ColdHubs, an innovative Nigerian agricultural enterprise that uses solar-powered refrigerated storage units to keep food from spoiling, is slowly but surely expanding to nearby West African countries. But it faces big challenges to scale up and finance its operations, company founder and CEO Nnaemeka Ikegwuonu told a Harvard Kennedy School audience celebrating the 2022 Roy Award winner.

Surging demand and dizzying price hikes have raised concerns that inadequate metal and mineral supplies may impede the clean energy transition. Given the urgency of reducing fossil fuel use, the science and policy worlds must solve two main challenges: how to ensure the availability and affordability of critical metals in the quantities needed, and how to manage the environmental impacts related to mining and processing them. The latter issue is likely to be much trickier than the former, argue Henry Lee and Xin Sun.

Joshua Schwartz and Sabrina Arias write that although Congress seems unable to act, enough states, cities and counties are mobilizing to make a dent in U.S. carbon emissions. The states, cities, counties, and towns that have committed themselves to upholding the Paris agreement currently release a majority of U.S. carbon emissions. If they do manage to meet their targets, they can make a meaningful difference.

Last week, U.S. Sen. Joe Manchin seemingly dashed Democrats’ hopes for congressional action to slow climate change. Sen. Bernie Sanders accused Manchin of “sabotag[ing] the president’s agenda”; Rep. John Yarmuth, when asked about the consequences of Congress not acting on climate change, said, “We’re all going to die”; and climate activists, as well as some Democrats in Congress, wondered if Manchin should be removed as chair of the Senate Energy and Natural Resources Committee.

The story of Iceland's transition from fossil fuels may serve as an inspiration to other countries seeking to increase their share of renewable energy.

For many, integrating “decarbonization” into public policy, corporate and financial strategies has become a requirement, not an option — yet, what happens when the critical link between climate stability and decarbonization breaks?

Russia’s invasion of Ukraine has amplified the importance of national-security considerations in western countries’ energy policies. At the same time, governments must continue to focus on reducing environmental damage – in particular, on cutting greenhouse-gas emissions. Both goals, geopolitical and environmental, are urgent and should be evaluated together.

The transition to low-carbon energy systems has the potential to shift geopolitical power, as it will create winners and losers across countries. Laima Eicke and Silvia Weko argue that what matters for ‘winning’ transition processes are political and economic factors, such as investments in renewables and technological development, as well as the relative timing of transition processes.

Russian military action in Ukraine could trigger an energy crisis even more serious than the one already hitting Europe. As has been pointed out, should the West hit Russia with severe new sanctions, President Vladimir Putin could cut off natural gas exports, leaving the continent shivering through midwinter. Yet there is another potential weapon of Russia’s that’s been less discussed and might be very effective: An ability to disrupt global oil markets, which would directly hit U.S. consumers.

If you were wondering whether Europe is running out of options to deal with its continuing energy crisis, one of Britain’s largest energy suppliers just offered an answer.
