IRENA: doubling global share of renewable energy by 2030 could save trillions annually from avoided expenditures on pollution and climate change

Doubling the share of renewables in the global energy mix by 2030 can save up to US$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 today 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.

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. 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 US$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—due to avoided expenditures on air pollution and climate change—are up to 15 times higher than this cost.

To achieve this goal, the report identifies five priorities for action including:

  1. Correcting market distortions to create a level playing field;

  2. Introducing greater flexibility into energy systems to accommodate the variable nature of some forms of renewable energy;

  3. Developing and deploying renewable energy solutions for heating and cooling in new urban development projects and industry;

  4. 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.



Not so sure that ALL long term extra health care cost, shorten useful life span cost and multiple property damages cost from climate changes have been added?

At 15 times the cost of remedial actions, it would still be an excellent investment?

However, the $XXT required would have to come from polluting agents and/or polluters. A worldwide progressive carbon and pollution tax may be required.
