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 FactsAdvantages

• 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

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

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• 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
