In a rare interview this week, Billionaire CEO of Berkshire Hathaway Warren Buffett discussed his reason for successfully lobbying for a change in net metering in Nevada, where Buffett owns the state’s largest electric utility, that effectively stopped the growth of residential solar installations in the state. Net metering rules regulate the amount of credit homeowners with solar panels get when exporting surplus energy generated from their installation back onto the utility grid, which the utility can then sell to other customers. His logic is simple, he wants to have to pay wholesale electricity rates for the energy generated by rooftop solar instead of the same price NV Energy is charging these customers since he says it will penalized customers without solar panels.
