Energy Resources
Akopọ
Every light switched on, every journey taken and every factory running draws on an energy resource. Some of those resources, the coal, oil and gas buried over hundreds of millions of years, are being used up far faster than the Earth can ever remake them. Others, the wind, the sun, the tides and growing plants, are replenished constantly. The choice between them is shaping the climate, the economy and the politics of the whole planet.
In this lesson you will learn how fossil fuels form, how to classify energy resources as renewable or non-renewable, and how each type is used to generate power. You will weigh their benefits and limitations and explore why the demand for energy keeps climbing. Real examples, from Iceland's geothermal plants to Brazil's bioethanol fields, show these ideas at work.
