We’ve had our first full month in the Eco-House, so here’s our monthly report – our Carbon Footprint for August. We’ll be plotting these each month on a graph to see how we go. I’m anticipating that this’ll be one of our lowest months – the lights have hardly been on, and there’s been no heating used. It’ll be interestiung to see how we go through the winter, and then how next year’s figures compare.

Our Energy Consumption: 1396 kWh

As you can see, the majority of our energy came from using the car – 830 miles at an average 49.9 MPG . That’s significantly higer than previous months – not helped by a 300-mile round trip on the bank holiday weekend. Now lets convert this into our Carbon Emissions:

Our Carbon Footprint: 412kg of CO2

What’s interesting to see here is how the electricity we use has a much higher impact on our Carbon Footprint than it should for the energy we use. With that in mind we’ve changed electricity supplier to Good Energy. Good Energy only supply electricity from renewable sources, so we can remove electricity from our carbon footprint.

Our carbon footprint with 100% renewable electricity: 258 kg

So that’s a significant reduction – 37% off our carbon footprint in one go. If every month was the same as August we’d be on track for an annual carbon footprint of just over three tonnes. Not bad for the four of us. Unfortunately not every month will be like August – so we’ll see how we go!

Our initial target is to come in well under the nine tonnes of CO2 per adult that is the average Mark Lynas quotes in the Guardian. To make the comparison fair though we need to include a couple of other things on the graphs – water consumption and public transport use. I’ll try and get some of those on the September figures.
