What is a Flex Alert?

Question

What does Flex mean?

Answer 1

Now we do not have much context. Flex fuel vehicles are vehicles that can run on gasoline or any blend of ethanol up to 85%.

Would a flex alert be a warning that you are trying to use more than 85%, or more than current conditions allow for?

Answer 2

Flex means be flexible with your energy use.  You should be thinking "Do I really need to run the washer and dryer in the middle of the day?  I could wait until night." or "Do I really need all the lightbulbs on?  I could just open a window."  Being flexible with your energy by doing these simple things help take strain off the power grid during the middle of the day.

Answer 3

it means to save energy. if too many people are wasting or using energy it will cause a black out.  so if you see a flex alert  turn unnecessary things off this will help the main power source to not overload.

Answer 4
