The Philadelphia Energy Authority is seeking suggestions on renewable-energy projects that might be developed as part of the Philadelphia Energy Campaign, a 10-year initiative launched in February to build clean-energy projects in city buildings, schools, low-income housing, and small businesses.

The authority says the ideas it receives in response to its "Request for Information" will help it and the city's Office of Sustainability to prepare future projects.

The request was posted on the city's website Nov. 23, and responses are due Jan. 5.
