Delaware Chapter

About The Delaware Chapter

The Sierra Club dates back to 1892 and is the oldest and largest environmental advocacy organization in North America. Our mission is to explore, enjoy, and protect the planet. Since 1992, the Delaware Chapter has blazed trails to protect the environment and to provide opportunities to enjoy and explore the natural beauty of our state. 

As a volunteer-run grassroots organization, we are working to protect our air and water quality and supporting state legislation and policies to reduce the negative impacts from climate change on those precious resources now and in the future. 

Take Action To Stop The Rate Hikes, Before Its Too Late!

Legislators are backing away from their promise to protect us from rate hikes by Delmarva Power and Data Center Developers. Two bills are before the General Assembly right now and facing bi-partisan push back due to a massive lobbying effort by these large corporations.

We need you to remind legislators who they work for and tell them to pass House Bill 233 and Senate Bill 326 to make sure data centers pay their fair share and cap ramped utility spending on our dime.

Check out our fact sheets on these two bills below.

Global Wind Day Events

Global Wind Day Picnic

Saturday, June 13th @ 1PM

Location: Cape Henlopen State Park

Due to emergencies beyond our control, we have to postpone the picnic. A new date will be announced and all tickets will be honored or refunded for the rescheduled date. Thank you for your understanding.

Global Wind Day Kite Flying

Saturday, June 13th @ 1PM

Location: 4361 Weldin Rd, Wilmington, DE 19803 (Field in front of Can Do Park)

Join us as we celebrate Global Wind Day in Wilmington! Like last year, we will be building and flying kites, but we will also have little wind turbine kits the kids can build. You can bring your own kite if you'd like, but we will also have kits so you can design and build your own (available for both adults and kids). 

We will include some limited-edition Offshore Wind T-shirts in the cost of admission for the first 10 registrants!

We will be meeting in the field by the parking lot for the Can Do Playground. You must pay for park entry ($5 for Delaware Residents/ $10 for Out of State).

2026 Energy Video Series

Energy bills are up again, but why? As we did last year, we put out a series of short videos that break down why energy prices are going up, and why they are likely to continue going up in the future unless we drastically correct course and bring more clean power online in Delaware. 

We also go over some more misinformation being put out by fossil fuel front groups and misinformed legislators. We also share some information on how Data Centers will raise rates for Delaware Electric Co-op and DEMEC (municipal energy utility) customers, even when data centers are in New Castle County. Check it out below!

Lobby Day Recap

Delaware Sierra Club members assembled for Lobby Day 2026.
 
THANK YOU to everyone who came out to our "Protect Us All, From Big to Small" Lobby Day this month! With over 30 attendees and 18 lobbying meetings, we truly made our mark on Legislative Hall, and that is something to be proud of. Whether this was your first Lobby Day with us, or you are a seasoned veteran, we had a great time connecting with you all and learning about why you care about wetlands and data centers. 
 
Stay tuned for upcoming ways to get involved via our email newsletters, or join us for our June General Advocacy Meeting on June 8th on Zoom: SC.org/JuneAdv

Please Consider Receiving Delaware Chapter Email Updates!

Right now, about 50% of our members are not receiving our emails! That is usually because when you unsubscribe from a national Sierra Club (or partner) email, they automatically unsubscribe you from our Chapter emails as well. I know, it's frustrating, to say the least. However, you can easily fix it so you can receive JUST our emails. 

Log into your My Sierra Account here.

Check out this quick video that shows you how to "opt-in" to Chapter emails.
