What are the red blinking lights in Texas?

The blinking red lights mark the country's new behemoths—wind power turbines.

Why do windmills light up at night?

The lights always blink briefly every night as a test to ensure that nothing is malfunctioning. “Safety is the No. 1 priority as we apply this new technology at the wind sites,” Kozlowski said. The lights sit atop wind turbines and blink every few seconds to alert pilots flying in the dark.

Why do wind turbines have red flashing lights?

Turbines use blinking red lights to ward off low-flying aircrafts at night. Experts now believe this light source lures bats into the path of the blades, which spin at speeds of up to 170mph .

Why was Texas sky red?

Can wind turbines work at night?

Wind power is greatest in the spring and fall. Wind turbines work at night when solar panels are dormant.

Are offshore wind farms a good idea?

Offshore wind speeds tend to be faster than on land. ... Offshore wind farms have many of the same advantages as land-based wind farms – they provide renewable energy; they do not consume water; they provide a domestic energy source; they create jobs; and they do not emit environmental pollutants or greenhouse gases.
