This is pragmatic follow-up part C for episode 2 the battery problem. I'm Ben Alexander and my co-host is John Gigi. Thanks Ben
Wanted to talk specifically about some feedback from gentlemen by the name of Lenny P
Robert and on Twitter he sent through some very interesting links to
situation in Germany in Europe with respect to
The renewable energy situation over in in that country and in parts of Europe as well
Now, the links for these are in the show notes for this follow up segment.
And what's interesting is that for those people that don't know, Germany actually led the way in a lot of respects with regards to renewable energy.
And the Renewable Energy Sources Act came into force in 2000.
And it was written a few years before that, but it came into force in 2000.
And amongst a whole bunch of other things that guaranteed feed-in tariffs, one of the problems that we had here in Queensland was that the government set in the feed-in tariffs at a very attractive rate.
And then after the uptake, the initial uptake after a few years, they realised that they were unsustainable and then they cut them.
So they said, if anyone who's on the existing tariffs will give them to you for a bit longer, but they could end them at any point that they choose.
any new people signing up were down to 8 cents. So we got I
signed up on 8 cents kilowatt hour feed in whereas originally
it was I think 40 or so it was something ridiculously high. And
anyhow, so a lot of people put in small systems and were able
to get away with offsetting their energy costs for not a lot
of money. Whereas in my case, I've had to put in a five
kilowatt system, which is the largest allowable in order to
get those sorts of trade offs. But in any case, either way,
either way you want to look at it in Germany, they figured this out, you know, and implemented an act into law a long time ago. So over getting close to 14 years ago now. So what that has driven has been a massive explosion of development in solar and in wind and the solar power capacity, for example, the current installed base of the 2013 is 35.6 megawatts of
solar generating capacity. And in addition, wind power is 32
gigawatts of capacity that's onshore. And in addition to
that, they're developing offshore wind generation. One of
the ideas of doing offshore is that you can have a pylon out to
sea where there's, it's not it's either too shallow to be a
shipping channel. Or, for whatever reason, it's, you know,
it's unused space out in the ocean, and it gets reliable
wind just as much as you do on land. So it's no eyesore if
you're in the middle of nowhere, of course, you've got the
corrosion problem you got to deal with. But bottom line is
it's free real estate or cheap real estate in any case. So
they've developed 508 megawatts of offshore capacity. So that's
about half a gigawatt, which is not compared to the others, it
doesn't sound like too much, but it's an area that they're
continuing to expand. And they simply have cabling bringing
that power onshore and then it's distributed and connected into the grid.
So one of the things that there's a slide deck as well as
an actual paper, and again, strongly encourage you to read through
in this quite a lot of technical content, but there's also a lot of charts as well that show you
the progression of the increase in renewable energy that Germany's been going
through over the last 10 years at least.
And some of the records being set are quite impressive.
So in 2012, they produced 23.1 terawatt hours of exported power.
So that was the new record for them.
And each year upon year, they're exporting more and more electricity.
So I want to say exporting as a country, you know, they're generating a surplus of energy.
They're generating so much energy that they are basically exporting it out to nearby countries that are connected to these power grids are connected to Germany's grid.
So as you export that energy, you can charge more for it.
And so other countries that can't afford to put in all that infrastructure or don't want to put in that
infrastructure for whatever reason can buy that electricity from Germany.
And so obviously that earns the country money, return on their investment.
So in any case, what they also talk about is something that we talked about in episode two in the main show, and that was using
hydropower pumped storage for storage for after hours.
Now, within Germany, they have currently got about 6.8 gigawatts of
pumped storage capacity.
Now, there's an additional 5 gigawatts that's either planned or currently under
construction at the time of writing of that report.
So that will give them some total within a few years of about nearly 12
gigawatts of pumped hydro capacity such that
they will be able to, during the daytime when there is a massive surplus with solar,
they can simply pump that into the hydro stored system and then of course turn it around
and use it as a standard hydro plant of an evening when the sun is down. Wind of course generates 24
hours a day subject to wind conditions so it's more for buffering that 30, excuse me, 35 gigawatts of
35.6 gigawatts of solar. However, the interesting part is that they are also in one of the documents,
they're also looking at trade agreements with nearby countries to access their pumped hydra
storage. And again, there's a bunch of countries listed there that are ideally situated for such
storage simply because they are, you know, high mountains, they've got water sources,
and so on and so forth. So, they are more ideally suited. It's a geographical problem because
although there are this plenty of capacity in Germany, the problem is that they want more
capacity outside of Germany and then what they can do then is they can do a bilateral energy trade.
So, they can export during the day and then there will be a cost for them to store their hydro
power in another country, say, Scandinavia or whatever, and then they can get the power back
in from them over nighttime.
Or they could do local, like an energy trade.
So you would trade X number of terawatt hours
during daylight hours into the hydro system.
And then the other country
could simply consume that power directly.
And it would work just as well.
So there's many ways to do it,
but they're planning on building more interconnectors
to connect all of the grids together
and increase the capacity between their different grids
so that they can actually implement that whole concept.
So, they've got strategies in place to reduce something that we covered.
We talked about nuclear fission and how dirty nuclear fission is and how dangerous it is.
And essentially, they've said that they're intending to shut down their last nuclear
plant by 2022.
So, that's less than 10 years away.
That's only just over eight years thereabouts away.
And it's, yeah, that's not going to be long at all.
The number had varied from time to time,
but with the amount of capacity that they've installed,
according to these documents anyway,
and the research that I've done now as a result,
I think that's amazing, I think that's wonderful.
However, in the end, they need the interconnectors
and they need to hydro pump storage
to be able to turn that power off completely.
They're still burning black and brown coal for shortfalls.
Yeah, obviously that will change in future
as they install more renewable.
So basically, yeah, way of the future.
I mean, Europe, clearly that Germany in particular are leading the way in exactly the same,
exactly the way that I'd suggested.
And I wasn't aware of that at the time.
So thank you so much to Lenny, Robert, for bringing that to my attention and for providing those links.
They're very informative, very, very useful.
And I just wanted to share that with everybody.
So thanks again.
