China is transitioning from a focus on adding renewable capacity to building a "new electricity system" that integrates high levels of variable energy. In 2024, China invested $625 billion USD in clean energy, significantly outpacing other major regions. This shift, combined with expanding electrification in industry, transport, and buildings, is contributing to a structural decline in fossil fuel generation. By the first half of 2025, combined wind and solar generation surpassed the combined output of hydro, nuclear, and bioenergy, and total installed capacity for these sources exceeded that of coal for the first time.

China's massive scale in producing solar, wind, batteries, and electric vehicles has significantly lowered global costs, with solar module prices falling over 70% between 2022 and mid-2025. This manufacturing capacity allows China to potentially supply the entire world's solar needs for 2030 as defined by the IEA. These affordable technologies are facilitating an 'energy leapfrog' in emerging markets across Africa, Asia, and Latin America, where some countries now have higher solar shares in power generation than the US. Consequently, China's own fossil fuel demand is approaching a plateau, and the global demand for fossil fuels is projected to be in structural decline by 2030.

The EU is seeing growth in cleantech manufacturing and solar capacity, but the overall pace of transition remains insufficient. Significant financing gaps, fossil fuel dependencies, and misaligned agricultural policies continue to obstruct the path to climate neutrality.

The policy brief examines the misalignment between legacy gas utility energy efficiency programs and current state climate goals in the United States. It highlights how traditional cost-effectiveness tests often prioritize short-term gas appliance rebates over high-impact weatherization and electrification. Using examples from states like New York and Massachusetts, the document proposes six strategic reforms to redirect ratepayer funding toward long-term decarbonization and building efficiency.

The document examines the practice of gas line extension allowances, where the cost of connecting new buildings to the natural gas system is funded through the bills of existing customers. It argues that this model is failing as customers shift toward electric alternatives, creating a financial risk of stranded investments. Eight US states have already taken action to reduce or phase out these subsidies, which RMI estimates could save up to $750 million in annual utility costs across those states. Evidence from California and Colorado suggests that removing these subsidies encourages developers to choose all-electric options over gas.

Buildings account for 18% of Canada's GHG emissions, with residential space heating as the primary energy driver. The document argues that deep energy retrofits (DERs)—defined as achieving a minimum 50% reduction in energy consumption—are essential for net-zero targets. While high upfront costs are a barrier, the green building industry could contribute CAD 150 billion to the economy by 2030, with annual energy bill savings estimated at CAD 10.8 billion. The brief recommends adopting the highest tier of the National Building Code, implementing innovative financing like Property Assessed Clean Energy (PACE), and scaling prefabricated retrofit models like Energiesprong.

A research analysis by World Weather Attribution finds that human-induced climate change made a July 2025 heatwave in Norway, Sweden, and Finland approximately 2°C hotter and at least ten times more likely than in a preindustrial climate. The event caused significant strain on healthcare systems, disrupted reindeer grazing and Sámi livelihoods, and led to increased drowning deaths and wildfires. The report highlights that current winter-focused building designs in the Nordic region are inadequate for rising temperatures and that similar heatwaves are now twice as likely as they were during the previous major event in 2018 due to a global warming increase from 1.1°C to 1.3°C.

The document examines the intersection of climate change, housing quality, and health in Toronto, proposing that an equity-focused Building Emissions Performance Standards (BEPS) policy can mitigate health risks for marginalized communities. It highlights how retrofits—such as switching from gas to electric heating and stoves, improving insulation, and adding mechanical ventilation—can reduce asthma risks, protect against extreme temperature events, and lower outdoor air pollution. The brief warns against the risks of tenant displacement and 'renovictions' and recommends strong tenant protections, the creation of Community Accountability Boards, and the integration of health metrics into BEPS monitoring to ensure benefits are shared equitably.

The building sector accounts for 18% of Canada's GHG emissions, necessitating a focus on upgrading approximately 11 million existing residential buildings. Achieving net-zero requires a balance of deep energy retrofits (DERs), fuel-switching to heat pumps, and expanding clean electricity. An annual investment of CAD 10-15 billion until 2040 could generate 200,000 jobs and CAD 48 billion in economic development. The document recommends strengthening building codes, implementing PACE financing, and integrating energy efficiency with affordable housing policies.

