Put the individual in climate context.

HOW MUCH POWERDO I USE?

Page 4: Saul Griffith: An Engineer's Approach To Climate. Working Backwards From Where We Want To Be

Energy is measured in Joules (J)

Lifting an apple from the ground to the table. ~ 1 Joule

Page 5: Saul Griffith: An Engineer's Approach To Climate. Working Backwards From Where We Want To Be

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

Power is measured in Watts (W). 1 Watt = 1 Joule / second

Page 6: Saul Griffith: An Engineer's Approach To Climate. Working Backwards From Where We Want To Be

Running this Apple laptop takes 40 Watts.

Page 7: Saul Griffith: An Engineer's Approach To Climate. Working Backwards From Where We Want To Be

Power, in Watts, is like an average.The average amount of energy, in Joules, you use each second.

So now you can add all these things.Yearly things + Monthly things + Daily things = your lifestyle in watts.

If you do something yearly (like fly 105,000 miles), it contributes:

If you do something monthly (like your electricity bill), it contributes:

If you do something daily (like drink 1 Energy drink), it contributes:

Think of your life in light bulbs....

A 12,000 Watt lifestyle is 120 x 100 watt light bulbs burning permanently.

The year of 'peak waste'

Page 36: Saul Griffith: An Engineer's Approach To Climate. Working Backwards From Where We Want To Be

If the average American were to leave home each morning with a backpack full of the fuel they need-ed for their day:

Oil = 31 kg, 67 lb.Coal = 29 kg, 63 lb.Gas = 6 kg, 12 lb.

11 400 Watts.

+ 0.2 x TWy + 0.15 x TWy + 0.11 x TWy

There's a known and reasonably predictable amount of carbon left to burn:

1 TWy = 1 Terawatt Year = 3.16 x 1019 Joules.

CO2 ppm = CO2 ppm

1 Joule of fossil energy used produces 4.9x10-21 ppm increase.

How many ppm to replace every gasoline car in the world (1bN) with a 1000kg electric vehicle? = 0.49 ppm

How many ppm for 250 million new green homes? = 8.9 ppm

How many ppm for installing :

5TW solar = 6.1 ppm3TW wind = 0.55 ppm2TW geothermal = 0.49 ppm

So there is + 19 ppm right there. Scary.

Might be good to ask questions of form:

How many ppm for 6 bN new laptops? = 0.05 ppm6 bN cellphones? = 0.03 ppm6 bN 100 Watt lightbulbs burning for 1 year? = 0.2ppm

And we will too.

The world demands more and more energy. Where will it come from? We at Chevron

are working to provide more of it, both responsibly and effi ciently. And we’re developing

alternatives. But it’s just as important for all of us to do more with less.

We’re doing it ourselves — and enabling others. Our Chevron Energy Solutions

team is dedicated to helping others use less energy. In Colorado, we’ve

worked with the state to improve 20 state buildings. The extensive makeover

is expected to save more than $20 million over the next two decades.

It’s just one of the hundreds of projects that will help businesses and

government organizations reduce their energy costs by over $1 billion.

Join us in one of the most important efforts of our time — using less.

Will you?
