To support the work of Tennessee's Energy Efficient Schools Initiative (EESI) Council, this report describes data on energy expenditures in school districts for 2002/03-2007/08. Energy expenditures rose from about 2.6 percent to about 3.0 percent of total expenditures over the period, with some differences in the mix of energy types and expenditures per student by district characteristics. An index of fiscal stress can be used to establish priority districts for EESI Council funding. Simulation of the impact of future energy inflation by district characteristics finds that the variation within districts grouped by characteristics is just as large as that across district characteristics, suggesting that the EESI Council should investigate individual district circumstances in allocating state funds rather than create allocation rules based on district characteristics. Appendices include: (1) Energy prices nationally and in Tennessee, 2002-08; (2) Energy and total expenditures for 106 Tennessee school districts, 2002/03-2007/08; (3) Total expenditures, energy expenditures, and operations and maintenance energy expenditures, by district, school year 2007/08; (4) Stress scores for 136 Tennessee school districts and tests for differences in the means of stress scores by district characteristics; and (5) Simulation results, by district. (Contains 1 box, 8 figures, 20 tables, and 11 notes.)
