MADISON — State Rep. Ann Dorney will be hosting an energy information fair from 9 a.m. to 3 p.m. Saturday at Madison Memorial High School.

Dorney said she had the idea for the energy expo when she realized how much money was being spent on energy in her community.

“We have some of the oldest houses in the country,” said Dorney. “Many of them are not adequately insulated, which means that many of my neighbors, who are on fixed incomes, pay more towards heating costs.”

Both Efficiency Maine and Summit Natural Gas will be at the expo to discuss programs, as well as local car companies that will demonstrate their hybrid and electric cars. There will also be information available on training programs in the area for anyone looking to work in the energy field.

Informational sessions on geothermal energy, natural gas, small-scale wind power projects, solar options, government programs that help finance energy upgrades, home weatherization, biomass, calculating your carbon footprint and heat exchangers will be held.

The event is free.
