According to this report at www.windpowermonthly.com, December was the first month that Denmark got more than 50% of its electric power for an entire month. An estimated 54.8% of the country's energy came from wind, according to the post, which said in part, “During the Christmas week, generation from wind turbines supplied 68.5% of the electricity consumed. On 1 Dec. turbines generated energy which amounted to 136% of energy used.
"High winds over the period meant that generation from wind farms was greater than normal. Low consumption due to the closure of factories over the Christmas period also contributed to the record. The Danish government has a target of generating 50% of its energy from wind by 2020.”
