Renewables are not renewable :-)

With the current stete of technology, there is no way they can take over
traditional generation. Still,that is not the point. Neither is being more
ecofriendly, because solar is polluting as heck and airgenerators consume
resources that are no renewable.

The point is anybody wealthy enough to set his how power generation will be
able to make a dent in his power bill and recoup the investment in human time.
Bonus points because if there is a disruption in the Energy supply chain (ie.
WWIII) you will have a limited supply to cling to during the crisis.

Certainly, most solñar I see deployed today are cheap investments intended to
reduce the power bill rather than serious deployments intended to make a house
slef-sufficent or close to self-sufficient. Of course, we are talking about
domestic power generation, but here is this:

* Estimated budget to make my house energy self-sufficient on solar only: 30k
EUR
* Estimated budget to make my house self-sufficient 92% of the year: 18k EUR.
* Typical deployment for similar homes in my area: 6k EUR. (which makes you
self-sufficient less than 25% of the year).

The Government'splan for the transition of energy productivity is to have
people install the latter: that way, solar systems will produce energy around 6
hours per day, with all excess power sold to the power grid. Then, owners of
solar systems will purchase power from the grid during non-productive hours at
a discount. The idea is that you compensate the energy you are forced to buy
with the energy you poured in the grid when you were having excess - that way
they tell you you don'tneed to invest in batteries, which are the single most
expensive element).

Sadly, that setup is quite lame because it ends up meaning that the owner
invests 6k EUR, has power during 6 hours per day, and then gets to buy the
defficitary energy by night at a 30% discount (and only a small fraction of the
energy purchased comes with a discount, actually). IN other words: it is a
scam.


Power companies don't want you to have batteries because they want you to sell
them cheap energy instead and then sell you expensive energy. I think a lot of
the FUD against batteries comes from this.
