Solar Share Energy Offsets

One way you can participate in the Solar Share community is by purchasing energy offsets to lower your carbon footprint generated by day-to-day activities. You can start small, like offsetting your cell phone, or go big for an event, like a wedding.

What are Energy Offsets?

Electricity powers our daily lives - from the coffee you make in the morning, to the air that keeps your home comfortable, to the alarm you set at night. With EPB Solar Share, you can purchase carbon offsets in 100 kWh blocks to counteract your personal energy use. See below for examples on how you can offset the average annual use of common household items. Each offset block of 100 kWh is $5.

To purchase one-time energy offsets for your event, enter the details at this link and submit your information via the form.
