Who said anything about more expensive? As for "similar heights", the largest radio tower was the Warsaw Radio Mast, which was 2164 ft before it collapsed. The currently tallest radio mast is the KVLY-TV mast which is 2063 ft. This would be 26% taller than KVLY, would be free-standing (unguyed), and would be solid (wind cannot blow through it). This tower is more comparable to a occupied structure.
The current highest capacity wind turbines are 7.6 MW. I haven't been able to find figures on the area proposed for the collector area of this tower, but it is possible that 30-50 simpler and proven wind turbines or 1 to 5 concentrated solar units might be able to replace this tower.
You know they wanted to build one of these in Australia, right? The proposal stalled and it looks like it will not be built.
