Most climate scientists agree the warming trend that has prevailed in Tucson and worldwide since the 1980s and ’90s is largely if not completely caused by heat-trapping greenhouse gases emitted into the atmosphere from the burning of oil, coal and other fossil fuels.
Agrivoltaics could result in more food, more energy, lower water demand, lower carbon emissions, and more prosperous rural communities, says an Oregon State University researcher. He plans to build a farm to prove the point.
