to an ultra-fast, high-capacity class of computer memory known as magnetoresistive random access memory, or MRAM.
The UCLA team's improved memory, which they call MeRAM for magnetoelectric random access memory, has great potential to be used in future memory chips for almost all electronic applications, including smart-phones, tablets, computers and microprocessors, as well as for data storage, like the solid-state disks used in computers and large data centers.
MeRAM's key advantage over existing technologies is that it combines extraordinary low energy with very high density, high-speed reading and writing times, and non-volatility — the ability to retain data when no power is applied, similar to hard disk drives and flash memory sticks, but MeRAM is much faster.

Journal of Power Sources has a paper "Cost-minimized combinations of wind power, solar power and electrochemical storage, powering the grid up to 99.9% of the time".
NBF -
This actually looks like a more credible and realistic plan.Tbhis is basing analysis upon the crappy plans by Stanford's Professor Jacobson.
This plan looks like it could be worth some further consideration.General limitations are I doubt they consider any economic growth that would require more power (it assumes you stay at the current energy requirements). I would also like to see how they are handling the power grid costs and if the grid is in the right places. Usually renewables need more power grid extensions which are costly and time consuming.
UPDATE -
Found a copy of the full report.
They propose building by 2030
124 GW of the needed power from inland wind.
89.7 GW of the needed power from offshore wind.
16.2 GW from solar
51.9 GW battery storage
Of 91.3 GW produced power average.
50.3 would be from the inland wind
38.3 would be from the offshore wind
This looks like it would cost a lot more than building nuclear power or some other mix of power generation. This is a link to the EIA levelized cost of energy.
It looks like this approach would cost about 2 to 3 times more than a mostly nuclear power approach.
They modeled wind, solar, and storage to meet demand for 1/5 of the USA electric grid.
► 28 billion combinations of wind, solar and storage were run, seeking least-cost.
► Least-cost combinations have excess generation (
3 times the load), thus require less storage.
► 99.9% of hours of load can be met by renewables with only 9–72 h of storage.
► At 2030 technology costs, 90% of load hours are met at electric costs below today's.
They use widespread geographical distribution the intermittent sources (wind farms and photovoltaic installations) all parts of the grid would have enough power. (windy and sunny in come parts to make for calm and overcast areas in other parts)

In Saudi Arabia's own direct communication to OPEC, the kingdom said November production was lower, at 9.49 million. The November Saudi amount was 550,000 barrels per day less than in August.
Therefore, Saudi Arabia appears to have cut back its oil production to 11.2 million barrels per day in the last week of November (in order to support a higher price for oil because of higher USA and Iraq production increases). The US increased oil (crude oil, natural gas liquids, ethanol and other liquids and refinery processing gains) production to pass Saudi Arabia in the first week of December (to 11.33 million bpd). The USA added 660,000 barrels per day since August.
11.33 million bpd for the USA and 11.2 million bpd for the Saudi Arabia swing producer. The USA became the number one oil (all liquids) producing nation in the first week of December. Based on simple math and what Saudi Arabia announced and what the USA reported via the Energy Information Administration.
Total Oil supply for the US for the days in the Week ending Dec 7 was 11.33 million barrels
