The document discusses predictions about future energy sources and consumption of oil reserves, noting that predictions from the 1970s of oil being depleted by the early 21st century were exaggerated but that at current consumption rates oil resources will be used up within 100 years. It also outlines developments in alternative energy sources like biodiesel, solar, electricity, and hydrogen and predictions that half of vehicles will run partially on electricity and gasoline by 2024 and all new US cars will use hydrogen by 2038.

- 15. Reporter : Professor, in the nineteen seventies, scientists predicted that the world's oil reserves would have all been use up by the beginning of the twenty-first century. Prof. K : Those prediction were highly exaggerated. However, in a hundred years' time at the present rate of consumption, we will have use all the available oil resource. Therefore, we need to find clean renewable fuel, especially for automobiles.
- 16. Reporter : What other fuels are being developed? Prof. K : We are working on alternative sources of energy such as biodiesel, solar energy, electricity, and hydrogen. Reporter : What will we be filling our car tanks with in twenty years' time? Prof K : According to the U.S. National Engineering Academy, by 2024, half of all vehicles will be running on part electricity and part of gasoline. They also predict that by 2038, all the new cars produced in the U.S. will use hydrogen.
- 17. Reporter : That's a big change in relatively short period of time? Prof. K : Yes, science nowadays advances very quickly, and changes in technology that affect people's every day lives can occur very fast. I wouldn't be surprised if most of us will be driving hydrogen-powered cars in the near future.
