2. World Energy Use by Fuel

3. Goals of this Project • BPM • Final document for Stantec • Checklist and Comparison Chart • Renewable energy options • Most commonly used options • Option Analysis • Location and Efficiency • Cost and Feasibility • Downsides and Environmental Impacts

4. Stantec’s Challenge • Limited number of renewable energy “experts” • Lack of standardized document or “textbook” • Ample supply of information available • Stantec would benefit from a BPM for entry level engineers

5. Decision Tree

6. Renewable Energy Options

7. Research • Searched through sources to find: • Best Location • Cost Range • Efficiency • Downsides/Environmental Impacts • Case Studies

10. Checklist Concentrated Solar Power ___CSP power plants need a large area’s of land, up to hundreds or thousands of acres. ___ Cost of CSP plants range from $2M to $5M per MW ___ Cost of electricity from CSP plants is around $0.12/kWh but is expected to drop in the near future due to increased research, manufacturing, and development. ___ The best locations for CSP plants are often deserts which are unusable otherwise ___ Current CSP technologies can convert 20-40% of sunlight ___ When thermal storage units are incorporated into a CSP plant it can increase its capacity factor and continue to produce energy in the dark ___ CSP plants emit no greenhouse gases during operation Offshore Wind ___ Current technology only allows offshore turbines in water up to 30 Meters deep ___ Minimum wind speeds of 8 mph are required for a turbine to generate electricity ___ The coast of the Northeastern U.S. and the Cost of the Pacific Northwest from Oregon to Alaska are good locations to site offshore wind farms ___ Farms cost around $2.4M per MW of capacity and electricity costs $.095/kWh ___ Wind turbine capacity factors are around 30% however strong and more consistent offshore winds could increase that number. ___ Farms can be properly sited to avoid fishing grounds and shipping lanes ___ There is often public concern for the marine environment and visual aesthetics

11. BPM • “Textbook” format • Detailed description of information provided in checklist and chart • Information is cited • Various case studies for each of the technologies

12. Design Example

13. Conclusion • Each option is applicable in specific locations • Biodiesel and geothermal heat pumps can be applicable almost anywhere • Hybrid systems
