For Chapter 10, we took on a thorough review of existing scenarios. ! Driving Questions:
! What sorts of future levels of renewable energy deployment are consistent with different CO2 concentration goals; or, put another way, what is the linkage between CO2 concentration goals and the deployment of renewable energy?
! Which classes of renewable energy will be the most prominent energy producers and how quickly might they expand production?
! Where would an expansion in renewable energy occur? ! What is the linkage between the costs of mitigation and an expansion
of renewable energy? ! The value of the dataset
! Latest scenarios, including delayed participation scenarios and limited technology scenarios.
! Collected data on renewable energy at a more detailed level than in previous assessments.

There is a broad spread of mitigation levels in the dataset.
Imagine how much stronger the story is going to be when we have thousands of scenarios.
![Page 5: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/5.jpg)
Although there is some correlation between renewable deployment and mitigation level, there is enormous uncertainty.
![Page 6: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/6.jpg)
Primary energy is not all that linked to stabilization level.
![Page 7: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/7.jpg)
Fossil energy is tightly correlated to fossil and industrial CO2 emissions.
![Page 8: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/8.jpg)
Low-carbon energy is far less correlated, because of energy demand.
![Page 9: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/9.jpg)
Looking only at renewable energy adds the uncertainty of competition between nuclear and CCS.
![Page 10: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/10.jpg)
Maybe the deployment of renewable energy is just a function of whether nuclear and CCS are available.
![Page 11: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/11.jpg)
But that is clearly not the whole story.
![Page 12: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/12.jpg)
The increase in costs from limiting renewables is comparable to the increase from limiting other technologies.
![Page 13: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/13.jpg)

There is no correlation between carbon prices and renewable energy deployment levels
![Page 15: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/15.jpg)
The growth rates for some technologies are quite large.
![Page 16: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/16.jpg)
One of the main lessons is that much of the growth in renewable energy takes place in the developing world.
![Page 17: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/17.jpg)

In the SRREN, a small set of scenarios were used to for a more detailed exploration.
![Page 19: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/19.jpg)

Chapter 10 used these specific scenarios to construct cost curves.
![Page 22: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/22.jpg)
Chapter 10 also produced mitigation by technology for these scenarios.
![Page 23: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/23.jpg)

These sorts of ranges were passed to the chapter with the goal that they would try to explain what might need to happen to get to the higher deployment levels.

Where are we headed with AR5?
! Lots and lots and lots and lots of scenarios ! AMPERE, EMF 24, RoSE, LINKS, AME
! Imagine how much more illuminating this graph will be with ten times more scenarios!!
![Page 27: Use of Scenarios in the Special Report on Renewable Energy ... · the IPCC Fifth Assessment Report Leon Clarke May 25, 2011 Global Technology Strategy Program Technical Workshop Joint](https://reader036.vdocuments.mx/reader036/viewer/2022081616/5fffd4bf4a01a11c9f0ee880/html5/thumbnails/27.jpg)
Where are we headed with AR5?
! But there are some particularly important new dimensions of coordination of scenarios: ! Technology, particularly with limits on the deployment of particular
technologies, for example, nuclear energy and CCS. ! Policy, particlularly idealized policy scenarios, for example the
EMF 22 and EMF 24 scenarios. ! Linkage to RCPs. ! Some scenarios with coordinated socioeconomics.
! Remaining to be worked out ! How will scenarios be used within WGIII? ! How will the RCPs be used to link across working groups?
