Giving brainiest how did windmills impact the westward expansion in the u. s. before 1900? a) they provided energy and water to new settlers along the plains and western united states. b) windmills became obsolete as new means of producing energy and water were invented in the 1800s. c) this invention created tension between the native americans and american settlers moving from the east coast. d) windmills created a financial burden on settlers because many were not able to afford the cost of building them.

The correct option is option A.

Before 19th century, the Great Plains were not fit for cultivation and were termed as the “Great American Desert.” Droughts were common and followed by rainy spells. The sun along with wind would dry up surface’s moisture. In these plains, European windmills were also impractical. The new windmills were designed to help the settlers on the plains. These could efficiently pump water from underground at a steady rate and could shift into the prevailing winds and functioned well in fast and slow winds.
