Do you want warmer homes at an affordable price?

Fuel poverty is in the news again with oil prices on the up. The traditional way of dealing with this has been to give people in need a bit of cash to help them over the winter.

Biomass sounds like a great idea, but I've always had a bit of a nagging question at the back of my head about whether it would be possible or sustainable if we all suddenly converted to wood fuelled heating. Haven't we, over the years, been denuding Britain of trees to such an extent tha…

UK renewables lag behind Europe

I’ve got good news and bad about the UK’s efforts at introducing renewable energy. For all the Government talk, you’d think that we’re doing quite well at generating heat and power from renewable sources. But, no, we’re not. In fact, if we compare ourselves with other European countries, o…
