The overall stock market was fabulous last year, but as investors focused on climate change, renewable energy stocks did even better.
Consider that while the SPDR S&P 500 Exchange-Traded Fund Trust, which tracks the benchmark S&P 500, returned 18.37 percent in 2020, the Invesco Solar E.T.F., which tracks an index of solar energy stocks, soared 233.95 percent, according to Morningstar Direct. The Invesco WilderHill E.T.F., which invests more broadly in alternative energy of various types, rose 204.83 percent.
