As the wind power debate grabs the Vineyard’s attention, the Martha’s Vineyard Public Charter School invites the Island community to a screening of the documentary film Coal Country at 10 a.m. Saturday, Feb. 20. Admission is free; donations to the charter school science lab project are welcome.

A production of Mari-Lynn Evans and Phyllis Geller, Coal Country reveals truths about how energy is produced. The film visits working miners, activists who are battling coal companies in Appalachia, as well as coal company officials concerned about jobs and the economy who believe they are acting responsibly in bringing power to the American people.

Guinevere Higgins, regional high school class of 1999, will make a presentation and take questions after the film.
