Besides the well-documented ecological harm that fossil fuels inflict, they have another drawback: our planet is running out of them. What will we use in their place to heat our homes, power our vehicles, and light our cities? This program studies the problem of energy resource depletion and explores potential solutions appearing around the world. Graphically illustrating the "deadlines" at which coal, oil, and natural gas supplies are expected to vanish, the video then examines advances in wind, geothermal, and solar power technologies-presenting the pros and cons of each. Real-world examples in Australia, England, Kenya, and other countries are shown. Hydroelectric and nuclear power sources are also discussed.
