On Saturday and Sunday, area companies and organizations focused on sustaining "green" living will showcase their wares at the third annual Live Green Connecticut! festival at Taylor Farm Park in Norwalk.

The event, organized by the nonprofit Live Green Connecticut!, will feature companies from around the state -- 125 exhibitors presenting their green technologies and demonstrating their commitment to sustainability.

Live Green Connecticut! will also present an array of electric car models, including the Ford Focus Electric, C-MAX Hybrid and the Tesla Model S, available for test drive at the festival.

Ken Edwards, a Greenwich real estate broker, will showcase his own Tesla Roadster, a vehicle he purchased in 2009 fueled entirely by the electricity generated from the solar panels on the roof of his home.

"It has a zero carbon footprint," Edwards said of the car. "People are just excited and amazed at the performance, the styling, and the way it charges (using solar energy)."

Scot Weicker, co-founder of Live Green, said the festival is also about making the idea of green technology fun for the community. The event also offers a range of child-friendly activities and is expected to draw more than 1,000 spectators each day, Weicker said.

This year's festival features more participants than in previous years, many of whom approached Live Green to request inclusion, Weicker said.

"This isn't a Norwalk event, it's a Fairfield County and Connecticut event. We've had a number of companies that have said, `How do I become a part of this?' because we're the only event of this kind in Connecticut."

Renewable Resources Inc., a Stamford solar energy provider, will participate in the event for the first time this year. The U.K.-based company opened its Connecticut office in May. Five representatives from Renewable Resources' sales and installation teams will be on hand to provide information about the benefits of solar energy, said office manager Kathleen Kessler.

"Since we're a new company, we're hoping to get our name out there and educate people about solar, showing that it's cost effective and increases the value of your home," she said.

Cost savings are often a significant factor in attracting people's interest, Edwards said. In addition to owning a Tesla vehicle, Edwards is the exclusive Fairfield County dealer for ProGreen, another product that will be featured.

ProGreen is a synthetic turf brand, often used in putting greens, tennis courts and residential lawns, that aims to eliminate the environmental and financial costs of maintaining grass.

"Green is also the color of money," Edwards said. "Everyone wants to save money, so that's definitely a draw for people. But beyond that, we all share this planet, and it's the only one we have."
