Rebekah and I recently had the pleasure of helping the Abundance Foundation create their carbon-free office. We ran simultaneous workshops on installing an off-grid PV system (Rebekah) and constructing a solar air heater, detailed instructions of which can be found here:

If we worked at Abundance, and tanked up with fuel at next door Piedmont Biofuels (if we still had a funcitoning diesel, which, unfortunately, we don't), then we could go from our carbon-free home, in a carbon-free car, to a carbon-free office. One more piece of the puzzle!
