Mass Production Economy (1830s-1970s)
Service Economy (1970s-2008)
Data Economy (2008-Present) Support needed for these economies: Clean water
Safe removal of waste
Grid to deliver power
Green power for sustainability Past Present Future Brought to you by the Gang of Forty:

Working for improvements in the workplace Watershed
Transfered (pressurized and piped) For survival, bathing, cooking, and laundry Water from baths, toilets, and kitchens
Cleaned before released into environment Waste treatment facilities do in 9 hours
what it takes nature 9 months. Contact points for solving customer issues, billing, starting service, and repairs. Revenues for this industry were expected to reach ~$26 billion in 2009* Provides public lighting along paths and roadways.
Increases safety and use of public/private spaces. There are over 242,000 streetlights in
Los Angeles alone. Frost & Sullivan, in a report entitled North American Outsourced Contact Center Services Market, Utilities are becoming more efficient by reusing steam used to turn a turbine to also heat buildings. Electricity that is generated by turbines is then delivered using the national grid. It is not stored. There is over 300,000 km of power lines in the U.S. Solar energy can be used to actively generate electricity similar to fossil fuels
It can be used passively to warm rooms or water to reduce heating costs The price of solar panels has dropped over 200% in the last 30 years.
Unlike fossil fuels solar energy will not run out in the near future and does not produce harmful air pollutants. Wind turns the turbine directly, generating electricity. The typical industrial windmill stands 20 stories tall. U.S. windmills produced enough energy in 2008 to power 7 million homes.
Wind is a renewable non-polluting resource that requires little cost after the initial investment. http://www.nexteraenergyresources.com/content/where/portfolio/wind/facts.shtml Uses steam from the heated water in the earth to turn a turbine
Because the earth is a relatively constant temperature approximately 6 feet down, geothermal exchange units can buffer extremes in temperature by running water through the ground.
Geothermal exchange units save homeowners 30-70% in heating and 20-50% in cooling compared to conventional systems.
There are over 1 million of these units in the U.S.
The environmental benefit is the same as if you planted 385 million trees. Carbon composite

forecasting Satellite solar
power A new building material for the frames of cars
that will be able to store energy to be used later. Small devices are able to be powered using a microwave transmitter.
A sensor attached to the device picks up the microwaves with an antenna and converts the signals to electric energy. Uses modeling to project peak demand for energy use
Used for conservation measures The newest form of solar power is in use of satellites.
Satellites serve as a dam that catches energy from the sun and pumps it to the earth via a microwave beam. Advances in energy storage are changing the face of utilities.
MIT engineers can genetically engineer viruses to build the positive and negative charge ends of a lithium-ion battery. Water can be turned to steam to directly heat buildings or to turn a turbine to create electricity. Heating water to steam can be done with nuclear, oil, gas, wood, etc. Nuclear fission reactors break apart atoms and use the heat that is released to boil water to steam that turns a turbine to generate electricity. Nuclear power plants produce no controlled air pollutants or greenhouse gases. These fossil fuels can be used to directly generate heat for cooking and warmth or generate electricity by heating steam that turns a turbine 85% of the electricity in the U.S. is generated by oil, gas, and coal.
