The Christian Science Monitor reports on legislation proposed by Republican law-makers in Wyoming:
The bill would require utilities to use "eligible resources" to meet 95 percent of Wyoming's electricity needs in 2018, and all of its electricity needs in 2019.
Those "eligible resources" are defined solely as coal, hydroelectric, natural gas, nuclear, oil, and individual net metering.
The latter would encompass houses (and businesses?) with solar, wind or co-generation equipment. Utility-scale generation, however, could face a $10/MWh penalty.
The article notes that
Wyoming is the nation's largest coal producer [...] nearly 90 percent of the electricity generated in Wyoming came from coal in September 2016, the most recent month with available data.
A PDF of the bill, SF0071, is available on the Wyoming legislature's Web site.

> I've even seen a proposal using Zinc-air batteries.
Someone has written about it in Wikipedia:
The Eos Energy System battery is about half the size of a shipping container and provides 1 MWh of storage. Con Edison, National Grid, Enel and GDF SUEZ began testing the battery for grid storage. Con Edison and City University of New York are testing a zinc-based battery from Urban Electric Power as part of a New York State Energy Research and Development Authority program. Eos projects that the cost of storing electricity with such EOS batteries is US$160/kwh and that it will provide electricity cheaper than a new natural-gas peaking power station. Other battery technologies range from $400 to about $1,000 a kilowatt-hour.
