As a utility communicator or energy efficiency manager, you’re asked to help members lower their bills — and to prove it. Powerful Online Calculators give you a polished, accessible, always-current toolkit that lives on your site and does the explaining for you.
Energy Saving Tools, Done Right
Plenty of vendors will hand you a generic widget and walk away. The result is usually a clunky embed that doesn’t match your brand, isn’t accessible, and leaves members guessing at what the numbers actually mean.
We take a different approach. Every calculator is designed to feel like a native part of your website, written in plain language, built to WCAG accessibility standards, and supported by the same team that maintains the rest of your site.
You get tools your members trust – and that your efficiency programs can point to with confidence.
What’s included with every calculator
- Matched to your utility’s brand, colors, and fonts
- Mobile-first and fully responsive
- WCAG & ADA accessibility built in
- Plain-language results members understand
- Hosted, maintained, and updated by Powerful
- Editable rate and cost assumptions you control
