New modelling forecasts 46 million jobs by 2050 in a 100% renewable energy scenario

achieving paris goals teske coverA newly-released book, Achieving the Paris Climate Agreement Goals, provides detailed discussion of the the implications, including job implications,  of a transition to 100% renewable energy.  The  book’s findings are summarized by Sven Teske of the Institute for Sustainable Futures, University of Technology Sydney, in “Here’s how a 100% renewable energy future can create jobs and even save the gas industry”,  which appeared in The Conversation (Jan. 23). That article states: “The world can limit global warming to 1.5℃ and move to 100% renewable energy while still preserving a role for the gas industry, and without relying on technological fixes such as carbon capture and storage, according to our new analysis.” The scenario is built on complex modelling – The One Earth Climate Model  – and foresees a gradual transition from gas to hydrogen energy, so that “by 2050 there would be 46.3 million jobs in the global energy sector – 16.4 million more than under existing forecasts….  Our analysis also investigated the specific occupations that will be required for a renewables-based energy industry. The global number of jobs would increase across all of these occupations between 2015 and 2025, with the exception of metal trades which would decline by 2%. ”

The article summarizes a book with a daunting title:  Achieving the Paris Climate Agreement Goals: Global and Regional 100% Renewable Energy Scenarios with Non-energy GHG Pathways for +1.5°C and +2°C . It is the culmination of a two-year scientific collaboration with 17 scientists at the University of Technology Sydney (UTS), two institutes at the German Aerospace Center (DLR), and the University of Melbourne’s Climate & Energy College, with funding provided by the Leonard DiCaprio Foundation and the German Greenpeace Foundation.   It was published in January 2019 by Springer as an Open Access book , meaning it is free to download the entire book or individual chapters without violating copyright.  Of special interest:  Chapter 9,  Trajectories for a Just Transition of the Fossil Fuel Industry , which provides historical production data for coal, oil and gas production, discusses phase-out pathways for each, and concludes with a discussion of the need “to shift the current political debate about coal, oil and gas which is focused on security of supply and price security towards an open debate about an orderly withdrawal from coal, oil and gas extraction industries.”

The data presented in Chapter 9 form the foundation of Chapter 10,  Just Transition: Employment Projections for the 2.0 °C and 1.5 °C Scenarios . This consists of quantitative analysis, ( the overall number of jobs in renewable and fossil fuel industries) and occupational analysis – which looks into specific job categories required for the solar and wind sector, and the oil, gas, and coal industry. The chapter provides projections for jobs in construction, manufacturing, operations and maintenance (O&M), and fuel and heat supply across 12 technologies and 10 world regions. The conclusion:  “Under both the 1.5 °C and 2.0 °C Scenarios, the renewable energy transition is projected to increase employment. Importantly, this analysis has reviewed the locations and types of occupations and found that the jobs created in wind and solar PV alone are enough to replace the jobs lost in the fossil fuel industry across all occupation types. Further research is required to identify the training needs and supportive policies needed to ensure a just transition for all employment groups.”

Models Predict the Effect of Heat Stress on Workers

A scientific article by researchers at the U.S. National Oceanic and Atmospheric Administration uses historical climate data from 1860 and modeling to 2200 to forecast “wet-bulb temperatures” – a heat stress indicator that takes humidity into account. They estimate that if carbon dioxide levels keep rising over the next two centuries, labour capacity during the hottest months will fall from a current level of approximately 90% to 80% by 2050, 63% by 2100 and 39% by 2200, in the worst case scenario. Although the worst effects would be felt in tropical and mid-latitudes, the authors predict that “heat stress in Washington D.C. becomes higher than present-day New Orleans, and New Orleans exceeds present-day Bahrain.”
