Info

Heating oil has generally been displaced from electricity generation, on account of its high costs. Its use in our power stations is virtually restricted to starting-up. Ecological Review – Facts and Details The ecological review comprises input and output data in the energy sector for the past two years and includes information from the indus- trial and service divisions (exception: Salamander) in their capacity as primary operators for the entire group within that sector. The input/output in the waste treatment division can be seen in the chart on page 64.
