Geothermal Energy These are thermal plants 1. Steam/very hot water at the Earth’s surface. These sites are rare, and mostly exploited already. Example: “The Geysers” in California. – About 30 square miles active site. – About 1000 MW continual output.

Dry Steam and Flash Steam Requires very hot water/steam (The Geysers Model)

2. Enhanced Geothermal Systems: Got Hot Rocks? AltaRock Energy Inc. at Newberry Volcano near Bend. AltaRock Drill one hole into hot (600 degrees F) dry rock Fracture rock by injecting cold water Drill more holes about 1500 feet away Pump water down original hole and out secondary holes. Convert to steam and use flash (direct) or heat exchanger/binary systems to drive steam turbine and generate electricity. January 2015 “Simulation” tests data analysis.Simulation

Enhanced Geothermal System Utilizing Hot, Dry Bedrock

3. Binary System Water below boiling loops through a heat exchanger; second loop of low boiling point fluid flashes to gaseous state which turns turbine like steam would.

Example: U.S. Geothermal Neal Hot Springs—Harney County Binary System Utilizes hot water to boil secondary fluid with low boiling point in a heat exchanger; get “steam”; turn turbine. 23 MW Energy (perhaps enough for 26,000 homes) $136 million cost

In your home Lighting: – turn ‘em off when you leave the room

In your home Lighting: – turn ‘em off when you leave the room – replace all lights with LED fixtures

In your home Lighting: – turn ‘em off when you leave the room – replace all lights with LED fixtures Energy Trust of Oregon “Energy Saver Kits”Energy Saver Kits LEDs reduce lighting energy by 85% or more Pick a “temperature” from soft to bright white Take them with you when you move—they last forever The price is plummeting—down to $3 or so

In your home Hot Water: – Set water heater temperature at 120 degrees

In your home Hot Water: – Set water heater temperature at 120 degrees – Wash clothes in cold water

In your home Hot Water: – Set temperature at 120 degrees – Wash clothes in cold water – Heat Pump Water HeatersHeaters My old 50 gallon electric water heater estimated a yearly cost of $456. My new 50 gallon HP electric water heater estimated a yearly cost of $155--a 2/3rds savings. Cost new $700-$800 – Deduct State Tax Credit of $600.Credit – Deduct Federal Tax Credit of $300Credit

In your home Ductless Heat Pump Space HeatersHeaters (usually room specific) (“Mini-Splits” best option for most) System costs $5000 and up. Saves around 50% on space heating costs State Tax Credits of $800 and upCredits Energy Trust of Oregon cash of $800 (limitations)Oregon Federal Tax Credit up to $500Credit

In your home Unplug electronic crap (or use a power strip). Turning them off doesn’t really turn them off) – TiVos and Play Station Consoles are essentially computers, monitoring all the time. But unlike “real computers” and peripherals, they don’t have the “sleep” or “hibernate” modes, so just churn away when not in use. – Ghost drains—each cellphone/tablet/computer charger draws energy when not in use. Multiply yours times billions and it means a very large number of kilowatts going for... for nothing.

In your home Unplug electronic crap (or use a power strip) when not in use (turning them off doesn’t really turn them off) – TiVos and Play Station Consoles – Ghost Drains—Chargers – Unplug Televisions, Stereos, DVD players or use a powerstrip. Powerstrips are a “negawatt nerd’s” best friend

Nest Labs Company sells thermostats that “learn” a house energy needs, and begins to set itself. “At its core it is a smart phone on your wall.” It is internet connected, so can be controlled remotely. It also allows devices in home to communicate with each other via internet—like CO2 detector “talking” with furnace.
