Lemon battery Lemon battery A lemon battery is a simple battery often made for the purpose of education. Typically, a piece of zinc metal (such as a galvanized nail) and a piece of copper (such as a penny) are inserted into a lemon and connected by wires. Power generated by reaction of the metals is used to power a small device such as a light emitting diode (LED). The lemon battery is similar to the first electrical battery invented in 1800 by Alessandro Volta, who used brine (salt water) instead of lemon juice.

Plug-in electric vehicles in the United States will be plug-in hybrids or full battery electrics by 2030. The U.S. Energy Information Administration (EIA) in its 2017 Annual Energy Outlook 2017 projected that all-electric vehicles sales in the United States will increase from less than 1% in 2016 to 6% in 2040 of total light-duty vehicles sold in the country, and plug-in hybrid electric vehicle sales will increase from less than 1% to 4% over the same period. According to the EIA projected sales of light-duty battery electric, plug-in hybrid electric, and hydrogen fuel cell vehicles will reach 1.5 million in 2025, about 9% of projected total sales
