7. Get an [API key for EIA's OpenData portal](https://www.eia.gov/opendata/register.php). This key is needed to download projected fuel prices from the 2019 Annual Energy Outlook.
-8. Create the file `PowerGenome/powergenome/.env`. To this file, add `PUDL_DB=YOUR_PATH_HERE` (your path to the PUDL database), `EIA_API_KEY=YOUR_KEY_HERE` (your EIA API key) and `RESOURCE_GROUPS=YOUR_PATH_HERE` (your path to where the resource groups data from Step 6 are saved). Quotation marks are only needed if your values contain spaces. The `.env` file is included in `.gitignore` and will not be synced with the repository. See the [SQLAlchemy documentation](https://docs.sqlalchemy.org/en/13/dialects/sqlite.html#connect-strings) for examples of how to format the `PUDL_DB` path (e.g. `sqlite:////<entire path to the folder containing pudl file>/pudl_updated.sqlite`).

If you get any errors when trying to initite the PUDL database, go back and check your path formatting against the SQLAlchemy documentation examples.
9. Update the Consumer Price Index (CPI) data used to adjust U.S. dollars for inflation (see https://github.com/datadesk/cpi#updating-the-cpi). Because the orignial [cpi](https://github.com/datadesk/cpi) package takes ~30 seconds to load, PowerGenome includes a modified version that only stores a handfull of the BLS CPI tables. Update these tables by starting a `python` session and running:
