In Minnesota, the wind is blowing but turbines aren’t turning. The machines, bought used from California and installed last fall, are completely frozen in place. Even on the windiest days, the blades sit at a standstill, producing no power. Why should anyone care? The problem highlights some of the less intuitive challenges associated with wind power — long considered to be the most feasible and cost effective source of renewable energy.
The likely culprit in Minnesota: frozen hydraulic fluid, unfit for the state’s brutally cold winters. As the temperature continues to drop, these fluids have started to thicken, turning into jelly. This is a big problem, considering how much the Midwest has spent on trying to become the U.S.’s wind power corridor. Wind power is already intermittent — the wind isn’t blowing at gale speeds all the time. But being knocked out of commission for an entire season? That could be a deal breaker.

How is this little helicopter going to unfreeze thousands of wind turbines?

En het vattenstråle smälter snabbt bort is från rotorblad. Den nya metoden är en av flera innovationer som ska säkra elproduktionen i vintriga vindkraftsparker.
Nedisade rotorblad är ett gissel för vindkraftsägare i kallt klimat. Alpine Helicopter i Boden har utvecklat ett nytt sätt att snabbt få i gång produktionen när isen tvingar snurror att stanna: en helikopter som sprutar varmvatten.
– Det tar oss ungefär 1,5 timme att behandla ett kraftigt nedisat vindkraftverk, säger vd Mats Widgren.
We are explaining our money system to our grandson, James, now 14 months old…
His mother tries to get him to go to bed at 9 p.m. But the little boy’s internal clock is still on Baltimore time; it tells him it is much too early to go to sleep.
Grandpa takes over, drawing out the monetary system like a general spreading a map on a field table. “Here is the enemy,” he says gravely. “They have us completely surrounded. We’re doomed.”
James grumbles. He squirms. He has a sunny, optimistic temperament. But we think our explanations are sinking in.
A high-ranking Iraqi military official says nearly a dozen Daesh Takfiri terrorists were killed when Iraqi Air Force fighter jets bombarded their positions in the country’s eastern province of Diyala near the border with Iran.

The year 2017 has witnessed numerous brutal conflicts, devastating natural disasters and a surge of nationalism. On the eve of 2018, UN Secretary General Antonio Guterres is urging the world to unite in order to reverse the daunting course of events.
The Secretary General started his annual New Year message to the international community by saying that unlike the previous year’s appeal, this time he is issuing “a red alert,” as the scale of the threat facing the world is unprecedented.
