has anyone done any research on kettles or something else? I am looking for the most energy efficient way to boil water

The last time we discussed kettles

Say yes to kettles. No to WW3

Interesting question. Here is some information:The most energy-efficient way to boil water depends on the available resources and equipment. However, here are some methods, listed in order of their efficiency:
1. **Electric kettle**: Electric kettles are generally the most energy-efficient way to boil water, as they directly heat the water with electricity and have minimal heat loss. They use around 0.12-0.15 kWh of electricity to boil 1 liter of water.
2. **Microwave**: Boiling water in a microwave is another efficient method, using around 0.15-0.20 kWh of electricity to boil 1 liter of water. However, this method can be less efficient if you're boiling small amounts of water.
3. **Induction cooktop**: Induction cooktops are highly efficient and can boil water quickly, using around 0.20-0.25 kWh of electricity to boil 1 liter of water.
4. **Gas stove**: Boiling water on a gas stove is less efficient, using around 0.30-0.40 kWh of energy (in the form of gas) to boil 1 liter of water.
5. **Electric stove**: Electric stoves are the least efficient method, using around 0.40-0.50 kWh of electricity to boil 1 liter of water.
To further optimize energy efficiency, consider the following tips:
* Use a lid to cover the pot, as this can reduce heat loss and boiling time.
* Use a pot that's the right size for the amount of water you're boiling, as this can help minimize heat loss.
* Use cold water, as this can help reduce the energy required to boil the water.
* Avoid overheating the water, as this can waste energy.
Keep in mind that these values are approximate and can vary depending on the specific equipment and usage patterns.
Thx @Anarko
there are also some (minor) differences between ‘electric kettles’, I guess, what I found so far is higher Watt and temperature adjustment is more efficient, correct me if I’m wrong
Info on shape welcome
To determine the most energy-efficient kettle, we need to consider various factors such as shape, power supply, and other characteristics.
Based on the search results, an eco-kettle that switches off immediately after boiling and has a minimum fill level is considered energy-efficient. This type of kettle allows you to limit the volume of water required and only boil the amount of water you need, which can save up to 20% in energy compared to a regular kettle.
In terms of shape, a lightweight kettle with a sleek design is preferable, as it will absorb less heat. The material and weight of the kettle also play a role in its energy efficiency, with lighter kettles being more efficient.
The power supply is another important factor. Electric kettles are generally more energy-efficient than kettles on a gas hob or microwave oven, as they directly heat the water without losing energy to the surrounding environment.
A kettle with a specific setting for boiling a small amount of water, such as 250ml, can also be more energy-efficient, as it allows you to boil only the amount of water you need.
Overall, the most energy-efficient kettle would be a lightweight, eco-kettle with a minimum fill level, a sleek design, and a specific setting for boiling small amounts of water, powered by electricity.

Plastic kettles are worse than a stove's energy waste. If there's an energy-efficient glass or metal kettle, I'd be more interested in that.
