US-based group wins 2019 RTC for project to replace polluting fuels with a solar-powered home cooking system

Elsevier and the International Solar Energy Society (ISES), announce that “SUNSPOT Solar Electric Cooking” by Team SUNSPOT is the winner of the second Renewable Transformation Challenge 2019!

“A key to achieving 100% renewable energy and a decarbonized energy system is to accelerate the electrification of all of our end use energy needs,” added Dr. David Renné, imediate past President of ISES. “The electrification of traditional cooking methods in developing countries, which generally rely on the unsustainable use of biomass fuels, will be a significant game changer, and will also help accelerate energy access to all off-grid populations so they can meet their other end use energy needs as well.”

Over 100 entries were received for the biennial challenge. They were scored in terms of applicability, impact, sustainability and scalability in two stages: first by the Juror Panel, and then by the Elsevier-ISES Awards Committee who selected the final winner from the ten shortlisted candidates.

“It was great to see so much great work being done in these proposals from across the world, from Uganda to Portugal, the USA to India, and beyond,” said Adam Fraser, Senior Publisher, of the renewable and sustainable energy journal portfolio, in Elsevier’s energy programme. “By electrifying home cooking systems using solar energy in a cost effective way, Team SUNSPOT can steadily begin to reduce the immediate adverse effects of polluting cooking methods, and make a contribution towards our global efforts to combat climate change. Work such as this is what Elsevier’s energy programme and ISES set out to support: learning from the sort of research we’ve got a strong history of publishing and taking that out into communities to deliver real impact.”
