The President-elect of the United States of America recently shot out a dire but widely expected warning, declaring that in his second term he would support the domestic fossil fuel industry at the cost of clean energy. The first casualty of such a change could be the Inflation Reduction Act, a potent US government incentive designed to promote the clean energy sector. This move is likely to be accompanied by a squeeze on funding for clean energy technology (unless legally guaranteed), especially in Republican states.
