Wandering in Romm’s World

While wandering aimlessly, I stumbled upon a post that struck me.  Since I have never been invited to or have read any books on the matter, I was curious on what this *wedge* might be.

Much like the many *games* that are played by the CAGW establishment, here is yet another:

Stabilization Wedge Game

In this “game”, it appears that you have pieces of “pie” to place on the “problem” to achieve a solution or “covering” of the problem.  Let us say that there is a CAGW problem, you have 8 pieces of a 45 degree angle wedge of pie to cover over the problem (mitigate, avoid, piss-on, piss-off, who knows…).  These are known as the “8-Strategies”.  Okay, check.

Of these “8-Strategies”, there are the following options:

1. Renewables & Biostorage Wedges (Green; of course)

2. Efficiency & Conservation Wedges (Yellow)

3. Fossil-Fuel Based Wedges (Blue)

4. Nuclear Electricity Wedges (Red; of course)

5-8 … No prefabricated wedges… hmmm…

Keeping emissions flat will require cutting projected carbon output by about 8 billion tons per year by 2055

is the goal.  Let us try to unravel this.

To make the problem more tractable, we divided the stabilization triangle into eight “wedges.” (Figure 4) A wedge represents a carbon-cutting strategy that has the potential to grow from zero today to avoiding 1 billion tons of carbon emissions per year by 2055, or one-eighth of the stabilization triangle. The wedges can represent ways of either making energy with no or reduced carbon emissions (like nuclear or wind-produced electricity), or storing carbon dioxide to prevent it from building up as rapidly in the atmosphere (either through underground storage or biostorage).

Okay, I shall not bore you with the silly linear slope of carbon production of fig. 4.  If you are inclined to read it, feel free.

Back to the post.  So, after the game pieces are cut, the *wedges* represent a billion tons a year that can be placed over the problem.

1. Renewables and Biostorage :

  • Wind-generated electricity
  • Solar electricity
  • Wind-generated hydrogen fuel
  • Biofuels Forest storage Soil storage

2. Efficiency & Conservation:

  • Increased transport efficiency
  • Reducing miles traveled
  • Increased building efficiency
  • Increased efficiency of electricity production

3. Fossil-Fuel-Based Strategies:

  • Fuel switching (coal to gas)
  • Fossil-based electricity with carbon capture & storage (CCS)
  • Coal synfuels with CCS Fossil-based hydrogen fuel with CCS

4. Nuclear Energy

  • Nuclear electricity

Wow.  What an interesting teaching tool.  Now, what I am understanding is that Joe Romm thinks that the Nuke wedge is not 1.00 but 1.77, which is a significant contribution from the “warmer” side of the CAGW debate.  I would have to modify the Renewables and Efficiency/Conservations to reflect a 77% reduction/effectiveness and this game might take off 😉
