The European energy lobbying group 2000WATTS.org proposes that 2,000 watts is the amount of power that would be available to humans if each one of the 7.9 billion people on the planet had access to the same amount. Their concern is that our power resources are dwindling.
Whether you agree or disagree with their assumptions, it is interesting to consider how much power our frequently used appliances require. When I lived in a city, I never thought about this. I just flipped switches and paid utility bills. However, with so many parts of the country suffering power outages, I imagine that more people are now wondering, “If the power goes out, what do I do?” What could I run with a generator of this or that size? How much fuel would that require?”
Here in remote Alaska, we built our own power supply so we are alert to power hogs and power sippers that we decided to buy or do without. And since the generator we use as a backup to our solar panels and wind turbine is a Honda 2000 (producing 2,000 watts), we know how much our various appliances and tools require and which ones we can or cannot use simultaneously without tripping a circuit breaker.
A fabulous resource for prudent people adding up their power usage in order to determine an appropriately sized backup generator is Generatorist. It identifies the power draw of appliances ranging from full house A/C units to a night light, as well as commercial equipment and RV gizmos. It also lists products you can buy to measure the current draw of each appliance in your home. We have one, called a Kill A Watt.
Additionally, homeowners will find that many, but not all, machines list their amp, volt, and watt requirements in a plaque on the back or bottom.
FOR OUR HOUSEHOLD
The power hogs in any home are appliances that create heat and move water.
Therefore, at our off-grid home, we do not have any of the following electric appliances:
- Oven: 2,150 watts
- Stove: 2,100 watts
- Dishwasher: 1,500 watts
- Clothes dryer: 5,400 watts !!!
- Hair dryer: 1,250 watts
- Home heater: (highly variable, with furnace and fans or radiators, other)
- Air Conditoner: (highly variable, by BTU size, and window or central).
See Generatorist for more examples.
Instead, I hand wash dishes, line dry laundry (I love that fresh scent), cook on a propane stove/oven with a manual pilot light ignition, heat the main cabin with wood and warm the guest cabin with a propane heater. We open and close windows and curtains to impact interior temperatures. And we have an outhouse, not a flushing toilet, so no power draw there.
We also lack many gizmos that I think are rather unnecessary, like electric can openers, bread makers, and televisions.
A few high-wattage power tools are important here because we have found no convenient alternative. Most of these function for short duration, and…
