A few years ago I started writing regularly about electric cars and the batteries that power them-technologies that are helping humanity transition away from reliance on fossil fuels. And as bad news continued to pile up about the harms caused by climate change, I started to think harder about my own carbon footprint.

So last year, my wife and I got solar panels for our roof. Then we replaced our air conditioner, getting a model with a heat pump capability. Shortly after that, our boiler sprang a leak and we got a new high-efficiency boiler. Then we purchased a battery electric car.

We haven't yet achieved a carbon-free lifestyle. The new boiler burns natural gas, and we're keeping our old gasoline-powered car. We also have an oven and fireplace that run on natural gas.
