Forecast Methods and Scenarios Comparison for Renewable Energy Production

According to the historical data of renewable energy production and cumulative production in U.S., this paper forecasted the trend of its production after 2011. First, changes of the historical U.S. renewable energy production were analyzed. Second, growth cycle of production was confirmed based on the above analysis, and phrased production forecast was given by power fitting curve. Third, this paper presented the non-phased production forecast by the second fitting equation calculated from the ratio of production and cumulative production. Through comparing the scenarios of phased prediction and non-phased forecast, to the renewable energy production forecast released by the U.S. Department of Energy, we concludes that average curve of standard and low scenarios is more in line, and the non-phased forecast can draw the range of future production changes. Finally, impact of U.S. renewable energy development on China is studied in the discussion of the results.
