Help Celebrate National Sun Day: Sunday, September 21, 2025
Saturday, September 21, 2025, will be a national day of action to celebrate the power of clean energy. The day will be full of events highlighting the capacity of solar panels, wind turbines and batteries to reduce greenhouse gases, lower costs, create new jobs, and strengthen our communities.
Locally, organizers are the Energy Committees of Lyme, Norwich, Thetford, Sustainable Hanover and Sustainable Lebanon. There will be a parade starting at 10:30 am from the Ledyard Bridge to the Norwich green, with a range of solar-focused activities and demos on the Norwich Green from 11 am to 1 pm. Participants on the green will include Revision Energy, Rooted Gardens/The Electric Lawn, the Norwich Bookstore, Fossil Free Dartmouth, area churches, VT and NH clean energy advocates, and more. Please join us for the parade followed by fun and information on the Norwich Green. If you would like to attend another of the thousands of events across the US – or invite your friends and relatives to do so – you can find more events on the Sun Day website: https://sunday.earth
Sun Day will occur on the Fall Equinox, one of two days in the year when northern and southern hemispheres of earth get an equal amount of sun. The Sun Day website reports that “solar power combined with battery storage is now the cheapest form of energy generation in the world. It’s also a huge and fast-growing part of the electricity grid. Nearly five million US homes already have solar panels and last year alone the US installed 50 gigawatts (GW) of solar power, more than 80% of all new electric generating capacity added to the grid. Solar energy – large and small installations currently generates enough electricity to power 28 million homes in the US. Wind energy is growing too: more than 42 million US homes are now powered by 150 GW of installed wind, and wind turbines often work best at night when the sun isn’t shining. Add in innovations like local or large-scale batteries, and you have a recipe for transitioning toward 100% clean energy, around the clock – no carbon pollution required.”
