In theory it's sound but in practical terms, it's very difficult. The author is a bit disingenuous by saying there's a lack of political will. Imagine if politicians here said we'd build all of the above but in the meantime they'd have to double the energy costs to pay for it?! There'd be bedlam.
But, in the meantime countless non-renewable plants will have to be built. Should the money not be better used on projects like this?
I don't see it as a likelihood that this will happen, however I don't see why it can't be aimed at. And ambitious targets are the way to go! Achieving 50% of 10TW > achieving 85% of 5TW

Not unless they're cost effective. However, if research institutions wish to invest time and money in them, they're more than welcome to.
I feel very strongly against any sort of industry being heavily subsidized so renewable technology shouldn't be exempt from this, what could be deemed harsh, point of view.I don't see it as a likelihood that this will happen, however I don't see why it can't be aimed at. And ambitious targets are the way to go! Achieving 50% of 10TW > achieving 85% of 5TW
I definitely agree with this sentiment though! 0 -

Without wanting to get this dragged into another wind thread, isn't wind energy cheaper to generate? (At least at decent windspeeds). And isn't it Eirgrid's aim to have 40% Wind power by 2020 anyway? (source)
Oops, you just have!
The problem is the cost of building the wind farms - it costs approximately €1.8m to build a 2MW turbine and connect it to the grid.
After that, you have maintenance costs.
However, it's only generating power approximately 28% of the time.
So, comparing it to a 750MW power station, the turbines cost a bit more and you still need the back-up generation.You wouldn't happen to have the average cost per kW/H for the different types of generation handy (It's eluding me on google!)
You won't find prices like that very handily on Google.
However, I'll see if I can dig up MWh prices tomorrow.0 -

Oh No!
Well I know that this feasibility study is for worldwide generation. I'm not 100% how it deals with smaller countries like Ireland - presumably massive interconnectors are part of the deal!
So negate back up generation for a minute! Now day to day maintenance of a windmill is surely cheaper than maintenance of a power station + fuel costs!You won't find prices like that very handily on Google.
However, I'll see if I can dig up MWh prices tomorrow.

it means you could power the EU with panels covering a small area of a saharan country
Not quite a map, but....
Might as well have the rest:
