The Long Now Foundation : January 02009 Climate Change Recalculated Saul Griffith. Makanipower.com Wattzon.com

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

would you prefer your taxes spent on schools or roads?

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

you have heard about... climate change

you have heard about... carbon footprint

you have heard about... energy independence

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

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

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

Two stories : one global, one personal.


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

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

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

Running this Apple laptop takes 40 Watts.

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

"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 )

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.
