The 7 Best Green Energy Stocks to Buy in October Investors, including those who own green energy stocks, have myriad reasons to be bearish currently. Inflation remains high, with the year-over-year CPI registering 8.3% in August. The Fed responded as expected, raising interest rates by 0.75 percentage points, or 75 basis points, on Sept. 21. That rate increase, the central bank’s third straight 75 basis-point hike, has resulted in the market taking yet another downturn. The SP 500 dipped to 3,670 on Sept. 22. That is less than 100 points off its 2022 low of 3,667 which was set on June 16. In short, there are many valid reasons to be wary of stocks. However, forward-looking investors would be wise to recognize the opportunities that exist. One such opportunity is the projected growth of green energy and renewable energy. Polaris Market Research estimated earlier this year that the revenue of the global renewable energy market would reach $1.68 trillion by 2029. That equates to an average annual growth rate of 8.5% , suggesting that the sector will provide investors with serious opportunities despite the market’s current woes.
