SDG 7 seeks to increase the share of renewable energy in the global energy mix, double the global rate of improvement in energy efficiency, enhance international cooperation to facilitate access to clean energy research and technology, and expand infrastructure and upgrade technology to supply modern and sustainable energy services for all. A central aim of SDG 7 is to shift from non-renewable energy forms to renewable energy. Non-renewable energy forms include fossil fuels such as coal, oil, and natural gas – which all contribute to high greenhouse gas emissions – and other controversial energy sources such as nuclear power. Forms of renewable energy include solar, hydro, wind, and geothermal. Promoting walking or cycling as modes of urban transport also falls within the scope of SDG 7 (in addition to relating to other goals as well, such as SDG 3: Good health and well-being) as it promotes clean energy.
