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
