Allocating Transmission to Mitigate Market Power in Electricity Networks [PDF]
We ask what conditions transmission contracts increase or mitigate market power. We show that the allocation process of transmission rights is crucial. In an efficient arbitraged uniform price auction, generators will only obtain contracts that mitigate ...

Advanced Functional Materials, EarlyView.Graded refractive index (GRI) structures are prepared from the layer‐by‐layer spray coating of the mesoporous SiO2 nanoparticles, showing high solar transparency and thermal emissivity. Under outdoor conditions, after 50 days, the GRI‐coated photovoltaics show on average 6.65 ± 1.48 °C lower than that of the non‐coated references, maintaining 80.9 ± 8 ...

Why Tax Energy? Towards a More Rational Energy Policy [PDF]
The same fuels are taxed at widely different rates in different countries while different fuels are taxed at widely different rates within and across countries. Coal, oil and gas are all used to generate electricity, but are subject to very different tax

Allocation of Carbon Emission Certificates in the Power Sector: How generators profit from grandfathered rights [PDF]
To meet its Kyoto requirements, the EU will establish an internal market for carbon dioxide allowances from 2005, the EU Emissions Trading Scheme (ETS). National governments are to allocate most of these allowances for free.

Photo‐Assisted Zn‐Iodine Battery via Bifunctional Cathode with Iodine Host and Solar Response Boost
Advanced Functional Materials, EarlyView.A bifunctional cathode based on BiOI materials is developed for photo‐assisted Zn‐iodine batteries, serving as both an iodine host and a solar‐responsive material. This design enables dual reaction routes involving vacancy‐based iodine storage and reversible two steps iodine redox.
