• I have a nuclear with a capacity of 500MW (power). • How much energy can this power plant produce in a year? • How many hours are in a year? • 24*365= 8760 – (Q&D, +/- 10.000 minus 12%) – ≈500MW * 10.000 hours – ≈ 5.000.000MWh – ≈ 5.000GWh – ≈ 5 TWh – =4.4 TWh

• In the EU in 2012 there was a capacity of 120GW (power) in solar. This produced 100TWh in 2012. • What is approximately the capacity factor of EU solar? • How many hours are in a year? – 10.000 minus 12% • If it ran at full capacity (100% c.p.) it would have produced about 120 * 10.000GW – ≈1.200.000 GW – ≈1.200 TW – ≈1.000 TW (minus the 12%) • But it produced 10 times less… • Thus c.p. is ≈ 10%
