IPCC Special Report on Renewable Energy Sources and Climate Change Mitigation (SRREN)

May 11, 2011

This month the IPCC will release its Special Report on Renewable Energy Sources and Climate Change Mitigation. For now, only the Summary for PolicyMakers (SPM) is available; the full report will follow May 31st.

From the Press Release:

Ramon Pichs, Co-Chair of the Working Group III: “The report shows that it is not the availability of the resource, but the public policies that will either expand or constrain renewable energy development over the coming decades. Developing countries have an important stake in this future—this is where most of the 1.4 billion people without access to electricity live yet also where some of the best conditions exist for renewable energy deployment.”

This is also where the impacts of climate change are expected to be most severe.

While the report concludes that the proportion of renewable energy will likely increase even without enabling policies, past experience has shown that the largest increases come with concerted policy efforts.

Though in some cases renewable energy technologies are already economically competitive, the production costs are currently often higher than market energy prices. However, if environmental impacts such as emissions of pollutants and greenhouse gases were monetized and included in energy prices, more renewable energy technologies may become economically attractive.

Technology and solutions

November 9, 2010

To avoid other threads from being overriden by discussions on technology issues, here’s a semi-open thread for those topics.

A few references:

Mark Jacobson’s review of solutions to global warming, air pollution, and energy security, comparing electric, hydrogen (both from a variety of primary energy sources) and biofuel powered transport.

SkepticalScience moving into solutions. John Cook captures my own sentiment very well: “My views on various solution strategies are not as well formed as my views on the attribution of climate change.” Lots of learning to do. Their first post leans heavily on the idea of stabilization wedges by Pacala and Socolow.

There are tons of documents outlining strategies to achieve a low carbon economy. E.g. Roadmap 2050 from the European Climate Foundation, I discussed the Shell energy scenario’s previously, IPCC wgIII, . I’ll update this list when I have more time on my hands.

Joe Romm has a lot of useful things to say about sustainable technologies (as even noted Joe Romm critic Tom Fuller admits). To avoid getting stuck in the details or in overly adversarial posts, perhaps best to go to an overview post such as this or that first.

Previous posts of mine somewhat related to technology and/or solutions. Some other threads also evolved into interesting technology discussions, but I can’t locate them at the moment (which shows the use of keeping discussions on topic).

Topics on my to-write-about list regarding technologies are geoengineering (based on e.g. chapter 6 from my hand in this report, which starts with an overview of mitigation options before exploring some in more detail), the indirect land use effect of biomass (e.g. chapter 3.3. of the same report) and perhaps transport.
