BNEF predicts that lithium-ion battery prices, already down by nearly 80% per megawatt-hour since 2010, will continue to tumble as electric vehicle manufacturing builds up through the 2020s. trillion of that going to wind and solar and a further $1.5 trillion of that going to wind and solar and a further $1.5 NEO 2018 sees $11.5

In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. Out of Finland’s energy-related emissions, 82 percent come from heating domestic buildings (Ref. There is nothing special here!”

The biggest leap forward happened in 2012 when it was discovered that USB stick TV tuners using the RTL2832U demodulator chip could be tapped to make very cheap but effective SDR receivers. Building off the demand stimulated by this activity, a number of manufacturers have started making premium, but still relatively cheap, SDRs.

At the time, e-bikes were still rather exotic, at least in the United States, so it seemed worth the expense and effort to build my own. Online discussions convinced me, however, that this is the expected behavior when commanding a motor to maintain a fixed amperage in its windings (thus applying constant torque) while under little load.

The magnitude of these savings is ~5% to 15% higher in a system with 20% wind penetration compared to a system with no wind power, and the savings are 50–60% higher in a system that requires capacity expansion. Controlled charging can also take advantage of the high levels of wind generation that commonly occur at night in the US.

The report goes on to model the impact of this on a global electricity system increasingly penetrated by low-cost wind and solar. In the near term, renewables-plus-storage, especially solar-plus-storage, has become a major driver for battery build.
