The Port of Los Angeles, the busiest container port in the country, recently committed to transition a 40-acre marine terminal to solar power. The project is partially funded by a $14.5 million grant from the California Air Resources Board. When completed, it is projected to reduce greenhouse gas emissions by 3,200 tons per year. This is part of a bigger trend. Global companies are investing more than ever in wind, solar, and other forms of renewable energy to gain federal tax credits, grants, and other incentives.
