Welcome to APES 1/7 O – 1/8 W Welcome Back! • Look at 3 of the ads around the room from The Economist. For each of the ads do the following: • Write the number of the ad and a complete sentence summary of what the company is selling or how they are trying to portray themselves. • What topic on the topic outline is this ad from? (if you are missing your topic outline there are extras by the outside window)
2. If The Economist is looking at trends for next year, what do these ads say about the relevance of APES topics in the business world? 3. How might you be able to use your APES background to get further with your future employment goals?
Welcome to APES 1/9 O, 1/10 W Daily objective: Renewable energy – solar, solar electricity, hydrogen fuel cells, biomass (V:G) Biodigesters! Take some brief notes over the short biodigester presentation. Please turn your WS into the box.
What’s the basic energy problem in developing counties? Using natural gas for cooking, heating, and heating water requires methane be brought to people’s houses using pipes. Most developing countries, or some developed countries in rural areas, don’t have this pipe infrastructure.
What is done currently? Without methane infrastructure, people burn wood or coal in stoves (50% of the people in developing countries).
Bad because: • Many more home fires/burns • Huge indoor air pollution problem with particulates and incomplete combustion– 2 million excess deaths per year, 4% of global health burden (WHO facts)
What is a biodigester? Uses decompostion of organic wastes (specifically food and animal dung) to produce methane! $140 to install, including biodigester and pipes to home. Simple pipe from biodigester to home stove/water heater.
Biofuels on a local scale!! Reliable source of methane for home, no need for indoor wood/coal burning stove. Local production only – for one household or business.
Welcome to APES 1/13 O, 1/14 W Daily objective: Renewable energy – solar, solar electricity, hydrogen fuel cells, biomass (V:G) Look at the yellow sheet on your desk. Please copy it (INCLUDING THE QUESTIONS) into your journal, and match the type of solar with the appropriate description! Please get your pre-lab and blue rubric Out on your desk for a stamp!
Welcome to APES 1/15 O, 1/16 W Daily objective: Renewable energy – solar, solar electricity, hydrogen fuel cells, biomass (V:G) Please write down three interesting things you learned from the card sort activity about each of the following vehicle technologies: • Clean diesel • Hybrid • Electric plug-in 4. Hydrogen fuel cell
Welcome to APES 1/17 O 1/21 W Daily objective: Renewable energy – wind energy, hydroelectric, ocean waves and tidal, geothermal (V:G) Dams! Take some brief notes over the short dams/dam removal presentation. PLEASE CUT AND PASTE ALL OF THE TRADE-OFF CHARTS IN YOUR JOURNAL NOW!!
In the U.S., there are over 80,000 dams 9 ft tall or taller. • Most are small and privately owned, and used to power mills/factories – aging and obsolete • Concerns about upkeep, safety, and repermitting costs have made many liabilities
Dam Removal As the cost of maintaining older dams more than continuing to use them, so many being removed • Over 60 per year being removed, over 1,000 removed in U.S – mostly in Midwest and east • Larger dams starting to be removed out west, cost and Endangered salmon species benefits
Problems with Dams • Reduce downstream water, silt, nutrients, changing ecosystems • Fish can’t spawn, causing decline in species (55% of spawning grounds blocked by dams)
Elwha River • 2 dams removed/being removed (powered only 40% of single paper mill) • Largest ever, Glines Canyon Dam, 210 ft tall • 3 threatened/endangered fish • Formerly 400,000 salmon from 10 different species used watershed for spawning • 83% of river in protected National Park – 70 miles of salmon habitat
Glines Canyon Dam Two methods of dam removal: 1. Piece by Piece http://www.youtube.com/watch?v=mQusj6tD97w

Welcome to APES 1/27 W, 1/30 O DO: Fracking and Water Pollution • Look at the Shale-Gas Reservoir map. What is the largest reservoir in America, and what are the four in Texas? • Look at the fracking diagram. Discuss the role of water in the fracking process – specifically how much is used, what’s in it, and what’s done with it after fracking. 3. Write down three fracks from the “Fracking Song”.

Welcome to APES 1/31 W ; 2/3 O DO: Water Pollution – Acid rain • What do the Clean Water Act and the Safe Drinking Water Act regulate (be specific)? • Fill in the chart below with contaminants regulated with the SDWA (from red chart):
Welcome to APES 2/4 W, 2/5 O DO: Water Pollution – Types, sources, causes, cultural eutrophication, ground water pollution, sewage treatment, Clean Water Act 1. Look at the water samples on the front table and fill in the chart appropriately:
