I visited the ecobuild exhibition in London last week mainly to see what firms were offering products that would clad a non-cavity wall to reduce heat loss. I found some and will be following up with quotations from them. Details will appear on my permanent page about this in a few weeks time.

I looked round the whole exhibition and noted the large number of stands for photovoltaic panels and some for heat pumps. Although the PV technology is still evolving, and I will keep checking what is on offer over the next two years, I was encouraged by the effort now be made on technologies that can reduce our CO2 emissions.

Politically the situation does not reflect this. Here are two excellent articles on global warming politics: The Attack on Climate-Change Science & The Wrong Kind of Green. Fortunately many developers and manufacturers are working to reduce our reliance on fossil fuels.
