Smart Grid


Description


Communication between grid and appliances


Peak load shaving and elimination of vampire loads



CO
2
savings from distribution and transmission
losses is ~ 40 million tons


CO
2
savings from vampire load elimination is
760 million tons


Total is 800 million tons


1 billion tons will be reached by V2G technology
made possible by the smart grid

Increasing Vehicle Efficiency


Facts


Passenger Vehicles on Road= 244mil


New Vehicles Purchased / Year = 16mil


Average MPG of New Car = 21mpg


Average Annual Miles Driven = 11,360mi


CO2 / Gallon of Gas = 18lbs



Increasing Vehicle Efficiency


Assumptions


Can only affect new vehicles, not existing fleet


Can achieve fuel economy of 40mpg on
average


Emissions reductions from previous years
continue to factor in until the vehicles from
that year have been retired


Average retirement age is 15 years

Billion Tons Reduced
Coal to Nuclear Transition


The replacement of 1% of current coal fired
power with nuclear power will reduce CO2
emissions by approximately 1 billion tons
over 47 yrs.


This is equivalent to the replacement of
approximately 890 million MWh of coal fired
production with nuclear power.



Building infrastructure


2.5 billion tons of CO2 from residential
sector/year


6 billion tons of CO2 from industrial


3.3 billion tons of CO2 from commercial
sector/year


Saving 1 Billion Tons of CO2 via


20% of residential & commercial


Industrial is difficult to reduce
