From fossil flows to renewable cooperation - tripling renewables in the Med
The Mediterranean region's renewable power capacity is projected to double from 315 GW in 2023 to 626 GW by 2030, primarily driven by solar and wind. However, this trajectory falls 374 GW short of the TeraMed Initiative's 1 TW goal. To bridge this gap, the region would need to install an additional 54 GW of wind and solar annually beyond current plans, totaling 98 GW per year, which significantly exceeds the historical maximum annual deployment of 45 GW.

RE-powering India’s heavy industries: 20 GW today, 24/7 tomorrow
India's heavy industries—steel, cement, and aluminium—have a 20 GW profitable opportunity to integrate solar power today through green energy open access, potentially reducing annual emissions by 29 million tonnes. While sourcing 50% renewable energy (RE) is currently cost-effective without storage, achieving 24/7 RE is prohibitively expensive, costing up to 3.5 times the price of standard RE generation due to the massive battery storage and capacity oversizing required. The report highlights that steel offers the most immediate cost-saving potential, whereas aluminium remains heavily reliant on captive coal power, requiring stronger regulatory mandates to transition.

تقرير المراجعة العالمية للكهرباء لعام 2025
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.

Accounting shift drives emissions reduction
The report examines the impact of transitioning from state-based average emissions factors (Method 1) to site-specific estimates (Method 2) for fugitive methane emissions in Australian open-cut coal mines. It finds that this accounting shift has consistently decreased reported emissions by 65–70% according to Reputex, with a particularly stark effect in New South Wales, where reported fugitive emissions intensity is six times lower than the state-based factor.

Shift to open-cut Coal Mining and impact on emissions estimate
Australia's coal industry has seen a rapid expansion of open-cut mining, which grew by 224% between 1990 and 2022 and now accounts for over 85% of total production. This shift has led to a decrease in reported emissions intensity because open-cut mines rely on gas models from 1991 for estimates rather than direct measurement. Consequently, reported fugitive emissions from surface mines have grown at a significantly slower rate than production; for example, since 2005, production increased by 45% while fugitive emissions only rose by 13%.

Australia’s coal mining emissions paradox
Australia's coal industry reports a record low in fugitive emissions despite a 170% increase in production from 1990 to 2022. This paradox is attributed to the closure of gassier underground mines and a shift toward non-verified, site-specific estimation methods for open-cut mining, which may mask the true scale of emissions.

Rising Coal Production, Falling Emissions
Australia's reported fugitive emissions from coal mining have decreased by over 20% since 2005, despite raw coal production increasing by 170% between 1990 and 2022. While some reductions are attributed to mitigation investments, such as VAM-to-power projects and pre-mine drainage, the report argues that the trend is largely driven by a shift toward open-cut mining, the closure of high-emitting underground mines, and changes in emissions accounting methods.

Underground coal mine closures - a historic win, but future risk
Underground coal mine closures have been the primary driver of fugitive emissions reductions in Australia's coal sector, as a small number of 'super-emitting' mines contribute a disproportionate share of total emissions. While strategic investments in methane capture have helped, most reductions resulted from the closure of older mines or safety-related shutdowns. However, the document warns that 27 proposed projects and recent license extensions, such as for the Narrabri mine, threaten to undermine national and state climate targets.

The final push for EU Russian gas phase-out
The report finds that EU imports of Russian gas increased by 18% in 2024, despite a goal to phase them out by 2027. It highlights a significant misalignment between gas infrastructure expansion and stagnating demand, predicting that supply capacity will exceed demand by 131 bcm by 2030. The document argues that the EU is replacing one fossil fuel dependency with another via LNG, which exposes the region to price volatility and high emissions. It recommends legally binding phase-out targets, reduced gas demand across all sectors, and more efficient use of existing infrastructure to ensure energy security and climate alignment.

Australia’s coal mining emissions paradox
Australia's coal production grew by 170% between 1990 and 2022, yet fugitive emissions increased by only 0.17%. This trend is driven by the closure of high-emitting underground mines and a transition toward open-cut mining, which relies on estimated rather than measured emissions. The report highlights a concerning shift toward site-specific emissions reporting (Method 2), which has significantly lowered reported emissions in New South Wales compared to state-based averages. While underground mine closures have provided historic emissions wins, new project expansions and extensions threaten to reverse these gains.

El factor geográfico: cómo las condiciones ambientales determinan el control del metano desde el espacio
The report examines the 'geography factor' in satellite methane monitoring, identifying that approximately 30% of global coal, oil, and gas infrastructure is located in regions where environmental conditions hinder data collection. It details how factors like persistent tropical cloud cover, low winter sunlight in high latitudes, and mountainous terrain create 'difficult' observation zones. The authors argue for a multi-tiered observation system that integrates satellites with aircraft, drones, and ground-based sensors to overcome these geographic limitations and support the Global Methane Pledge's goal of reducing emissions by 30% by 2030.

Powering through the heat: how 2024 heatwaves reshaped electricity demand
In 2024, extreme heatwaves in China, the US, and India drove record air conditioning use, significantly increasing electricity demand and forcing a surge in coal and gas generation to meet the shortfall. The report highlights that cooling demand accounted for 37% of the US demand increase (April-September), 31% in China, and 19% in India for the same period. In China, coal generation grew by 10% in September 2024, while in the US, coal rose by 6.4% in June. The authors argue that relying on fossil fuels to meet cooling needs creates a feedback loop that accelerates climate change, recommending a transition to energy-efficient ACs, rooftop solar, and improved retail pricing to enhance grid resilience.
