Wind and Solar Candidate Project Areas for Princeton REPEAT

<p>This data set contains the GIS data for&nbsp;solar, land-based wind, and offshore wind Candidate Project Areas (CPAs) under base &nbsp;(BLUA). Each record in this dataset represents a &ldquo;Candidate Project Area&rdquo; with attributes such as nameplate capacity, annual generation, model region, distance to transmission, etc. The Lawrence Berkeley National Lab MAPRE tools (<a href="https://mapre.lbl.gov/gis-tools/">https://mapre.lbl.gov/gis-tools/</a>) were used to create this dataset, along with input assumptions adapted from Wu et al 2020 (Grace C Wu&nbsp;<em>et al</em>&nbsp;2020&nbsp;<em>Environ. Res. Lett.</em>&nbsp;15&nbsp;074044) and&nbsp;E. Larson, C. Greig, J. Jenkins, E. Mayfield, A. Pascale, C. Zhang, J. Drossman, R. Williams, S. Pacala, R. Socolow, EJ Baik, R. Birdsey, R. Duke, R.
