Though it does not release greenhouse gases during operation, nuclear houses several other ecological risks. This paper looks at voluntary contribution initiatives, community renewable energy generation, and grid modernization, as three areas where initiatives and are being undertaken by utilities that will contribute to a greater portion of Ontario’s electricity demand being met by renewables as opposed to nuclear. Ultimately this paper seeks to determine if initiatives in any of these areas could ultimately lead to an electricity system transition in Ontario away from nuclear towards renewables. Grid modernization appears to have the highest potential to significantly increase the contribution of renewably-sourced electricity to Ontario’s supply. However, utilizing voluntary contribution strategies, and supporting the development of community renewable projects, while unlikely to eventually prompt a large electricity-system change, can meaningfully contribute to goal of increasing the supply of renewably-sourced electricity in Ontario.enNuclear energy--OntarioRenewable energy sources--OntarioMajor paper
