What this workflow does
This AI workflow has 22 nodes and runs on a schedule (every hour). Along the way it connects OpenAI Chat Model, HTTP Request, Perplexity and Google Sheets and 2 more.
How it runs
Trigger: On a schedule (every hour).
- Fetch Weather Data (HTTP Request): calls an HTTP API
- Fetch Energy Demand (HTTP Request): calls an HTTP API
- Fetch Renewable Generation (HTTP Request): calls an HTTP API
- Combine Energy Data (Merge): merges the data from its input branches
- Energy Governance Agent (AI Agent): runs an AI agent, with model: Governance Model; 7 tools (Energy Calculator, External Data API Tool, Weather Analysis Agent, Policy Compliance Agent…); output parser: Structured KPI Output
- Prepare Sheet Data (Edit Fields (Set)): sets 8 fields: timestamp, renewablePercentage, nonRenewablePercentage…
- Send Sustainability Alert (Slack): uses Slack
- Email Performance Dashboard (Gmail): uses Gmail
- Store Energy KPIs (Google Sheets): append
Services it uses
Before you upgrade to n8n 3.0
Nothing in this workflow is removed in n8n 3.0, so it should import and run after the upgrade.
