The Energy Future We Could Create
The Sun is Amazing Workshop
June, 2012
What is the goal?
•
•
•
•
Environmental stability?
Enough to meet needs?
Fairness in life chances?
Less about stuff, more about community, family?
Five Elements:
1. Efficiency: low power, high performance
appliances
2. Low Power high efficiency buildings
3. Green Energy
4. Smart Use: Matching consumption with power
production (e.g. electric cars with night wind)
5. Sparing use of fossil fuels at transitional fuel and…
Innovation
Starting point:
The Art of the Possible
Let’s consider examples of what we
know works
Example: Arthur Rosenfeld
• The Principle: Conserving
Energy is simpler and cheaper
than building more power
plants.
• Efficiency measures save
Californians $30B/ year.
• Air pollution Avoided: 100
million cars equivalent
“Rosenfeld Effect”
20
power
plants
not built
Alliance to Save Energy
• Energy Efficiency Movement saves Americans $700
Billion per year in energy bills [ck]
Low hanging Fruit:
Cool Roofs: reflective colors
• Chicago to Sydney latitudes equivalent to taking ½
the worlds cars off the road; a 20 year reprieve on
global warming

Art Rosenfeld.
Conservation and Efficiency:
McKinsey Report (2009)
$520 B investment-1.2 Trillion saving (100% ROI)
23% reduction in U.S. Energy Consumption
McKinsey analysis
Political Will
When government sets standards and
means it, engineers figure out how to
do it
California Leads
Renewable Portfolio Standard:
33% by 2020
ISO and Utilities have to figure it out
2008: Governor Schwarzenegger issues Executive Order S-14-08
requiring 33% renewables by 2020.
2011: Senate Bill X1-2, signed by Gov. Edmund G. Brown, Jr., codifies
33% by 2020 RPS.
ISO demonstrates effect of political mandates:
Mandatechallenges solutions.
Not bad: 1% or less margin
When California leads….
When California forces
manufacturers to build more
efficient appliance….
e.g. refrigerator, it changes nation
because manufacturers don’t want to
build two different products
And US Solar market grew 109%
last year (2011)
And industry incentivized to
improve Technology
E.G. market for battery technology
Prototypes with 10x greater energy
density
Global element of improving
energy future:
Help Developing World Leap Frog
Fossil Fuel Step
E.g. wireless communications and electricity
Renewable Resource is Huge
Solar Resource
10,000 x more energy then humans use
(Art Sussman)
Wind Power Resource:
16 X Current Consumption
Proceedings of the National Academy of Sciences of the United States.
(2009)
Wind Resource in the United States
(as percentage of in-state generation)
Dakotas and Nebraska are the “Saudi Arabia” of Wind Power
People need jobs: let’s get it done
