Sustainable energy, economic growth and public health

Dramatic economic growth over the last 50 years has been accompanied by widening inequalities world‐wide in wealth and energy consumption, diminished life expectancy in some countries, and deteriorating indices of environmental sustainability including loss of bio‐diversity. Raised output of carbon dioxide (CO₂) and other greenhouse gases due to increased economic and industrial activity is causing progressive climate change, leading in turn to direct and indirect adverse effects on health. Emissions of greenhouse gases can be lowered by increased use of renewable energy sources, for example, wind power in the United Kingdom (UK), greater energy efficiency and other measures to promote sustainability. The experience of some developing countries shows that favourable indicators of health and development can accompany a low output of greenhouse gases. It is unclear whether contemporary political and social systems can deliver improved human development without increased use of fossil fuels and other resources.
