A complex dilemma you've painted.
But it's all in the (your) mind :)

Yes renewable energy seems to cost more than conventional fossil but then the last has hidden costs regarding the environment now and in the future.
I'm really curious why you brought up the subject of trees, do you maybe feel we need to cut down trees for large scale PV deployment?

Like yesterday I ordered PV cells covering about half my garage roof and they'll be good for some 125% of my annual consumption and that's at 52 degs. North.
A few hundred square kilometres in some nice deserts (+ a lot of transmission infrastructure) would cover the needs of the planet.

South Africa doesn't need electrical water heaters, solar boilers on rooftops can supply all the hot water a family or hotel needs, have a look in places like Italy and Greece.

But there's just this little thing you guys aren't allowed to import the necessary vacuum tubes needed for the solar heaters, the tax man vs. the environment!

Or, see it as a business opportunity and start fabricating them in the country.

In the 80's I worked in Saudi Arabia and we already had a solution to this issue.

With proper sizing that top tank will sufficiently cool off during the night, in the morning you start by switching off power to the water heaters, then take a shower the regular way.

This way the heaters will be filled with cool water from the tower and at night when returned from work in the desert we'd take a shower with cold water from the heaters and warm water from the top tank.

Now switch the heaters back on to prevent the freshly entered hot water from cooling down overnight.

You've clearly not been living in the EU.

Or you've for the past ~15-50 years been living under a rock.

Had you not been living under said rock and like me been travelling the world and the EU you would have had first hand experience of the vast steps forward we've made.

Oh yes, because you live under a rock you've likely not heard the populists in France and Denmark are after the recent attacks by domestically bred terrorists keeping VERY quiet with their stale demands to close the borders to keep out trouble.

Maybe you should take your temperature?

Nearly every EU country has a couple of conspiracy nuts claiming *.* screwed them during or before unification.

The problem is not someone loaned bad or good money to Greece, the problem is Greece wasn't and isn't able to hold up it's own pants, all due to their own lack of courage to fix their tax and economic imbalances.
