Background

This demonstration project in the Rubavu District of Rwanda focused on retrofitting public lighting with sustainable solutions. This initiative is part of the Urban-LEDS II project, which helps local governments to implement integrated low emission and resilient development. It is implemented by ICLEI and UN-Habitat with funding from the European Commission. The Rubavu pilot provides a model for future sustainable lighting initiatives.

Approach

Sixty solar street lights with twilight sensors were installed, and existing streetlights were retrofitted with energy-efficient LED lamps. As part of the project, a financial model was developed to support the rollout of solar public lighting in Rubavu and potentially other districts in Rwanda.

Environmental Impact

The initiative reduces negative impacts on the natural environment by replacing conventional public lighting sources with more sustainable solutions. Installing solar street lights allows for lighting to be provided with less greenhouse gas emissions, as they do not rely on grid electricity. Retrofitting existing public lights with energy-efficient LED lamps reduces energy consumption and emissions compared to incandescent or fluorescent lamps. Light sensors ensure that the lighting is only activated during the dark, keeping the amount of energy used to a minimum.
