Welcome to NRWAL!

The National Renewable Energy Laboratory Wind Analysis Library (NRWAL):

1. A library of offshore wind cost equations (plus new energy technologies like marine hydro!)
2. Easy equation manipulation without editing source code
3. Full continental-scale integration with the NREL Renewable Energy Potential Model (reV)
4. Ready-to-use configs for basic users
5. Dynamic python tools for intuitive equation handling
6. One seriously badass sea unicorn

To get started with NRWAL, check out the NRWAL Config documentation or the NRWAL example notebook. You can also launch the notebook in an interactive jupyter shell right in your browser without any downloads or software using binder.

Ready to build a model with NRWAL but don't want to contribute to the library? No problem! Check out the example getting started project here.

Installing NRWAL

Option 1: Install from PIP or Conda (recommended for analysts):

1. Create a new environment:
   conda create --name nrwal

2. Activate directory:
   conda activate nrwal

3. Install reVX:

   1. pip install NREL-NRWAL or
   2. conda install nrel-nrwal --channel=nrel

Option 2: Clone repo (recommended for developers)

1. from home dir, git clone https://github.com/NREL/NRWAL.git

   1. enter github username
   2. enter github password

2. Create NRWAL environment and install package

   1. Create a conda env: conda create -n nrwal
   2. Run the command: conda activate nrwal
   3. cd into the repo cloned in 1.
   4. prior to running pip below, make sure the branch is correct (install from master!)
   5. Install NRWAL and its dependencies by running: pip install . (or pip install -e . if running a dev branch or working on the source code)
