comment How much energy will continuously running a furnace fan use?
-1 This will yield a completely incorrect result as it assumes that the motor is a resistive load which it is not. The motor running at constant speed is predominantly a reactive load. You need to distinguish between real, apparent, and reactive power in order to determine the correct result. Using the method in the answer will give you incorrectly high results for fan power consumption because its power factor at running speed is much less than unity.

comment How much energy will continuously running a furnace fan use?
@gregmac As far as I can tell, in all cases in your tests above you are measuring current that is proportionate to apparent power, but not real power. Real, apparent, and reactive power are related but not the same. Your utility's watt-hour meter measures real power. When the fan is running at constant speed, it is most likely predominantly a reactive load with low power factor. So, you will read high current even though it is not using much power.

comment How much weight can you mount to a wall?
A limiting factor of wall mount shelves is their depth. This answer might help you figure out whether you need free-standing shelving or whether you can wall mount.

comment Decent Brand Names for Beginner Carpentry
it seems like a more useful question along the same lines would be something like "What tools do I definitely need and which can I get away without for Project X?". Someone ought to ask that if it hasn't already.

comment What should I consider when designing a simple bookcase that will be built without power tools?
For insight into wall-mounted vs free-standing shelving, you might want to read my answer here. Remember that books are very dense (they hardly float in water) - they are the densest item I ever store in my home. Accordingly, you might want to work out how much weight you'll actually be storing and make sure your proposed shelving will actually support it.
