Energy Resources
Bayani Gaba-gaba
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.
Manufura
- 1.4.1 Describe the formation of fossil fuels, limited to: (a) coal (b) petroleum (oil) (c) natural gas (methane).
- 1.4.2 Classify energy resources as renewable (non-finite) and non-renewable (finite), limited to: (a) renewable (non-finite): biofuels (bioethanol, biomass, biogas and wood), geothermal power, hydro-electric power, tidal power, wave power, solar power and wind power (b) non-renewable (finite): fossil fuels and nuclear power using uranium.
- 1.4.3 Describe how the energy resources in.
- 1.4.4 Discuss the benefits and limitations of the energy resources in 1.4.2.
- 1.4.5 Describe and explain the factors affecting demand for energy, limited to: (a) transport (b) personal and national wealth (c) climate (d) human population size (e) industry (f) disruption to supply (g) unreliable supply (h) scarcity of resources.
