The report critiques the Indonesian government's strategy of using natural gas as a 'bridge' fuel, specifically focusing on planned gas infrastructure in Bali, including a Floating Storage Regasification Unit (FSRU) and several gas power plants (PLTG). It argues that gas is not a clean energy source due to methane leaks and carbon emissions, which contribute to the extreme weather and water crises already affecting Bali. The document highlights social and environmental damages from existing gas projects, such as the PLTGU Pemaron, and argues that Bali's significant renewable energy potential—estimated up to 26 GW—should be prioritized over fossil fuels to achieve true energy independence and climate resilience.

The report argues that MDBs fail to deliver genuine climate finance due to flawed accounting methodologies that allow fossil fuel-related projects, such as liquefied natural gas (LNG) and waste-to-energy incineration, to be counted as climate action. It highlights a systemic bias toward mitigation over adaptation and a preference for loans over grants, which exacerbates debt in the Global South. Specific analysis of the AIIB and ADB reveals transparency gaps, the inclusion of high-emitting projects in climate portfolios, and a failure to integrate gender equality and human rights into climate finance principles.

The Union of Concerned Scientists developed the Climate 2030 Blueprint using a modified version of the National Energy Modeling System (UCS-NEMS) to evaluate a 'Blueprint case' against a 'Reference case'. The Blueprint case centers on a cap-and-trade program starting in 2011, designed to reduce U.S. emissions to 26 percent below 2005 levels by 2020 and 56 percent below 2005 levels by 2030. This cap is supported by complementary policies in energy efficiency, electricity generation, and transportation to lower the overall cost of compliance. The analysis incorporates supplemental data on building and industrial efficiency from the American Council for an Energy-Efficient Economy and biomass supply curves from the University of Tennessee and Oak Ridge National Laboratory.

The report argues that the United States can significantly reduce its reliance on fossil fuels by deploying a diverse mix of renewable energy sources, which have the technical potential to meet current electricity needs many times over. It highlights wind, solar, geothermal, bioenergy, and hydropower as key resources, noting that wind and geothermal are already competitive with new coal and natural gas plants in some cases. The document identifies critical barriers to this transition, including the need for a modernized transmission grid, streamlined siting processes, and sustainable biomass harvesting. It proposes a policy package featuring a national renewable electricity standard (RES) ramping up to 40% by 2030, extended tax credits, and increased R&D funding. While discussing carbon capture and storage (CCS) and advanced nuclear power as potential low-carbon supplements, the report notes significant cost uncertainties, infrastructure requirements, and safety risks associated with these technologies.

The document argues that the costs of failing to reduce carbon emissions in the United States are prohibitive, citing projected damages to coastal infrastructure, public health, water resources, agriculture, transportation, and energy systems. It highlights that under high-emissions scenarios, the annual economic impact could reach 1.9 percent of GDP by 2100. Specific regional risks include severe sea-level rise in Florida and the Northeast, extreme heat waves in Midwestern cities, water scarcity in the Southwest, and increased wildfire frequency in the West Coast and Rocky Mountain regions. The document advocates for a reduction of carbon emissions by at least 80 percent from 2005 levels by 2050 to avoid the worst consequences.

The U.S. electricity system relies heavily on freshwater, with cooling power plants accounting for 41 percent of all freshwater withdrawals. This dependence creates a 'collision' where energy production competes with municipal, agricultural, and ecosystem needs, a situation exacerbated by global warming. The report details regional risks—such as hydropower instability in the Northwest and cooling water shortages in the Southeast—and highlights low-water alternatives like wind, solar photovoltaic, and dry-cooling systems.

The Union of Concerned Scientists finds that increasing Wisconsin's renewable electricity standard to 25% by 2025 is achievable and affordable. Under the most likely 'No Hydro Imports' scenario, the state would see a $59 million reduction in electricity bills (when accounting for carbon savings), the creation of 2,650 new jobs, and a reduction in CO2 emissions equivalent to removing 2.1 million cars from the road. The analysis highlights Wisconsin's significant technical potential in wind, solar, and biomass to meet these targets while reducing reliance on imported fossil fuels.

The analysis finds that most energy supply investments by the World Bank, IFC, and ADB are either aligned with or could be aligned with 2°C pathways under specific conditions. Electricity transmission and distribution (T&D) represent the largest share of financing for the World Bank and ADB, accounting for approximately half of the volume of financing and 40 percent of projects. While renewables projects outnumbered natural gas power generation projects in both number and finance volume, the report warns that natural gas must act as a true 'bridge' by displacing coal rather than adding to it. The study identified 21 oil and gas production projects as 'controversial' due to high emissions and lock-in risk. Misaligned projects often cited strong development rationales, but the authors argue that the urgency of climate change requires transformational rather than incremental improvements. The report recommends that MDBs improve disclosure of indirect financing, shift toward newer technologies like battery storage, and ensure fossil fuel production support is reviewed against G7 commitments to phase out inefficient subsidies by 2025.

Dr. Jonathan Pershing of the World Resources Institute argues that energy security and climate goals are often aligned but require an integrated policy framework to avoid conflicts. He proposes effectiveness and political feasibility criteria to evaluate policies, noting that while efficiency and renewables offer 'double wins,' other options like natural gas imports or corn-based biofuels can create security risks or environmental damage. The testimony provides specific policy recommendations for the US regarding cap-and-trade, production tax credits, transportation, and biofuels, while also highlighting the vulnerability of developing nations and the risk of climate-induced conflict and migration.

