Celebrating Sun Day in Davis

Sun Day, September 21, 2025

An invitation from Yolo Interfaith Alliance for Climate Justice

What is Sun Day?

Sun Day is a day of action on September 21, 2025, celebrating the power of clean energy.  The purpose of Sun Day is to remind everyone that solar, wind, and batteries are now the cheapest form of power on the planet, lowering costs, creating new jobs, strengthening our communities, and helping fight climate change. On Sun Day, hundreds of actions across the country will underline that we want and need to keep spreading this green, affordable technology, locally and globally.  To learn more, visit:  https://www.sunday.earth/ 

How is Yolo County going to celebrate Sun Day?

The Yolo Interfaith Alliance for Climate Justice invites you to join a Sun Day rally at the corner of Fifth and B Streets (in front of the Davis City offices) in central Davis, from 2:00 to 3:00 p.m. on 9/21/25.  Free parking is available in the lot behind the city offices. Bring a sign championing solar energy (see below), sunhat, sunglasses, and a water bottle.  We will spread out from the corner with our signs to share our messages about sun and wind power.

How do we prepare for the Sun Day rally?

  • Put an announcement of the Sun Day rally in your church bulletin (and other media as well – all are invited) as soon as possible and for every week before the rally. An example is provided on the next page of this information sheet.  
  • Include in your announcement when and where people can make signs for the rally between now and Sept 21.
  • Signs of all sizes are needed, including some big signs with bold artwork and large lettering that can be read easily by those riding by.  Find inspiration and fun in the Gallery of suns on the Sun Day webpage: https://www.sunday.earth/gallery.  Read on for additional details on sign-making for Sun Day.  

Making Sun Day signs 

    • Lynne Nittler will drop off some sign-making materials at your place of worship during the first week in September. You will need to provide markers, crayons, paints, scissors, stapler or glue, etc. Take photos at your sign-making sessions.
    • Signs can be of various types:
      • You can follow the directions on the “Draw a Sun” portion – https://www.sunday.earth/welcome – of the website, doing your drawing on the computer and then printing it. It will be rather small for a rally sign, but you (and your friends!) can make several and mount them together on a single piece of cardboard for a larger sign. If you choose this option, you will be using a template that guides you to draw just half a sun, rather than a whole one. This honors the idea that we are halfway to a world run on solar power, because we have the technological know-how but not yet the needed political will—thus the need to rally!
  • You can use a paper plate to make a sun and decorate both sides as you wish or write short solar energy slogans on it. Some examples: I love clean solar energy!     Wind energy is a breeze!     Go solar!     Solar energy is clean!     Install solar hot water!     Solar is free power from the Sun!     Support wind energy!     Install rooftop solar!   Solar power = people’s power.  We want solar power! Or write your own message.
  • You can make larger signs or banners that can be read from farther away. Use large, bold lettering and high contrast colors.
