As President Biden affirmed in his State of the Union address Tuesday, ambitious clean energy incentives delivered last August are working. In the first three months after the incentives were enacted, corporations announced more than $40 billion in clean energy investment. These are projects to get clean power from the wind and sun and to build or expand factories across the USA to make solar panels, wind turbines, advanced batteries and electric cars. An additional $11.4 billion in such projects was announced in January, bringing the total to more than $51 billion.
