Have you ever wondered how much money it costs to keep Gardens Aglow at Botanical Gardens in Boothbay Harbor all lit up for the holidays? You would think it is very expensive to run it. After all, there are 650,000 LED lights, making it the biggest night light display in the state of Maine, and perhaps the biggest in New England.

According to people in the know at Botanical Gardens, it is surprisingly energy efficient. They posted on their Facebook page that it costs eight cents per KWh. Therefore, the total amount is only around $120 for the whole event. That's much less than what we expected.

Coastal Maine's Gardens Aglow is open now through December 31st. (Thursdays through Sundays from 4-9 p.m. Closed Christmas Eve.)
