NAPA, Calif., April 16, 2025 (SEND2PRESS NEWSWIRE) -- As Earth Day approaches on April 22, Domaine Carneros is raising a glass to a significant milestone: over two decades of pioneering solar energy in the wine industry. What began in 2003 as the world's largest winery solar installation has evolved into a cutting-edge microgrid system that now provides nearly 80% of the winery's energy needs while reducing carbon emissions by 375 metric tons of CO₂ annually, equivalent to powering 50 homes for a year.
