1st the maintenance and replacement costs would subtract from the profit. So the $5/hour is pure profit.

2nd how do you go from $10/hour profit by yourself to $15/hour($10 to the employer + $5 to you ) profit when you hire people

3rd the extra $580/hour does not disappear but stays within the company building a savings.

Comment Re:Dang, four times as expensive! For solar subsid (Score 1) 1030

Most of the extra cost is the grid was predicted to use a lot more then was used. So the grid has to payback the investment,

From the $54
$27.50 network costs
$10.80 energy efficiency (and FITs which does not effect the cost of purchasing)
$10.80 to generate the electricity
$4.86 Carbon Tax.

Here in Australia if you use 1.5kw for 4 hours a day you would pay $54

Using a 10 year 8% loan that repayment would be $4000

http://www.lowenergydevelopments.com.au/1.5kW-Complete-Installation-Kit-Tin-roof-Tilt-Frame is 2,750 leaving $1000 to pay for installation.

That is assuming you have 1.5kw of usage for the 4 hours during the day for solar to offset.

The most noticeable thing I notice about your scenarios is electricity is not the biggest problem. And the most common is 1 in a 1000 years,

Given the wind is now one of the cheapest forms of power, using wind to power CO2 sequesters is probably a good match. Especially because you do not need base load for it. If you can turn the sequesters off quickly it is even better.

Or you use the wind electricity to make hydrocarbons.

Interesting you say volcanic dust could shut down solar. Despite at least two volcanoes shutting down a large part of air travel I have not seen any indication of solar panels being affected

How can they be sure the sun reduction will not lead to an Ice age?

They have looked at how much the reduction is predicted (in the worse case) to be and how much the CO2 increase is predicted to be.

And months of storage does not mean much compared with 70-300 years.

What happens when the remote mines get hit by the elements?
