What are efficiency and conservation?
Efficiency is doing the same thing while
using less resources to do it:
- use less electricity but cook the same thing,
- use less water but don't take shorter showers, ...
Conservation can mean the same thing
but it also sometimes means doing less as well:
- cook less,
- take shorter showers.
Usually you can be more efficient so that you don't have to do less
of what you want to.
Another way of being efficient is to repair.
An often quoted order of preference is reduce - reuse - recycle but
I'd add repair before recycle. It's amazing what people throw out
when all they'd have to do is make a simple repair. To
see how easy repairing is, click on
this collection of repairs that
have been made, some with detailed instructions
(NEW! Piano/keyboard key repair).
Efficiency examples
Rain water for flushing toilets - uses no potable water
Rather than use water specially treated for drinking and cooking
purposes,
the toilets at these public washrooms use rain water for
flushing. This saves on the unnecessary treatment as well as the
cost of pumping from the water source. These are the public
washrooms at the Vincent Massey Park in Ottawa, Canada.
Addtional features at the facility are solar power/photovoltaics for
all electrical needs, reduced electrical needs by using sunlight for
lighting, zero-water urinals and low-flow toilets.

Heat-retention cooking - uses less cooking fuel: electricity or natural gas or propane or fire wood, ...
Heat-retention cooking
allows you to cook the very same things
but use the stove less while you do it. I cook long grain brown
rice using the stove for only 10
minutes instead of the normal 45 minutes this way!

Low flow shower heads & on/off valve - uses less water and less water-heating fuel: electricity or natural gas or propane, ...
Using a low flow shower head
in place of an older shower head allows you save water while
having the same enjoyable, cleansing shower. And since
it's using less water, that also means less water needs to be
heated thereby saving fuel.
Also, by adding a simple to use
shower on/off valve
for turning the flow of water off when soaping and shampooing you
can reduce water usage down to
2 gallons/7.5 litres!

How to use a watt meter - learn about your electricity use to see where you can save
Using a watt meter
you can find out where you are using electricity and how much you're
using. With that knowledge you can make changes to save on usage.

photo or two, and they're a good fit for this page then send them
to me care of my email address at the bottom of this page and
I'll include them here. If you have a lot of details that
warrant a page of their own then see my share
