Power Supplier = Power Tower

Power Towers a solar furnace using the focused sunlight large area of flat, moveable mirrors based on where the sun is by 2020 power from a Power Tower could cost 5.47 cents per kWh

Power Tower Facts Advantages cost efficient cleaner than other options easy implementation Disadvantages many panels needed expensive to set up a lot of space is required many think they are not that attractive

Rain Barrels Used for collecting precipitation from runoff for freshwater Cost around $100 to $4,000 Cost efficient and eco-friendly

Green Roof

a roof with a layer of self sustaining sod collects and absorbs rain water, provides insulation for the home creates a habitat for animals costs $15 to $20/square foot very low maintenance cost reduces air pollution reduces runoff damage

Passive Solar Technology

windows/panels that trap the sun rays and turn them into usable heat applied to eating and cooling, - water treatment, cooking solar Little to no cost to maintain must be south facing

Recycled Siding

Recycled siding is used for the insulation of a home to make it more energy efficient anywhere from $2 to $11 per square foot depending on which materials are used It is durable and requires very little maintenance Just as nice as synthetic siding, yet more cost efficient

Dual Flush Toilets Most likely look similar to this

Dual Flush Toilets has two buttons control how much water is used based on how much is excreted small flush for #1 uses 0.8 gallons large flush for #2 uses 1.6 gallons saves average 4,000 gallons Costs about $250

Straw Insulation much cheaper than normal insulation more fire resistant (burns at a lower temp.) more compact Better insulator than synthetic materials

Earth Tubes underground heating and cooling system cost about $20,000 sustainable and non-electric passive geothermal Pre heats/cools the fresh air intake

Sun Awning Used to cover the passive solar heating systems in the summer Can open and close based on the weather and heat intake retractable ~ $1,500
