    Does anyone know a site with wind turbine designs which are easy and cheapish to build? My family wants to start saving the planet and all that and rather than spend £3,000 on a wind turbine from B&Q, we would like to build our own

    Why wind turbine?

    There are many other ways to save the planet such as avoid pollution created around us... :-D

    solar panells are poinless and expensive in Sheffield, there is never any sun and we already have energy saving bulbs, now we are trying to cut down on the electicity used from the grid

    The best way is to use solar heating panels [the ones that heat water] Let me offer you some figures...

    The water temp coming into your house will typically be around 17c fo every cc of that you wish to boil you will need (100-17)*4.2 joules of energy (a joule is 1 watt expended for one second) so if you want to boil a litre of water it will take at least 250,000 joules which is a IKwatt kettle for around 4 minutes - now for every 1c you save around 4000 joules of energy. solar panels will [yes even on cloufy days] raise the temperature at least 10 degrees and in sunlight by considerably more.

    Energy saving tips:

    Have a look at the thermostat on your central heating tank - most are set at around 75c which is ridiculous as you then ned to cool the water to use it! I set mine by taking a shower, measuring the temp of the water then adding 5c (so it's set at around 45c) by this reduction alone I have save 50% of my water heating cost, If I added Solar panels then over the year this would drop by another 50%.

    Put only enough water in your kettle for the purpose (but ensure the element is covererd by no less than 5mm of water.

    Turn down the central heating stat (to 19c) and set the timer for it to be active betwen 4PM and 10PM only

    I have a wind turbine (80 watts) this is connected to several old car batteries and provides power for all the battery operated kit we own (all now use rechargeable batteries recharged from the carbatteries using a modified charger) it also powers the lights for the garage and has a 300Watt invertor capable of running the central heating pump and a small freezer for 48hours should a power cut occur. In addition to the turbine there is a 15watt solar cell 'trickle charger' also connected to the car batteries.

    Switch off everything when it's not in use - even your mobile charger will cost you £2-50 per year if left plugged in.

    I have a large four bed house [with a ground floor extension] occupied by 4 people our monthly combined gas& elec bills (averaged over a year) is £43-82 which is about 1/2 the UK average for the average house.

    I'd like to know what else you do towards keeping your bills low maybe I can learn from you...

    cheers megabrain, you've been a great help.

    We want to find ways to BUILD a wind turbine or solar panel though.

    to save energy we have wired our house to as best efficiency as we can and have cavity wall insulation. We have also increased the efficiency of the plumbing (less pipes) so we use less water. We always turn our thermostat down and just put on an extra jumper

    I have heard of an electricity supplier called "Good energy" They are no more expensive than your average electricity supplier, there is however a difference. They spend their profits on research and sourcing their energy from renewable sources.

    www.good-energy.co.uk
    The hand of time rested on the half-hour mark, and all along that old front line of the English there came a whistling and a crying. The men of the first wave climbed up the parapets, in tumult, darkness, and the presence of death, and having done with all pleasant things, advanced across No Man's Land to begin the Battle of the Somme. - Poet John Masefield.
