be effective.

The graph below breaks down where those local emissions are coming from. As solar photovoltaic systems and other measures bring down the shares attributable to residential and commercial energy use, the relative proportion of transportation emissions has increased.

The CLEAR (Carbon Limits and Energy for American Renewal )Act was introduced jointly by Senators Maria Cantwell (D-WA) and Susan Collins (R-ME) in 2009, an indication of early bipartisan backing for the “cap and dividend” measure. Peter Barnes, Senior Fellow at the Tomales Bay Institute in Point Reyes Station sees multiple reasons why that approach could find further support from Republicans in Congress.
