What Google Means to Energy
• Google has invested $780 million in renewable energy generation and tech development
• Google boasts themselves as being a neutral carbon company, offsetting as much CO2 as they produce
• The G-mail system is said to be 80% more efficient than company in-house e-mail service

Outline- Google’s overall Carbon footprint calculation if all
of their energy was from power plants
- Google’s wind and solar offsets
- The things we don’t think about (What would the
world be like without Google)
- What is the carbon footprint of this project???

Assumptions - All the power is coming from coal power plant.
- Account for all of Google searchers, Gmail and
YouTube usage and all other Google applications.
- Average trip to the library is 1.5 miles each way.
- 70% of bituminous coal is Carbon.
- Everyone used Google to complete their project

Google CO2 Output• Google reports using 260 MW of energy • Efficiency of average coal power plant is 30%• chemical energy of power plant• Bituminous coal produces 2.32E10 J/ton coal

Google’s Wind Offset
• 30% of Google’s energy is predicted to be wind in
2011.
• )( CO2
• MW

Google’s Solar Offset• SolarCity project by Google is installing 10,000
solar systems predicted to produce 7 MWh per year each
• Per system
• Total

What if We Didn’t Have Google?
• .
• Assume only 25% of people would drive to the library if we didn’t have Google.
• (0.85)CO2

How Much Do Searches Save?
• Searches make up 12.5 MW of Google’s energy usage.
• 1.32E5 - 2.667E7= -2.64E7 CO2
• Google saves 26.4 Million metric tons of CO2 per year!
![Page 10: Grant Klinger Abdulrahman Maddi Bill Miller Taylor Miller.](https://reader035.fdocuments.us/reader035/viewer/2022062314/56649dbe5503460f94ab2655/html5/thumbnails/10.jpg)
Google CO2 Emissions of EGEE
012 • 40 searches * 15 groups = 600 searches
• This project is producing almost half a pound of CO2 just from Google searches!!!

Differences• Calculated – Wind offset – Solar offset = Total • NewYork times report 1.5
• Compare to 26.4 Million metric tons per year saved
by not going to the library

Conclusion- Online activity is increasing significantly each
year.
- Google is pushing toward more renewable energy
sources.
- If Google didn’t pursue more efficient equipment
and methods CO2 footprint would DOUBLE.
- Google also contributes in the development of
renewable energy and technology.
- Yahoo doesn’t release their energy information.
