Water: our most valued resourceEach kWh generated from coal
requires up to 27 gallons of water produce
X 11,502,861,000 kilowatt hours*
310,577,247,000 gallons of water per year*
*Residential, commercial and industrial use of electricity produced from coal in 2002For Massachusetts alone.
Carbon dioxide & Higher Temperatures Increased water & air temps
Melting of polar ice
Rise in sea level Change in precipitation
patterns & extreme weather events
Pests & disease migration
Species migration
Species decline
Change in ground water supplies

producing electricity from coal
Destroys mountain topsLocal ecology
Destroys communitiesThreatens public health
by polluting: Water

No air emissions
No fuel to mine, transport or store
No cooling water use
No water pollution
No wastes (hazardous, toxic, radioactive, etc)
Wind Power’s Environmental Benefits
Solutions:
•Conservation in tandem with renewables
•Diversity of resources•Live locally

committed citizens can change the world. Indeed, it is the only thing
that ever has.”
