The average household electricity prices in Germany were at ~29 eurocents per kWh in 2013 and they are rapidly rising 5-10% per year. The "price drop" the article describes is the drop in the electricity exchange market (EEX) prices, which indeed went down from something like 5.5 cents to 3.75 cents in the last years. The reason is the massive influx of highly subventioned solar, wind and biogas-generated electricity. At times when the renewables production spikes, the electricity is "sold" at negative prices - i.e. whoever takes it, gets paid.
For the end user, the falling market prices are pretty much irrelevant, since the end price contains the averaged difference fee ("EEG-Umlage") between the subventioned price and the market price - the lower the market price, the more the end users have to pay to get the subventioned price to the level defined by law. The more renewable energy is produced, the more they have to pay in total.
The other side of the issue is that the commercially operated conventional power plants cannot competitively operate against prices deflated by subventions, so many operators announced to scale down their capacity and close many power plants. In many cases, brand-new gas-fired plants with very high efficiency are affected, of all things, because of the rising gas prices. This however plays against the renewable energy plans, since exactly these gas-fired plants are direly needed to keep the grid stable in presence of highly fluctuating renewable inputs. Currently there are talks about introducing subventions for the conventional gas- and coal-fired powerplants in order to maintain their generation capacity. The subventions of course will be forwarded to the end user.
I've downloaded the Titanfall Gameplay video and mplayer definitely says it's 30 fps, so I'm guessing it's bullshit. VIDEO: [H264] 1280x720 24bpp 30.000 fps 3000.0 kbps (366.2 kbyte/s)
Also, even if it worked - what's the point of having a 60 fps video for a console game that can barely get 30?
The prototype tested in the Netherlands had not much success because it failed to glow properly after a rainy day (link). The issue is like with any kind of solar power - it simply does not work if there is no or too little sun.
The problem with the current leaks is that it's mostly beta radiation (from Tritium) and is quickly stopped in air, so in order to detect it, you need to measure close to the source. You're confusing it with the gamma radiation.

What you propose is about 5TWh of total storage. Currently there are 40GWh. Increasing the current capacity 125-fold is just as unrealistic as increasing it 2000-fold, seeing how a company who now tries to push plans for the 13GWh pumped storage Atdorf (http://de.wikipedia.org/wiki/Pumpspeicherkraftwerk_Atdorf#Pumpspeicherkraftwerk_Atdorf , sorry, no English version) has been struggled for years with their plans, primarily against the opposition of the Green party.
So your plans is to build a ~30-by-30 kilometers sea that is elevated by 100 meters. Do you even realize how giant this thing is? It's the size of Berlin! Do you realize that you also need to multiple it by 2, since you also need a sea at the low level to store the water?
80TWh will never happen, and 5TWh won't happen either, and 1TWh is maybe realistic within 200 years or so. The renewable revolution will not happen, all we're doing now is going back to burning lignite and gas.
1) This storage capacity was calculated by simulating wind, solar etc. output based on real weather data. It already assumed a realistic mix of renewables including ones with adjustable output such as biogas and a realistic possibilities of export/import.
And about "firing up fossil plants for a few days in a year". Just imagine what would any electricity company do if they had a power plant that they would be able to use only a few days a year? They would immediately close and dismantle it and fire the staff, because the maintenance and standby costs would dwarf any profit from it.
Actually, this effect can already be seen here in Germany. We're far away from 100% renewables, yet in the wake of closure of several NPPs, and the ever increasing demand for backup power because of growing renewable supply, there is a huge debate about building additional coal and gas power plants. One would guess there's a gold rush building these? Nope. The major electricity producers already said that unless they can fire them close to 24/365, there's simply no profit in building them. The government would have to do the despicable and actually start subsidizing coal and gas power plants if they want a stable supply.
2. Solar might have a generation curve that matches the daily consumption. But seasonally, it doesn't match the consumption at all. The season of the peak consumption in Germany is WINTER, because of less natural light and warmth. At the same time, the solar production is very low in winter, it falls way below 5% of what it does in the summer. It's the saisonal fluictuations that need the storage, not daily.
3. This list is obviously bullshit. It lists Germany with THE AVERAGE PRICE of 27 $ct/kWh. it's like 21.5 euroct/kWh. I'd like that price! Where can I get it?
If you look at verivox.de, there's a price calculator at the top. You can enter the postal code (try 10000-13000 for Berlin) and your expected consumption to get the cheapest tariffs. The cheapest one I get is 411 euros for 1700 kWh a year. That's ~30 US-cents/kWh in the current conversion ratio. However it's a prepaid package which everyone would recommend to stay the hell away from. Last year a major "cheap" supplier suddenly went bankrupt and many people lost their prepaid electricity packages. The average prices are much higher, typically around 26-27 euroct/kWh.
