Why is learning about power and energy so important

How Much Energy Do You Use On A Daily Basis

Importance Air emissions Other environmental concerns Global warming Dependence on foreign fossil fuel Finite resources Economy Cost of living Cost of Business Balance Other

Why Is It Important To UVM Physical Plant Operating Budget FY05- $25.2 Million

What Are Some Of Today’s Issues here at UVM The growth on campus Energy costs Systems are outdated and obsolete Chilled water is not centralized Air conditioning is an expectation Utilities are critical for Research System reliability

What Can You Do About It Learn about various types of energy solutions Educate others In your careers try to promote energy awareness Maybe become an engineer Every little bit helps

Typical Solar Turbines Cogeneration Unit

Conventional Electrical Generation Pollution (Remote from Users) Power Plant 67% Waste Heat Fuel 100% 33% Electricity

Combined Heat and Power (CHP) Waste Heat & Mechanical Losses 20% Pollution Electricity Fuel 100% 80% Steam Chilled Water CHP Plant

Cogeneration Benefits Better system efficiency (cost effective) Savings of millions of dollars over 20 years Protection from brown-outs Less overall emissions – Credit for LEED certification Cage plant space is compatible for a cogen installation Physically and economically viable Improves reliability

“See the Need, Take the Lead” UVM Wind Turbine Watts in the Wind @ UVM? Campus Renewable Energy Project “See the Need, Take the Lead”

Project Specifics Modest reduction in campus CO2 output by 3,500 to 5,900 lbs. per year because of the wind turbine. Due to location specifics, it is estimated that the turbine will generate 3,000 to 5,000 kilowatt-hours which is enough to power an new, energy efficient home for 12 months. The data logger, at the base of the tower, will collect data on wind speed, wind direction and kilowatts produced.

What is tidal energy? Tidal energy is one of the oldest forms of energy used by humans. Indeed, tide mills, in use on the Spanish, French and British coasts, date back to 787 A.D.. Tide mills consisted of a storage pond, filled by the incoming (flood) tide through a sluice and emptied during the outgoing (ebb) tide through a water wheel. The tides turned waterwheels, producing mechanical power to mill grain. We even have one remaining in New York- which worked well into the 20th century. http://www.oceanenergycouncil.com/faqtidal.html
