With Senator Kamala Harris now on the ticket, Democratic nominee Joe Biden is angling to enhance his environmental credentials ahead of the November presidential election. The Biden campaign’s ambitious clean energy plan plays no small role in this ongoing effort. But in an unfortunate coincidence, in recent weeks taxpayers have learned that they are still paying for the mistakes made when the former vice president was last in office. Without demonstrating that the Biden-Harris team has learned from these mistakes, the current platform risks creating an even larger round of taxpayer-funded failures.
