"Non-electric" refers to items or systems that do not require electricity to operate. This can include tools, appliances, and devices that function through manual effort, mechanical means, or alternative energy sources. Examples of non-electric items are hand-cranked coffee grinders, manual can openers, and solar-powered calculators. In many cases, non-electric solutions are preferred for their simplicity, reliability, and independence from power sources. They can be particularly useful in remote areas or during power outages. Additionally, non-electric devices often have lower environmental impacts, as they do not contribute to electricity consumption or require batteries, making them more sustainable options.
