Even if coal is more expensive in Africa then solar once you include the building of the grid?

We also know from history that during those periods humans were not their. I.e those conditions are not good for humans.
I think if I recall they did build a high enough seawall, the problem was the ground fell which was not counted.
So the ISP is selling a service, then when people try to use the service as it was advertised it turns out they can't actually provide it.
I would of kept the wall as a demonstration of the patents now free.

From what I have seen sugar is much better for Ethanol in terms of EROI
From your earlier comment "But it has limits in what percentage of our supply it can produce and not cause grid stability issues"
I have shown that it can get to 35% without causing those issues .
Is the cost for spinning reserve paid for by the current power stations
Assuming power demand has not increased and thus no new plants would need to be built normally.
(I.e Wind is replacing existing instead of instead of new)
The marginal cost of coal and gas appears to be 50-80 putting the wind about equal. (And for your spinning reserve well we have gas power that is no longer running due to wind)
When you spread wind turbines out over a large area you also smooth out the variability.
The problem with allocating that cost to wind is that the other power plants do not pay for the spinning reserve.
My reading of the 6c/kwh is that includes transmission to the grid.
As for the percentage limit
http://www.aweablog.org/blog/p...
with wind farms at one point providing 35.05 percent, or more than a third, of the system's power.
It's important to note that these new marks are being set without any utility system reliability problems, as system operators make use of their standard techniques for balancing supply and demand.
You mean the same spinning reserve for large changes in demand such as the ad breaks in popular shows as people make a cup of coffee or in case a large power station has a problem and shuts down?
Integration impacts are not exclusive to wind and solar. Nearly all generators can impose costs on the power system or other generators when they are added to the power system.
These impacts are seldom calculated as integration costs and never applied to conventional generators as integration costs.

Or a broader option is to charge per CO2 emitted and use that money to reduce other taxes.
If you want an example of wind power
total cost of $0.062 per kWh composed of $0.04 production and $0.022 tax credit (or ~ £40 / MWH )
So that needs to be considered in the for column for wind.
And the benefit of dropping wholesale costs of electricity?
Waste not, get your budget cut next year.
