TROPICAL DEFORESTATION(ABOUT 15% OF GHG EMISSIONS)

Beef Cattle Grazing Logging/Paper Soybean production (food/animal feed)

AMAZON: droughts/wildfires in 2005/6: more CO2 than 10yrs

of sequestering

SAVE THE RAINFOREST!

Climate Change Science U.S. NATIONAL ACADEMY OF SCIENCES:A strong, credible body of scientific evidence shows

that climate change is occurring, is CAUSED LARGELY BY HUMAN ACTIVITIES, and POSES SIGNIFICANT RISKS FOR A BROAD RANGE

OF HUMAN AND NATURAL SYSTEMS

97% OF RESEARCH CLIMATE SCIENTISTS SURVEYED SAID HUMANS ARE CAUSING

HIGHEST PRIORITY: STOP BURNING COAL

REPLACE WITH CHP AND NATURAL GAS

FRACKING

CLEAN COAL??? WHEN???

REDUCE NON-CO2 GHG’S(OFTEN MORE EASILY REDUCED THAN CO2)

METHANE Landfills

• Recycle• Compost• Methane capture

Meat production Eat less beef!

REDUCE TROPICAL DEFORESTATION“Save the Rainforest”

SOOT From cooking, waste burning, forest fires, diesel engines, ocean ships

AUTOMOBILE FUEL ALTERNATIVES??

Canadian Tar Sands—low net energy, high pollution, high CO2

Hydrogen Car NOT an energy source, 30 X

more costly Not within 20 yrs, maybe never;

need fuel cell breakthroughs High pollution if made from coal Clean and renewable if made

from solar/wind

Biofuels—Ethanol, Biodiesel

SUSTAINABLE BIOFUELS Substantial reductions in

CO2 emissions Use plant/agricultural

Wastes or algae grown in eutrophic water

Minimal competition with food production Uses sustainable

agriculture, preserves soil

SUSTAINABLE ELECTRICITYEnergy Efficiency

and Conservation Cogeneration--

Combined heat and power—80 GW

Biomass—Agricultural and municipal wastes, wood

WindSolar—local and

utility scale Geothermal

Ocean Energy—Tidal, Waves

EFFICIENCY/CONSERVATIONTHE GREENEST ENERGY

Saves money Lowers trade deficit and increases national

security Increase in jobs (particularly local jobs)

Energy Efficient Lights CFL LED

HANDOUT ON RESIDENTIAL ENERGY EFFICIENCY

Hot Water: Low-flow Showerhead, Solar

Electronics/Computers/Cable Boxes: turn off when not used

Energy-efficient Appliances:

1. FRONT-LOADING CLOTHES WASHER2. REFRIGERATOR3. DISHWASHER

Reduce Air Conditioning by 50%

SMALL, HIGH-EFFICIENCY (SEER 16) AIR CONDITIONER White Reflective Roof or Radiant Barrier More Insulation and weather-stripping Plug Duct Leaks A.C Thermostat up 1oF (saves ~5%) Ceiling Fans (particularly in bedrooms)

WIND ENERGY

Increasing almost 30%/yr for last two decades, very large potential

World: 240,000MW, most in Europe, China, and U.S. (Texas, Mid-west)

Major advances in Carbon-fiber blades,Variable speed turbines, Tubular towers

Low Environmental Impacts (birds, aesthetics) Renewable and NO CO2 Costs: 6-10c/kwh, boon to

ranchers

IMPACT ON HURRICANES

IMPACTS ON AGRICULTURE

Longer growing season in cold areas

More frequent heavy down-pours

More intense droughts, heat waves
