Ben Perry, who puts together the Bluegrass GreenExpo, likes to say that this year's event promotes green living "from the day you are born until the day you are laid to rest."

That's because one of its workshops outlines actions people can take to reduce their carbon footprint as soon as they can communicate, and another deals with "green burials."

The event, which takes place this weekend in Lexington, also features booths offering information on things such as energy-efficient windows, solar energy, local foods and businesses, and more.

This is the sixth annual expo. Last year's event attracted nearly 2,400 people — a record.

The workshops have expanded this year. Perry says they fall into four main categories: energy, transportation, green homes and sustainable living. There's also a workshop on socially responsible investing.

There will be demonstrations of energy generated by waste, working demonstrations of the sun being used to generate electricity and heat water, and a locally designed and built wind turbine that is "suitable for residential use."

For the first time, there will be workshops geared for professionals, including teachers, architects, designers and people in the building industry.
