Sabaidee, Welcome!

This is a community for promoting sustainability in tech and computing. This includes: understanding the impact that our tech/computing choices have on the environment; purchasing or re-using devices that are sustainable and repairable; how to properly recycle or dispose of old devices when it is beyond use; and promoting software and services that allow us to reduce our environmental impact in the long term, both at work and in our personal lives.

This isn't a competition, it's a reminder to stay grounded when making your decisions. Remember: The most sustainable device is the one that you are already using.

Rules:

Stay on-topic. Everything from sustainable smartphones to data centers and the green energy that powers them is fair game.
Be excellent to each other.

I built a quick web tool to compare home heating emissions for different heat sources. (www.cwmenergy.ca)

I put this together to help me understand how fluctuating emissions from the electrical grid and outdoor temperature impact the environmental performance of a heat pump compared to a natural gas furnace.

Would love feedback!

Do you have any thoughts or plans on open-sourcing how the calculations are done? Assuming the values used in the calculations aren't proprietary, it might be cool to do that :) That way no one can argue that the math is wrong.

You don't have to, I think it's rare for a company to do that, but it might fit with the transparency bit. Alternatively, if you list out where the numbers are coming from so that people can confirm the details manually.

Very cool regardless :)

My other suggestion would be to link information about the different types of heat pumps, or a guide on how to get the efficiency value. Similarly, if the heat pump question was at the end, in a toggle format so people can easily swap between the options and compare

I am more than happy to share the calculations - I'm a firm believer in transparency. I'll update along with your other suggestions. Thanks for the input!
