Takeaways for investors
Energy sector takeaways for investors
The largest energy companies are in the oil and gas industry, which could be problematic for those focused on ESG investing. While most oil companies are now investing in renewable energy, just about all of them have had their high-profile issues, such as oil spills or climate change denial. If that's not a dealbreaker, these tend to be stable businesses and some of the higher-paying dividend stocks.
Even if you want to stay away from Big Oil, the energy sector also has renewable energy stocks. You won't find them among the top 10 (at least not yet), but they provide a more sustainable way to invest in energy companies.
