WattzOn is a new, free digital application that allows anyone to more broadly understand their real energy footprint. The rich online audit calculates personal energy consumption from flying, driving, powering a home, eating, shopping, working and even one's share of the energy necessary to make our society function. WattzOn helps users understand their personal impact on the environment and how they rate compared to others WattzOn users, as well as global averages.
These slides were delivered at the 2008 Web 2.0 Summit. Check out WattzOn at http://www.wattzon.com. Follow our blog, What's On? at http://blog.wattzon.com, or at twitter as @wattzon.

A social network around the notion of energy
use and conservation.
A wiki methodology for assembling a profoundly
complex dataset.
Share. Compare. Learn. Change.
11. What is my relationship to climate and energy?
13. Energy & power basics
Energy is measured in Joules (J)
Energy is a measurable amount. A quantity.
Lifting an apple from
the ground to the
table. ~ 1 Joule
14. Energy & power basics
Power is measured in Watts (W).
1 Watt = 1 Joule / second. 40 apples per second from the
Power is the rate of using ground to the table = 40 Watts.
energy.
15. Energy & power basics
Running this Apple laptop
takes 40 Watts.
16. Using units of power allows you to compare things that happen on
markedly different time scales. yearly + monthly + daily + ...
Power, in Watts, is like an average.
The average amount of energy, in Joules, you use each second.
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

= 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 Watts
If you do something daily (like drink 1 Energy drink), it contributes:
1 energy drink 1 day 7.84 megajoules Joules

1 bottle

Think of your life in light bulbs....
A 12,000 Watt lifestyle is 120 x 100
watt light bulbs burning permanently.
