Vestas by the numbers
Better use of energy
Vestas has a policy to purchase renewable electricity where available. By procuring renewable electricity and in collaboration with suppliers and authorities, Vestas seeks to ensure better access to renewable electricity. To meet Vestas' WindMade commitment and renewable energy goals, a wind power plant has been established internally to balance out electricity bought in countries where Vestas is not able to buy renewable electricity.
For 2012Q1, the share of renewable energy was 44 per cent and the share of renewable electricity was 89 per cent. The corresponding figures for 2011Q1 were 31 per cent and 70 per cent. The increase in share of renewables is mainly due to production from Vestas’ own wind turbines. Vestas has in 2011 started building wind turbines for in-house use in order to balance the energy consumption for locations were local renewable electricity purchase is not possible. In some cases, Vestas may also in this connection act as co-investor in customer projects. Vestas is currently involved in a couple of projects under construction in Eastern Europe.
On average over the last four quarters, Vestas facilities worldwide used about the same amount of energy to produce a wind turbine as last quarter's average.
The graph shows how much energy, measured in megawatt hours, is needed to produce a wind turbine with the capacity to generate 1 megawatt per hour. In 2009, for example, the average was about 88 MWh/MW, meaning the wind turbines had to run at full speed for 88 hours to produce enough energy to make up for Vestas' production.
On average over the last four quarters, Vestas facilities worldwide succeeded in drawing more of their energy from renewable sources. The company's renewable energy use worldwide was 41.5 percent, up from last quarter's average of 37.9 percent
Vestas facilities worldwide also succeeded in using more renewable electricity. The company's average renewable electricity use worldwide over the last four quarters was 72.9 percent, up from last quarter's average of 67.9 percent
The graphs show the proportion of energy and electricity that come from renewable sources.
Vestas facilities worldwide increased their total average energy consumption by 8.5 percent over the last four quarters compared to the average from a quarter before.
The chart shows how much of each different type of energy -- electricity, district heating, gas, fuel and oil -- that Vestas factories worldwide used in production last quarter.
A note about the numbers: In most cases, the numbers presented here are based on either annual or four-quarter rolling averages. For example, the total displayed for the second quarter of 2010 actually represents an average of that quarter and the three quarters before it. This is done to smooth out seasonal variations in production and supply, to more accurately show trends in resource use at Vestas. Injuries and employment information are the only aspects not calculated on a rolling basis.
