In the first half of 2025, record-breaking solar generation in Great Britain offset lower-than-average wind speeds, limiting the increase of gas power. Solar generation rose by 32% to 9.91 TWh, with a peak grid level of 14 GW on 8 July. Analysis shows that low-wind and low-solar days coincide only 2% of the time, demonstrating a natural balance in the British climate. While gas generation increased overall in H1 2025 to compensate for lower power imports, it fell to 21% of electricity generation in June. The report advocates for doubling energy storage capacity by 2030 and transitioning gas and biomass plants to a strategic reserve by the early 2030s to further reduce costs and emissions.

The report identifies a significant 'take-off' in solar panel imports to Africa, with imports from China rising 60% to 15,032 MW in the 12 months to June 2025. This growth is widespread, with 20 countries setting new import records and 25 countries importing at least 100 MW. The report suggests this surge may be driven by distributed solar, potentially replacing expensive diesel generation and significantly increasing electricity supply in several countries, such as Sierra Leone and Chad.

BRICS nations now generate over half of the world's solar power, driven primarily by China, India, and Brazil. In 2024, these countries accounted for 51% of global solar electricity generation, with China alone contributing 39%. Solar power met 37% of the total increase in electricity generation across BRICS members in 2024, contributing to a total clean energy share of 70% for new generation growth. While China, India, and Brazil show strong continued growth in 2025, other members like Russia, Indonesia, and Egypt lag in solar deployment or remain dependent on fossil fuels.

The BRICS bloc generated over half of the world's electricity in 2024, with China dominating renewable energy production. While solar and wind capacity have grown exponentially in China, India, and Brazil since 2015, progress has stalled in Russia and South Africa. Hydropower's share of BRICS renewable generation fell from 82% in 2015 to 45% in 2023 as solar and wind expanded. China leads the bloc in total renewable energy jobs, though Brazil has the highest proportion of such jobs relative to its population.

The EU aims for a 66% share of renewables in electricity generation by 2030, requiring significant increases in wind and solar capacity. While solar deployment is outpacing expectations, wind power faces challenges from grid bottlenecks and permitting issues.

In 2024, global electricity generation reached new record highs for solar, wind, hydro, gas, and coal. Solar was the fastest-growing source, increasing by 474 TWh to reach a 6.9% share of the global mix, with China contributing 53% of this growth. Wind generation also hit a record of 2,494 TWh, though growth slowed due to weather conditions. Hydro rebounded to an all-time high of 4,416 TWh following 2023 droughts, largely driven by China. Nuclear generation grew by 2.5% to 2,768 TWh, but its global market share fell to a 45-year low of 9%. Gas and coal both reached record generation levels in 2024, though their shares of the global electricity mix declined to 22% and 34% respectively, as electricity demand grew faster than their production.

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.

The U.S. generated a record 756,621 GWh of electricity from solar and wind in 2024, accounting for 17% of total generation. Solar is the fastest-growing source, increasing 7.8-fold over the last decade, while wind grew 2.4-fold. Combined solar and wind generation has surpassed coal, which dropped to 15% of the electricity mix in 2024.

Batteries are scaling up rapidly in the US, supporting record solar growth and reducing reliance on gas and coal. In 2024, California and Nevada became the first states to exceed a 30% annual solar share. California's battery capacity grew nearly twentyfold between 2020 and 2024, allowing batteries to become the largest electricity source during evening hours in April 2024. Texas also saw significant growth, installing 3.9 GW of utility-scale battery capacity in 2024. Nationally, the US added 36 GW of new solar capacity in 2024, with 10 GW of utility-scale batteries added, reflecting a trend toward co-located solar-plus-battery projects.

In 2024, wind and solar produced 17% of US electricity, overtaking coal for the first time as coal fell to 15%. This transition is evident in 24 states, driven by market dynamics, cost-effectiveness, and policy mandates like the Climate and Equitable Jobs Act in Illinois.

Ember modelling indicates that the UK can reduce biomass power generation by 55% to just 2% of total electricity generation by 2030 without compromising grid stability. This low-biomass pathway involves reducing biomass capacity by 2 GW—retaining only the equivalent of one unit at Drax—and replacing the lost generation primarily through increased power imports (6.9 TWh) and a slight increase in gas use (2.9 TWh). The report highlights that biomass power is significantly more expensive than gas or wind, costing £138/MWh under a Contract for Difference, and poses energy security risks due to its total reliance on imports, as Drax consumed 5.8 million tonnes of non-UK wood biomass in 2023. Despite the reduction in biomass, the UK would remain a net exporter of electricity, totaling 60 TWh annually.

