Energy emitted by the Sun in the form of electromagnetic waves and particles. Distributions are maps of sunlight climatology as well as basic weather observations such as incident solar radiation and cloud cover. Assessments evaluate the profitability, suitable locations, and effects of solar energy generation on biological resources and other uses. Predictions are the results of models or projections of future solar energy potential, effects, and risks; these data include predicted changes due to economic, regulatory, technological, and environmental changes.
