Issues and Concerns Big questions
How much longer petroleum will last? What are geopolitical, economical and the environmental
impacts?
Concerns Useful energy is being more scarce. Population increases at an exponential rate. Industrializations demands more and more energy. Environmental problems becomes more severe with increases
in energy consumption. Limited resources can impact social, cultural, and economical
aspects of our lives.
Where are we going from here?

Energy

Sources Nonrenewable
Fossil Fuel (Coal, Oil, Gas) Nuclear (Fission, Fusion) Geothermal
Renewable Solar (Thermal, Photovoltaic) Wind Waves, Tides, Hydroelectric Biomass

Why Petroleum? Oil delivers more than 15 times the energy of
an equal mass of dynamite, 700 times that of a bullet, and 100 times energy of laptop batteries
One gallon of oil does as much work as 20 workers work 10 hours a day for an entire year
It is the main ingredient for a variety of consumers products, including pharmaceutical, cosmetics, clothing, pesticides, lubricant, solvents, and ….
It is CHEAP!!!!

The Greenhouse Effect

And if all that is not enough…
21
Ignoring it doesn’t make the problem go away
22
Environmental Consequences (Fossil Fuels)
Global warming Ozone depletion Acid rain Poisons
23
Major Air Pollutants
24
Carbon Footprint
25
Average American household produces 150 pounds of CO2 a day We can easily reduce it by half.
Pounds of Carbon Dioxide
One Gallon of Gasoline 19.6
100 cubic feet of natural gas 12
One ton of coal 1.4-2.8
One kWh of electricity 1.5
Environmental Consequences (Nuclear)
Nuclear Waste (NIMBY) Nuclear Accidents Nuclear War Terrorism
26
Environmental Consequences (Renewable)
Solar Wind Wave, Hydropower Biomass Geothermal
27
Ozone Depletion One chlorine or bromine
molecule can destroy 100,000 ozone molecules, causing ozone to disappear much faster than nature can replace it.
28
Acid Rain Only a few marine
species can survive when pH is smaller than 5.
Health effects include respiratory complications, reduced immunity to infection, reduced visibility, and corrosion.
Regional conflicts (US, Canada, Europe)
29
Indoor Air Pollution Average person stays 90% of his time indoors Energy conservancy projects have exacerbated this problem Common sources of indoor air pollution are:
Cigarette and tobacco smoke Paints, lead and other construction material Stoves, refrigerators and other appliances cleaners and chemicals Pesticides Soil Drinking Water

Future Transportations

Summary Energy will remain the most critical
issue affecting the globe in the 21st century. Energy Efficiency Alternative Resources Jobs Environmental Impacts
