The report analyzes the energy strategy of the Three Seas Initiative (3SI) countries, finding that planned LNG and pipeline capacity will significantly exceed projected gas demand by 2030. It warns that this creates a risk of stranded assets and security vulnerabilities due to global price volatility. The author advocates for shifting investment from gas infrastructure to wind, solar, and grid interconnectors, noting that 3SI countries could reach a 67% renewable electricity share by 2030.

The report argues that the US can achieve a 98% reduction in transportation CO2 emissions by 2050 through a combination of rapid vehicle electrification, improved energy efficiency, and the use of low-carbon liquid fuels for hard-to-decarbonize sectors. It presents a 'Core' scenario where all new light-duty vehicles are zero-emission by 2035 and medium- and heavy-duty vehicles by 2040. The analysis emphasizes that while technological shifts are necessary, a truly equitable transition requires behavioral changes to reduce overall energy demand, such as increased use of public transit and active transportation. The report concludes that these pathways are economically viable, with net costs of less than 1% of GDP, and would yield significant public health and climate benefits.

The Union of Concerned Scientists used the HOMER Grid model to analyze microgrid configurations for Parker Village, a planned eight-acre development in Highland Park, Michigan. The analysis focused on a grid-separated (islanded) system powered by solar photovoltaic panels and battery storage to maximize community independence. Findings indicate that while a grid-separated microgrid is feasible, it requires significant solar and battery capacity and necessitates fossil fuel backup (natural gas or diesel) to meet winter peak demand. Alternatively, a grid-connected backup option reduces initial investment costs and battery requirements but maintains a dependency on the utility for approximately 2% of annual power demand. The study emphasizes that increasing building energy efficiency could reduce the necessary scale of energy resources and minimize reliance on fossil fuel backups.

The document details a bottom-up modeling exercise using the Energy Scope tool to project Colombia's energy transition. It outlines a path toward net-zero emissions by 2050, characterized by a massive scale-up of solar and wind capacity, the gradual phase-out of fossil fuels, and the integration of energy storage and green hydrogen. The modeling identifies specific capacity targets for renewable energy across three time horizons and highlights the role of natural gas as a transitional fuel for transport and industry before full electrification.
