During yesterday’s Sustainable Industries Economic Forum, keynote speaker Paul Hawken suggested that it will take a somewhat monumental effort to get back to 350 ppm in our atmosphere (we’re at 387 right now). His list was daunting.  We’d need one new olympic sized pool of bioalgae fuel production every second for 25 years, for example.  He said that while being a ‘doomer’ has a negative connotation, the facts are the facts, and that there is a role for this kind of startling statistic.  An audience member asked the question that was on all our minds:  “It seems untenable.  Do you have hope that this can actually happen?”

The normally conservative International Energy Agency is now saying that we must act faster to prevent climate change. Not only to prevent catastrophe, but also because the longer we wait, the more difficult and expensive it becomes to achieve the greater and greater cuts that are necessary to keep worldwide temperature rise to 2 degrees Centigrade or a 3.8 degrees Fahrenheit global average.

2 C is the least we can realistically hope and aim for now. This would be less disastrous than the 4 C or the completely catastrophic 6 C (10.8 F) average worldwide temperature rise we would headed for under a business-as-usual continuation of current overall trends in carbon emissions.

Faith Birol, the IEA Chief Economist at the International Energy Agency said that the world must speed up the reduction in fossil energy use and make a transition faster to clean renewable energy, not only because because of climate change but because of growing problems within our energy system and possible implications for the global economy.

What would have been the Southern Hemisphere’s largest wind farm, a $2 billion NZD ($1.4 billion USD) and 630 MW wind farm in New Zealand, is not happening because New Zealand’s Environment Court says that it would ruin the surrounding landscape.

This project would have powered over a million homes and made a huge dent in New Zealand’s greenhouse gas emissions. It is not happening now because of a group of NIMBY activists and the Environment Court’s ruling.

This is a huge blow, in itself, to renewable and wind energy proponents, but it also brings concerns for future wind energy projects.

An inter-agency work group headed by the White House Office of Management and Budget is trying to find the real cost of a ton of carbon emitted. It turns out to be a hard number to agree on.

Would our grandchildren really miss Florida if it was under water? How about no more fruit or nuts from California? What about the loss of our breadbasket? Would the end of corn and soy from the Midwest really bother the grandchildren of our children? How much?

Cost/benefit analysis. Economists do it all the time. So, just what is the cost to society of a ton of carbon?  The Institute for Policy Integrity consulted 144 top economists and released the result: (pdf) Economists and Climate Change: Consensus and Open Questions. By sensibly limiting the sample to economists with the most expertise on climate change, the survey was able to avoid the ignorance of economists who have not studied climate change.

84 percent agreed that the environmental effects of greenhouse gas emissions, as described by leading scientific experts, create significant risks to important sectors of the United States and global economies. A near unanimous 98 percent agreed that putting a price on carbon through a tax or cap-and-trade will increase incentives for efficiency and innovation. 55% preferred a tax, and 35% preferred cap-and‐trade.

But they came up with very widely divergent numbers for both the costs and the benefits. The cost estimates ranged from $10 a to $10 million a ton, with a median of $50 a ton. The benefits of prevention also ranged between $383 billion and $5.5 trillion over the next five decades.

Maldives, one of the most beautiful nations on earth, held the artistic, theatrical event of an underwater government meeting last month, to try to bring more attention to the threats of climate change. Now, they are getting more practical but still grabbing headlines — they are looking to build a wind farm that will generate 40% of the island nation’s electricity needs.

The wind farm plans were announced earlier this week. The project will include 30 turbines and is expected to provide the nation with 75 MW of power, powering the capital city, their international airport, and more!

SolarReserve; a California start-up spin-out from United Technologies’ Rocketdyne has filed an application with the CPUC to build a 150-megawatt heliostat solar farm with seven hours of after-sunset energy stored in molten salt. These are the rocket scientists responsible for our solar-powered space exploration.

Theirs would be the first heliostat type of solar array to produce grid power in California. Abengoa has several in Spain, and plans one in Arizona. United Technologies has licensed the original technology to the new company SolarReserve and its wholly owned subsidiary Rice Solar Energy, LLC, (RSE).

We are actually the second planet-altering species. Three billion years ago, Cyanobacteria were the first. They totally changed this planet to one that is safe for oxygen breathers. That was a big change for species at the time, and most species didn’t make it. Nearly all of them went extinct.

If we’re lucky, we won’t change our environment as much as Cyanobacteria did.  That’s the goal of the US Department of Energy ARPA-E. Inspired by the success of the Defense Advanced Research Projects Agency; ARPA-E will fund high-risk, high-reward advances with the potential to completely change the way our species generates and consumes energy.

Arizona State’s Wim Vermass was of the 37 recipients of the DOE ARPA-E funding. He is teaching the ancient species to make our future fuel and to custom-make it just the way our species wants it.

As the Senate version of pending climate legislations, Kerry-Boxer’s CEJAPA, heads for mark-up on Tuesday, voices calling for $15 billion annually for clean energy research and development are starting to gain traction. Earlier this week, Google’s Director of Climate Change and Energy, Dan Reicher joined the ranks of think tanks such as, Brookings Institution, Third Way, and the Breakthrough Institute, not to mention President Barack Obama, when he called on the Senate EPW committee to include this funding in the bill.

According to Reicher’s testimony (emphasis in original):

“Chairman Boxer, it is essential that Congress address this serious energy R&D short-fall by incorporating President Obama’s goal of $15 billion per year in federal energy R&D spending in final climate legislation.”

This testimony followed on the heals of a letter and discussion paper from the nation’s leading universities to Senate Majority Leader Harry Reid, emphasizing the need for a bottom line investment of $5 billion dollars annually in R&D, significantly more than would be allocated under both House and Senate version of climate and energy legislation.

A very detailed and complex study (pdf) Increasing Wind Energy’s Contribution to the US Electricity Supply weighing the costs and benefits of increasing wind power to 20% by 2030 included some very interesting projections on bird extinction numbers expected from climate change.

While it may not be news to cleantechnica readers that climate change will kill more members of more species than wind turbines, it is interesting to see the actual figures comparing bird loss from climate change versus from wind turbines.

The study found at least 950 entire species of terrestrial birds that will be threatened with extinction as a result of climate change under several scenarios, even at the lower estimate of temperature gains, just counting species of non-sea birds in the higher latitudes; outside the tropics.

There has been a lot of discussion over the last few years about biofuels and whether or not they are actually green, especially when produced on a large, global level.

A new study led by Marine Biological Laboratory (MBL) senior scientist Jerry Melillo says no, they aren’t green (when it comes to climate change). However, there are still many important factors to keep in mind before claiming this is the end of a long and complicated discussion.
