Ownership of renewable energy stocks is extremely crowded, per the index provider MSCI. President Biden has expansionary plans for clean energy. He has a plan — a Clean Energy Revolution — to address the issue of climate emergency. He sees America as becoming a 100% clean energy economy by 2035 and having net zero emission by 2050.

If this is not enough, U.S. Treasury Secretary Janet Yellen recently said that she will back an effort by top U.S. regulators to evaluate the likely risk that climate change is causing to America’s financial system, as quoted on an apnews article.

Yellen says the regulatory review, which will be done by the Financial Stability Oversight Council, will scrutinize whether banks and other lending institutions are correctly assessing the risks to financial stability.

Apart from the social standpoint, this investing practice has a valid reason for increased gains. As per the source, lesser focus on environmental issues by the companies may result in lawsuits, fines and damages. In most cases, it has been seen that sound corporate governance leads to greater corporate durability.
