When it comes to finding a green way to power our homes, we rarely think beyond solar panels. For quite some time, although photovoltaics haven't been totally affordable, they've seemed like the only realistic option. But according to an article in the LA Times, residential wind power is steadily gaining in popularity.
According to the LA Times article, "roughly 10,500 small turbines were sold to homes, farms and businesses nationwide in 2008." And, although 2009 stats aren't availble yet, the American Wind Energy Assn says demand remained strong even through the recession (and even though wind power isn't cheap either).
The article also addresses the rising popularity of geothermal power, as well as the new rebates for solar hot water heaters.
All in all, the moral of the story seems to be that although all of these alternative energy sources are gaining in popularity many are still prohibitively expensive upfront. It seems that the main hurdle is making these options more affordable for middle class families.
