A point NNadir frequently makes when talking about PV needs more attention. That it's a "rich boys toy." Well, it isn't just PV. It also applies to conservation, which everyone here agrees is imperative at this point, regardless of what technology we get our electricity and heat from.
If you're poor, you can't shell out a thousand dollars to replace your 1960's refrigerator. You can't afford better insulation. Heck you can hardly afford to "invest" in a compact fluorescent lightbulb -- every dollar is stretched.
And, you don't have to be particularly poor to end up renting. Even if you have $400 or so, you aren't allowed to replace a window (and can only get the landlord to do it if it is badly damaged, and then only if you are lucky.) Most of the appliances are old, but you don't own them so if you use your own you have to stow them away and endure extra moving costs. Forget putting anything on the roof, and you cannot touch the plumbing. Plus you wouldn't want to anyway: you don't have an equity stake in the property. If you're lucky you have a sunlit lawn and no-one will complain if you set up a solar air heat unit. More likely you only have a few windows in an apartment.
While energy standards in new public housing builds may address some of the destitute -- the old ones stay in service for a good while with little improvement. And the huge number of renters in private units don't get helped by this.
Though it's hard to pin down, because per-capita energy use will be restricted by income, it's pretty much a no-brainer that per-capita energy
efficiency for comparable uses of energy is lower for those with lower incomes. You can trounce around at your whim in the latest (2001) survey data here:
http://www.eia.doe.gov/emeu/recs/recs2001_hc/2001tblhp.htmlWhile all the "home and garden" news and articles are great for homeowners, and homeowners should take heed and
improve their own properties, there is simply no relief on the horizon for the poor or renting. That segment is stagnant.
Granted there are some negative feedback mechanisms -- save a guy $6 per month in electricity and he might turn up the thermostat a few degrees and use about as much energy. I don't think that quashes the general inclination to help our fellow man, though -- either we help him through an improved environment via reduced energy usage, or through an improved quality of life with the same energy usage.
So what can be done about conservation efforts here?
Lobby the landlords? Free appliance efficiency audits and microcredit for self-furnishers?
How to do it? Work through HFH? Through existing utility programs? Local governments? Use door-to-door canvassing? "bumvertising"?
I'd be interested to know, if you were able to set up one modest, local, charity-based program to address energy conservation in these sectors -- what would you do and how? Are there any existing programs you think are particularly outstanding?
