Too slow on the drawdown

A German government commission recently proposed to phase out coal by 2038, a goal not in line with the country’s climate targets. Rinscheid and Wüstenhagen find that German citizens prefer to phase out coal by 2025 instead, suggesting that voters want more aggressive climate action than political decision makers.

    For the well informed, taking actions to curb energy consumption from household appliances is uncomplicated. Now, research shows that simple information provision interventions can correct consumer misperceptions of the energy consumed by common appliances, offering hope to the rest of us.

    Copper-doped cadmium telluride thin-film solar cells have high efficiency, but limited hole density and Cu diffusion allow little room for further improvements in device performance. Now, arsenic-doped cadmium telluride thin films show enhanced hole density and lower dopant diffusivity leading to 20.8%-efficient solar cells.

    In the development of Li metal solid-state batteries, understanding the mechanism that governs fundamental processes such as Li stripping and plating is pivotal. Now, researchers uncover a pressure dependence on Li stripping and higher pressures are suggested for faster discharging.

    New network tariffs designed to recover grid operating costs can introduce up to a 500% increase in charges for some households. A transition from volumetric to peak-load-based tariffs will require targeted policy measures such as clear price signals, information about household electricity consumption and temporary compensation or mitigation mechanisms.

    Hotel guests changed their resource-use behaviour when they received feedback on their consumption in real time, even though they did not know that they were part of a study and had no financial incentives. Behavioural interventions provided by digital technologies are a scalable and cost-effective policy instrument for fostering resource conservation.

    Hardware costs, cost of labour, favourable cost of capital, low taxes and low, but positive, profit margins all contributed to lowering the price of utility solar power in the Middle East. These prices and policies can be replicated elsewhere without direct subsidies and prices will continue to reduce in the future.

    Financing costs for renewable energy technologies have decreased substantially over the past 18 years, helping make renewables more cost competitive. Leveraging the effect of financial learning and continuing the policies that facilitated favourable financing conditions are key for greater renewable energy adoption in the future.
