Quote:This I don't understand. Just like central air, or on demand hot water, if solar power is a plus, then it increases the value of the home. So, it doesn't lock the original owners in, it simply increases the value (or price). So do granite counters and wood floors and people install them all the time.It is quite an undertaking to convert from one system type to another. Rather than credits, I think it would be helpful to provide low interest loans (maybe a special class of 2nd mortgage) attached to the home. For northern climates, I think ground installed geothermal heat pumps make the most sense for domestic heating, with electricity generation being done by the best renewable method for that area (nuclear, wind, geothermal steam, solar, tidal, etc.).
As to the rest of your argument, maybe so, maybe no. However, without the incentives and rebates, solar looks pretty poor for my area.
