Why electric vehicles are more sustainable than you might think
On 12.01.2021 by Martin BeuseDespite the recent flood of (non-academic) studies claiming differently, battery-powered electric vehicles (BEV) already provide significant environmental benefits over internal combustion engine (ICE) cars. This gap is only widening, as policy, academia, and industry are coming together to rapidly improve BEVs and battery technology in particular. Read More

How smart grids will change the way architects have to design buildings
On 30.11.2020 by Christoph WaibelIn order to efficiently integrate intermittent renewable energy into our grids, we need to change the role that buildings play in a city. Instead of being mere consumers, they need to become a swarm of smart prosumers capable of stabilizing the grid. This calls for a new way how architects should design buildings, leading to the next era of architecture: “Energy Responsivism”. Read More

Accelerating the energy transition in developing countries: Inclusion of women in clean energy strategies
On 16.10.2020 by Cristina de los Angeles Dominguez HernandezIn rural communities, women are the primary energy users as they are the ones performing household chores such as cooking and domestic work. For this reason, they are the most affected along with children from the use of highly-pollutant conventional fuels. Ironically, most of the time they are excluded from clean energy strategies targeted toward transitioning to clean fuels. My research has shown that gender focused initiatives targeting women can play a major role in accelerating this transition to affordable, safe, and reliable energy. Read More

Navigating towards the future of renewable energy markets
On 08.07.2020 by Maciej SzybiakThe past decade was undoubtedly a great period for renewable energy (RE) sector. In 2019 alone, the total investment in RE projects worldwide amounted to over USD 250 billion, what equals one-third of the Swiss GDP or construction of 170 Wembley stadiums. However, investing is just the first element in the business puzzle. The question now is how to make RE projects profitable or at least non loss-making. Power Purchase Agreements (PPAs) seem to be a promising systematic solution Read More

Jointly owned PV should be the new solar ownership model / Gemeinschaftliches Eigentum: der neue Ansatz für Photovoltaikanlagen in der Nachbarschaft
On 26.06.2020 by Danielle GriegoAs societies transition from using predominantly centralized energy supply sources to increasing dependency on distributed renewable energy generation, it is no longer enough to singularly focus on energy efficiency. In particular, the time sensitivity of electricity generated from solar and wind must also become an integral part of future electric consumption behavior patterns. In this article, I outline how joint ownership of community-scale PV systems have vast potential to establish long-term and intelligent electricity consumption behavior patterns among co-owners.
