# Research Ideas & Future Work

This document outlines potential research directions, data improvements, and analyses that could extend the current US Data Centers geospatial research infrastructure.

## Priority Next Steps

### 1. Backfill Power Capacity Data
**Status**: Only 5.9% of facilities have `power_mw` values (108/1,833)

**Approach**:
- Scrape Baxtel data center database (requires paid subscription)
- Use Data Center Map API/scraping
- Cross-reference with utility interconnection queue filings
- FOIA requests to state utility commissions for large loads

**Research Impact**: 
- Enable capacity-weighted concentration metrics (current analyses are facility-count only)
- Correlate power capacity with demographic/environmental variables
- Identify "hyperscale" facilities (>100 MW) vs. edge/enterprise (<10 MW)

**Implementation**:
```python
# Add capacity-weighted HHI calculation to analyze_dc_tract_concentration.py
capacity_weighted_hhi = sum((mw_i / total_mw) ** 2 for mw_i in tract_capacities)
```

---

### 2. Operator Name Deduplication
**Status**: String fragmentation inflates operator counts ("Meta" vs. "Meta, Inc.", AWS variants)

**Approach**:
- Create `operator_mapping` table with canonical names
- Use fuzzy matching (e.g., `fuzzywuzzy` library) to standardize
- Add `operator_canonical` column to `master_data_centers`

**Research Impact**:
- Accurate hyperscaler market share analysis
- Study operator-specific siting strategies (AWS hydro, Microsoft nuclear, Meta solar)
- Enable "operator power" political economy analyses

**Script**:
```python
# operators_dedupe.py
import pandas as pd
from fuzzywuzzy import process

# Load unique operators
operators = pd.read_sql("SELECT DISTINCT operator FROM master_data_centers", conn)

# Manual + fuzzy matching to canonical names
canonical_map = {
    "Meta": ["Meta", "Meta, Inc.", "Meta Platforms", "Facebook"],
    "Amazon Web Services": ["AWS", "Amazon", "Amazon Web Services"],
    # ... etc.
}
```

### 3. Water Stress Overlay
**Status**: 257 HUC8 watersheds contain data centers; 15 watersheds hold 50% of facilities

**Approach**:
- Join to USGS WaterWatch streamflow data
- Add USGS Drought Watch indicators by HUC8
- Correlate data center density with:
  - Groundwater depletion rates
  - Surface water withdrawal permits
  - Drought frequency/severity (USDM historical data)

**Research Questions**:
- Are data centers sited in water-stressed watersheds?
- Do high-density clusters (Loudoun County, Columbus OH) face water constraints?
- Compare water stress in hyperscaler non-metro sites (Columbia River corridor) vs. metro clusters

**Tables to Create**:
- `watershed_water_stress` - HUC8-level water stress indicators
- `data_center_water_risk` - Per-facility water-stress exposure

**Notebook**: `water_stress_analysis.ipynb`

---

### 4. Opposition Cases Overlay
**Status**: Anecdotal evidence of community opposition to new data centers

**Approach**:
- Compile cases of rejected/delayed data center proposals (news archive scraping)
- Geocode opposition cases, join to demographics/hazards
- Test hypotheses:
  - Do wealthier/more educated communities successfully block projects?
  - Are opposition cases more common in water-stressed or drought-prone areas?
  - Do smaller non-metro communities have less bargaining power?

**Research Questions**:
- What predicts opposition success?
- Are opposition cases spatially clustered?
- Do demographics differ between accepted vs. rejected sites?

**Output**: `opposition_cases_analysis.md`

---

### 5. IM3 Forward Projection Integration
**Status**: IM3 model includes projected data center demand growth

**Approach**:
- Load IM3 projected demand scenarios (2030, 2040, 2050)
- Overlay projected growth with:
  - Current grid saturation (% of generation within 50 km)
  - Water stress indicators
  - Land availability (zoned industrial parcels)
- Identify regions where projected demand may exceed infrastructure capacity

**Research Questions**:
- Which states face grid saturation from data center growth?
- Are projected sites in water-stressed watersheds?
- Does IM3 assume spatial distribution patterns consistent with current siting?

**Notebook**: `im3_projection_overlay.ipynb`

## Methodological Extensions

### 6. Time-Series Analysis of Cluster Growth
**Approach**:
- Use `rfs_year` (ready for service) from cable data and EIA generator vintage
- Reconstruct data center siting over time (requires RFS dates for facilities)
- Animate cluster formation in interactive map

**Research Questions**:
- Did Ashburn VA become dominant before or after major cable landings?
- Do clusters grow via agglomeration (new facilities near existing) or simultaneous build-out?
- Correlation between energy infrastructure build-out and data center growth

**Data Needed**:
- Facility RFS dates (scrape from press releases, Baxtel historical data)
- Historical tract demographics (decennial Census + ACS back to 2000)

---

### 7. Network Effects: Fiber Route Proximity
**Status**: Current analysis tests submarine cable proximity (negative result)

**Approach**:
- Obtain fiber optic backbone route GIS data (from FCC, carriers, or Infrapedia)
- Test proximity to long-haul fiber routes (not just submarine cables)
- Hypothesis: Data centers cluster near fiber, not cables

**Data Sources**:
- FCC Form 477 fiber deployment data
- Infrapedia fiber route database
- State-level fiber maps (e.g., Virginia Broadband Map)

**Expected Result**: Positive correlation (unlike submarine cables)

---

### 8. Land Use & Zoning Analysis
**Approach**:
- Join data centers to local zoning classifications (industrial, commercial, etc.)
- Analyze land prices in data center tracts before/after facility construction
- Correlate with property tax revenues

**Research Questions**:
- Do data centers drive local property value increases?
- Are they preferentially sited in already-zoned industrial areas?
- Do host communities capture tax base growth?

