Electrifying Our Old Oak Park Home more »

In 2022 and 2023, I documented our process of fully electrifying our 100-year-old home in Oak Park, IL. We installed solar panels on our roof (giving us a source of free renewable electricity), switched out our gas furnace with electric heat pumps, and replaced all gas appliances with electric equivalents.

Electrifying Our Old Oak Park Home #4: One Year In

Published on Jun 29, 2024
A little over a year ago in April of 2023, we completed the electrification of our house. Since then, I’ve received a lot of interest in this project, was awarded a Green Award by the Village of Oak Park, and was even featured in the Chicago Tribune! While the blog posts I’ve written have been useful to reference and point people to, there’s one outstanding question still to address: How much money are these electrification changes saving us, and how long until the upgrades pay for themselves?

Introducing Decarb My State

As part of our 500th Chi Hack Night on July 12, 2022, I gave a lightning talk debuting DecarbMyState.com, a new website that shows where emissions come from in each state to galvanize action on climate change through clean electrification.

Intro to being anti-racist in civic tech

What does it mean to be anti-racist? What is white supremacy culture and how does it show up? Over the past months, Chi Hack Night’s Diversity, Equity and Inclusion (DEI) committee has discussed and researched these questions. I am joined by fellow Chi Hack Night Board Members Ryan Spencer and Samantha Evans to share what we learned in our blog post so that we can all work to make our communities more equitable and just.

Illinois Solar Map
https://ilsolarmap.com

As of May 2023, 1,622,000 kilowatts of operating solar capacity have been installed in the State of Illinois thanks to the Climate and Equitable Jobs Act (CEJA). The Illinois Solar Map allows you to explore solar projects by Census Tract, Place, County, and State Congressional Districts, as well as by category of project.

Decarb My State
https://decarbmystate.com

With volunteers at Chi Hack Night, we pulled together emissions and electrification data for all 50 states + DC and organize it based on the biggest sources of climate pollution: the machines we use to heat our homes, cook our food, get us places, and produce our power. We count and name every coal, gas and oil plant that needs to close, track how many of our buildings and cars have been electrified, and how much wind and solar has been built.
