The Good Neighbor Environmental Board released a report December 14 concluding that all renewable energy planning and land-use projects along the U.S.-Mexico border should optimize the use of rooftops, brownfields, greyfields, and under-used federal properties. The Potential Environmental and Economic Benefits of Renewable Energy Development in the U.S.-Mexico Border Region report found that these projects should provide adequate incentives and assurances to encourage developers and landowners to take full advantage of opportunities to site renewable energy facilities at environmentally preferable locations.
