Extreme Weather Events and Agricultural Total Factor Productivity Growth

Southern Economic Journal, EarlyView.
ABSTRACT The productivity of the agricultural sector is crucial for food security in a changing climate. This study estimates the impacts of extreme weather events on agricultural total factor productivity (TFP) growth, contributing to a more comprehensive understanding of the effects of climate change on agriculture.

Reconsidering solar grid parity

Grid parity-reducing the cost of solar energy to be competitive with conventional grid-supplied electricity-has long been hailed as the tipping point for solar dominance in the energy mix. Such expectations are likely to be overly optimistic. A realistic

Bridging the financial gap: Analysis of parity prices and policy instruments for green hydrogen applications in hard-to-abate sectors in Germany

Next Energy
Green hydrogen technologies are crucial for decarbonizing hard-to-abate sectors in Germany. This paper applies a cost-based analytical framework to quantify financial gaps between projected green hydrogen supply costs and sector-specific parity prices ...

Modeling the Thermal Properties of Hydrogen‐Based Direct Reduced Iron Using Computational Thermodynamics and Machine Learning

steel research international, EarlyView.
Hydrogen‐based direct reduced iron (H‐DRI) melts differently from scrap and carbon‐bearing DRI. This work combines differential scanning calorimetry experiments, FactSage thermodynamics, and simple composition‐based regression to predict solidus, liquidus, heat capacity, and enthalpy for H‐DRI.

Grid parity of solar energy: imminent fact or future's fiction?

, 2016
Summarization: One of the major questions related to renewable energy systems is whether we are approaching solar grid parity or not. Solar based power generation will play an important role in future sustainable energy mixes due to its high reliability,

Isotopic evidence for the consumption of Galliformes by the red fox (Vulpes vulpes) in rural southern England

Wildlife Biology, EarlyView.
Anthropogenic resource subsidies can drive mesopredator population growth, altering predator–prey dynamics. The red fox Vulpes vulpes is a generalist canid that can readily exploit such subsidies. In the UK, tens of millions of pheasants Phasianus colchicus and red‐legged partridges Alectoris rufa are released annually for sport shooting, potentially ...

Ensuring greenhouse gas reductions from electric vehicles compared to hybrid gasoline vehicles requires a cleaner U.S. electricity grid

Scientific Reports
Emissions from electric vehicles depend on when they are charged and which power plants meet the electricity demand. We introduce a new metric, the critical emissions factors (CEFs), as the emissions intensity of electricity that needs to be achieved ...

Cost dynamics of onshore wind energy in the context of China's carbon neutrality target

Environmental Science and Ecotechnology
Wind energy has become one of the most important measures for China to achieve its carbon neutrality goal. The spatial and temporal evolvement of economic competitiveness for wind energy becomes an important concern in shaping the decarbonization pathway

Ionothermal Synthesis of Cu(Sb2Se3)[AlCl4] and Cu5(Bi2Se3)6[AlCl4]5 : Monolayers of Sb2Se3 and Bi2Se3 Stabilized by Cu[AlCl4]

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
Ionothermal synthesis in Lewis‐acidic ionic liquids (ILs) yields two new low‐dimensional pnictogen–selenide networks cocrystallized with Cu[AlCl4]. Both are narrow‐gap semiconductors that exhibit strong absorption throughout the visible range. Topochemical AlCl3 extraction triggers partial delamination, pointing to a viable route toward 2D derivatives.
