In the summer only the third portion occurs, smaller since less lighting is required and there is no air conditioning. <br /><br />This is typical although newer construction does not use resistance heating. Anyway, at these typical Pacific Northwest rates solar PV is going to compete? <br /><br />It would be different if there were a fee for carbon dioxide emissions. Then more nuclear power plants would make sense around here as electricity consumption is highest in the winter and would be even more so as people once again install resistance heaters. David B.

Your comments on storage, grid expansion and false hopes sold on plummeting SPV panels are equally depressing.<br /><br />We've discussed geothermal before, I didn't like what MacKay had to say then either. Living as close as I do to the largest geothermal installation in the world (Geysers, CA) might make me more of a hopeful believer than is prudent.<br /><br />I saw recently that wind is vastly outpacing solar in the US. On this one, perhaps I should listen to the market ... noting that while the wind is always blowing somewhere, it isn't always blowing where and when we most need it.<br /><br />Nukes are all but required to shoulder most of the demand it seems.Brandon R.
