  • Without additional support policies, clean cooking could become unaffordable for about 470 million people by 2030 if a post-pandemic recovery is slow, and about 200 million people by 2030 under ambitious climate mitigation action. Acceleration of clean cooking transitions by tapping into pandemic recovery and climate funds to target the poorest people and regions globally is urgently needed.

  • Innovative energy business models, such as peer-to-peer trading or energy as a service, are attractive to different groups of customers. Disengaged consumers with low trust in the energy market could face further disadvantages, while already active consumers could reap even greater benefits, which risks widening existing socio-economic inequalities.

  • Wind energy repowering decisions are multifaceted and depend on the physical, political and social landscape, as factors such as noise regulation, aesthetics and political bargaining can significantly influence project development. Policy should recognise that a technology perspective alone cannot inform implementation pathways and should be supplemented with an understanding of the political and social dimensions.

  • Households reduced their electricity use the most when they learnt both that they were using more energy than their neighbours and that energy conservation was socially approved. This suggests that efforts to use social information to nudge conservation should combine different types of social feedback to maximize impact.

  • Startups funded by the US Advanced Research Projects Agency – Energy filed patents at twice the rate of similar cleantech firms. The high-risk high-reward funding model has succeeded in advancing energy technology, but more is needed to help these innovative firms cross the valley of death and bring new cleantech products to market.

  • While the Pradhan Mantri Ujjwala Yojana has been instrumental in increasing India’s liquefied petroleum gas adoption, sustained use depends on factors such as regularity of income and ease of access to free-of-cost biomass. To ensure sustained use after adoption, interventions in clean cooking energy must tie in with broader rural development.

  • Retiring, transitioning or installing more stringent emissions controls in coal-fired power plants has the potential to decrease asthma attacks and asthma-related emergency department visits and hospitalizations in nearby communities. These health co-benefits should be considered in policy and decision making about coal-fired power plant retirement or retrofit.

  • Mandatory building energy audits in New York City lead to a modest reduction of energy use of 2.5% and 4.9% for multifamily and office buildings, respectively. This suggests that other approaches besides mandatory audit policies, such as building energy grading and carbon intensity targets, may be needed to achieve sustainability goals.

  • Non-market effects, such as strategic decisions by the Organization of the Petroleum Exporting Countries, energy legislation and speculative bubbles, move crude oil prices away from the level implied by supply and demand for extended periods. These effects should be more proactively monitored and regulated to suit national and international objectives.

  • Community energy groups can raise citizen finance for renewable energy projects at lower interest rates than from commercial lenders, but they often depend on price guarantee schemes. Policies providing price stability and business model innovations are needed to realize the sector’s potential contribution to the zero-carbon energy transition.

  • Although India’s Ujjwala programme has encouraged adoption of modern cooking gas, households have not shifted away from using highly polluting solid fuels. Additional incentives to encourage regular use of cooking gas are necessary to enable a more rapid and complete transition to clean cooking fuel among poor rural households.

  • The elderly and those with disabilities face greater increases in electricity bills and worse health outcomes under some time-of-use electricity rates. This suggests that vulnerable groups should be considered separately in time-of-use rate design, and future rate designs should be tested to ensure that they do not increase hardship.

  • While a government commission recently proposed to phase out coal in Germany by 2038, voters would prefer a phase-out by 2025. Policymakers may underestimate public willingness to support an expedited transition away from high-carbon sources of energy.

  • Many electricity markets authorize capacity payments to generators to secure sufficient supply, unintentionally favouring peaking technologies like oil and gas. New approaches are needed to ensure reliability without discouraging investment in low-carbon resources such as solar, wind and nuclear.

  • Financing costs for renewable energy technologies have decreased substantially over the past 18 years, helping make renewables more cost competitive. Leveraging the effect of financial learning and continuing the policies that facilitated favourable financing conditions are key for greater renewable energy adoption in the future.

  • Hotel guests changed their resource-use behaviour when they received feedback on their consumption in real time, even though they did not know that they were part of a study and had no financial incentives. Behavioural interventions provided by digital technologies are a scalable and cost-effective policy instrument for fostering resource conservation.

  • New network tariffs designed to recover grid operating costs can introduce up to a 500% increase in charges for some households. A transition from volumetric to peak-load-based tariffs will require targeted policy measures such as clear price signals, information about household electricity consumption and temporary compensation or mitigation mechanisms.

  • Hardware costs, cost of labour, favourable cost of capital, low taxes and low, but positive, profit margins all contributed to lowering the price of utility solar power in the Middle East. These prices and policies can be replicated elsewhere without direct subsidies and prices will continue to reduce in the future.
