Question about ETF Share Price

So if you’ve got an ETF like INRG which ‘tracks the performance of an index composed of 30 of the largest global companies involved in the clean energy sector’ will the share price of the ETF change based on what the prices of the underlying stocks are doing? Or does the share price fluctuate based on it being bought and sold by investors? Or somehow both and the price is an interaction of the underlying stock prices and the actual ETF being bought and sold?

I’ve read about ETFs but don’t quite understand it. For instance, if no one is buying the ETF will the price just not change even if the underlying stock prices are?
