Greta Thunberg

I worked out a few months ago that my company had helped reduce the amount of carbon pumped into the atmosphere by around 6 million tonnes since I set it up.
And that was not including any LED jobs we have done and didn't include any PV projects.

I think with all of that reduction I am allowed to eat a steak or two here and there.

I sleep easy at nights (when Joseph allows).

Those are rookie numbers, my company has reduced the carbon by at least 11 million tonnes...

Anyway, how did you work those figures out, Geoff?
We've fitted about 3,000 x 300Wp panels this year, in Ireland you get about 80% of peak, so that works out to roughly 720,000kWh worth of electricity produced.
How much carbon is there per Kw of electricity from:
A) coal power station
B) gas power station
C) nuclear power station
D) Wind power

Oh, I hate exam questions!

Is the answer twelve?

I was going to ask how many you'd done with the PV you install.

The figures I've used are based on the Burner Management Units we've installed, the 6m is based on the a 16% saving in gas consumption, so the real figure is much higher as the savings they make are often in the 20%+ range. But I'm happy to be doing my bit.
 
Interestingly the eh-Golf has an economy gauge on it in miles per kiloWatthour. I was getting around 3.9miles to the kWh. It got me thinking, what's the equivalent in miles per gallon.

If I get 50mpg out of my Seat Leon, does that produce more CO2 than the EeeeeGolf doing 3.9m/kWh via the coal burning power stations producing the elctricity?
Ignore building the lithium batteries for the moment.

So how many kWh saved and what carbon intensity are you using?

Using government figures (0.185kg/kWh for gas) this means you are saying you have saved 32 million kWh of gas. Or £1m worth by my reckoning. Over what period?

So 315g per kWh and I I was getting 3.9 miles per kWh in the eGolf means that for every mile I was using 80g of CO2 equivalent which is roughly the same as a VW Up! Not bad...

Or, in reality, a bit ****. Not exactly zero emissions eh? I imagine in summer it is quite a lot less, as we are currently at 22% renewables, but peak at over 50%.

Over about 7.5 years at the time.

The figures I used were 'rough' as it's not physically possible to calculate everything without spending a fortune on monitoring.
It's somewhere in the right ball park though.

And yes we use the 0.185g/kWh in our carbon saving sums.
