Avoided External Cost for different Wind Deployment Scenarios in the EU27 Member States in 2030

In this section wind deployment scenarios for the year 2030 are addressed (exactly the same exercise is conducted like in section

Avoided Emissions and External Cost for different Wind Deployment Scenarios in the EU27 Member States in 2020 for the year 2020). For clarity reasons, empirical results are presented for EWEA's 2030 High Wind Scenario only, since this is the most optimistic assumption at present.

 

Before presenting the avoided external costs due to wind generation in EWEA's 2030 High Wind Scenario, annual wind generation of EWEA's three wind generation scenarios on EU Member States level in 2030 is shown in Figure 5.23.

Environmental Benefits of Wind Energy - Concluding Remarks

Empirical analyses in previous sections impressively demonstrate that there exist significant environmental benefits of wind generation compared to conventional electricity generation in the EU27 Member States.

In 2007, total annual wind generation of 118.7 TWh/yr on EU27 Member States level has already avoided 70,412 kt/yr of CO2, 183.7 kt/yr of SO2, 135.3 kt/yr of NOx and, most important, an amount of €m2007 10,216 on external cost of fossil-fuel based electricity generation (see Table 5.1). The countries mainly contributing to these 2007 results in the EU Member States are Germany, Spain, Denmark, and UK.

Table 5.1. Empirical results on avoided emissions and external cost due to wind generation in the EU27 Member States in 2007.

In the next decade until 2020 the share of wind generation will increase considerably in the European power plant mix (compared to the year 2007). Moreover, mainly due to offshore wind deployment (but also a continual increase of onshore wind), the amount of fossil-fuel based electricity generation replaced by wind generation will increase further in several of the three wind deployment scenarios analysed (see Figure 5.2).

Table 5.2. Empirical results on avoided emissions and external cost due to wind generation in the different wind deployment scenarios in the EU27 Member States in 2020.

On aggregated EU27 Member States level, the following amounts on emissions and external cost are avoided due to wind generation in the different wind deployment scenarios:

  • Reference Scenario (477.4 TWh/yr): Avoided Emissions: CO2: 217,236 kt/yr, SO2: 379.1 kt/yr, NOx: 313.5 kt/yr; Avoided External Cost: €m2007 32,913;
  • High Scenario (554.0 TWh/yr): Avoided Emissions: CO2: 252,550 kt/yr, SO2: 442.0 kt/yr, NOx: 364.8 kt/yr; Avoided External Cost: €m2007 38,284;
  • Low Scenario (360.3 TWh/yr): Avoided Emissions: CO2: 165,365 kt/yr, SO2: 299.7 kt/yr, NOx: 240.8 kt/yr; Avoided External Cost: €m2007 25,237;

Finally, in the high wind deployment scenario for the year 2030 (1,103.8 TWh/yr; see Table 5.3), the estimates on the environmental benefits of wind generation (compared to fossil-fuel based electricity generation) are in terms of avoided emissions: CO2: 459,422 kt/yr, SO2: 709.8 kt/yr, NOx: 646.4 kt/yr, and in terms of avoided external cost: €m2007 69,180.

Table 5.3. Empirical results on avoided emissions and external cost due to wind generation in the high wind deployment scenario in the EU27 Member States in 2030.

The analyses and results presented above impressively underpin the importance to further significantly increase the share of wind deployment (onshore and offshore) in the EU27 Member States in the next decades. A precondition for the full implementation of the environmental benefits estimated in this study, however, expects both continuous adaption of financial support instruments and the removal of several barriers for market integration of wind energy.
