Conclusions
• Limited original data, frequent recursive referencing;
• Wide range of reported employment factors;
• Limited comparison of renewables versus conventional generation;
• Focus on OECD countries in current literature
• In the Middle East, renewable energy is estimated to stimulate 155,000 to 180,000 direct jobs by 2050.
• A domestic manufacturing and installation industry creates as many jobs as O&M in 2050;
• Job creation can be an important co-benefit of renewable energy deployment, but is less convincing as a core argument
