Energy at your fingertips: E.ON calculates energy generating potential of 'fidget spinners'

E.ON is always looking for innovative energy solutions so as the huge toy trend for ‘fidget spinners’ continues, it has teamed up with a group of electrical engineering students to explore the energy generating potential of the finger-operated spinning toys.

Working with electrical engineering students from Hanover in Germany, E.ON has calculated that the colourful little toys can generate power – albeit in tiny quantities.

Based on a fidget spinner turning at an average of 15 rotations per second, it would take:

  • 54,000 fidget spinners to power a standard LED light bulb for one hour

  • 1,000 fidget spinners to power a standard refrigerator for one second

  • 750 fidget spinners to power a 55” flat screen TV for one second

Although the toys are not a viable source of sustainable energy (well, not yet at least!), E.ON is exploring various technologies to help people generate electricity, such as E.ON Solar and Storage which converts sunlight into electricity using solar PV panels. The electricity generated can either be used straight away or stored in a battery to use when it’s needed, even at night.

People who take E.ON Solar and Storage could save around 30% or £180 a year if they take solar panels or around 50% or £300 a year if they take solar panels plus battery storage. People can also earn money via the Feed-In Tariff and, together, this could make users £560 better off a year; the equivalent to 80% off their electricity bill.1

Currently being offered in the Midlands, E.ON hopes to offer Solar and Storage more widely later in 2017. Anyone can have E.ON Solar and Storage installed, not just people supplied by E.ON, provided they own their home and their roof.

Homeowners can visit eonsolar.co.uk to enter details about their home, using E.ON’s calculator to work out how much E.ON Solar and Storage could cost and what they could save and earn from it.


Notes to editors

1 = These are example figures only. Savings are based on a south-facing property in central England with a 40 degree roof tilt and no shading, with a consumption of 4900 kWh. It assumes fitting 12 x 320w panels and a 9.6 kWh battery plus a deemed export of 50%. FIT rate based on figures published 1 February 2017 for a March 2017 install. Every home, area, consumption and solar panel and battery system is different so customers are urged to go to eonsolar.co.uk to find out how much they could save with E.ON’s online solar calculator. Properties with thatched roofs are unsuitable for E.ON Solar and Storage. As solar PV and battery systems vary in size, generation and storage capacity, an E.ON Solar and Storage advisor would help applicants choose the best system for their needs and for their property. The smallest size battery is slightly larger than a VCR player and a battery can be stored in most places such as a garage, utility room or even under the stairs.
