To environmentally friendly clean a burnt oven, you can start by creating a paste using baking soda and water. Spread the paste over the burnt areas and let it sit for a few hours or overnight. Then, use a damp cloth or sponge to scrub the burnt areas. You can also use a mixture of vinegar and water in a spray bottle to help loosen the burnt residue. Finally, wipe down the oven with a clean, damp cloth to remove any remaining residue. This method is effective and environmentally friendly, as it does not involve harsh chemicals. **

The electric lawnmower may not be turning properly and smelling burnt due to a malfunctioning motor or a damaged blade. The motor may be overheating, causing the burnt smell, and the damaged blade may be causing the mower to struggle to turn properly. It is also possible that the mower is being used on excessively thick or wet grass, causing strain on the motor and resulting in the burnt smell. It is important to inspect and potentially replace the motor or blade, and to avoid using the mower on overly challenging terrain. **

An electric kettle is generally more sustainable and environmentally friendly compared to a stovetop whistling kettle. This is because electric kettles are more energy efficient, using less electricity to heat water compared to the stovetop kettle which uses gas or electricity. Additionally, electric kettles have an automatic shut-off feature, which prevents over-boiling and saves energy. Furthermore, electric kettles are often made with materials that are easier to recycle, making them a more sustainable choice. **
