Green Technology Movement and Impact on Global
Environment
COMM 12
Fall 2007Erica Eaton, Page Nichols, Kate Devlin

What is Green Technology?
Environmental technology or “green technology” is the application of the environmental sciences to conserve the natural environment and resources, and by curbing the negative impacts on human involvement
3
The 7 R’s of Green Technology:
4
Who is involved in the Green Technology Movement?
With rising energy costs and the threat of global warming, any businesses are now recognizing the benefits of using technology to reduce their carbon footprint and minimize waste
Go to: http://www.earthday.net/footprint/index.asp# and see what your carbon footprint is.
5
…continued who is involved
As “Green” becomes trendy, businesses benefit from becoming part of the movement
“Green” products sell = overall revenue increases
THE EXPERTS! Those most familiar with the material who can teach the technologies to push for a greener world
6
Why are companies choosing to go Green?
Because people are requesting environmental technologies
Example: hybrid versus non-hybrid most people want the hybrid for a variety of reasons
Green is a trend that is going to be around for a while. It will stay important as long as climate change is an issue
7
…continued why companies are going Green:
Companies benefit from going Green because:
• a) it’s a trend so it sells• b) although the cost of going
green may be high, the cost of staying green is significantly cheaper in the long run
8
How are companies going Green?
By working with experts who know the material wellUsing sustainable building plansImplementing restrictions on waste
• -example: Wal-Mart has been aggressively pursuing a variety of environmentally friendly strategies over the past few years. The impact on the retailer and it’s suppliers could be significant. Wal-Mart suppliers are required to meet certain waste standards.
9
GREEN SYNDICALISM“green syndicalists have understood that labor struggles and ecological struggles are not separate.”
Definition: a radical political movement that advocates bringing industry and government under the control of federations of labor unions by the use of direction such as general strikes and sabotage.
10
…continued SyndicalismGreen syndicalists insist that overcoming ecological devastation depends on shared responsibilities towards developing convivial ways of living in which relationships of affinity, both within our own species and with other species, are nurtured.
11
GREEN BUILDINGGreen Building is the practice of increasing the efficiency of buildings and their use of energy, water and materials and reducing building impacts on human health and the environment through better citing, design, construction, operation, maintenance and removal - the complete building life cycle.
12
Daily Water Waste:
Some Facts:Dishwashers use 14-18 gallons of water per cycleTop loading washers use 45 gallons per washA dripping faucet wastes 15-21 gallons of water per day
13
How people can contribute to Green Building:
Think smallHeat with the sunUse renewable energyConserve waterUse local/natural materialsRecycle materials
14
Renewable/ Alternative Energy SourcesEnergy obtained from sources that are essentially inexhaustible.
Have less of an impact on the environment
15
Solar PowerHeat Transfer
• oil in a pipe is heated, then runs through reservoir of water. Heat from oil causes water to boils, creating steam which turns turbines.Photovoltaic (common solar panel)
• photons from sunlight knock electrons into higher sates of energy causing potential voltage difference (electricity).
16
Solar PowerCIS Tower, Manchester England. Was covered in mosaic tiles, which with photovoltaic panels turned grey due to pollution. Tiles replaced, costing £5.5 million. Began feeding National Grid in 2005.
17
Water Power: Tidal Flux
Captures energy of waves in the ocean or large lakes
Repairs are more costly at sea
•
18
Water Power: Hydroelectricity
Rivers are dammed, and water is released slowly
Force of rushing water creates electricity
Environmental concerns of building dams
19
Wind
Wind rotates turbines to create electricity.
Has potential to take over all of our electricity needs (on 13% of all land area)
20
Geothermal
Pipes are routed near geothermal activity. Boiling creates steam, which turns turbines.
21
Why are businesses going green?
Saving energy = saving money
Gaining consumer confidence
Managing dependence on oil and other fuels that could spike in price, or become regulated.
22
What are businesses doing?
Wal-Mart recently began cleaning up its environmental practice, dropping customer complaints by 10%GE spent $1.5 billion on new technology to help reduce waste products and energy consumption
23
What are businesses doing?
FedEx Corp. and United Parcel Service have invested in vehicles that run at least partly on alternative fuels.
DuPont, a chemical company, was once America’s main producer of greenhouse gasses. Now, they are slowly reducing their production of carbon emissions.
24
Triple Bottom Line
Businesses are taking into account their effects on the environment.CLP Group, a Hong Kong based power plant operating company, now includes data in its annual reports such as “waste produced” and “effectiveness of environmental programs”.
25
Green Business?
Big business is a leading producer of greenhouse gasses, but according to Janet Ranagathan, the director of the World Resources Institute, businesses voluntary reducing waste and energy consumption is the fastest way to curb greenhouse gasses
Many companies claim to be “green”, while only making unsubstantial changes
26
Hybrid Vehicles
Honda Civic
Honda Accord
Ford Escape
Volkswagon
Chevy Malibu
Honda Subcompact (2009)
Hyundai Accent (2009)
Lexus GS 450h
Lexus LS 600H L
Saturn Aura Green Line

Pick-up trucks coming in December:Chevy SilveradoGMC Sierra
27
Driving Trends
Since 1770, miles increased 150% while population increased 40%
200 million vehicles in the U.S.
700 million in the world
By 2008, one million hybrid gas-electric cars in the U.S.
28
Vehicles and the Environment
1 gallon of gas weighs 6 pounds
• When burned…
Carbon + Oxygen = 20 pounds of CO2
CO2 is the dominant greenhouse gas causing global warming!
29
Connect the DotsDriving is our most air polluting activity
We spend an hour per day in the car (on average)That’s 8 BILLION hours per year collectively
3 out of 4 people drive to work alone
Families take about 10 vehicle trips per day
Less than 5% use public transportation
Health care from transportation pollution costs $60 billion per year
30
Health EffectsAutomobile pollutants have an impact on health and the environment
Respiratory problems
Impair the body’s immune system
Increase a person’s risk of cancer
Birth defects, low birth weight, infant deaths
Asthma
31
Total Impact of Green Vehicles
Smaller, lighter cars
Fewer materials
Decreases emissions
Eases environmental impact
No proven reduction in car’s safety!
32
Solar Power• * power from the sun *
33
Benefits
Reduces local air pollution
Offsets greenhouse gases
Conserves energy
Reduces the need for dry-cell battery disposal
34
The Green GridThe Green Grid is a global consortium dedicated to developing and promoting energy efficiency for data centers and information service delivery
How?
By defining user-centric models and metrics,
Developing standards , measurement methods, & new technologies to improve performance,
Promoting adoption of new energy efficient standards 34
35
Conclusion?More and more corporations are jumping on the green bandwagon.
It’s trendyIt’s important!It’s good for the environmentIt saves companies moneyIt benefits our health
