Grow lights

Grow lights

So i was thinking about planting some sage this year to dry and burn, but i found out that it dosent grow in zone 5 (i think). i have a spare room and i was thinking about trying to grow some in there using a grow light. however, i was wondering if anyone knows how much they cost to run? Are there even energy efficent ones on the market? Thanks!
