Two tenths of a percent of the world is Jewish.

That means for every Jew, there's over a hundred Christians, over a hundred Muslims, around seventy Hindus, thirty five Buddhists,

This does not make any sense at all.
Either there are two tenth jews on the planet, than it is every 5th ... or it is a low percentage.

Make up your mind.

We have to wait until idiots like you understand that this has nothing to do with "islam" or religion at all; but is a political thing of power games, mislead jobless/hopeless/future less/uneducated idiots who easy follow "free speech" advice to fight "change" (threatening the mighty). It is exactly the same stuff that happened in pre Nazi Germany, leading to the rise of the Nazis.

Europe had its most peaceful "Enlightening" periods when it was ruled by Islamic rulers ... after the Reconquista (http://en.wikipedia.org/wiki/Reconquista) it dropped back into barbarism right after it.

You seem to forget that nearly everything that was discovered and researched before Einstein is basically asian, arabic, islamic etc.

The number of christian philosophers e.g. is rather slim: http://en.wikipedia.org/wiki/C...

Well, to answer your question: we have to wait till people stop to exploit other people. All this bullshit going on in the world is about money and exploitation. Nothing has anything to do with any religion.

Actually, it would not.

The islamic religion is besides popular unbelief very similar to the christian one.

Actually it is an "artificial" religion crafted with the jewish and christian religions as templates in mind. Established in a region of Africa/Arabia where every tribe had its own gods and religions.

Everything that you might believe brings you into hell or heaven in christianity does the same in islam ... perhaps you have not realized yet: moslems believe in the same god as jews and christians do. Allah is just the arabic word for God.

Also they did not seceed. When the brits gave up India, the contract giving India and Parkistan independency defined the breaking up right away.

Pakistan has no Sharia law, but more or less the old british law system.

Tge spin up times are irrelevant.

Relevant is: the coal plants that only can adapt in steps and can not like a gas plant adjusted arbitrarily: they already exist.

Hence you have costs in running them, especially in overproducing.

There Re two kinds of peaks, the daily high demand on the grid, and the continuous variation around the last minutes average.

Your plants have to adapt to that variation in seconds, not minutes. That is what pumped storage is doing. And that is what batteries can do, too.

Regarding efficiency there is not much to expect from new solar panels anymore.

The only thing you can do is combine several technologies, to gather light in several wave lengths.

A typical mono crystalline PV cell might improve by 1% ... perhaps ... however the future gains will likely be in cheaper production, not in efficiency gains.

Other gains are paint based solar cells, that can be painted on houses. So far they have low efficiencies, around 1% to 5% ... but they don't look like PC modules and can be painted everywhere.

You can add a smart meter.

Then you constantly either load or discharge the battery during peak time and balance the grid.

Actually you would sell this "option" so that a balancing power provider can put you and your neighbours who do the same into a virtual balancing power plant.

Now if the grid needs an excess 5MW you and your 49 neighbours in the same virtual balancing power plant will each provide 100kW power.

Supposed your battery has like 1MWh storage (just for easy calculating, likely you only have half of it)

As you likely will provide something like 25% of the day time either loading capacity or discharging capacity, you provide 6h every day where your battery is either loading with up to 100kW or discharging with up to 100kW. Lets assume it is on average only loading/discharging with 50% of its peak. So we have 6h with 50kW "load", that translates into 300kWh of balancing energy.

For that you would charge the grid operator a fixed fee something like 2 EURO per day to provide the option to use the battery as balancing power plant. Option means: he pays you minimum that fee regardless if the grid operator actually needs the balancing power or not. On top of that you charge the grid operator depending on how your "virtual power plant" is marketed by the "balancing power provider" up to 40 cents per kWh.

That means on a good day (won't be many like that) your battery makes you 120 Euro, per day.

See: you look at it from the complete wrong perspective, oops, forgot the extra 2 Euro base income.

As I said, the 1MWh storage might be exaggerated, so size the earnings down accordingly. Also balancing power usually costs in the 10 to 15 cent range, and not the 40 cents proclaimed above. However if you can participate in a virtual balancing power plant with a mere 1MWh installation (10kW - 100kW power) you easy make a few thousand Euro money per year!

Actually the money you earn if you provide "balancing energy" is usually much higher than the money you get for feed in tariffs.

And keep in mind: balancing goes in both directions: sucking up surplus production balances as much as providing extra energy when demand is increasing.

PV can only provide power into one direction and as it is not dispatch able it can not really balance the grid.

However bigger PV installations have a notice able electric capacity, and can be used to stabilize the grid frequency to a small extend.

The energy is not generated cheaply at night. It basically costs the same. (The idea when to charge batteries is a misconception on /. You charge during peak times, see below.)

That peak energy is expensive has not much to do with generation pries, but with grid logistics.

Consider you have a load following coal plant running at lets say 75% during a peak period, does not really matter, lets say a random time between 10:00 and 17:00 (5PM for the americans).

Now for some reason you get an extra load on the grid, which you can not fulfill, so you have to increase yield of the above plant. Unfortunately you can not adapt your plant to the exact demand, the coal plant can only change its yield in lets say 2.5% steps.

So after you have increased the yield you are producing to much energy. So actually you burn more coal than you need to fulfill the demand.

Either you have to sell the extra energy, store it in a pumped storage or let it go to waste in a resistor at the power plant.

Regardless what you chose: it costs the energy company. Hence they demand a premium price for peak times.

The closer the plants are running at the exact demand of the grid, the more likely it is they mainly create costs instead of revenue when they increase their yield. Or when demand suddenly drops!

That is where smart meters and batteries or EVs come in
During peak time, when energy is supposedly expensive, charging batteries will prevent that problem. Hence smart meter owners with storage capacity will mainly charge during peak times, and not off peak, for a special low price, not for an expensive price.

Of course you are not simply charging constantly during peak times. The power plants or the grid operators will remote control your charging, so they can "balance" the grid with your batteries instead of using pumped storage or wasting the energy.