The report evaluates renewable energy options for a municipal water station in Ukraine serving 400,000 residents. It compares 100% decentralised systems (PV+Battery vs. Wind+Battery) and feasible grid-connected hybrid systems, finding that while wind is more cost-effective, solar PV is the only viable on-site installation due to space constraints. For heating, water-to-water heat pumps are identified as the optimal solution. The report also maps international financing opportunities from institutions like the EBRD, EIB, and World Bank to support implementation.

The document argues that the current NECP process suffers from incomplete Member State reporting, outdated reporting categories, and poor data accessibility. It recommends that the European Commission enforce full reporting through 2050, expand the reporting template to include electrification rates, energy storage, demand-side flexibility, and grid planning, and mandate digital submissions to create a single, publicly available data source.

The author outlines three priorities for Canada's post-election climate strategy: improving affordability through energy-efficient technologies like heat pumps, maintaining economic competitiveness against global decarbonization trends and carbon border tariffs, and protecting communities from the increasing financial and health costs of extreme weather disasters.

The Canadian Climate Institute outlines three priorities for Canada's climate strategy: improving affordability through clean energy technologies, enhancing economic competitiveness via industrial carbon pricing to align with global partners, and increasing protection against escalating climate-driven financial losses from natural disasters.

Analysis of NOAA data shows that all 50 U.S. states and 99% of 242 analyzed cities have warmed since 1970. Alaska was the fastest-warming state (+4.3°F), while Reno, Nevada, saw the highest city-level increase (+7.8°F). The contiguous U.S. has warmed by approximately 2.8°F, exceeding the global warming limit of 2.7°F (1.5°C). The document advocates for a clean energy transition through zero-emission vehicles, solar and wind power, and heat pumps to mitigate these trends.

The document assesses three types of multifunction mechanical systems designed to reduce the cost and disruption of building decarbonization retrofits in multifamily housing. It examines fully packaged systems (e.g., Systemair Genius), partially packaged systems (e.g., Villara AquaThermAire), and distributed systems (e.g., Ephoca AIO WM paired with SanCO2), focusing on their ability to integrate heating, cooling, ventilation, and domestic hot water (DHW) using low global warming potential refrigerants.

The report highlights solar power as the primary engine of the global energy transition, noting it surpassed 2,000 TWh of generation in 2024 and doubles every three years. While emerging drivers such as data centres, EVs, and heat pumps have structurally increased electricity demand, clean generation is projected to grow fast enough to meet this demand and drive a structural decline in fossil fuels by 2030. Central to this shift is the progress in China and India, where clean power deployment is breaking the historical link between economic growth and fossil fuel expansion, potentially tipping the global balance toward a decline in fossil generation.

In 2024, clean power reached a milestone of 40.9% of global electricity generation, driven by a record surge in solar and a rebound in hydropower. Despite this growth, global power sector emissions reached a record high of 14.6 billion tonnes of CO2 because extreme heatwaves drove a 4.0% increase in electricity demand, forcing a 1.4% rise in fossil fuel generation to meet the additional cooling needs.

In 2024, global electricity demand rose by 4% to 30,856 TWh, driven largely by China and extreme heatwaves. Low-carbon sources reached a historic high of 40.9% of global generation, with solar and wind combined surpassing hydropower. Despite this, global power sector emissions hit a record high, increasing by 1.6% due to a rise in fossil generation linked to cooling demand during heatwaves.

In 2024, clean power surpassed 40% of global electricity generation for the first time since the 1940s, driven by record solar growth. Despite this, global power sector emissions reached an all-time high of 14.6 billion tonnes of CO2 because heatwaves drove a 1.4% increase in fossil generation to meet cooling demand. Solar generation doubled over the last three years, reaching 2,131 TWh, while emerging drivers like AI data centres, EVs, and heat pumps structurally increased demand growth. China and India are increasingly decoupling their electricity demand growth from fossil fuel expansion, with China's clean generation meeting 81% of its demand increase in 2024.

In 2024, low-carbon electricity generation exceeded 40% of the global total for the first time in decades, driven by unprecedented solar energy growth. Despite this, extreme heatwaves increased electricity demand for cooling, leading to a slight rise in fossil fuel generation and record-high sector emissions. Solar energy has doubled its generation over the last three years, with China contributing over half of the 2024 increase. The report concludes that while short-term weather fluctuations can cause temporary fossil fuel spikes, the long-term trend is dominated by clean energy growth and electrification.
