As indicated in the Jens Christiansen graphic above, Denmark’s net imports exceeded 80% of demand several times in July. Per Jens, a Danish physicist, “this is the downside of being a wind leader we have to talk about.”

As previously noted, these power generation realities cannot be ignored:

  • Wind and solar power are intermittent, such that demand must respond to variable supply (not a prescription for economic growth).
  • Assuming sufficient capacity, gas power plants respond to variable demand.
  • Power grids can function effectively with only natural gas, but not with only wind/solar.
  • Integrated wind, solar, and gas systems can reduce, but not eliminate, demand for gas-generated power.

This graphic by Australian Cliff Hall explains the importance of “dispatchable” power. Of course, imported electricity, on which wind-leader Denmark relies heavily, is an alternative to dispatchable power. However, that option is less than optimal from economic growth and energy security standpoints.