**Data Sources**:
- Zillow Home Value Index (ZHVI) by ZIP
- ATTOM property tax assessments
- Municipal zoning GIS layers (city-specific, requires scraping/FOIA)

---

### 9. Environmental Justice Scoring
**Approach**:
- Compare data center host tracts to EPA's EJScreen indices
- Add CalEnviroScreen-style burden/benefit framework
- Test if data centers increase cumulative environmental burdens

**Metrics**:
- Air quality (PM2.5, ozone)
- Hazardous waste proximity
- Superfund site proximity
- Heat island effect (LST from Landsat)
- Noise pollution (traffic, cooling systems)

**Expected Challenge**: Data centers may improve local metrics (compared to heavy industry) but increase water/energy consumption

---

## Policy & Political Economy Research

### 10. Tax Incentive Analysis
**Approach**:
- Compile state/local tax incentives for data center siting (property tax abatements, sales tax exemptions)
- Create `data_center_incentives` table with per-facility incentive details
- Correlate incentive generosity with:
  - State fiscal health
  - Local government bargaining power
  - Facility size/operator

**Research Questions**:

- Do incentives predict siting decisions (natural experiment approach)?

**Data Sources**:
- Good Jobs First Subsidy Tracker
- State economic development agency press releases
- Local news archives

- Wage effects in host tracts?

**Data Sources**:
- BLS QCEW
- Census LEHD Origin-Destination Employment Statistics (LODES)

---

### 12. Energy Cost Pass-Through
**Approach**:
- Join to state-level electricity rate data (EIA, utility rate tracker)
- Test if data center density correlates with residential rate increases
- Natural experiment: Compare rate trajectories in high-DC vs. low-DC states

**Research Questions**:
- Do data centers drive residential rate increases (capacity cost allocation)?
- Are rate increases concentrated in utility service territories with large data center loads?
- Do states with retail choice (deregulated markets) see different effects?

**Data Sources**:
- EIA Form 861 (retail rates by state/utility)
- Utility rate case filings (state public utility commissions)

  4. Water stress hot spots
  5. Energy infrastructure saturation

**Output**: `story_map.html` (standalone web page)

---

### 17. Policy Brief Generation
**Approach**:
- Auto-generate policy briefs from analysis outputs
- Targeted audiences:
  - State legislators (energy/water policy)
  - Local governments (tax incentive negotiation)
  - Environmental justice advocates

**Template**:
```markdown
# Data Center Siting in [STATE]: Key Facts for Policymakers

- **Host communities are Z% wealthier** than state average
- **A% of state generation is within 50 km of a data center**
- **Top watershed holds B facilities** (water stress: [HIGH/MEDIUM/LOW])
```

---

### 18. Comparative International Analysis

- Features: demographics, energy capacity, fiber proximity, tax rates, water availability
- Test on historical data (train on pre-2015, test on 2015-2025)

**Use Case**: 
- Identify "likely future sites" for proactive policy intervention
- Warn communities of potential incoming projects

---

### 20. Cooling Technology Analysis
**Approach**:
- Classify facilities by cooling type (air, water, hybrid)
- Correlate with:
  - Climate (CDD: cooling degree days)
  - Water availability
  - Facility size

**Data Sources**:
- Manual classification from news/press releases
- FOIA requests to water utilities (cooling water withdrawal permits)

**Research Questions**:
- Are water-cooled facilities concentrated in water-stressed regions (paradox)?
- Do hyperscalers use more efficient cooling (e.g., Meta's Prineville OR evaporative cooling)?

---

### 21. Bitcoin Mining Facilities

- Test if Bitcoin mines face more opposition (negative perception)

**Data Sources**:
- Cambridge Bitcoin Electricity Consumption Index (has facility locations)
- News archives of mining farm proposals/rejections

---

### 22. Disaster Resilience & Redundancy
**Approach**:
- Model simultaneous hazard exposure across data center clusters
- E.g., "What % of US data centers are in wildfire risk zones?"
- Identify single points of failure (e.g., Ashburn VA = 20% of US capacity)

**Research Questions**:
- Is the current spatial distribution resilient to climate change?
- Should policy incentivize geographic diversification?

**Output**: `disaster_resilience_report.md`

---

### 23. Edge Data Center Network
**Approach**:
- Separately analyze edge facilities (<1 MW) vs. hyperscale (>100 MW)
- Test if edge DCs follow different siting logic (population density > energy cost)

**Data Challenge**: Current inventory does not distinguish edge vs. hyperscale (need `power_mw` backfill)

---

### 24. Carbon Intensity of Host Grids
**Approach**:
- Join to EPA eGRID subregion carbon intensity (lb CO₂/MWh)
- Calculate per-facility estimated carbon footprint (if `power_mw` available)
- Compare to corporate renewable energy procurement (RECs, PPAs)

**Research Questions**:
- Are data centers disproportionately in high-carbon grids?
- Do hyperscaler renewable commitments offset grid carbon?

**Data Sources**:
- EPA eGRID
- Corporate sustainability reports (Google, Microsoft, Meta, AWS)
