What we’ll cover:

• What do these terms mean?• How much energy do I use?• What does energy cost?• How much energy is produced?• What can I do?

3

What do these terms mean?

• Volts: – A measure of the electrical power “pressure”

employed by an appliance.• Voltage is to electricity as Pressure is to water.

4

What do these terms mean? (2)

• Ampere: – The rate of flow of electricity• The proportionate amount of electrons flowing through

a conductor past a given point in one second.

5

What do these terms mean? (3)

• Watts: – The measure of the rate of electrical use at any

moment.• Watts = Volts x Amps• Think of it as the speed on a speedometer!

6

What do these terms mean? (4)

• Watt-Hours and Kilowatt-Hours– Total energy used over time.• Watt Hours = Watts x Hours • kWH = Watts x Hours measured in Thousands• This is what you pay for on your Electric Bills!

How much Energy do I use?

• Cooling– Small window unit AC• 900 Watts

– Big window unit AC• 1400 Watts

– Central Air Conditioning• 3500 Watts

– Ceiling fan 42”• 24 Watts

9

How much Energy do I use?

• Heating:– Electric Space Heater (low setting)• 600 Watts

– Electric Space Heater (high setting)• 1440 Watts

– Electric Furnace / Central Heating (CA)• 7900 Watts

– Central Heating (Cold Areas)• 26,000 Watts

10

How much energy do I use?• Appliances

– Water Heater• 3800 Watts

– Dishwasher• 3600 Watts

– Electric Oven at 350oF• 2000 Watts

– Refrigerator (Compressing / Average)• 500 Watts / 100 Watts

– Microwave• 1440 Watts

– Coffee Maker• 900 Watts

– Clock radio• 4 Watts

11

How much energy do I use?

• Lighting– Incandescent Light bulb• 60 Watts

– CFL Light Bulb• 18 Watts (looks like 60 watts)

– LED night light• .5 Watts

12

How much energy do I use?• Electronics

– Desktop computer and 17” Monitor• 300 Watts

– 50” Plasma TV• 340 Watts

– 50” LCD TV• 260 Watts

– PS3• 195 Watts

– Xbox 360• 185 Watts

– Nintendo Wii• 20 Watts

13

How much energy do I use?

One – AA Battery Contains a total of 3 kWH.

To put this in perspective,it would take 1000 batteries

to do one load of laundry.

Lets put this in perspective!

Leaving the heater on all day at 82oF is~200 kWH a day (during winter months)

To put this in perspective, Turning on the heater only while your home would save you enough money

in 1yr to buy a Used Car.

What does energy cost?

• U.S Residential National Average– 12¢ per kilowatt hour

• California Average– 15.22¢ per kWH

• In Sacramento (SMUD):– Nov – Apr

• 9.5 ¢ per kWH• 17.55 ¢ per kWH (after 1120 kWH used)

– May – Oct• 10.2 ¢ per kWH• 18.2 ¢ per kWH (after 700 kWH used)

Prices go up if you use more energyPrices go up in the summer time

16

What does energy cost?

• Sacramento’s Optional Time-of-use-Rates

- Nov – Apr- 10.5 ¢ per kWH (on peak)- 9.75 ¢ per kWH (off-peak)

- May-Oct- 23.5 ¢ per kWH (on-peak)- 10.9 ¢ per kWH (off-peak)

- Peak Hours of Energy-Use: 4pm – 8pm

19

How much energy is produced?

• In the US today, 12% of energy comes from renewable sources. Wind, Water, and Sun.

• If traditional power plants were converted to renewable production sites, 93 % of our energy could come from renewable sources.

20

How much energy is produced?

Solar Energy is more viable in some areas than in others.It serves as a great Residential energy source in California.

In most of CA:1 Square Meter of Solar Panels will produce 6kWH each day.

That’s $275 per year!(Plus tax rebates!)
