Webcast of energy literacy talk for O'Reilly media.

1. Two stories : one global, one personal.

2. Energy is measured in Joules (J)
Lifting an apple from
the ground to the
table. ~ 1 Joule

3. Power is measured in Watts (W).
1 Watt = 1 Joule / second
Lifting one apple from
the ground to the table
each second. ~ 1 Watt.

4. 40 apples per second
from the ground to the
table = 40 Watts.

5. Running this Apple laptop takes 40 Watts.

6. Power
100 W = You, sitting there, reading.
1000 W 1kW = Domestic kettle
1 kilowatt (kW) = 1000 W
1000000 W 1MW = Diesel locomotive / wind turbine.
1 megawatt (MW) = 1000 kW
1000000000 W 1GW = Hoover dam
1 gigawatt (GW) = 1000 MW
1000000000000 W 1TW = World power consumption, 1890
1 terawatt (TW) = 1000 GW

7. HOW MUCH POWER
DO I USE?

8. Why watts ?
Allows you to compare activities on different timescales.
Allows you to consider non-carbon effects of using so much power.
If you do something yearly (like fly 105,000 miles), it contributes:
168,207 kilometers 1 year 1.40 megajoules Joules
1 year
�
31,536,000 seconds
�
1 kilometer
� 7,462
second
= 7,462 Watts
If you do something monthly (like your electricity bill), it contributes:
122 kilowatt ·hours 1 month 3.6 megajoules Joules
1 month
�
2,952,000 seconds
�
1 kilowatt · hour
� 170
second
= 170 Watts
If you do something daily (like drink 1 Energy drink), it contributes:
1 energy drink 1 day 7.84 megajoules Joules
1 day
�
86,400 seconds
�
1 bottle
� 90
second = 90 Watts
Yearly things + Monthly things + Daily things = your lifestyle in watts.

9. "Watts per always" - your life in light bulbs.
100W
A 12,000 Watt lifestyle is 120 x 100
watt light bulbs burning permanently.
( Or 920 Compact Fluorescents )
