1. Energy Efficiency and Conservation

2. What’s the difference between Energy Efficiency and Energy Conservation?

3. Energy Conservation: reducing energy use to be less wasteful Energy Efficiency= useful energy output x 100 % total energy

4. Efficiency Ex: MPG Energy Efficiency= useful energy output
total energy
= # of miles out
# of gallons in
= Miles PER gallon

5. CFL vs. IB

6. Cogeneration: the process of reusing excess utility plant heat for home heating.
Cogeneration-> efficiency or conservation?

7. Pair Share
In 2011, Transportation accounted for 28% of the total Energy Consumption in the U.S. and accounted for 27% of total U.S. Greenhouse Gas Emissions. As the largest end-user of energy in the U.S., the transit sector is a huge target for both conservation and efficiency strategies. What is one conservation strategy for transit? What is one efficiency strategy for transit?

8. H.O.V.

9. Electric Vehicles Pros: Cons: -Quiet
-Transfer pollution from car to power plants
-Reduce C02 emissions
-Less money at the pump!
- Limited charging stations
-Can get electricity from different energy sources
Up front costs
Limited range (can’t drive as far)
*note how BIG market are young people who don’t have houses, so can’t charge their vehicles.

11. CAFE Standards U.S. Standards Goals: Benefits: Challenges:
Also include incentives to advance specific technologies including EV, plug in hybrids and fuel cell vehicles
Goals:
Automakers double fuel economy (mpg) to 54.5 mpg by 2025.
Benefits:
Reduce oil consumption by 12 billion barrels*
Save consumers $ on gas
New jobs
Challenges:
Added cost raises price of new cars (by 3,000$)
Limited choice
*note one barrel is 42 gallons (bring in empty gallon)- embedded math question- how many gallons of oil is that? The main part of the bay is 400 miles squared and about .003 miles deep so its 1.2 miles cubed. 1 mile cubbed holds 10 to the 12 gallons of water, so there are roughly 1.2 times gallons of water in SF bay. 12 billion barrels is .5 x10^12. So that means (VERY roughly) half of the ‘main’ part of sf bay

12. ZEV Action Plan California plan Goals: Benefits: Challenges:
to put 1.5 million ZEVs on CA roads by 2025,
meet long term emission reduction targets by 2050,
build infrastructure in cities
Benefits:
Save Californian’s $ in fuel
Meet Fed air quality standards
Reduce gas imports
Challenges:
New infrastructure
Consumer awareness
Initial Costs
Limited ZEV model choice
