XML schema support
I see that neither SDG&E, nor PG&E include cost information in the green button data. This severely limits the potential use of the data since the savings can only be proven with the cost reduction!
Even between these two utilities, I see SDG&E including ElectricPowerUsageSummary tag with billing details which is missing in PG&E data! We should have some consistency in terms of details supported by utilities instead of making them optional and leaving it to utilities.
Just by showing that one uses more energy during say 2-4 PM doesn't guarantee cost reduction if you postpone the usage to say, 6-8 PM. This will realize in reduced cost, only if there is time of use rate in effect, which may be the case for electricity customers (not likely for gas customers).
Without rate info and the cost calculation rules available, it is hard to make a case for savings.
We should encourage utilities to expose the green button usage data (including rate and cost) using an API which can be tricky to secure, especially with the privacy concerns.
Till that happens, I don't see lot of opportunities for developers.
