Abstract : The alarming rise in global warming and rapidly depleting non-renewable natural resources have generated ripples of anxiety which are reflected in the widespread research being carried out on alternative, clean and sustainable energy sources. This article highlights the simple innovation of solar bottle lights (SBLs) which can be made, installed and used at grassroots levels as a source of light inside dark settlements, an alternative to electric light bulbs during the daytime. They are especially effective in low- and middle-income countries where the spread of modern technology has been limited. Experiments were conducted by approaching slum dwellers in Dhaka, Bangladesh to install SBLs. Promotional campaigns were run, and the inhabitants were surveyed and interviewed. Acceptance rates and subsequent electric bulb usage were monitored. The research demonstrated that SBLs are highly effective in terms of energy conservation (potentially by up to 171.4 GWh/year across slum areas in Bangladesh) and carbon emissions reduction (by up to 87.9 Million MT/year from slum areas in Bangladesh) depending on different scenarios of use. In accordance with the United Nations Sustainable Development Goal 7 on the access to affordable, reliable, sustainable and modern energy for all, the enormous potential of SBLs as a basis for access to light and effective clean and affordable energy can be unlocked if these devices are produced and consumed at large scale across the globe.
