Sustainable Energy Setting Goals and Attaining Them The
Sustainable Energy Setting Goals and Attaining Them
The Target Apply Newton’s Laws And Build a Device Declare a Goal and Commit to it!
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
Solar Energy
Oceanic Mechanical Energy
Oceanic Thermal Energy
Geothermal Potential
400 Million Gallons Per Day
Transmission Lines Use Hydrogen as a Proxy for Transmission
Evaluate Options u Capital Cost ($ per Megawatt) u Levelized Costs (lifetime of facility) u Amount of Land Used u Amount of Material Used u Greenhouse Gas Emission Reductions u Scalability of Technology
Achieve Realistic Goals 30% Annual US Electrical Demand met by Wind Power by 2030 (100, 000 Turbine Project) u 50% of Daytime American Southwest Electrical Demand with CSP/PV rooftop arrays by 2025 u 20% of extant cropland for Switch grass @50 MPG = ½ of our fuel consumption by 2020 u Worldwide conversion to OTEC +Hydrogen by 2075 u
Conclusion u. A NASA like effort is needed to reach these goals u Without such an effort, Alternative Energy will remain a niche Market u We can’t suddenly switch from Fossils to Renewables 30 year transition time is needed u Conservation is an important form of alternative energy production
