I'm always reluctant to recommend large scale solutions relying on lead acid

The adverse environmental impacts of plants that process them are huge, 
contaminating nearby communities with lead emissions for which there is no safe 
exposure.

Lead can certainly be bad for people and the environment. But then, so can the materials in just about any battery.

The key lies in *responsible* manufacturing, handling and recycling. Lead-acid batteries have been around so long that there are laws and procedures (in most developed countries) that prohibit bad practices. Upwards of 98% of the lead is recycled into new batteries. No other battery comes close. The majority of them are (sadly) thrown out as trash and wind up in landfills.
