# Patch Notes #008: Climate / Energy Transition Evidence Matrix

Version: v0.1 public pre-memo matrix
Date: 2026-07-03
Status: Source-anchor matrix for reviewer critique. This is not a final evidence review.

## Working Standard

Every claim should identify the sector and constraint: power, transportation, buildings, industry, agriculture, transmission, permitting, reliability, affordability, workforce, supply chain, or local siting. "Clean energy" is not a complete policy mechanism.

| Claim | Evidence Strength | Initial Source Anchor | Reviewer Ask |
| --- | --- | --- | --- |
| U.S. emissions come from multiple sectors, so electricity policy alone cannot solve climate risk. | Strong | EPA Greenhouse Gas Inventory | Which sector chart should lead? |
| Electrification can reduce emissions, but it increases the importance of grid capacity, reliability, transmission, and generation buildout. | Strong directionally; needs scenario detail | EIA, DOE, NREL, grid operator forecasts | Where are demand-growth claims strongest? |
| Transmission and interconnection constraints are major bottlenecks for clean-energy deployment. | Strong directionally; regional variation | DOE transmission studies, FERC Order 1920, LBNL interconnection data | Which reforms are most practical? |
| Reliability and affordability are political constraints as well as engineering constraints. | Strong as design principle; metrics vary | NERC reliability assessments, EIA price data, state utility data | How should cost be discussed without stalling decarbonization? |
| Permitting and local opposition can slow clean infrastructure, fossil infrastructure, transmission, mining, and industrial projects. | Strong directionally | CEQ/NEPA materials, DOE permitting, local siting research | Which timeline claims are real and which reforms help? |
| Industrial decarbonization is harder than power-sector decarbonization and needs technology, infrastructure, and market design. | Moderate/strong | DOE industrial decarbonization roadmap, IEA | Which constraints bind first? |
| Critical minerals and clean-energy supply chains create new dependencies, environmental harms, and industrial-policy questions. | Strong directionally | DOE critical materials, IEA, USGS | Where are claims overblown? |
| Fossil-fuel workers and communities need credible transition plans, not slogans. | Strong as political/economic principle; evidence varies | DOE, BLS, regional transition research | What has actually worked? |
| A durable transition must reduce emissions while maintaining reliability, affordability, local legitimacy, and industrial capacity. | Synthesis hypothesis | Cross-source synthesis | Where does this frame hide hard tradeoffs? |

## Research Gaps Before Memo v0.2

1. Current U.S. emissions by sector and trend.
2. Electricity demand growth from data centers, electrification, manufacturing, and population.
3. Transmission/interconnection queue size and regional bottlenecks.
4. Reliability risks by region and resource mix.
5. Rate impacts and household energy burden.
6. Permitting timelines for transmission, renewables, nuclear, mining, pipelines, and industrial projects.
7. Industrial decarbonization pathways for steel, cement, chemicals, and heavy transport.
8. Worker/community transition evidence from coal, oil, gas, and manufacturing regions.
