Sustainable Energy

• Setting Goals and Attaining Them

2
The Target
Apply Newtons Laws And Build a Device
Declare a Goal and Commit to it!
3
Key Message

• Choices now exist for both large scale and small
  scale implementation
• Barriers are
• Initial/Capital Costs
• Lack of Leadership
• Implicit/Explicit belief that fossil energy
  remains abundant
• NIMBY Land Use Issues

Wind Energy
5
Solar Energy
6
Oceanic Mechanical Energy
7
Oceanic Thermal Energy
8
Geothermal Potential
9
400 Million Gallons Per Day
10
Transmission Lines
Use Hydrogen as a Proxy for Transmission
11
Evaluate Options

• Capital Cost ( per Megawatt)
• Levelized Costs (lifetime of facility)
• Amount of Land Used
• Amount of Material Used
• Greenhouse Gas Emission Reductions
• Scalability of Technology

12
Achieve Realistic Goals

• 30 Annual US Electrical Demand met by Wind Power
  by 2030 (100,000 Turbine Project)
• 50 of Daytime American Southwest Electrical
  Demand with CSP/PV rooftop arrays by 2025
• 20 of extant cropland for Switch grass _at_50MPG
  ½ of our fuel consumption by 2020
• Worldwide conversion to OTEC Hydrogen by 2075

Conclusion

• A NASA like effort is needed to reach these goals
• Without such an effort, Alternative Energy will
  remain a niche Market
• We cant suddenly switch from Fossils to
  Renewables ? 30 year transition time is needed
• Conservation is an important form of alternative
  energy production
