Thoughts for Copenhagen

Around fifty years ago energy was relatively expensive and formed a large part of most people’s budgets. Then in the United Kingdom there were few homes with central heating and most homes had one light bulb for each room. Water was generally heated by an electric immersion heater (usually made of copper and un-insulated) and people bathed less frequently than they do now. Most heating was by coal, which was cheap. I remember my parents having to fret over the electricity bill far more than they fretted over the coal bill. Continue reading

Vote for a steady state economy

Economic growth is assumed to be a Good Thing, by most economists but it is responsible for most of the environmental problems that affect us, because the growth is uncontrolled and rewards greed. Economic growth is presented as a benefit to society but it is actually a cancer infecting the environment which will ultimately destroy society if we are not careful. It is necessary to find a sensible alternative to economic growth and one of the ideas out there has originated in the United States by Professor Brian Czech. He calls it the Steady State Economy and founded CASSE in order to promulgate its concepts. Continue reading

Rain, rain go away

One of the fears of climate scientists was that as the planet got hotter so weather patterns would change radically and that one of the changes would be that some parts of the world would have droughts and others would experience heavier than normal rainfall. This fear has proved well grounded. Unfortunately many people only believe what they can see and experience; Hurricane Katrina made many Americans aware of the weather changes and the effects of climate change on weather. Droughts in the Horn of Africa were more severe, longer lasting and killed more people than Katrina but they were far away from the developed world and perhaps out of sight is out of mind.

How to integrate Genersys solar panels in your roof

There are a number of ways of fitting Genersys panels to your roof but the best and most aesthetically pleasing to have a roof integrated installation, which we call “an in roof system”. Fitting the panels “in roof” prevents unnecessary heat loss, especially in winter when the wind may blow around panels that are installed parallel to the roof, take heat away from them. In roof installations look neater and are usually worth the extra money.

If you are interested in seeing how the panels are connected to the roof to become roof integrated you can click on the links below and watch the Genersys video showing how this is done.

 

 

 

 

The Energy Bill

The United Kingdom Government has published its programme of legislation for this the last Parliament before A General Election. Many doubt whether any of the proposals will be enacted in law before Parliament is dissolved. Many of the proposals are simply window dressing but among the more useful pieces of legislation, if passed, will be some aspects of the proposed Energy Bill. Continue reading

Our meaningless emission reduction targets

I have been trying to understand the basis of measuring the United Kingdom’s carbon dioxide emissions. The country’s much publicised and apparently legally binding emission reduction targets depend upon these being accurately measured. If they are not accurately and consistently measured then they are not real targets at all, just froth and bluster. What, then, is the truth? Continue reading

DECC misses the point on climate change

Mechanical Engineers are probably the most important engineers; civil engineers construct great and important building works, electrical engineers create things that work with electricity and in electronics but mechanical engineers concern themselves with the design and manufacturing of things, drawing upon the laws of physics and mechanics. They number in their ranks Archimedes, Ma Jun, Al-Jazari and George Stephenson, who founded the Institute of Mechanical Engineering. Continue reading
