Efficient resource management and the development of resilient societies begins with an accurate identification of strengths and weaknesses of systems involved. Conducting a holistic performance analysis considering multiple assessment criteria permits the detection of discrepancies hindering systems productivity. In this study, an integrative assessment tool, based on the analytical hierarchy process (AHP) and the energy, water, and food (EWF) nexus is used to design a decision-making scheme that guides policymakers in establishing national priorities and sectorial strategies.

Reductions in carbon emissions have been a focus of the power sector. However, the sector itself is vulnerable to the impacts of global warming. Extreme weather events and gradual changes in climate variables can affect the reliability, cost, and environmental impacts of the energy supply. This paper analyzed the interplay between CO2 mitigation attempts and adaptations to climate change in the power sector using the Long-range Energy Alternative Planning System (LEAP) model.

We develop roadmaps to transform the all-purpose energy infrastructures (electricity, transportation, heating/cooling, industry, agriculture/forestry/fishing) of 139 countries to ones powered by wind, water, and sunlight (WWS). The roadmaps envision 80% conversion by 2030 and 100% by 2050. WWS not only replaces business-as-usual (BAU) power, but also reduces it ∼42.5% because the work: energy ratio of WWS electricity exceeds that of combustion (23.0%), WWS requires no mining, transporting, or processing of fuels (12.6%), and WWS end-use efficiency is assumed to exceed that of BAU (6.9%).

This paper discusses the CO2 footprint of California's drought during 2012–2014. We show that California drought significantly increased CO2 emissions of the energy sector by around 22 million metric tons, indicating 33% increase in the annual CO2 emissions compared to pre-drought conditions. We argue that CO2 emission of climate extremes deserve more attention, because their cumulative impacts on CO2 emissions are staggering. Most countries, including the United States, do not have a comprehensive a nationwide energy-water plan to minimize their CO2 emissions.
