(NECN) - Usually houses full of marijuana plants are getting busted -- not being hailed for their energy efficiency.
But in North Carolina, that is the case for a house that was built out of hemp.
It's reportedly the first ever "hemp house" permitted to be built in the U.S. The owners say last month's cooling bill for the 3400 square foot home was only about $100.
That's because of the thermal capabilities of hemp. The couple also says it only cost $133 per square foot to build the house, using industrial 'hempcrete.'
They say they wanted to use recyclable materials that are healthy and better for the environment.
