I think it's exactly what I'm thinking about, unless I'm missing something specific that you'd like to put forward?

If I own a bottled drinks company and the energy cost is 10p a bottle but a new, more efficient process is invented that would lower my energy cost to 5p a bottle, that's going to be looking like a wise investment to make. A few pence over several thousand products adds up pretty quickly.

I could either pocket the difference as extra profit, lower my unit price to the consumer to make my product more competitive in the market, or a bit of both.
