No? Just about any financial transaction, insurance calculation and a lot of telcos operations run mainly of cobol.

You can throw money at electricity use, and COBOL is compiled to machine code so the power usage is much less of a concern than it would be in an interpreted language.

Much higher on the list of concerns is finding capable COBOL developers, ongoing maintenance, and security. Those are all things that you can't just throw money at.
