I have written about Stitt Energy Systems and their high tech homes in the past: http://www.stittenergy.com/ The company has a long record of building energy saving homes in the USA and Canada and their technology has been much reviewed and praised in some of the most prestigious technical journals available here. I learned about them from one of the best magazines in the business, the American Solar Energy Society's Solar Today: http://ases.org/index.php?option=com_content&view=article&id=14&Itemid=22 while working on a project some time ago at my university. I hsve since shown their website and directed audiences to it and hope to do this again in South Asia.
While the idea of near zero utility bills may be a very attractive one in the USA as an example of economizing on expenses in a difficult time, this technology would have vastly more applications in countries in South Asia where residents suffer from power shortages as long as 18 hours a day in some places. Just imagine a home where you do not have to bother about the vagaries of power supply from your local electricity board. Think of a home that does not end up in darkness because the local MLA decides to "borrow" your electricity for his campaign. The possibilities are amazing and well worth looking at for this reason as well. I daresay that whoever gets into this field of high tech housing in South Asia, will end up making more money than they could spend in several lifetimes. Right now, there is no one doing this. Period.
