This will be accomplished through the use of alternative energy sources and conservation, and the results will be independently verified. The benefit to our community will be a cleaner environment and a reduction in the operational costs of the school district, while providing a valuable learning experience for our students.Baseline DataMeasurementCurrent Amount2015-16 GoalNatural Gas Consumption (Decatherms)420,913210,456Electricity Consumption (Kwhs)5,984,8882,972,444Greenhouse Gas Emissions (CO2e Metric Tons)6,1603,080Alternative Energy Options ReviewedWind Turbines

Solar Energy

Geothermal Heating/Cooling

Hydrogen Fuel CellWind Turbines Description1 or more 900kw towers (approximately 330+ feet high)Each tower would be expected to generate 2mw of electricity annuallyElectricity generated would be metered up to the utility grid and credited against our accounts

Wind Turbines Campus ApplicationsNorthwood and Village campuses have best locations for distances from school and residential areasPreliminary feasibility study was positive a full feasibility study at a cost of $65,000 to cover both potential campus locations is recommendedWind Turbines Pros and ConsProsClean, renewable energyInsulates District from price fluctuationsLong useful life of investmentSignificant contribution towards meeting goals of reduced commercial energy usage and carbon footprint reductionAble to extend energy produced to all campusesConsSignificant upfront cost (about $2.5 million) to install turbineSize may generate adverse public reactionCould have adverse impact on Hilton Municipal Electric programSED has not determined if wind turbines will be eligible for building aid

Solar Energy DescriptionSolar arrays that are ballasted to the roofProduce electricity, as well as enable hydronic heating for hot water suppliesDoes not require cloud free skies to work, but do produce greater output under sunny skies

Solar Energy Campus ApplicationsRooftop array is best suited for installation concurrently with a new roof.

Village Elementary and Quest were identified as in need of new roofs in the Building Condition SurveySolar Energy Pros and ConsClean, renewable energy sourceReduces use of commercially produced electricity and production of greenhouse gassesCould be effective in a small application to support returning to cafeteria traysProne to diminished effectiveness during periods of cloud cover, or when receptors are covered with snowHigh cost and frequency of maintenancePossible issues with load bearing capacities of roofsGeothermal DescriptionWater is circulated through a closed-loop system to exchange energy with the earthA heat pump is used to circulate the temperate air, reducing the amount of heating/cooling required to maintain comfortable interior temperatures

Geothermal Campus ApplicationsRetrofitting a building requires installation of underground pipes, installation of heat pump, and replacement of interior heating/cooling distribution systemMost cost-effective when done in conjunction with a boiler replacement and when air conditioning is desiredThe High School is most likely to require a boiler replacement, and has a suitable surrounding campus for underground piping, with Merton Williams, Quest and Northwood also having some potential applicationsHydrogen Fuel Cell - DescriptionElectricity is generated using a hydrogen fuel rodGenerated electricity is used by the facility, with commercial electricity supplementing in periods of peak demand

Hydrogen Fuel Cell Pros and ConsClean, renewable energy sourceReduces use of commercially produced electricity and production of greenhouse gassesHigh cost of installationVery short (5 7 year) life of fuel rod, with high ($500,000) replacement costSignificant annual maintenance costs and time, including annual 1-2 week shutdownAlternative Energy Evaluation CriteriaCompatibility with Infrastructure NeedsContribution to Meeting Commercially Produced Energy Consumption Reduction GoalContribution to Meeting Carbon Footprint Reduction GoalReliabilityMaintenance and Staffing Requirements
