2 Renewable Energy Study  Assess the feasibility and potential of wider application of new and renewable energy technologies in Hong Kong  The study comprised of two stages will be completed in early 2004

3 Stage 1 of Renewable Energy Study  Evaluation of new and renewable energy technologies appropriate for local use  Identification of practical measures to support the introduction of new and renewable energy technologies  Formulation of recommendations for development of an implementation strategy

4 Major Findings of Stage 1 Renewable Energy Study (1)  Technologies with potential for wide-scale local application are solar power, wind power, energy from waste and building integrated fuel cells  There may not be suitable sites for implementing large scale renewable energy projects due to geographical constraints

5 Major Findings of Stage 1 Renewable Energy Study (2)  There may be concerns about the environmental and safety impacts of some renewable energy systems  Renewable energy appears to be comparatively more expensive than conventional power

6 Major Findings of Stage 1 Renewable Energy Study (3)  Creation of a positive market for renewable energy projects is essential  Access to utility grid by third party may not be permitted  Public support is a critical factor

7 Stage 2 of Renewable Energy Study  A project to install building integrated photovoltaic (BIPV) systems at Wanchai Tower  Serves as a demonstration to educate the public on the potential use of solar power  Installation work completed in late 2002 and performance of the systems will be monitored until early 2004
