With the cost of energy on the rise and climate change looming, hundreds flocked to the 2023 Green Home and Energy Show in South Portland on Saturday to learn how to reduce their use of fossil fuels and save money in the process.

Holly Tracy of Warren wanted to learn about solar panels, heat pumps and other ways to reduce her fossil fuel consumption.

Rolling her eyes in disgust, Tracy said she heats her home with oil. She keeps the thermostat set at 60 degrees and uses a wood stove, but her oil budget plan still costs $500 a month for 11 months of the year.
