clean electricity

Part of the Electronics glossary:

1. Clean electricity is electrical power that is free from voltage spikes and drops. Voltage ripple or noise that is outside the ideal sine waveform is sometimes referred to as dirty electricity or electrical pollution.

Dirty electricity can cause electronics to perform poorly, especially microelectronics. High voltage spikes, for example, can cause electronic component damage, both immediate and long-term, computer memory loss, program corruption and operating errors. Because electrical pollution can damage equipment and decrease the lifespan of hardware, it is a particular cause of concern for data center administrators.

The quality of electricity is influenced by everything up to and in between the electricity provider and the electronic equipment in question. An uninterruptable power supply (UPS) can help protect electronics when local power is dirty.

2. In a slightly different context, clean electricity, also known as green electricity or green energy, is electrical power produced by methods that use renewable energy resources and do not cause pollution. Clean electricity generation methods include photovoltaic solar, geothermal, wind, tidal, rain and waste heat recovery technologies.
