The solar energy boom is the modern equivalent of the California Gold Rush of 1848.
Data from Wood Mackenzie Power & Renewables and the Solar Energy Industries Association notes that it took 40 years to reach 1 million solar installations in the U.S., but just three more years to hit 2 million installations. And the forecast for 2021 alone is 3 million installations.
Green energy exchange-traded funds (ETFs) are on the rise as earnings improve and investors pile into solar stocks. This is evidenced in the bellwether Invesco Solar ETF (TAN), which has more than doubled over the past year, though lately, it has cooled off.
