Energy supply is inevitably linked to this challenge. Energy and its appropriate availability to all people can boost economic development and human well-being (e.g. cooking, heating, cooling, lighting, transportation). But it could also worsen the adverse impacts such as climate change, air pollution, and regional disparities.
