It was so nice to get out in the garden and play in the dirt today. I got one bed cleaned out, and planted the shallots, the put in the tulips (way too late) in the bed at the back of the house. I have some irises to plant tomorrow and that's about it. Then I'm going to start working on the new raised beds ( Read more... )

I recently replaced my old 60% furnace with a new HE 97% furnace with dual stage burner and variable speed blower. One of the things the tech guy noted was that I would never have to use my whole house fan to heat/cool the house since the new blower was significantly more powerful and uses less electricity than the old 30 year old motor for the whole house fan. Anyway, perhaps you can get a new blower motor that doesn't suck as much power and costs less to purchase/install than a whole system. Just a thought.

It may be "Just a thought" but it's a good one. I got the rundown on the advances in blowers at school. Who would have thought? There isn't much you can do to electric motors to make them more efficient, but they've done a lot of work on the variable frequency controllers, blade design and air path ( ... )

I'm planning to build a small energy efficient house, and I wish I'd taken a class on energy infrastructure! Where can I find reliable info?

There really aren't any great single sources, so it all depends on what you are looking for. Mother Earth News covers a lot of the topics, but not very deeply. Home Power Magazine tends to be heavy on energy generation, but they also care about saving energy, because saving a watt is a lot cheaper than generating a watt.

There are a lot of good books about energy saving construction methods and design, including "alternative" options like straw bale, cob, cordwood or earthship, or even going with energy efficient traditional stick-built. A lot of it depends on what sort of weather conditions are at your building site. Give me some idea, and I can hopefully point you in the right direction.
