Marathon County is working hard to save energy. In 2025, more than 100 local businesses,
manufacturers, schools, hospitals, and farms improved the efficiency of their facilities with support
from Focus on Energy.

Farming has played a major role in this achievement. Last year, 62 farms in Marathon County
completed more than 180 energy-saving projects, resulting in $325,000 in total savings. These
upgrades help family farms lower costs and stay strong for the future.

No Joke Dairy is a fifth-generation family farm in Marathon County that has belonged to the Redetzke family since 1911. Otto and Ottelia Redetzke built the original barn, and the farm has remained in the family for over a hundred years. Although the family stopped milking cows in 2011, brothers Matt and Sam Redetzke chose to start the dairy again in 2015. They restored the herd and brought the farm back to life. Now, four generations work side by side, making it a family-run farm.

The farm cares for 400 cattle in total, including young animals, and has a milking herd of around 200 Jersey cows. The Redetzke family also grows crops on 660 acres to feed their animals, keeping the farm self-sufficient.
