Three South Houston High seniors last week participated in the Energy City of the Future/2050 competition, an event organized by Harris County Department of Education's Cooperative for After-School Enrichment. 
  Students created a scale model of an energy-efficient city of Houston and also a PowerPoint presentation to market their design. 
  The competition was sponsored by Consumer Energy Alliance and supported with in-kind contributions from Houston Community College, Northeast Campus Energy Institute and the Greater Houston Partnership.
