2. There are plans to build wind turbines in Tornado Alley

Running through Texas, Oklahoma, Kansas and Nebraska, Tornado Alley is one of the most devastating areas of tornadoes in the world. Its danger could be harnessed by humans though as plans have recently have been made to place wind turbines in the worst affected areas. Read more about this possible renewable energy source here

3. They may be powerful but they are no match for their solar equivalents

Our twisters on Earth are pretty impressive but are no match for the 70,000km (43,496mi) tall beasts on The Sun. Check out some ace facts on them here

4. The worst tornado in history was in 1925

5. Or was it the most deadliest?

A 1989 tornado in Bangladesh was quite possibly more destructive than the Tri-State with 1,300 dying as a cause of the twister. A reported 80,000 people were left homeless with the slums the most affected areas. Bangladesh is one of the worst affected areas by tornadoes on Earth along with the USA and Canada.
