Shenzhen's silent revolution: world's first fully electric bus fleet quietens Chinese megacity | Cities | The Guardian
Shenzhen now has 16,000 electric buses in total and is noticeably quieter for it. “We find that the buses are so quiet that people might not hear them coming,” says Joseph Ma, deputy general manager at Shenzhen Bus Group, the largest of the three main bus companies in the city. “In fact, we’ve received requests to add some artificial noise to the buses so that people can hear them. We’re considering it.”

The benefits from the switch from diesel buses to electric are not confined to less noise pollution: this fast-growing megacity of 12 million – which was a fishing village until designated China’s first “special economic zone” in the 1980s – is also expected to achieve an estimated reduction in CO2 emissions of 48% and cuts in pollutants such as nitrogen oxides, non-methane hydrocarbons and particulate matter.

A Nation-Sized Battery | Do the Math
Putting the pieces together, our national battery occupies a volume of 4.4 billion cubic meters, equivalent to a cube 1.6 km (one mile) on a side. The size in itself is not a problem: we’d naturally break up the battery and distribute it around the country. This battery would demand 5 trillion kg (5 billion tons) of lead.
Get the Lead Out!

A USGS report from 2011 reports 80 million tons (Mt) of lead in known reserves worldwide, with 7 Mt in the U.S. A note in the report indicates that the recent demonstration of lead associated with zinc, silver, and copper deposits places the estimated (undiscovered) lead resources of the world at 1.5 billion tons. That’s still not enough to build the battery for the U.S. alone. We could chose to be optimistic and assume that more lead will be identified over time. But let’s not ignore completely the fact that at this moment in time time, no one can point to a map of the world and tell you where even 2% of the necessary lead would come from to build a lead-acid battery big enough for the U.S.
