Wind and renewables in general already out-compete oil. If you think about a traditional power plant, the costs can be lumped into 4 categories:
Construction
Maintenance
Demolition
Fuel
Over the life of the plant, fuel has always been the dominant cost. With renewables, there are no fuel costs. Sure, the other costs might be slightly higher (wind farms are in remote areas, you have many small generators as opposed to a few big ones - solar is still dirt cheap though) but the fuel cost being non-existent easily overrides that.
The biggest travesty is that we basically have renewable energy sold at oil prices, creating insane profit margins for renewables.
Also I have no idea what you mean by the IRA and keep wondering what Ireland has to do with all this.
