If the price is right, improved LED technology may bring significant power savings with bulb changes:

Ah, I have been anticipating such a development.

I have been watching my humble garden lights, a wedding gift from earlier this year. The amount of light they give off isn't impressive-- although they are better that way than earlier incarnations of the solar powered garden light, but their longevity is.

Here we are in the "darkest" part of the year, and even with gloomy day after gloomy day, with snow caps on the solar panels, the lights are still on in the morning, before sunrise.

Granted, that is also probably due to advancements in battery and solar panel technology, but all the same it impresses me.

If this bulb is as good as they say it is, perhaps little wind generators for residences could take house hold lighting right off the grid entirely?

I long for the day when affordable power units such as dependable solar/wind generators are available for all. The manufacturers of such devices would make a bundle.

And to Boom Boom, I believe coming off the grid is quite possible if the residence is converted to a 12volt DC system. Not all that large a battery pack would be required. Vehicles are now being produced with their own microwave ovens and inverters plugged into the lighter plug can run several house hold items.

I seem to recall, in fact, a particular EV being promoted for it's ability to provide emergency, house power. Such a residential system change would need all the assists, of course, with solar water heating and a generous photo-voltaic array.

I'm guessing there is no shortage of wind where Boom Boom is, for him it's only a matter of capital outlay. It's still expensive.

I live far enough inside London, and in an older neighborhood, with very mature trees, so I don't get much wind. I was thinking I have a fairly substantial south facing roof ( the house runs east/west) but then it's a gambrel style roof, and maybe the lower angle isn't good for solar panels.


But, these technologies get more efficient, and cheaper all the time. Within a decade, I think it could be possible that everyone will be in the process of retrofitting their homes to either get off the grid, or very substantially reduce there demand on it.

Particularly if the claims I heard a year or so ago that it's possible to harness solar power in the infra red spectrum turn out to be true, and marketable.

Oh there's lots of wind here - I believe Hydro Quebec did a study on offshore wind turbines, then dropped the idea. Meanwhile, one new hydroelectric dam is under construction not far from here (Havre St Pierre), and a second (Chevery) is the planning stages. I've heard talk of one north of La Romaine but it's just talk at present.
