Energy Management

Energy security means having a reliable, uninterrupted and affordable supply of energy. A country's energy security depends on the supplies available, the size of the population, and the amount of energy a typical person uses. Global energy production and consumption are unevenly distributed, and energy insecurity can lead to a range of environmental, economic and social impacts.

1) Energy security means having a reliable, uninterrupted and affordable supply of energy. 2) A country's energy security depends on the supplies available (either produced or imported), the size of the population, and the amount of energy that a typical person uses. 3) An energy surplus is when a country produces more energy than its population requires — the extra energy can be exported. An energy surplus gives a country energy security. 4) Having less energy than required is called an energy deficit — this can cause energy insecurity.

Exam Tips

  • Learn the advantages AND disadvantages of each renewable energy source — exam questions often ask you to evaluate or discuss.
  • Know the fracking debate well — it's a hot topic and examiners love to test it. Learn specific facts (2.9 magnitude earthquake, Lancashire, 1 trillion m3 of gas).
  • For the Bihar case study, remember specific statistics: 84 plants, 200,000 people, 85% not connected to grid, 1.5 km range.
  • Understand the difference between direct emissions (heating, driving) and indirect emissions (manufacturing goods you buy).
  • Remember that energy consumption correlates with wealth — be able to give specific country examples for both high and low consumption.
