I thought TPIC was an interesting one. They are one of the leading wind-blade manufacturers and accounted for approximately 18% of all sold onshore wind blades globally in 2019 with over $1.4 billion in net sales and more than 9,500 wind blades sold. These turbine blades can last up to 20 years, but many are taken down after just 10 so they can be replaced with bigger and more powerful designs. With solar and wind energy increasingly popular this could be a company to watch.
