Innovative stormwater solution unveiled to tackle record rainfall in Denmark

Denmark faced unprecedented rainfall in 2023, breaking historical records and posing ongoing challenges with stormwater and flooding of streets and basements. Rather than resorting to expanding CO2-intensive concrete sewer networks to handle runoff, Professor Marina Bergen Jensen from the University of Copenhagen proposes to manage stormwater at its source and treat it as a valuable resource.

Focusing on how energy is consumed—rather than supplied—could be more helpful in reducing carbon emissions

A new commentary, published in Joule by members of the Energy Demand Changes Induced by Technological and Social Innovations (EDITS) network, coordinated by the International Institute for Applied Systems Analysis (IIASA), highlights that switching the focus from how energy is supplied to how energy is consumed can be a more effective approach to reducing carbon emissions with the added benefit of improving well-being for all.

How extreme weather and system aging affect the US photovoltaic fleet

For photovoltaic (PV) systems—designed to operate over lifetimes of 20, 30, or even 50 years—small losses in energy production can add up to measurable differences over time. These differences can even determine whether a system operates at a profit or loss. Yet, small changes in energy production are frustratingly difficult to measure, especially in the noisy and often incomplete data of a PV system’s production.

Researchers enhance safety of lithium batteries with graft polymerization technique

Lithium-ion batteries are a widely used class of rechargeable batteries in today’s world. One of the processes that can hamper the functioning of these batteries is an internal short circuit caused by direct contact between the cathode and anode (the conductors that complete the circuit within a battery).
