After Donald Trump won the election, companies that focus on renewable energy, like solar and wind power, saw their stock prices drop.
This happened because Trump has promised to roll back policies that support green energy and instead focus on traditional energy sources like oil and gas.
Trump's win is a blow to the green energy industry, which had been gaining momentum under the previous administration's initiatives.
While some investors are worried about the future of clean energy, other sectors, like the fossil fuel industry, are celebrating Trump's return.
