they do, sometimes they use drycoolers, they are smaller. Or if there are none then they have to work into district heating to get the return water to 40-45c
These kind of powerplant uaually are peaker plant, only designed to do intermittend power generation. Usually also a bit smaller (<500MW) than large baseload generator plants (nuclear/coal >1GW)
They are however usually located near larger bodies of water for cooling.
Lastly gas plant are a fair bit more efficient (50-60%) where Coal (40%) and Nuclear (30%) have a lot more waste heat to get rid off.
They do they just not shaped as towers. They most likely using more flat design with fans. Also cooling towers dont work in all climates. If its too humid cooling tower isnt as good as contruption with fan.
Plenty of them do, and plenty of nuclear plants (famously associated with them) don’t. If you have a convenient river nearby, there’s no point, just use that to cool. A big ol cooling tower is just one option for a heat exchanger, too. And finally, if the power plant is using gas turbines, there’s no water to be cooled, just hot exhaust.

Who says they don’t?
At a certain size and using certain technologies they absolutely do.
Take for example Chalk Point Generating Station

They do. Source – I work at a gas power plant with a cooling tower.
