tricity trade, fuel consumption and NO X emission are illustrated and compared in<br />

Figure 3A-4. In 1990 <strong>the</strong> Danish electricity import was large causing relatively low<br />

fuel consumption, whereas <strong>the</strong> fuel consumption was high in 1996 due to a large<br />

electricity export. In 2003 <strong>the</strong> net electricity export was 30760 TJ which is much higher<br />

than in 2002. The high electricity export in 2003 is a result of low rainfall in Norway<br />

and Sweden causing insufficient hydropower production in both countries.<br />

To be able to follow <strong>the</strong> national energy consumption as well as for statistical and<br />

reporting purposes, <strong>the</strong> Danish Energy Authority produces a correction of <strong>the</strong> actual<br />

fuel consumption without random variations in electricity imports/exports and ambient<br />

temperature. This fuel consumption trend is also illustrated in Figure 3A-4. The<br />

corrections are included here to explain <strong>the</strong> fluctuations in <strong>the</strong> emission time-series.<br />
