Part 2: Issues in Sustainable Development

Energy 

SummaryEnergy

Energy plays an important role in human development. Traditional woodfuel and fossil fuels both have negative consequences for the environment and for human health. Alternative energy technologies using renewable sources such as wind and solar energy are a more sustainable solution, but require high investment and need further development to increase efficiency.

Main Idea

Key Concepts

      • Environmental costs of fossil fuels
      • Alternative energy sources
      • Biofuel
      • Firewood problem
      • Health consequences of indoor air pollution

Outcomes

Knowledge of
