The naive nature of this comment seems pretty synthetic, but I'll give it a grown up response:
One answer to preserve GDP while shifting to carbon neutral renewables is to increase the cost of fossil fuels through the use of a Carbon Dividend. This consists of three points 1. Taxing carbon fuels at the wholesale market. 2. Providing a dividend to every citizen of the U.S. (mitigates the impact on low income families, estimates range about $4k / person) 3. Provide an adjustment tax at the border punishing other countries like China that do not institute their own Carbon fee structure.
This is a market based solution advocated by James Baker & others within the conservative establishment to help our society accelerate the shift to carbon neutral power. Currently a group of 17 house republican representatives support the measures.
