Personal story:

I first started in renewable energy about 30 years ago when my children were very young. We had frequent power cuts, so I rigged up a car battery, charged by a home made bicycle wheel wind turbine. This only gave enough power for a couple of lights in the house, but we could still manage in the dark with no electricity. Later I increased the size of the battery and incorporated a solar panel to harness more power. When renewables became more mainstream, I found I had the knowledge to help myself and others to be more green. My background is in engineering and now being semi retired, I have done many jobs on the house to improve our energy efficiency. I have created a website, to describe what has been done.


I have always been keen on energy saving renewables and have experimented with things such as bicycle turbines and different ways of charging batteries (solar, bicycle generator etc.). Previous experience has made me aware of what are appropriate technologies in different types of houses.

I am more concerned about the environment and energy security as I’m getting older – especially aware of rising energy prices. My aim is to be as energy independent as I can and to save as much energy as possible. Also I quite like the challenge of it and the high tech solutions which I’m able to understand…the more bells and whistles they have the more enthralled I am by them.

Property background:

The property is a detached 4 bed house built in 1975, in a semi-rural area.

Key changes made:

The main changes to the house apart from insulating walls and the loft and installing double glazing in windows and doors, were renewable energy sources. We have PV, solar thermally heated water, a wind turbine charged battery system and a wood stove. Other eco measures include rainwater recycling and low energy use lights and appliances.

Measures installed in detail:

  • Cavity wall insulation on all external walls
  • Condensing gas boiler is a Glow Worm Flexicom 24HX
  • PVCU double glazed windows and doors
  • Loft insulation 270mm
  • Low energy appliances: A rated Bosch fridge, freezer and dishwasher
  • Low energy lighting: LED lighting in kitchen, compact fluorescent lights in rest of house
  • 4kWp Sharp Solar PV panels with Sunny Boy 3800 inverter. 250w battery backed system with Studer inverter
  • 30 Kingspan HP200 Solar thermal tubes and new 197 litre cylinder
  • Rainwater recycling with 1000 litre tank for garden watering and flushing two WC’s
  • 120W wind turbine charging 10kWh 12v battery system
  • Wood stove
Benefits of work carried out:

Being an engineer, I’m able to understand how things work so putting these things into practise myself wasn’t too difficult and it became sort of an obsession after a while. Energy consumption has definitely reduced and we are generating as much energy from PV as we use, which was what we had expected. The whole process has also made us much more aware of where energy comes from and the value of energy. We are very happy with what we’ve done and are definitely encouraged to do more in the future.
