At this point it's just a concept. I'm not sure how "best intentions" fits
into a scientific method, but certainly we can look at total amount of
electricity generated and at amount of electricity generated per house. We
can certainly get a figure for BTUs generated per solar hot water system,
total and average for a community. What are the average R-values for House
construction? We recycle wastewater, which other communities may not do, but
water usage averages per person or per household are relevant and can be
compared with national or regional averages. Are there valid ways to compare
natural gas usage, propane usage or electricity usage? Probably only within
each energy source category. Food produced per community member in community
gardens? Hard to measure... Construction cost comparisons? Most of our
systems were built before the more generous State and Federal tax writeoffs
and/or grants, so I'm not sure how we can compare those. I'm interested to
see what factors others may come up with.

The point is neither bragging rights nor a peer-reviewable precise audit,
but a forum that other communities can use to decide on their own energy
efficiency paths. Anyone interested, please contact me off the list (let's
save some surprises for the conference)
