3 Emerging RE Technologies Solar-thermal power Ocean-thermal power Tidal power Photo Credit: Gretz, Warren DOE/NREL Parabolic-Trough Solar Power Plant Ocean current power Wave power etc. Central Receiver Solar Power Plant Photo Credit: Sandia National Laboratories DOE/NREL Project Viability Depends on Several Factors RE resource at project site (e.g. solar radiation) Fort Smith Solarwall Equipment performance (e.g. solar absorptivity) Initial project costs (e.g. solar collectors) Base case credits (e.g. conventional cladding) Annual & periodic costs (e.g. vandalism) (Solarwall Example)

4 Project Viability Depends on Several Factors - cont. Base case system energy cost (e.g. retail price of heating oil) Financing (e.g. debt ratio & length, interest rate) Taxes on equipment & income (or savings) Environmental characteristics of energy displaced (e.g. oil, natural gas, grid electricity) Environmental credits and/or subsidies (e.g. GHG credits, deployment incentives Ouch! ) Decision-maker s definition of cost-effective (e.g. payback period, ROI, NPV, RE production costs) Market Acceptance vs. Simple Payback Market Acceptance Curves 100 Market Acceptance vs. Simple Payback Residential Commercial/Industrial Other 80 Market Acceptance (%) Simple Payback (yr) Market Acceptance vs. Simple Payback Data Table Market Payback yr Residential % Commercial/Industrial % Government % Version 2001 Minister of Natural Resources Canada NRCan/CEDRL

7 Under Development: RETScreen Version 3.0 External Funding Partners: Prototype Carbon Fund (PCF) at The World Bank The United Nations Environment Programme (UNEP) New Developments & Main Upgrades: Combined Heat & Power (CHP) Model Metric/imperial unit switch Sensitivity and Risk Analysis worksheet Updated GHG model to account for emerging rules under the Kyoto Protocol University-level training course, e-textbook, e case studies e-marketplace and e-learning e modules New or improved weather/resource databases with NASA, IEA Small Hydro & UNEP- GEF Solar Wind Energy Resource Assessment (SWERA) and updated product database Conclusions Cost-effective opportunities exist Parks Canada PV-Wind Hybrid System (Arctic at 81 N) Project viability depends on a number of factors RETScreen is an annual analysis with monthly resource calculation that can achieve accuracy comparable to hourly simulation models RETScreen makes it much easier to consider RETs at critically important initial planning stage Photo Credit: Ross, Michael 600 kw Wind Turbine installation Photo Credit: Nordex Gmbh PV Phone Photo Credit: Price, Chuck