About the taxes: the major factor is in the recent price increase in Germany was indeed a tax - a sort of a tax that is levied on the electricity consumers and used to pay the renewable electricity producers.
4. Well, guess what? Germany is a couple of hundreds kilometers long. Yet the wind power manages to fluctuate between near zero and the maximum all the time!
Oh, and about pumped storage: yes, it's the most cost-efficient storage method, but for the dimensions we are talking about, it requires too much space. For comparison: currently available pumped storage in Germany is 40GWh. In a regenerative 100% scenario, 80TWh would be required, the 2000-fold increase. Currently, there is a plan to build another storage sea with 14GWh, it's been in planning for the last 15 years and is currently confronted with massive lawsuits from the public who want to stop the project at any cost (nobody wants to have a huge concrete sea in their backyard), so it's anything but certain if it ever is going to be built.
1. the household electricity consumption is only a minor part, the most is consumed by the industry, and you need to provide storage capacity for them as well.
2. The regenerative power like wind and solar is subject for a major saisonal fluctuations. Which means, the storage needs to be able to load all the energy during one season with high production and keep it for months so you can use it in a season with low production.
3. Currently, Germany is in a "20% scenario". We already have the highest electricity prices in the world (for a major country) ~26 âct/kWh and the import/export saldo in the area of 15% of total production. The electricity prices will likely increase by another 3-4 cents next year and so far there's no end to the price hike in sight.
In Germany, the electricity production/use is ~7500kWh per capita, so 1MWh storage is sufficient for just about 50 days. Considering that the assured production of wind power is below 1% (that is, 200MW in the entire country with over 25GW wind turbines) of installed capacity at 99% of assured supply (that would mean 3.5 days of blackout per year on average, in reality we have only ~15min, or 99.997% assured supply here), it's not that astonishing at all.
It was his own mistake to take the Vision Enhancement as his first augmentation. Should have chosen Microfibral Muscle or at least Speed Enhancement first.
Normally, CAESes, such as the on operating in Huntorf in Germany, IS burning natural gas. When storing energy, the air is pumped into the caverns. When extracting it back, the air may just turn the turbine directly, but this way, a lot of energy will be lost - the pumped air storage is tightly sealed, but the compression heat is inevitably leaking from the cavern.
What they normally do instead - they use compressed air as the input for a turbine burning natural gas - this way it does not need it's own compressor, making it more efficient than a conventional turbine. From 0.8kWh of stored electricity and 1.6kWh (thermal) of natural gas, they produce 1kWh of output electricity. Burning 1.6kWh gas in a normal turbine with 50% efficiency would produce 0.8kWh electricity, so the overall efficiency of this storage is just about 50% - or even less if you consider more efficient gas-and-steam power plants. Maybe this new CAES will utilize some more efficient technology, but don't expect wonders from it - this type of storage has quite high losses.
The CAES were never about storing power efficiently, their main advantage is the ability to power up really quickly. The Huntorf CAES for example is able to reach 50% output in just 3 minutes, and full output in under 10 minutes.
How about "Someone just blew up the nuclear reactor near the city where your family lives", would that be more in the same level of shock and terror?
Besides, Israel itself has described cyberattacks as terrorism.
All these "net zero" concepts are non functional without a grid, because they need it as a storage and they don't implement their own storage. And they assume this service is for free.
While such installations are rare, the service is indeed free, but the question is whether this concept will survive on a large scale - no it will not. If the amount of renewable energy increases and everyone just keeps using the grid as a free storage facility, the grid operator will have to invest more and more to extend this storage capacity. This includes maintaining of the true storage like the pumped water but also maintaining backup generation plants and transport capability. Other negative effects include lesser profitability of the conventional plants.
Sooner or later, this will require offloading of the additional costs to the consumers. Sooner or later the "net zero" facilities will have to pay additional fees for using the storage capacity of the grid provider.
Currently, this is what we see looming here in Germany - increasing amount of renewable energy while at the same time attempting nuclear phaseout leads to funny effects - the transport capacity of the one of the best maintained grids in the world are at limit and need massive investments. On the other hand, more gas power plants are needed to be built to be able to compensate random production - but they are getting less profitable. The effect is - the grid providers are currently pushing proposals for additional assessments on electricity - the consumers will soon have to pay additional fees for supporting extension of the grid infrastructure and for subsidizing of new coal and gas power plants. Either this be passed as law, or the providers simply increase their prices - either way the costs of the renewables have to be compensated and our already highest electricity prices in Europe and likely worldwide (currently ~27 eurocents/kWh on average) will skyrocket even further.
Actually, the average household electricity price in Germany is already at ~0.33 $/kWh, and it will likely increase by another 3-4 cents next year. So, we are not that far away from your figure.
Guys, listen, I have an idea! You won't believe it, guys! Guys?
So, like, what if we just make coins with a value of $0.99? This way, you can directly pay $x.99-type prices and won't need pennies at all!
