Iowa's largest utility MidAmerican Energy got $308 million in state and federal tax credits in 2018 for generating wind energy, then hid behind a front organization called the REAL Coalition to push legislation to add a tax on customers who install rooftop solar panels.
The utility admits it is a member of the shadowy lobbying organization. However, that's about the only thing the privately held utility – part of the conglomerate Berkshire Hathaway run by Warren Buffett – will disclose about the secretive lobbying effort.
