It collects energy data from a PostgreSQL database, formats it into a PDF, and emails it to a recipient.\n\n## **Core Logic**\n1. **Trigger**: The workflow is scheduled to run monthly via a `Schedule Trigger` node.\n2. **Data Collection**: Connects to a PostgreSQL database and fetches energy data from the `energy_data` table.\n3. **Transformation**: Uses a `Code` node to transform raw database rows into a structured JSON object with metadata like `date_range`, `note`, and `records`.\n4. **PDF Generation**: Sends the transformed JSON to the PDF.co API (`Convert data to pdf` node), which returns a downloadable report URL.\n5. **Email Delivery**: Uses the `Gmail` node to send the report link via email to a configured recipient.\n\n## **Outcome**\n* An energy performance PDF report is automatically generated and emailed monthly.\n* Enables proactive reporting for energy production across multiple plants (solar, wind, hydro).\n* Removes manual intervention in creating recurring performance summaries."