The document details how human activities, primarily the burning of fossil fuels, have increased atmospheric concentrations of carbon dioxide, methane, and nitrous oxide to levels higher than any point in the last 800,000 years. These gases have caused a combined 1.6°C of global warming since 1850, with CO2 and methane accounting for 95% of this increase. In the United States, 76% of greenhouse gas emissions originate from three sectors: transportation (28%), electric power (25%), and industry (23%). The text emphasizes that while the U.S. has reduced emissions to approximately 17% below 2005 levels, the pace of reduction must more than triple to meet 2030 national targets.

The document outlines the technical framework for the State of Climate Action series, focusing on tracking global greenhouse gas emission reductions and carbon removal. It details the process of translating sectoral transformations into actionable targets and the categorization of progress (e.g., 'on track' or 'off track'). The 2024 update introduces 2035 targets for 16 indicators, a new indicator for wind and solar power in electricity generation, and revised transport sector targets based on recent modeling.

The report finds that Alberta can almost completely decarbonize its electricity generation within the next decade using wind, solar, and gas with carbon capture. While federal Clean Electricity Regulations are a point of political contention, modelling suggests they have little impact on the long-term supply mix compared to the massive projected growth in electricity demand driven by industrial electrification. The transition's success depends on scaling up transmission infrastructure and maintaining policy stability to attract private investment.

In the first half of 2024, wind and solar power generated 30% of the EU's electricity, surpassing fossil fuels (27%) for the first time. This transition occurred despite a 0.7% increase in electricity demand. Fossil fuel generation fell by 17%, with coal dropping by 24% and gas by 14%. Renewables overall provided 50% of the EU's electricity, aided by a 21% rebound in hydro generation. Power sector emissions decreased by 17% compared to the same period in 2023, and are 31% lower than in the first half of 2022. While capacity additions are high, the report notes a gap between national ambitions and the EU's 2030 targets under the REPowerEU plan, particularly for wind energy.

In 2023, solar and wind power continued to grow, with solar producing a record 5.5% of global electricity and wind reaching 7.8%. China was the primary driver for both, accounting for 51% of solar growth and 60% of wind additions. Conversely, coal generation reached a record high of 10,434 TWh (35% of the global mix), largely due to droughts in China reducing hydropower output, which fell by a record 88 TWh. Fossil gas remained the second-largest source at 23%, with growth driven by the US. Nuclear generation saw a slight rebound to 9.1% of the mix, while bioenergy reached a record 697 TWh (2.4%). The report notes that while solar and wind are on a positive trajectory, coal and gas must decline sharply, and nuclear and hydro must accelerate growth to meet IEA Net Zero Emissions targets by 2030.

The guide argues against one-size-fits-all climate action lists, instead encouraging individuals to audit their own habits in four key areas: diet, electricity use, travel, and home temperature regulation. It highlights the environmental impact of agriculture, fossil-fuel electricity, and transportation, offering specific practical steps—such as shifting to plant-rich diets, upgrading to LED bulbs, and reducing air travel—to lower personal greenhouse gas emissions.

The analysis finds that while gas-fired power plants emit 58% less CO2 at the stack than coal, the lifecycle benefit is reduced to 24% when considering upstream emissions. This benefit varies wildly by production basin; gas from northeast Pennsylvania can significantly reduce GHG impacts, while gas from the Permian basin could potentially worsen them by 20% compared to coal. The report concludes that for natural gas to be compatible with net-zero goals, both aggressive upstream methane abatement and downstream carbon capture and storage (CCS) are required, noting that abated coal with CCS actually shows 37% lower emissions than abated gas with CCS due to the latter's persistent upstream methane and liquefaction emissions.

The Electrical Utilities Criteria provide a framework for certifying entities and debt instruments based on their emission intensity and transition pathways. It defines specific thresholds for existing and new capacity across various technologies, including fossil fuels and renewables, while integrating cross-cutting requirements for carbon capture, hydrogen, and bioenergy. The criteria also mandate adaptation and resilience risk assessments to ensure long-term operational viability under climate change.

The report establishes a framework for certifying electrical utilities and their debt instruments based on their alignment with a 1.5-degree warming scenario. It defines a global emission intensity transition pathway based on IEA Net Zero (NZE) 2023 data, requiring utilities to reduce carbon intensity from 460 gCO2/kWh in 2025 to 0 by 2050. The criteria distinguish between existing capacity, which may be retrofitted with carbon capture or low-carbon co-firing, and new capacity, for which no new fossil fuel investments are eligible. It also sets specific non-combustion emission thresholds for hydropower, geothermal, and bioenergy, and incorporates EU Taxonomy standards for CO2 transport and methane leakages.
