This working paper by the International Renewable Energy Agency (IRENA) considers how renewables and energy efficiency can work together to contribute to global energy decarbonisation by 2050. It also looks and how this synergy affects energy system and technology cost, and the effect it has on air pollution and avoidance of adverse health effects caused by these pollutants.
The paper looks in detail at the five largest energy users – China, Germany, India, Japan and the United States – up to 2030. Together, these five countries represent two-thirds of the G20’s primary energy supply and around half of global energy demand. IRENA’s working paper proposes actions to strengthen synergies as a step towards a sustainable and affordable energy future.
