Offerings are matched on the Form D industry group (Coal Mining, Electric Utilities, Energy Conservation, Environmental Services, Oil and Gas, Other Energy) and the company’s business address, one offering per company, funds excluded. Each filing reports how many investors have already invested, not who they are, so an investor in two offerings counts twice. Run the same search on sec.gov.
