    Climate change will affect both the demand for electrical power and the generating capabilities of hydropower plants. Here the authors investigated the combined impact of these effects in the US Pacific Northwest by considering the dynamics of the regional  power grid, where they reveal a profound impact of climate change on power shortfall risk by the year 2035.

    Energy security is an important policy objective across Europe. Public concern about energy security varies across countries due to differences in national energy context and more general national indicators of economic and human well-being, over-and-above individual population characteristics.

    Hydropower is critical to eastern and southern Africa but it is at risk from climate variability. Conway et al. examine river basins and rainfall variability to explore potential hydropower disruption for present and planned generation sites, highlighting the risks to supply and their spatial interlinkages.

    Electricity grids are susceptible to damage from climate-related incidents, which can cause power outages. This study shows that the value of uninterrupted electricity supply across 19 EU nations is related to local temperature, with summer power outages becoming more costly with global warming.

    Biofuels have lower CO2 emissions than fossil fuels, but competing land demands can limit expansion of production. This study shows Brazilian sugarcane ethanol could displace up to 13% of global crude oil consumption by 2045 whilst balancing forest conservation and future land demand for food.

    Climate policies are frequently argued to achieve energy independence as an additional benefit. Jewell et al. use five energy-economy models to show that the opposite is not true: constraining energy imports is much cheaper than climate change mitigation but would not significantly reduce emissions.

    The concept of energy security is multifaceted, and can cover a number of seemingly distinct energy- and climate-related risks. Now, research shows that public opinion about energy security reflects the geographic variation in these risks, such that cross-country differences in public concern are explained by national energy context and indicators.

    Hydropower represents about 20% of sub-Saharan electricity, and expansion is underway. Rainfall varies year-to-year in geographical clusters, increasing the risk of climate-related electricity supply disruption in dry years.

    While tackling interdependencies among food, energy, and water security is promising, three fundamental challenges to effective operationalization need addressing: the feasibility of science-policy integration, cross-scale inequalities, and path-dependencies in infrastructure and socio-institutional practices.

    The US plays a key role in shoring up European energy security and this is unlikely to change dramatically after the November 2016 elections. However, the outcome could compound longer term risks to an internationally engaged US energy policy, affecting European energy security and diplomacy.

    Combatting climate change is often considered to bring about security of energy supply by reducing reliance on imports. By modelling the impact of pursuing energy security policies, a study now finds that the inverse situation is less advantageous for the global climate.
