How is this anything but good?
1. Africans should get energy? Yes they should, and this will help enrich the region, at least more than if this were not built.
2. Cables are a terrorist target? Yep. So are a lot of things. Diversify.
3. I thought Europe was already green? No, and this won't make it 100% either, not by itself. But it'll help.
4. Only enough to power Ireland? True. Better than NOT building enough solar to power Ireland.
5. Unfair to Tunisia/Unfair to Europe? No. Trade is good. Tunisia can produce energy cheap, and Europe has money to buy it. Capitalism at its finest.
6. We don't want energy dependency in that part of the world? True. Nor do we want it in any part of the world. Diversification again is key. Here's a way to diversify: get some solar from Tunisia. Bad idea: get most energy from Tunisia. Or most from fossil fuels, for that matter.
7. Local energy is better and conservatives would like that? Local IS better ... and elitist, like eating local. The poor person who can't afford it?
Political, rant against both sides for lack of common sense:
Conservatives like to drill-baby-drill, but since we don't have that many fossil fuel reserves, the remainder would have to be US renewable or imported cheap fuel. Conservatives choose imported cheap stuff every time, reducing our security for a modest decrease in price. In fact, we have our own deserts where, with some modest grid improvements, we could get cheaper, cleaner, domestic energy, better in every imaginable way, but the right does not want that (because the left does). And the left has trouble encouraging nuclear. Nuclear DOES have issues: waste and safety, both of which can be dealt with. There's another issue: nuclear power plants might not be competitive with wind at this point. If that's so, and if the left doesn't like nuclear, then they should be screaming FOR nuclear. The nuclear wouldn't get built (energy companies won't build anything uncompetitive) and the left would look like patriotic heroes for trying. Or at least they'd look consistent on the issue of carbon emissions. And if nuclear plants do get built because they can be built safely and are economical ... that's good! I HOPE that happens.
Everybody with a brain should admit the facts:
* Global warming is real. The physics are trivial -- read a book from say 50 years ago about Venus' atmosphere to get a non-political understanding of the mechanism and devistating inevitability of the problem. It's real. Don't change the facts to fit your theory. If your doctor told you that you had cancer, you wouldn't wait for treatment until you really needed it. You'd attack the problem early, because waiting is stupid.
* The solutions go beyond your ideology, left or right. Remember Acid Rain? Republicans and Democrats argued but eventually came to a market-based approach, and the problem was solved for dirt-cheap. The problem was liberal (the environment actually matters), the solution was conservative (market forces), and the world is now better off. Ozone hole? The problem was universal (skin cancer), the solution kind of liberal (international agreements) and again for a minimal price the problem has turned the corner and will be fine in a while. Everybody needs to quit whining and just take care of the problem. It's not that big a deal, especially at current renewable prices. Conservatives need to contribute their voice, to put forward proposals that actually solve the problem but without silly liberal baggage, and after some ridiculously ugly compromise, we'll solve the problem, it won't be that expensive, and like acid rain or lead in gasoline or ozone layers it'll be a boring thing of the past.
