If you want to get PC software to go with it, take a look at Weather Display, it's what I use here.

Another good weather forum is

26 x Trina Honey 250w panels. (wish I could work out how to upload to

I'd suggest Cumulus software: - excellent response from the author and other knowledgeable users/developers on the forum if you have problems or suggestions for new features too.

My Cumulus weather page is here: Loomberah weather and astronomy including live solar radiation intensity and UV + Gunagulla aquaponics, organic eggs and cherries

FORGET that - they are useless ! Another stupid idea from a stupid Government !

The guy has mentioned "beyond normal" attempts to control energy.. The only real method is as others have said - Measure and Switch.

Know which of those devices are "Stand-By-Wasters". Use your hands !.. Let your fingers do the walking !
Feel things - If it's warm and OFF - you are in trouble !
Feel the facia on the dish-washer - MANY run very warm when OFF. Same for Laundry-Washers and dryers

Plug-Pack power supplies that are warm, are wasting power..
I think that Government specifications require "Switch-Mode" supplies, that have no transformer-losses.

NO - Forget Energy Auditors - They just check for the obvious !

Ditch the PC and replace with Laptop
PC = ~300W with the monitor
laptop very rarely more than 50W running.

I scored a second hand lappie, threw in a new Hybrid drive. new battery and power supply.
for $200 I saved it from landfill and will save more than its purchase price in power every year

Its a dell XPS M3300 and I can get it down around 25W for doing things like posting here :geek:
8E + 8W + 8Nth Garage CMS2000-1 with ~4500W in 3 strings of 8.
Fronius Galvo 3.0 inverter with ~6.6kW panels
12x ZNShine + 12x 180W Solarfuns both NW + ZNShine 12x190 facing SE.
Edwards Solar Hot water

Luck Favours the well prepared.

Insulate your fridge. I did so and energy consumption is cut down to the half. See here:

We have nearly eliminated our ghost power consumption. The simple purchasing of foot operated power boards, has turned our home into night, when leaving or going to bed a few simple steps eliminates all unnecessary ghost power consumption. Some things must stay on, like our wifi router so we kept a few origional power boards ( power strips) and pluged our new foot operated boards directly into the old ones......things that stay on are in the first board.....those that go off go into the second...........being carefull not to over load of course. Many appliances like our Multifunction printer were consuming power totally unnecessarily. Due to our age getting down to all those double power points was a real pain, possibly the main danger now is very little light to navigate with. We have made a real effort to stop wasted energy, external insulated roller shutters and very good insulation has nearly eliminated heating and cooling......we live in county S.Australia so heat waves inthe high 40's are normal, as are regular below zero frosts. We have only 8 solar panels and evacuated tube hot water on an all electric home, and despite our states high power costs, our last power bill was only $67.00. :D :D

Do an energy audit YOURSELF.
Monitor every single appliance and its normal usage pattern, this is going to take quite some time, but you will be truly amazed at some of the things you will discover.

The energy hogs are invariably the smaller things that draw constant low power 24 hours per day.
Something that is only used for a few minutes per day, or fairly infrequently, (like power tools) even if it is a very high power appliance, may not add substantially to your total final overall power consumption.

Examples of energy hogs are mains powered wall clocks (with synchronous motors), the old style warm running plug packs, and inefficient lighting. For a wall clock, a single AA battery that lasts a year has to be better than a small 230v motor that uses 12 constant watts.

I was astonished to find my washing machine uses the same amount of power when just switched off and otherwise sitting there unused, as turning it off at the power point and then doing one full heavy duty wash and fast spin dry cycle every single day.

Another villan was my garage door opener, that cannot really be turned right off without considerable inconvenience.

If you do a comprehensive energy audit, you will discover a great many things that can be improved upon quite simply and at low cost without major changes to your way of living or having to adopt the austere discipline of a monk.

Its been a great deal of fun and a very interesting exercise to almost HALVE my power consumption.
And what I had to buy to do that should be recovered in about an estimated four years of power savings.
