3. Would you prefer
a glass of wine
every evening, or
an annual business
trip?

4. would you prefer
your taxes spent
on schools or
roads?

5. would you prefer a
hot shower every
day or eating
meat?

6. you have heard about...
climate change

7. you have heard about...
carbon footprint

8. you have heard about...
energy
independence

9. let us have a look at these things as though:
we are reconciling the
short term us...
with the 10000 year
future of us...

10. and hopefully we'll answer two questions...
how do your personal
actions effect climate?
can there be a global
solution for climate
change?

11. a big pile of numbers to show you that...
climate change and
energy issues are
aesthetic issues.
what is a quality life?

12. Two stories : one global, one personal.

13. HOW MUCH POWER
DO I USE?

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

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

16. 40 apples per second
from the ground to the
table = 40 Watts.

17. Running this Apple laptop takes 40 Watts.

18. 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

19. "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 )

20. 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.
