Doubling the share of renewables in the global energy mix by 2030 can save up to USD 4.2 trillion annually by 2030 – 15 times more than the costs – according to a new report by the International Renewable Energy Agency (IRENA). REmap: Roadmap for a Renewable Energy Future, released recently at the Berlin Energy Transition Dialogue, recommends options to boost the share of renewable energy in the global energy mix from just over 18% today, to as much as 36% by 2030.
“Achieving a doubling is not only feasible, it is cheaper than not doing so,” said IRENA Director-General Adnan Z. Amin. “REmap shows this is not only the most economic pathway, but also the most socially and environmentally conscious. It would create more jobs, save millions of lives from reduced air pollution, and set us on a pathway to limit global temperature rise to two degrees as agreed in Paris.”
This second edition of IRENA’s global roadmap broadens its analysis to cover 40 countries, representing 80% of global energy use. According to the report, great strides have been made to increase renewables in the power sector, which is on track to generate roughly 30% of the world’s electricity by 2030 (up from 23% today). If a doubling is achieved, this share would grow to more than 50%. There is also great potential to increase renewables in transport, buildings and industry, but these sectors are currently lagging behind.
“The energy transition is well underway in the power sector, but to reach global climate and development targets, the next phase will require more focus on transport, heating and cooling,” said Director of IRENA’s Innovation and Technology Centre Dolf Gielen. “If a doubling is achieved, these sectors would account for roughly half of renewable energy use in 2030 and so must scale-up dramatically to meet that target.”
Under existing national plans, the global renewables share would only reach 21% by 2030. To achieve a doubling, the annual rate of renewable energy deployment would need to increase six-fold and would require an average annual investment of USD 770 billion up to 2030. Achieving this would increase the cost of the global energy system by roughly USD 290 billion per year in 2030, but the savings achieved through this doubling – thanks to avoided expenditures on air pollution and climate change – are up to 15 times higher than this cost.
Key benefits of doubling renewables:
- It would limit average global temperature rise to 2 °C above pre-industrial levels (when coupled with energy efficiency);
- It would avoid up to 12 gigatonnes of energy-related CO2 emissions in 2030 – five times higher than what countries have pledged to reduce through renewable energy in their nationally determined contributions (NDCs);
- It would result in 24.4 million jobs in the renewable energy sector by 2030, compared to 9.2 million in 2014;
- It would reduce air pollution enough to save up to 4 million lives per year in 2030;
- It would boost the global GDP by up to USD 1.3 trillion.
To achieve this goal, the report identifies five priorities for action including:
- Correcting market distortions to create a level playing field;
- Introducing greater flexibility into energy systems to accommodate the variable nature of some forms of renewable energy;
- Developing and deploying renewable energy solutions for heating and cooling in new urban development projects and industry;
- Promoting electric transport based on renewable power and biofuels to reduce air pollution; and
- 5. Ensuring the sustainable, affordable and reliable supply of bioenergy feedstocks.
“The age of renewable energy is here, but without concerted efforts, its potential will not be reached fast enough to meet international climate and development targets,” said Mr. Amin. “For decision makers in the public and private sectors alike, this roadmap sends an alert – both on the opportunities at hand and on the costs of not taking them.”
