The POWER Act
Data Center Policy to Protect Illinois Communities
Protecting Our Water, Energy, and Ratepayers: This new legislation will hold data centers accountable, protecting our wallets and our communities. Without guardrails, data centers could increase our electricity costs by $37 billion through 2050. That’s a 24% increase!
Building Long-Term Resilience
Protecting Our Wetlands
We packed the House Energy & Environment Committee to urge lawmakers to safeguard our waters, wildlife, and communities by supporting the Wetlands Protection Act. Thanks to our visual impact (check out our cute wetlands-themed t-shirts!), the bill moved forward and passed out of committee. Let’s keep this momentum going!
