This article talks about how the United States needs to boost renewable energy investment like Brazil. Brazil is doing well in renewable energy, and the US needs to step up to regain its leadership. The current US laws aren't great at encouraging long-term investments in renewable energy. Brazil shows that investors need guarantees for their money over time to keep investing in green projects. To fix this, the US should make a national rule for using more renewable energy, and power companies should sign long-term contracts to buy renewable electricity. This way, the US can attract more investment in clean energy.
