Energy/Nuclear, Who Lobbies on This Issue
Organizations lobbying on energy/nuclear policy issues, as disclosed in Senate LDA filings.
Energy/Nuclear is one of the most heavily lobbied general issue areas in the LobbySpend index. 65 organizations have collectively reported $1.1B in disclosed lobbying activity tagged to this issue code — a billion-dollar-plus footprint that places it firmly in the top tier of LDA-disclosed federal engagement.
What These Numbers Mean
Participation on Energy/Nuclear is broad, with 65 distinct registrants reporting activity. Issue areas at this level of participation typically span multiple industries with parallel but distinct policy interests.
The disclosed-spend leader on Energy/Nuclear is US Chamber of Commerce (grade B) at $387.8M — more than 361% ahead of the #2 filer Business Roundtable ($84.2M). A wide gap usually indicates a single anchor stakeholder whose core business is heavily exposed to the issue.
Issue codes are one of the most useful but least intuitive parts of LDA filings. Registrants must attach at least one general issue area code to each quarterly filing, but the code list is fixed and broad — the same code can cover several distinct policy debates, and filers often use a single code even when working multiple narrower topics within it. The dollar totals on this page are filer-allocated and should be read as a directional signal of where attention is concentrated rather than as audited line items. The original filings are publicly available through the Senate Office of Public Records; the campaign-finance research project at OpenSecrets uses the same filings as one input.

How to Read This Page
The issue page rolls up every LobbySpend-tracked filer that has reported lobbying activity tagged to the Energy/Nuclear general issue code at any point in the years tracked. The total-spend number sums filer-allocated dollars across those filings, deduplicated against amendments. The organization count reflects unique registrants, not unique filings — a registrant that filed every quarter for five years is still counted once.
Cross-cutting issues (Taxation, Health Issues, Defense) tend to attract a long tail of mid-tier filers from many sectors at once. Narrow issues (Postal, Tobacco, Religion) concentrate participation in a small set of anchor stakeholders. Both patterns are normal in LDA data — the structure of the issue-code list is what produces the difference, not any underlying judgment about the relative importance of the policy area. For the full methodology, including how the Influence Score weights total spend, issue breadth, and revolving-door staffing, see the methodology page.
