Wedge
1 Wedge 1 gigaton carbon emissions reduction
per year
6
Model

• Displace
• 1 wedge of carbon
• varying amounts of world electricity (0 to 24)
• Light-duty transport fuel
• Something

USA
13
China
Displace 20 Electricity
303,000 Turbines Needed
1.98 Country Land Area
Would also provide enough H2 to displace 332 of
current light-duty fuel use
14
France
Replace all fossil fuel power generation
25,000 Windmills
1.16 Land Area
Would also provide enough H2 to displace 32.9 of
current light-duty fuel use
15
Sweden
Replace all fossil fuel power generation
Replace 50 power generation
5,920 Windmills
3,880 Windmills
0.44 Land Area
0.28 Land Area
Would also provide enough H2 to displace 37 of
current light-duty fuel use
Would also provide enough H2 to displace 24.3 of
current light-duty fuel use
16
Remote Island
Create Emissions-Free Power and Transportation
4 Windmills
0.83 Land Area
Would also provide enough H2 to displace 6,650
of current light-duty fuel use

Summary

• Climate change is real
• Hybrid Wind-Hydrogen systems can work to mitigate
  effects
• Deals with intermittency
• Sds
• Model O(Pacala Socolow)
• 1.7 million turbines
• 500,000 km2
