1. Solar Water Heating for Climate Protection: The Role for Carbon Finance Presented At: COP11 MOP 1, Montreal Canada 30 November 2005 By: Steven Kaufman Green Markets International, Inc.

2. Presentation Overview  Solar Water Heating & Climate Protection  Baseline Conditions in Six Countries  Market Barriers & Carbon Finance Potential  Solar Water Heating CDM Project Ideas & Example  Conclusions

3. Innovative Financing for Solar Water Heating Green Markets International is a non-profit organization working to boost sustainable energy for climate protection and development. As one activity, we are coordinating a project to advance financial and commercial innovations for solar water heating in Brazil and the Caribbean region. Project partners include:  Vitae Civilis Institute, Brazil  Caribbean Solar Technologies, Anguilla Project sponsors include:  Renewable Energy & Energy Efficiency Partnership  Blue Moon Fund  Oak Foundation

4. Innovative Financing for Solar Water Heating The initiative involves the following components:  Developing model business plans for SWH ESCO and fee-for-service operations in Brazil and the Caribbean region  Helping stakeholders to understand opportunities for carbon trading and prepare SWH CDM projects  Exploring international REC trading possibilities

5. Water Heating Contribution to Energy Use Water heating contributes substantially to overall energy end use in many countries and is responsible for a significant amount of greenhouse gas emissions  In China, roughly 25% of household energy consumption is for water heating  For India’s residential sector, water heating accounts for about 25% of household electricity consumption  In the Mexico City Metropolitan Area, water heating is estimated to account for about 43% of all LPG consumption  In South Africa, water heating accounts for 40% or more of domestic energy use  In the United States, water heating accounts for about 20% of energy use in households and 15% in commercial buildings

12. Impediments to Growth of Solar Water Heating Markets  High upfront cost vs. conventional water heaters  Lack of available financing options  Low awareness about lifecycle financial benefits  Quality control problems in some markets

13. Carbon Finance Benefits for Project Developers Emission reduction sales can help to overcome financial and other barriers by:  Supplying an additional revenue source  Improving project economics (increasing IRR)  Enhancing project viability in other ways (e.g., emission reduction purchase commitment from creditworthy buyer can increase confidence on the part of other prospective investors)

14. Solar Water Heating CDM Project Ideas CDM participation and CER revenue can potentially boost solar water heating projects and markets by:  Helping to secure commercial or government-supported loans for consumers’ SWH purchases  Improving project economics and helping to leverage capital for commercial fee-for-service operations  Contributing to capital costs or supporting the implementation of public or private SWH initiatives in other ways

15. Potential CER Revenue: Solar Water Heating

16. Conclusions  Water heating accounts for a significant portion of total energy use among households, businesses and industries, in some cases 30% or more. Thus, the potential for carbon abatement from solar water heating is substantial  The carbon intensity of baseline fuels for conventional water heating varies but is considerable in many locations  Solar water heating systems are usually more cost-effective than photovoltaic applications as a greenhouse gas reduction measure and can be comparable to wind farms and hydroelectric facilities. Solar water heating is particularly competitive where system costs are comparatively low and where the carbon intensity of the baseline fuel is high  Solar water heating activities can generate substantial revenue from carbon market participation. In some locations, undiscounted revenue flows could equal 25–50% or more of system costs at $10 per ton of CO2 and 14 year crediting
