Have you heard about standby power use?

This is when you turn your game console off from the remote control and think it does not consume any power from the grid ... this is wrong ... check this list below that shows the amount of standby power usage of some appliances:

Appliance: (Range from Min to Max); (Average consumption of all sampled units)

DVD player: 0W to 10.5W; 1.5W Subwoofer: 6W to 21W; 11W Game console: 0W to 2W; 1W Audio minisystem: 0.5W to 24W; 8W LCD computer display: 0W to 4W; 1W Notebook: 1W to 26W; 4.5W Scanner / Printer Inkjet: 0W to 10W; 5 W Set-top box Satellite: 7W to 33W; 16W Power tool cordless: 0W to 4.5W; 2W Microwave oven: 2W to 18W; 3W

Remember that these figures are true when the unit is off, but plugged into the grid i.e. you don't use your microwave oven or you pressed the off button on the TV remote control. If you work on the PC it could draw hundreds of watts from the grid. (Whole table here:...

Do you unplug your computer during severe storms? If not, you may want to start.

It’s long been known that frequent electrical storms and power outages can damage electronic devices or full-out destroy them, and that includes computers. Anyone who claims otherwise is lying or misguided. The worst part is that power outages Top 10 Activities To Do When There's A Power Outage aren’t the only concern.

What are the risks of electrical failure? How do they impact your computer? And what can you do to protect your computer from being fried?

The Different Types of Electrical Anomalies

The electricity flowing through your home is not constant. Ideally it would be, but the reality is that electrical currents can ebb and flow, sometimes dropping in voltage and other times surging with extra power. All of these can have undesirable effects.

When power completely shuts off, it’s known as a...

Last week, Tesla launched their Powerwall 2.0 residential battery storage system, a little less than a year after Powerwall 1.0.

Compared to Powerwall 1.0, peak power has increased by 40 per cent, continuous power by 50 per cent, storage capacity by 100 per cent (to 14 kWh) and an inverter is included. And all this for US$5,500 ($A8,800) – about the same price as Powerwall 1.0.

In other words, the price per kWh stored and re-used has halved in less than a year. Indicative installed prices in Australia are a little over $10,000. The commonly accepted wisdom was that battery costs would decline more gradually than the precipitate decline seen in solar PV costs. This has been proved wrong.

Let’s do a solar PV+battery+grid versus grid-only price comparison.

First, let’s assume a 4,800kWh per year household in Adelaide and that its electricity bill is either the average of all 77 market offers after all conditional discounts, or the average of all 77 Market...
