Renewable Energy Technologies (RETs) are considered as one of the main solutions for energy efficiency in face of the climate change issue. Urban areas should contribute to the reduction in consumption of non-renewable energy sources by emphasizing on energy efficient solutions, which can play a vital role in the field of urban design and the nature of the public realm in cities, communities and neighbourhoods.

This paper is concerned with the installation of RETs in the public realm. It aims to analyse the potentiality of installing RETs within the public spaces in addition to its effects and limitations. The paper sheds light on the physical aspects of the public realm, types of RETs and presents a framework identifying the RETs suitability to be used in the public spaces.
