Green(ish) heating


Heating with oil? Green it up a bit. Several Connecticut heating oil companies are now offering heating oil mixed with biodiesel -- sometimes at no additional charge.

Ethanol, another biofuel that can be mixed with gasoline, is often criticized for having a low energy yield -- somewhere around 1.3 units of energy yielded for every 1 unit of input [Download pdf]. Biodiesel, on the other hand, has been shown to have a yield of about 3.2. [Download this (big pdf) study sponsored by the USDA and USDOE to see for yourself.]

Ask your oil company to start supplying biofuel.

This is great news. I'd never considered this before, time to make some calls.

Great post, I don't know why the companies don't advertise this sort of thing.

Nice blog, I plan to link to it from mine. (blog.colinurban.com)
