Efficient
The things we buy and use should perform their task without the need for disproportionate amounts of time or energy. Some products – eg washing machines and fridges – come with a rating that tells you how efficient they are in their use of energy.
Equally there are some things that we are sold that use electrical or other power where ‘elbow grease’ would be as – if not – more effective. For example leaf blowers which blow leaves around as a way of clearing them, whereas a brush would do the same task with no additional energy other that our own muscles.
