Deploying photovoltaic (PV) systems in desert regions can support both decarbonization and ecological restoration, but conventional photovoltaic-to-grid (PVtG) strategies face increasing integration costs, curtailment, and value deflation as deployment...

The Paris Agreement has accelerated global climate action, prompting countries to formulate policies that steer buildings toward net-zero carbon emissions. This review critically examines the practical definitions of “net zero” in the building sector by...

Green methanol could help decarbonize transport and industry, but its production roadmap remains uncertain because biomass conversion, renewable hydrogen supply, the emissions and cost of electricity are tightly coupled. Here we show, using pilot-scale...

Renewable energy droughts, characterized by prolonged periods of low winds and reduced solar irradiance, threaten the stability of electricity supply, with fossil fuel plants expected to cover much of the energy deficit. By integrating an electricity...

This paper examines how natural disasters complicate government efforts to balance energy security with the energy transition in regulated electricity systems. Using random variations in runoff as a natural experiment, we find that droughts lead to a long...
