Yeah, one of the most powerful levers the federal government could have with respect to climate is to provide financing support for renewables. If you reduced the cost of capital for solar, wind, and batteries (or nuclear for that matter) to the price of 30 year US treasuries, it’d crush all fossil fuel power plants and provide a spur to the economy. In addition, cheap electricity would be a huge long-term boost to the economy, it’d drive electrification of transport/heating/industry, and the cost to taxpayers would be almost nil.
