Clean Energy Graveyard (C.E.G)

An interactive map and analysis tool tracking cancelled renewable energy projects across the UK. Built using the government's Renewable Energy Planning Database (REPD), it visualises refused and withdrawn planning applications alongside AI-generated analysis of community opposition patterns.

What It Does

• Interactive Map -- Browse 156+ cancelled renewable energy projects (solar, wind, battery storage) plotted on a MapLibre GL map of the UK
• NIMBY Analysis -- AI-generated scoring of community opposition levels, with confidence ratings, sourced news articles, and tongue-in-cheek commentary
• Filtering -- Filter projects by technology type (Solar, Wind, Battery, Other) and date range (2020-2025)
• Local Authority Layers -- View local authority boundaries colour-coded by project density, with click-to-zoom
• Project Details -- Click any project to see capacity, planning references, links to council planning portals, and related news articles
• Delay Visualisation -- Charts showing average time before project cancellation

python main.py

Data Sources

File	Description
points.geojson	Cancelled renewable project locations and metadata
nimby_score.json	AI-generated opposition analysis per project
councils.json	Planning authority name to planning portal URL mapping
localauth.json	Local authority boundary geometries (GeoJSON)
final.json	Aggregated statistics
df_refused.json	Refused project timing data
df_withdrawn.json	Withdrawn project timing data

The upstream data comes from the UK Government's REPD quarterly extract, filtered to projects with status "Planning Permission Refused" or "Planning Application Withdrawn" submitted since January 2020.

Disclaimer

The project data (site locations, capacities, planning references) comes from the official REPD dataset and is factual. The NIMBY analysis, scores, and commentary are AI-generated and should not be treated as authoritative. As the app puts it: "The opinions themselves are made up, and the points don't matter."
