World’s Largest Brat Fest
May 24–26, 2019


Brat Fest is partnering with MGE to advance clean energy as part of Brat Fest’s Green Power Initiative. Brat Fest’s carbon emissions from electricity used to power the Fest will be offset with green power sponsored by MGE.

This partnership builds upon Brat Fest’s Zero Waste Initiative. Last year, Brat Fest reduced overall waste and converted 55% of all waste through recycling and composting. Now, Brat Fest is going green with wind and solar power.

Renewable energy is one strategy for reducing emissions. Energy efficiency is another. Another key strategy for reducing carbon emissions is the electrification of transportation. There will be several electric vehicles at Brat Fest for attendees to check out and learn more about the benefits of going electric.

MGE will have a booth at Brat Fest where you can:
1. Learn about clean energy projects and programs from MGE, such as Shared Solar and Green Power Tomorrow.
2. Learn about electric vehicles – several models of electric vehicles will be on display.
3. Learn how everyone can be more energy efficient.

With the previously introduced Zero Waste Initiative, partnering with MGE to power Brat Fest with green power is a great next step for an environmentally sustainable celebration.

In addition, Brat Fest is proud to roll out Green Cab as its sponsored cab company for the festival. Green Cab will be serving festival-goers throughout the weekend as well as helping deliver brats to Seniors on Sunday, May 26.

11/9 City Passes Change: To Allow Fare Exterior Markings Optional

Amending Section 11.06(10)(a)2. of the Madison General Ordinances to remove the requirement for public passenger vehicles to mark current rates of fare on the exterior of the vehicle if a fare is provided to the passenger prior to departure.

Effective November 9th, taxicabs will no longer be required to place the rates on the exterior of their vehicles, so long as they provide fares to the consumer upfront.

Green Cab lead the charge to eliminate the markings that “cluttered, outdated and added additional expenses to the cars”, – Dani Schmidt, of Green Cab. When we updated our logo, app and website designs earlier this fall the rates for us were an unnecessary part of the schematic. Green Cab operates with the Know Your Fare Before You Ride model. Our riders, whether through our app, website, dispatch or flags, view and receive their fares upfront. Our rates are calculated using a zone based model. Those zones are posted online and are on file with the city of Madison. In addition, we do not surge nor do we charge for time not in motion. Riders fares remain the same no matter the route, nor time it takes to get there.

In car, our driver app displays the ride, including the fare, which can be viewed by the rider as well. For flags and airport pick ups, the driver app will calculate the fare based on current GPS location, and riders destination. Our flat rates are transparent for riders, taking the fear out of not knowing how much the ride will be or trying to calculate the rates from the side door of a vehicle.
