Why should anyone buy a solar system?
For most people this is the critical question that the solar thermal industry needs to answer. We have the product, we have the technology, but why should anyone part with their hard earned cash – for a solar heating or a solar water heating system?A good solar system costs [...]

There are some positively misleading reports about what solar water heating does and what it saves. In the Telegraph on Saturday one “expert” who turns out to be a builder claiming to “give it to you straight, Jeff Howell, claims that the annual savings are less than £70 per year and that at this time [...]

Professor Seamus Garvey is a Professor at Nottingham University’s School of Engineering and he has been championing the concept of electricity storage by using compressed air. Storing electricity is hard to do in an environmentally acceptable way.
Electricity demand and supply is intermittent. Electricity generated from renewable sources is also intermittent. We can store electricity [...]

Iain Fraser posted a response to my post of 10th March asking me to cite my sources for my figures. It is a perfectly reasonable request but as I was away from my office it was hard for me to do that. Mr Fraser may think that I have a bee in my bonnet about biomass [...]

Are we creating fewer carbon emissions? This can be very hard to discover. If you want to look at the world as a whole you have to measure the amount of carbon dioxide in the atmosphere scientifically. The last most accurate measurement was 381 parts of carbon dioxide per million parts of the atmosphere. Various [...]