The paper presents a new methodology using machine learning and climate science to assess physical climate risks for power generation portfolios. Pilot testing on the EBRD's thermal and hydro assets indicates that annual generation losses could increase from 0.76 TWh (0.4%) in the baseline period to 7.0 TWh (3.3%) under RCP4.5 and 7.4 TWh (3.5%) under RCP8.5 by 2030. The analysis identifies water stress and rising water temperatures as the primary drivers of loss for thermal assets, while hydro assets are primarily affected by reduced precipitation and upstream water consumption. The study further finds that combined cycle gas turbine (CCGT) plants are more resilient than coal-fired plants, and that once-through cooling systems are the most vulnerable cooling technology.

The document presents the Energy Access Explorer (EAE), a digital public good providing over 70 datasets for Tanzania, including a collaborative database of 135 mini-grids. It highlights the platform's ability to perform multi-criteria analysis (MCA) to identify market expansion opportunities and prioritize energy access in rural areas, where connectivity is only 11%. The report notes that solar PV and hydropower dominate the mini-grid landscape, and that the market has become more favorable following a 2021 policy shift allowing cost-reflective tariffs negotiated with EWURA.

The report reviews MDB loan documentation from 2006–2008, finding that only a small number of projects comprehensively addressed the policy, regulatory, and institutional elements necessary for sustainable energy. It argues that standard energy policies often prioritize short-term costs over long-term environmental benefits and recommends that MDBs more consistently integrate greenhouse gas emission considerations, energy efficiency, and poverty alleviation into their electricity sector support.

The document describes a methodology for estimating annual electricity generation of power plants when plant-level data are unavailable. The approach utilizes statistical regression and machine learning, incorporating plant-level characteristics (size and fuel type) and country-level data (average generation per megawatt of installed capacity). The author notes that fuel-specific models increase accuracy for wind, solar, and hydropower plants, while natural gas plant estimations show improvement but maintain high error rates, particularly for smaller facilities.

The WRI Water Program in Ethiopia focuses on three strategic areas: analyzing water risk through modeling and mapping, promoting healthy watersheds via nature-based solutions, and enhancing urban water resilience in cities like Addis Ababa and Dire Dawa. The program collaborates with Ethiopian government entities, including the Ministry of Water, Irrigation and Energy, to integrate water and climate constraints into national development planning and to protect ecosystems that secure long-term water supplies.

The document details Rwanda's 2004 electricity crisis, caused by declining water levels in Lake Bulera due to watershed degradation and poor maintenance of the Ntaruka hydropower station. In response, the government implemented strict land-use policies, including banning agricultural activities in the Rugezi Wetlands, and launched ecosystem restoration projects. These efforts restored the Ntaruka plant to full capacity by October 2007 and prompted Rwanda to diversify its energy portfolio into methane, geothermal, and solar power to increase climate resilience.

Tanzania has expanded its mini-grid capacity since 2008 through the small power producers (SPP) framework, now operating over 100 systems serving approximately 184,000 customers. While hydro is the most common technology, fossil fuel systems provide the majority of customer connections. The government has updated regulatory frameworks to better support solar and wind energy and attract private investment, including pegging tariffs to the U.S. dollar and lowering project size eligibility to 100 kW. However, challenges remain regarding cumbersome non-energy regulatory clearances, limited access to local commercial bank financing for domestic developers, and a lack of systematic data on socioeconomic impacts.

Free-flowing rivers, defined as those largely unaffected by human-made changes to flow and connectivity, are critical for biodiversity, groundwater recharge, and human survival. Only one-third of the world's 246 longest rivers (those 1,000 km or longer) remain free-flowing, with most remaining in remote, less developed, or politically complex regions. Infrastructure, particularly dams, roads, and buildings, disrupts sediment transfer and animal migration, threatening deltas and fish stocks. WWF aims to protect these systems by opposing harmful dams, promoting protective laws, supporting sustainable energy alternatives to hydropower, and pursuing dam removal.

Ecological connectivity allows animals to move freely to find food and breed, sustaining natural processes that provide clean air, soil, and water. Human activities—including infrastructure development, deforestation, and overfishing—fragment these habitats, leading to human-wildlife conflict and ecosystem breakdown. Climate change further necessitates connectivity as species must move to adapt to shifting environments. WWF implements restoration strategies such as wildlife corridors and sustainable land-use planning, exemplified by projects in Borneo, Southern Africa, the Mekong region, and the Terai Arc. To scale these efforts, WWF co-created the Wildlife Connect initiative with the Center for Large Landscape Conservation and the IUCN WCPA.

The Amazon is the world's largest rainforest and river system, containing one in 10 known species on Earth and storing between 90 billion and 140 billion metric tons of carbon. It is currently threatened by deforestation driven by cattle ranching, soy farming, and infrastructure, as well as climate change, which has caused rainfall to decline across 69% of the forest since 2000. WWF is implementing conservation strategies such as the Amazon Region Protected Areas program in Brazil to maintain a network of 120 protected areas.

The document describes the global decline of free-flowing rivers due to fragmentation from dams, roads, and dikes, which threatens biodiversity and human livelihoods. It highlights the creation of a scientific inventory of the world's last free-flowing rivers and provides case studies of conservation successes and ongoing threats in Mexico, Colombia, Slovenia, Zambia, Brazil, and Myanmar.
