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.

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”.

Beyond more Chargers for Electric Vehicles in Zurich
On 10.11.2020 by Gracia BrückmannThe conventional wisdom is that to increase battery electric vehicle (BEV) uptake, we need more charging points. However, when we spoke with citizens, car dealership representatives, representatives from car import companies, and local government about the challenges and opportunities for BEVs in Zurich, they mention different challenges, too, and present solutions to overcome them e.g., including BEVs in coherent sustainable transport systems and reducing political uncertainty.

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.

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

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.

The long way ahead for the energy transition
On 22.04.2020 by Viktoras KulionisConcerns about the consequences of excessive global warming have increased interest in the energy transition. General belief is that the energy transition has been the dominant factor of the increased use of renewable energy. However, only few countries/regions show evidence of an actual energy transition. At the global level, its relevance is short of non-existent when you do the math.

Energy: It’s everywhere, yet we don’t talk about it
On 24.09.2019 by Florian Manuel EgliWelcome! You have found the Energy Blog @ ETH, a newly founded initiative to foster a debate around energy research and policy. We know there is fascinating work coming out of ETH Zurich, but often the work is very specific and its implications for society, policymakers, and individuals do not easily get across. Given the unprecedented challenges to transform our energy system, academic ivory towers do not work. We are here to break them up and mix science with policy and society.
