You are right about solar panels being built in China, but windmill components are usually built in local factories, because they are very hard to transport.
You might call the dominance of the Chinese solar manufacturers a national security risk, but as long as we have the knowledge and resources to theoretically build them in the West (albeit more expensively), they are easier to replace than for example Saudi-Arabian oil or Russian natural gas.
