    Heya mates,

    I'm looking to improve the way in which I save energy.
    So far I've done the whole insulation, windows upgrading, and I have a small wind turbine installed. Well, it's still not enough and I've seen there are plenty of energy saving devices out there? Any advice on where to buy the best priced ones and what models/types I should go for?

    I'm interested in something for the overall house as well as for specific items, e.g. computer energy saving.
    Some ideas would be most welcome, guys.

    Cheers,

    Tristan

    Hi Tristan,

    I was having a look at this a couple of days ago:

    http://www.directenergy.com.au/

    I dont know how much these units are but theyre worth a look.

    Most of the energy saving devices simply tell you how much it is costing to run an appliance and help education wise. I would be a little dubious about anything that reduces the amount of power an appliance uses as dropping your voltage (like what happens in a brown out) can damage appliances.

    My advice, if you want to reduce your consumption turn things off and don't use items if you don't need to. Get an energy auditor out to your home to advise on how to make your home more energy efficient (and not the type that hand out shower heads and light bulbs )

    Tristan,

    This is the one I'm using: http://www.energysaver.net.au/product_info.php?products_id=40&osCsid=3a5525faba4862a7c9be663055267709 , it's really neat and it really helps you understand how much and especially where your electricity goes - basically, it's an green energy auditor in your hand

    You might want to check other products on that website too - but, again, the best thing you can do is not to use "brown out" devices, or any devices that minimize your energy output, but rather gadgets that give you insight, information, and, best of all, control over the way you use energy.

    In light of the recent carbon tax i distictly remember our PM saying that when prices rise people find a way to cut down and reduce their costs. What this ment to me was that she was saying that its "OUR" problem, "the people" and that imposing a tax solved the governments obligations and problems.

    My personal opinion is that instead of using less of the monopoly controled power, individuals should be producing as much as they can, and not supply it back to the grid, thus allowing the power companies to sell your power at a profit (run a lead to your neighbours if you have excess)

    If you can produce all the power you need, no need to cut back on your usage

    Cutting down on your power use and making an effeciant home is admirable, and for many of us the best we can do depending on our situations, but if you are in a situation where you can produce more of your own power, it would be my choice over cutting back usage.

    If you look on some DIY websites (www.thebackshed.com is one of the best) there are some amazing solar and wind turbines being produced by many regular peaple who have just decided that making your own power makes more sense than anything. A lot of this can be done at a fraction of the cost of what some of these solar/wind turbines installation companies offer.

    If you search for wind turbines on in this forum you will see my self made Lenz2 turbine. Total build cost under $100 so far. I am progressing through the electrical side of things at the moment (reconfiguring the coil and building a voltage regulator) according to thebackshed where a lot of peaple are using these alternators they are generally good for up to 400watts peak output (14V @ 30amps) about the same output as 6 average size solar panels that I estimate would cost me at least $100 each to make.

    At the end of the day I guess it depends on what you can afford. If money is no issue, the most conventional way to get off the electricity grid would be to go a solar/wind combo. It's just a mater of figuring out your consumption in Ah (amp hours), then figuring out the number of batteries you will require to maintain that consumption relative to the charge sources. Solar is very reliable but peak power demand is usaully early evening for a lot of house holds so a big bank of batteries is needed to get through the night, wind turbines can help the evening power drain but wind is less reliable in most areas.

    The most expensive items regardless of your set up are always going to be the batteries and inverter.

    sorry for ranting on, but I personally feel we are being forced/pushed into this conserve energy crisis, if our power source was clean, then how much we consume shouldn't be an issue.

    We can adjust our night time use to ease the battery load. ZZZZZZZZZZZZZZZZZ.

    I think what most people of aus need to understand is that most have no idea the real cost of producing energy by burning fossil fuels. Now they are getting a chance, to find out the real cost, of course the complaints will come from the people who out of touch.

    Nature is our most powerful force, learning to play and work with it makes sense to me.

    earth care, people care and fair share.

    I like how the "green" approach is to steer away from combustion type power generation, we have that much bushland around our cities that is getting more and more fuel on it's floors, just waiting for the next bush fire, why can't we utilise this this potential energy harvest it and burn it to generate power, aside from some of the stuff comming off it which could be captured anyway, it would also help to reduce the amount of bad bushfire we have

    Harvesting dead wood from National parks has been possible in the past by applying for a dead wood permit, from memory it was about $15/20. Some say the old logs and a decaying wood is a part of the biocycle and is habitat for a great many creatures, I agree but when a fire rages through not to many of them survive such ferocity. Some plants need to be burnt to set their seeds, so some high risk areas would need to be control burned regularly, housing and buildings would be underground and able to withstand burn offs and warning systems in place.

    As a greenie working and living in the real world, I see no problem with burning timber as it is renewable by planting more, its the fuels that have taken millions of years to exist and will be gone in a few hundred years, we are not good at making coal or oil, so being more effiecent with how it is used would worth the effort.

    The sun is the most reliable source for our energy needs for as long as it shines, geothermal sounds good but are the intense pressures underground going to cause geotectonic disruption to artistion waters?, sure there are a few more concerns to nut out.

    Cities built in very stable geological locations could be best served with large geothermal generators, and more remote rural areas haveing stand alone systems for each building.

    High temp solar hot water systems running steam turbines would provide daylight power and heating. Timber feed boilers by night. All fed with water preheated through compost piles that heat to very high and stable temps, night and day. Some devoplement into splitting hot water into separate gases and bring them back together when the heat is required at night, sounds weird but some serious research and testing has come up with good results?.

    Awesome advices, guys, thanks a lot.
    @ David: I got that device from energysaver.net.au, so far performs well, and it's giving me a good idea of what I'm spending and where. In case anybody is interested, there's a discount coupon code: ES351408, take it and share it

    Thanks for recommending the website, I got some more products from there: http://www.energysaver.net.au/product_info.php?products_id=42&osCsid=3f8c4785769ab3e0be8361c0d2ad688b , it's a so-called ECO Button, basically a standby quick button, but it's useful when "nature calls" hehe.
    Also, kids are having a blast with the weather station: http://www.energysaver.net.au/product_info.php?cPath=8&products_id=23. Yeah, I have geek kids, I know They take after their dad, haha.
