Very little has improved since this NRDC piece was published. It is possible to make much more efficient boxes, but even if that happened it would take a decade to replace old models installed in homes. There is no benefit to your cable company as you are paying for the electricity.
Hydrogen fuel cell EVs still have several problems - filling stations are well over $1 million per pump and extremely rare. Growth is likely to be very slow over the next five years. By then regular EVs will have fallen in price and the charging infrastructure will have improved significantly. An interesting question is how important will charging/fueling time be to a new generation who may not use cars as much. Also will people get used to a small bit of planning ahead?
Energy storage is a key to the deployment of large scale renewable energy. Unfortunately, apart from pumped hydro, grid-scale energy storage is usually too expensive. Oncor recently made a proposal for the Texas grid (there are three major interconnect regions in the US with Texas having its own grid) that makes sense by saving more than generating costs. It seems Oncor isa wires company and its scheme will save on transmission and delivery costs.
It is just a proposal at this point, but an interesting one.
Note - energy storage is usually rated in terms of the power it can deliver rather than the total energy stored. Total energy storage is usually listed, but for network operators balancing loads in real-time available power is the important metric.
Preserving coal jobs in the US is a fool's errand .. there are only 83k full time jobs in mining (0.12% of all US jobs) and 174k total (mining, transportation and power stations - Department of Labor statistics). On the other hand cycling employs over 650k people in Europe with considerable room for growth.
