5. 2007: Google.org’s RE<C vision
2016: Wind and Solar now cheaper than Coal
Bloomberg, Wind and Solar Are Crushing Fossil Fuels, Apr 2016.
Coal power is no longer
“business-as-usual”.
For many years,
renewables have been
“business-as-usual”.
6. 2007: Google.org’s RE<C vision
2016: Wind and Solar now cheaper than Coal
2026: Wind and Solar will be much cheaper than Coal
excerpted from Lazard, Levelized Cost of Energy
Analysis Version 10.0, Dec 2016.
Another decade of
experience curve effects
will magnify wind and
solar’s cost advantages.

Second Thesis
11. IPCC Scenario Compression - Preamble
● IPCC contributors are experts in their fields
● They come from all parts of the world and the political / cultural spectrum
● Their work is fairly-often and often-unfairly politicized and demonized
● IPCC models represent our best efforts to understand climate change
● IPCC models are based on peer-reviewed science
● We are all subject to human frailties (bias, self-interest, etc.)
● Peer-review is the most effective way of freeing the pursuit of truth from the
distortions of those frailties
● Of course, no human system is perfect, or should be expected to be
12. IPCC Scenario Compression - Preamble
Peer-review takes time -- scientific inquiry is inherently conservative --
so IPCC models are always somewhat out-of-date.
13. IPCC Scenario Compression - Preamble
Peer-review takes time -- scientific inquiry is inherently conservative --
so IPCC models are always somewhat out-of-date.
IPCC models do not factor in recent trends such as:
● Arctic sea ice death spiral

16. IPCC Scenario Compression
Here are IPCC’s Representative Concentration Pathway (RCP) models
IPCC Climate Change 2014 Synthesis Report, Figure 3.2a
“RCP8.5 is representative of
the high range of non-climate
policy scenarios”.

“RCP8.5 is representative of

policy scenarios”.
Good news: even
without climate policy,
RE<C in 2016,
RE<<C in 2026,
RE<<<C by 2100.
Coal use should be
lower than RCP8.5
projections.
18. IPCC Scenario Compression
All RCP’s assume higher coal use
(with or without CCS) in 2100 than 2000.
This seems unlikely. RE<C today.
Besides, CCS will only add costs to coal.
RE<<(C+CCS) might already be true.

19. All RCP’s assume higher coal use
(with or without CCS) in 2100 than 2000.
This seems unlikely. RE<C today.
Coal use may already be falling!

IPCC assumptions were valid at the time.
Renewables were more expensive than coal,
and experience curves for wind and solar
weren’t widely known.
RE<C changes all of this.
From https://skepticalscience.com/rcp.php?t=3
21. Given RE<C in 2016
and RE<<C in 2026
(and RE<<<C in 2100)
the author believes that by 2026, the IPCC
will focus more on lower-coal (and therefore
lower-emission) RCPs.
RCP8.5 probably first to be de-emphasized.
Could those researchers redirect efforts
towards a zero-coal RCP?

22. IPCC Scenario Compression
If RE<C can prevent highest-emissions RCP scenario from coming true...

2016: given RE<C, this won’t happen
23. IPCC Scenario Compression
And RE<<C can reduce the likelihood of the next-highest RCP scenario...
IPCC Climate Change 2014 Synthesis Report, Figure 3.2a
2016: given RE<C, this won’t happen
2026: if RE<<C, maybe this won’t
happen?
24. IPCC Scenario Compression
...over time we may see a “compression” of IPCC scenarios.

This would be encouraging - we could avoid worst-case temperature scenarios!

It could also cast the climate challenge in opportunity, not avoidance, terms.

That’s still far too high!
Much work still to be done!
But, what a paradigm shift!
27. IPCC Scenario Compression
Even if IPCC Scenario Compression occurs, serious concerns remain.
We’re still on worse-than-projected trends for:
● polar ice loss
● sea level rise (Greenland, Antarctic melt not in models as of 2012)
● methane emissions
● and no doubt other factors the author is unaware of,
but which are known in the climate science community
28. Probable Responses to IPCC Scenario
Compression
Pollution doves will likely call for redoubled inaction and investments elsewhere.
“We’ve dodged a Permian-scale extinction, why spend billions to prevent
a Cretaceous-scale extinction?”

Compression

“We’ve dodged a Permian-scale extinction, why spend billions to prevent
a Cretaceous-scale extinction?”
Climate hawks will likely call for redoubled action and investment.
“Why unlock trillions in climate wealth over a hundred years,
when we can unlock it in twenty, as responsible stewards?”
30. Author’s expectations
I expect this presentation will:
● be greeted warily among progressives and climate activists
“Is he trying to sabotage future policy action?” (no, quite the opposite)
● be embraced by conservatives and climate inactivists
“Does he hate climate science or Al Gore, too?” (no, quite the opposite)
● be contentious
All opinions and any errors herein, are mine
31. Author’s hopes
I hope this presentation and its theses can:
● persuasively argue that RE<<C and IPCC Scenario Compression will be the
most important technological development in the next ten years;
● frame our clean technology successes;
● inspire positive action on cleantech and climate;
● assuage fears that we’re doomed to have the worst come to pass;
● provide a generational narrative (this is our ‘moon landing’);
● affirm the power of ethical ideals and entrepreneurial zeal;
● and if possible, win the competition ( just being honest )
