What is Electronvolt?

The electronvolt is a unit of energy widely used in particle physics and quantum mechanics. It equals the energy gained by a single electron accelerating through a potential difference of one volt, approximately 1.602 times 10 to the minus 19 joules. Visible light photons have energies of about 1.8 to 3.1 eV, X-rays range from a few keV to hundreds of keV, and particle accelerators work with energies of GeV to TeV. Semiconductor band gaps are also expressed in eV, with silicon at about 1.12 eV.

What is Kilowatt-hour?

The kilowatt-hour equals 1,000 watt-hours and is the standard billing unit for household electricity. An average Japanese household uses about 300 kWh per month, and electricity costs roughly 25 to 40 yen per kWh. Electric vehicle batteries range from about 40 to 100 kWh, providing approximately 6 to 8 km of range per kWh. Solar panel output is also measured in kWh.
