2. Electricity consumption 1992-2012: explosion of the demand
Back in the 80s, the overall energy consumption was low, at less than 50TeraWatt-hour (TW-h), but it has constantly risen since then.
The first three nuclear plants in Taiwan were completed in the 80’s, and since then their production has been constant at around 4000 to 5000 TW-h. At the time, nuclear energy was providing around 26% of Taiwan’s total capacity (I couldn’t find how much of the generated total that makes). The constant rise in the demand has led to a massive increase in imports of fossil fuel, mainly coal and natural gas, which explain why today the part of nuclear in the total production of electricity has decreased to around 8% of the total capacity, and around 18% of the generated total.
The share of electricity in the overall consumption of energy has kept rising, while the demand for oil started to drop in 2008 (as can be seen in the Energy Handbook).
The part of energy used for residential purpose can be correlated to the increase in the total population as well as an ever-growing penetration of domestic appliances and 3C products. However, this increase comes at a slower pace than industry needs…
..while the significance of industry in the national production is dropping steadily. Services contribute every year more to the national output while they have less electricity needs. To me it looks like an aberration that while industry production declines in value, the amount of electricity they use keeps rising.
One thing is clear, energy needs in all categories seem to have peeked in 2007, just before the world economic crisis, and the rise in electricity demand has been slower after 2008. It is easy to correlate economic growth and consumption of energy, as you can see from the chart below.
