80% below 1990 means:Reduce US Carbon pp from 5.5 tons/yr to < 1 ton/yr
ENORMOUS EFFORT: Capture all carbon from all coal plants (to date 0). Triple coal and gas plants, also with all carbon captured. 2/3 of all cars/trucks all-electric, rest adv. biofuels. In units of 1000 MW (a typical nuke) by 2050 we need:
– 1200 wind (last year 8)– 1400 solar (last year .3)– 500 nuclear (last 20 years 0)

3% savings per yearAcquiring all available cost-effective electric energy efficiencyas set forth in the Green Communities Act (GCA) would likely require an annual energy savings level of about 2.5% per year, or about three times the energy savings levels in past years.
How will we Enable Energy Efficiency?
US Buildings consume 71% of all electricity, 55% of all natural gas
30% efficiency achievable by 2030 with 3 Deployment options:
1. Public funding models, incl. utilities: carrots2. Codes and Standards: sticks3. Data and intelligence-driven : information
Transforming the nation’s consumers: good energy decisions (ie lower discount rates) change everything.
Smart Grid/AMI Granular Energy Data: - energy diagnostics, feedback, control
Behavior impacts of smart grid-based information options may be as high as 30%:
Daily End-use Carbon Footprint? Collective Action?
Fault-detection Thematic Control – make me green Control Precision Adaptive Control Strategies
Only at the very beginning of adding inference/diagnostics to the Energy Internet

Consumer-responsive Architecture = Providing consumers with energy diagnostics, feedback, control
refers to systems for optimizing consumers’ end-use needs (especially air conditioning, heat, hot water)
based on weather, schedules, and time differentiated costs.
Time-differentiated rates are more fair, and some would argue inevitable.
Customer Responsive Systems work 24/7,
providing efficiency as well as peak demand response.
Consumer-Controlled, Public Network Architecture:

Consumer-side
Key Hypothesis: Utilities create the enabling conditions for market-based systems
To accomplish this, utilities, regulators should focus on:– consumer-centric architectures for appliance control,– Open and public architecture for AMI communication, – Encouraging a broad ecosystem of content providers,
including utilities.
2013 – How will efficiency look – when the politics change? Smart meters and dynamic pricing – will we move forward? The nation’s consumers – will we innovate, educate, and support
good energy decisions? (ie lower discount rates)
We can do this – but can we do it in time?
