Release Notes

As part of the main Communergy project, this system tray application has been developed to display the current carbon intensity (the amount of CO2 emitted per kWh of electricity generated) of the UK National Grid, relying on data from http://www.realtimecarbon.org/.

Running the installer adds the Monitor application to the Startup directory, adding a traffic light icon by the PC clock.

Monitor the current carbon intensity of the grid using the traffic light icon - hold back on heavy electrical use when it shows red, as this means that a larger number of fossil fuel power stations are being used. Green means a lower than normal amount of carbon emissions, as wind and nuclear take over. Click on the icon to open the Real Time Carbon homepage.

You can change the limits to decide the light colour in the config file, the completely arbitrary default values are:
Green - less than 0.5 kg p/kWh
Amber 0.5 to 0.7 kg p/kWh
Red - over 0.7 kg p/kWh

Full details of the methodology used to calculate this figure is presented here: http://www.realtimecarbon.org/resources/RealtimeCarbonMethodology.pdf

Ecotricity, the UK Green Energy supplier, provide a similar page here: http://www.ecotricity.co.uk/about/live-grid-carbon-intensity. Change the "infoUrl" setting in the config file to this url to open that page instead, if you wish.

The raw source data, detailing current grid production and the fuel mix is available here:

This is the first release, as a spin-off application from the main project. All comments warmly welcomed.
