The EU directive forcing lower wattage devices will mean a bigger carbon footprint, long term.

In California, they introduced severe anti-pollution legislation, for cars.
This forced manufacturers to reduce their exhaust emissions, ending the unhealthy smogs that be-devilled their major cities.
This was a great victory for Green activism, which other’s have constantly striven to emulate.
The EU’s directive on vacuum cleaner power sizes is a poor cousin of this triumph, which is unlikely to achieve the desired effect of keeping homes clean and reducing the need for fossil fuels (an admission that we will remain reliant on them, until alternative forms of energy can synchronise supply with demand).
The nature of vacuum cleaner design is such that effective, lower power devices will rapidly wear, losing effectiveness and requiring more frequent replacement (greater waste implied).
This view has as much evidential support as the proposed legislation and, so, is open to dispute.
The case for reducing the power of kettles is, however, a complete nonsense and must be a misrepresentation of EU intent.
A fixed amount of water requires a fixed amount of heat energy to boil. As the electrical energy for a kettle is intended solely to heat the water, the only way to waste energy is by heat escaping into the room.
A low power input would mean that it would take longer (Power = energy per second) to boil the water, meaning that more heat will escape into the room.
[Rate of loss of heat depends on temperature difference (kettle v room) and intervening insulation.]
Creating kettles with sufficient insulation to offset the extra time required would mean such devices would be too bulky for most purposes.
The need to prevent explosions through a build-up of steam pressure would require materials with the strength of metal, further increasing structural costs etc.
People will find it easier to return to old style gas kettles, or use pans to boil water.
This pandering legislation will be circumvented and cause the greater waste of time and energy that the electric kettle was invented to overcome.
