Way not to understand the comment you replied to: Yes, the industry needs gas, not electrical heating. And at the moment, most gas in Germany is used for industrial purposes; some, to heat homes; and some, to generate electricity.

Therefore any gas freed up, by not being used to generate electricity or heat homes, can be used for those industrial purposes in stead. So using nuclear power in stead of gas to generate electricity, and electricity in stead of gas to heat homes, frees up some gas for industrial use.

Sheesh.
