At last THE SUM

Sunday, February 27th, 2005

Given that the car does 5,000 miles a year on average and the scooter mileage is around 500, we can finally calculate our current total emissions (hold breath)…
And the answer is: 21.8 tonnes of CO2 a year. This comes 89% from home energy and 11% from transport.
And we have to consider that:

this doesn’t allow for […]

First Real Changes

Sunday, February 27th, 2005

Signed up with Good Energy. Their system is very clear, although the comparisons with the present are more complicated. Their rate is going to be 8.73p for kWh for daytime usage. The compares with our current Powergen rates of 7.96, but with the first 200 units at 10.18. However this is based on a day/night […]

Oil and Electricity

Wednesday, February 23rd, 2005

First real numbers look horrifying:

yearly use of heating oil (hot water, heating and pool) was 6245 litres
yearly use of electricity (lights and gadgets) was 20,700 kWhs

This computes to CO2 emisions of:

oil = 19,476 kgs of CO2 per year
electricity = 9,192 kgs of CO2 per year

Giving a total of 28,668 kgs per year, or more than […]

A few more key metrics

heating oil - multiply gallons of oil by 11.81 to get kgs of CO2
petrol - multiply gallons by […]
