Lecture: The Gentle Art of Energy Conservation

Introduction

  • Energy conservation is not about "freezing in the dark".
  • Dependence on fossil fuels leads to acid rain, greenhouse warming, and smog.
  • Using less energy and switching to alternatives makes environmental and economic sense.

The Energy Crisis of the 1970s

  • Oil prices spiked due to Middle East politics.
  • This economic shock forced companies like Volvo to innovate.

Volvo's Light Component Project (LCP)

  • Aim: Create a car with minimal energy consumption.
  • Focus on weight reduction using lightweight materials: magnesium, aluminum, plastics.
  • Developed a highly efficient diesel engine.
  • Achieved 65 mpg, with potential for 100 mpg.
  • Only four cars were built due to dropping oil prices.

Energy Efficiency Technologies

  • Amory Lovins' Suitcase: Contains electricity-saving technologies.
    • Compact fluorescent lamps, super-insulating windows, efficient motors.
  • Economic incentive: Utilities save money by helping customers conserve energy.

Osage, Iowa: A Case Study in Energy Conservation

  • Headed by Wes Birdzall, the town cut energy use by 25%.
  • Free energy surveys, educational programs, and efficient installations.
  • Infrared images of homes encouraged residents to insulate and save energy.

Energy Use in Developing Countries

  • Example: Karnataka, India
    • Traditional cooking over open fires is inefficient and unhealthy.
    • Efficient stove designs reduce fuel use by half.

Renewable Energy and Biofuels

  • Brazil's alcohol fuel program using sugarcane.
    • Large-scale renewable fuel program to reduce oil dependency.
    • Bagasse, a byproduct, used to generate electricity.

Nuclear Power

  • Once seen as the future, now controversial.
  • New experimental reactors in Germany focus on inherent safety.

Renewable Energy in Bornholm, Denmark

  • Attempt to stop using imported oil using wind and biomass.
  • Faced challenges with taxation and economic viability.

Conclusion

  • Fossil fuels are cheap but environmentally harmful.
  • Alternatives exist but need to be economically attractive.
  • Individuals can make a difference through conservation practices.

Funding

  • Major funding for "Race to Save the Planet" by Annenberg CPB Project and others.
