About the Challenge

The Renewable Transformation Challenge is awarded every two years to recognize accomplishments by organizations such as private enterprises, NGO’s, and research institutions for undertaking projects and programs that help move the world toward an energy system supplied entirely by renewable energy sources, or for conducting the critical analyses that provide meaningful roadmaps for the transformation. The award is one step towards furthering ISES’ vision of a world powered by 100% renewable energy, used efficiently and wisely, and accessible for all. This vision requires a global transformation of our energy systems to efficient and affordable renewable energy and can only be achieved through private and civil society initiatives towards innovative and successful programs that adopt the use of renewable energy technologies, and the intelligent application of energy efficiency measures. In the context of this Challenge, the energy transformation applies to all end-use energy consumption: power, heat, and transport.

Applications for this Challenge are invited from organizations who can demonstrate that they have established successful projects, innovative technologies, financing schemes, policy initiatives, or renewable energy programs, or from institutions that have undertaken research and analyses and identified solutions that demonstrate how this goal is being met. The Renewable Transformation Challenge can include either supply side (energy generation for end-use energy consumption) or demand side (including energy efficiency) programs, or both, and applicants may address any or all of the end-use energy sectors mentioned above.

Applications must demonstrate applicability, impact, sustainability and scalability in how they support the renewable energy transformation to achieve 100% renewables at local, regional or global scales. Innovative ideas will be given preference over incremental improvement projects.

2019 Winner

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), are pleased to announce today that “SUNSPOT Solar Electric Cooking” by Team SUNSPOT is the winner of the second Renewable Transformation Challenge!


The Renewable Transformation Challenge, launched in 2017, aims to honor and showcase outstanding work that actively supports the transformation to a world powered by renewable energy and has potential to widen access to energy, particularly in developing countries. The challenge was open to individuals and organizations in both not-for-profit and commercial sectors worldwide.

Douglas Danley, from the winning group, explained, “the combination of low-cost PV modules, efficient consumer-grade electric cooking appliances and innovative microfinancing have made it possible to introduce the SUNSPOT, a solar-electric cooking system that competes cost-effectively with traditional biomass stoves”.

The scale of the problem that Douglas Danley and his team set out to solve is massive. According to the World Bank, three billion people across the world are still using basic biomass fuels like wood or dung for cooking, with significant negative impacts on their health, the environment, and their social and economic potential. “Benefits of SUNSPOT”, Danley said, “include lowered carbon emissions and reduced pressure on local forests, but, most importantly, elimination of smoke from traditional fires and other quality-of-life improvements for the women and children most directly involved in cooking,” freeing up time currently used in collecting fuel, users will be able to spend more time on socially beneficial activities like education and commerce.

“We look forward to working with partners around the world to scale this technology and help achieve the RTC goal of moving the world toward an energy system supplied entirely by renewable energy sources. The SUNSPOT team is honored to be selected as the winner of the Elsevier & International Solar Energy Society 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, 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.”

Here we present the final Top 10 entries for the Renewable Transformation Challenge 2019, in no particular order below:

2017 Winner

Congratulations to Dr. Sebastian Groh of ME SOLshare Ltd., winner of the inaugural Renewable Transformation Challenge!

Dr. Groh wins the award for the project The Energiewende 3.0 - Smart P2P Solar Grids. In short, A SOLshare grid is created when rural households or SMEs agree on setting up a “swarm network” that consists of existing and new solar home systems (SHSs) and storage devices and enables the interconnection of larger loads. ME SOLshare provides a peer-to-peer solar energy trading platform empowering individuals and SMEs to become solar entrepreneurs offering pay-as-you-go and cash-in-as-you-go electricity solutions to low-income households. ME SOLshare therefore has potential to play a crucial role in supporting rural development and providing a means of direct income to rural communities.

“Elsevier were impressed by the project’s potential to positively impact people and the planet – reducing the cost of energy access; supporting women who are the main energy consumers during trading hours; creating solar entrepreneurs and social empowerment; and reducing greenhouse gas emissions from energy generation by increasing use of renewables and reducing reliance on unsustainable energy sources such as kerosene and diesel,” said Katherine Eve, Executive Publisher of Elsevier’s renewable and sustainable energy journal portfolio. “By backing community projects like SOLshare, Elsevier, in collaboration with our partners such as ISES, continues to play a significant role in supporting the UN Sustainability Development Goals.”

“ISES is very excited about this award, and the groundbreaking work being undertaken by ME SOLshare. A major key toward achieving 100% renewable energy globally is for there to be effective business models that provide reliable and clean energy access for all, including the 1.2 billion people around the world who currently do not have access to electrification services,” added Dr. David Renné, President of ISES. “We are confident that ME SOLshare’s efforts will make major strides toward achieving clean energy goals in off-grid regions.”

Dr. Groh, on behalf of ME SOLshare, will receive a monetary prize of €20,000, one ISES Gold membership, and one free registration to the Solar World Congress 2017 in Abu Dhabi where he will be presented with the Award during the conference dinner on 1 November 2017.

The winner explained “ME SOLshare plans to use the Renewable Transformation Challenge Award fund to kick-start a new pilot project to support clean energy transportation. By upgrading the existing SOLshare swarm grids to create a multiplier effect, SOLshare will offer free solar charging for the over 800,000 battery rickshaw drivers in rural Bangladesh. The equivalent of the charging cost will be credited to the SHS owners in the SOLshare grids who will jointly provide the charging and receive the financial return.”
