  • Hard to decarbonize homes represent a complex problem that has historically been neglected in favour of the lower hanging fruit of easier to treat properties. To enable an equitable net zero transition, we must understand these homes in a holistic manner take into account the impacts of different routes to decarbonization on occupants.

  • Critics have opposed clean energy public investment by claiming that governments must not pick winners, green subsidies enable rent-seeking behaviour, and failed companies means failed policy. These arguments are problematic and should not determine the direction of energy investment policies.

  • The European Union’s plan to phase out Russian natural gas imports by 2027 rests partly on increasing near-term imports of US liquefied natural gas. This will require a coordinated policy response that includes securing supplies from major exporters, global diplomacy, expanding import capacity, and alignment with Europe’s climate goals.

  • The Russia–Ukraine crisis has exposed vulnerabilities in US energy security. The US may import only a small amount of Russian oil but it is tied to Russian energy via its participation in highly globalized supply chains.

  • Innovative user-centred energy business models will be critical to deliver millions of zero-carbon assets in homes and businesses and to help customers with complex energy prices. These new business models require regulatory space to emerge while regulation itself will need to change to protect consumers from harm.

  • Decarbonizing the built environment sector is key to reducing global greenhouse gas emissions, yet there are major barriers to the adoption of emerging energy technologies in buildings. Building demonstrators could help overcome such barriers by trialling technologies and engaging experts across research, construction and policy.

  • The United States and other G7 countries are considering a framework for mandatory climate risk disclosure by companies. However, unless a globally acceptable hybrid corporate governance model can be forged to address the disparities among different countries’ governance systems, the proposed framework may not succeed.

  • The scientific research environment struggles to be an inclusive and diverse place. Initiatives such as the Minority Carriers event at the Photovoltaics Specialists Conference not only support marginalized researchers but also delineate the changes that need to be made and actions that should be taken to make the research space inclusive.

  • As increasingly complex and optimized energy systems prepare to cope with a variety of risks including climate shocks and extreme weather events, a myopic focus on economic efficiency can significantly jeopardize critical energy services.

  • The recent ruling in a Dutch court that Shell must curb its CO2 emissions is the latest in a series of legal moves bringing human rights concerns to bear on energy activities. This trend will have profound consequences for energy developments and for meeting climate goals.

  • Established climate mitigation scenarios assume continued economic growth in all countries, and reconcile this with the Paris targets by betting on speculative technological change. Post-growth approaches may make it easier to achieve rapid mitigation while improving social outcomes, and should be explored by climate modellers.

  • Energy and transportation researchers can contribute to the realization of just transitions to low-carbon mobility in cities across the planet by elaborating and enacting broad conceptions of justice that consider distribution, procedure, recognition and knowledge generation.

  • Stopping climate change requires revolutionary transformations in industry and agriculture. Ahead of several major climate meetings this year, policymakers struggling to measure progress on climate change should focus less on global emissions, which will be slow to change, and more on technological advances in pioneering niches.

  • 11 March 2021 marked the tenth anniversary of the Fukushima Daiichi nuclear power plant accident. Today, without better public engagement and understanding of nuclear power generation and its role in the energy system mix, progress on Japan’s post-carbon strategy will remain stagnant.

  • Energy research works with units and concepts forged in an age of fossil fuel, leading to problem formulations that reinforce current societal practices and patterns of consumption. Achieving low-carbon energy goals depends on shifting demand to match supply and reconceptualizing interactions between time and energy.

  • The power conversion efficiency of organic solar cells has rapidly increased, yet significantly less attention has been paid to materials stability and device longevity. For organic solar cells to make an impact in the marketplace, researchers, funding agencies and journals should do more to address this crucial gap.

  • The Paris Agreement’s Mission Innovation initiative to accelerate government spending on clean energy research is currently succeeding in its quest to support carbon mitigation. It should be renewed for an additional five years, with increased ambition, and changed to better integrate the private sector.

  • Roughly 90% of the world’s energy use today involves generation or manipulation of heat over a wide range of temperatures. Here, we note five key applications of research in thermal energy that could help make significant progress towards mitigating climate change at the necessary scale and urgency.

  • Online conferences are increasingly popular within scientific communities due to the travel restrictions faced by many countries. Although a relatively new phenomenon for many of us, lessons from recent meetings provide useful reflections on the format’s opportunities and challenges compared to conventional in-person meetings.

  • Energy plays a central role in responding to emergencies such as the COVID-19 pandemic, from ensuring adequate healthcare services to supporting households during lockdowns. Protecting the renewable energy industry and its contribution to providing sustainable energy access for all must be an urgent priority in the current crisis.
