Mason Crawford, a volunteer science teacher, participate in an interactive energy demonstration first graders at Logan Elementary School, Feb. 25 highlighting Balfour Beatty Communities' solar energy project scheduled for military housing units here. The school event taught pluses and minuses of energy practices and highlighted the need for sustainable energy sources. BBC and Fort Bliss have partnered with Solar City to install and maintain solar panels on military housing here that will produce approximately 25 percent of electric energy usage as part of the Army's goal to bring energy sustainability to Net Zero. Net Zero would mean that the installation is self-sustaining in electricity, water and sewage. Fort Bliss expects to meet the Net Zero goal by 2018.
