I'm not a physicist, but maybe I can act as a bridge here.
giraffedata was comparing two possible scenarios:
1. Continue to use the CRTs until they were due for replacement anyway (let's call that time T1), then replace them with LCDs.
2. Discard the CRTs now (let's call that T0) and replace them with LCDs
In scenario 2 you use less electricity in the timespan from T0 to T1, which saves money, but you also move the expense of buying the LCDs from T1 to T0, which means you lose the profit you could have made from investments of that money between T0 and T1.
For a profitable business, the most natural investment is in its own operations, which is why giraffedata was talking about income from the core business.
