Solar has greater techno-economic resource suitability than wind for replacing coal mining jobs

Coal mining directly employs over 7 million workers and benefits millions more through indirect jobs. However, to meet the 1.5 °C global climate target, coal's share in global energy supply should decline between 73% and 97% by 2050. But what will happen to coal miners as coal jobs disappear ?Answering this question is necessary to ensure a just transition and to ensure that politically powerful coal mining interests do not impede energy transitions. Some suggest that coal miners can transition to renewable jobs. However, prior research has not investigated the potential for renewable jobs to replace 'local' coal mining jobs. Historic analyses of coal industry declines show that coal miners do not migrate when they lose their jobs. By focusing on China, India, the US, and Australia, which represent 70% of global coal production, we investigate: (1) the local solar and wind capacity required in each coal mining area to enable all coal miners to transition to solar/wind jobs; (2) whether there are suitable solar and wind power resources in coal mining areas in order to install solar/wind plants and create those jobs; and (3) the scale of renewables deployment required to transition coal miners in areas suitable for solar/wind power. We find that with the exception of the US, several GWs of solar or wind capacity would be required in each coal mining area to transition all coal miners to solar/wind jobs. Moreover, while solar has more resource suitability than wind in coal mining areas, these resources are not available everywhere. In China, the country with the largest coal mining workforce, only 29% of coal mining areas are suitable for solar power. In all four countries, less than 7% of coal mining areas have suitable wind resources. Further, countries would have to scale-up their current solar capacity significantly to transition coal miners who work in areas suitable for solar development.

Securitization of energy supply chains in China

Three sources of energy security risks, namely sovereignty, robustness and resilience, affect China’s energy chains. Energy security issues in China both have shaped and at the same time were shaped by ideas and institutions. China remains rigid with equating ‘security’ with ‘national security’ and the notion of “national” is socially constructed. Powerful actors, such as Chinese NOCs, inclined to interpret the problem so that it fits their preferred solution. Securitization of any energy supply chains results from their historical roots, system properties and institutional agents.

Energy security of China, India, the EU and the US under long-term scenarios: results from six IAMs

Energy security of China, India, the EU and the US under long-term scenarios: results from six IAMs. Climate Change Economics, 4(4), 1340011. Gated.

This paper assesses energy security in three long-term energy scenarios (business as usual development, a projection of Copenhagen commitments, and a 450 ppm stabilization scenario) as modeled in six integrated assessment models: GCAM, IMAGE, MESSAGE, ReMIND, TIAM-ECN and WITCH. We systematically evaluate long-term vulnerabilities of vital energy systems of four major economies: China, the European Union (E.U.), India and the U.S., as expressed by several characteristics of energy trade, resource extraction, and diversity of energy options. Our results show that climate policies are likely to lead to significantly lower global energy trade and reduce energy imports of major economies, decrease the rate of resource depletion, and increase the diversity of energy options. China, India and the E.U. would derive particularly strong benefits from climate policies, whereas the U.S. may forego some opportunities to export fossil fuels in the second half of the century.
