CURRENT

Follow up (Part C) to The Battery Problem with a discussion of Germany’s forward-thinking approach to renewable energy.

This is pragmatic follow-up receiver episode to the boundary problem and then Alexandra Michael hostage IgG baseband arm wanted to talk specifically about some feedback from Marge Allen by the name of our Lenny P Robert and on twitter he sent through some very interesting links to situation in Germany in Europe with respect to the ER renewable energy situation over another in that country and in parts of Europe as well now the least of these are in the our show notes for this follow-up statement and is what's interesting is that Jim offer for those who don't know Germany actually led the way a lot of respect with regards to renewable energy and the renewable energy sources act came into force in 2000 and there was it was written a few years before they became a force in 2000 and asked a whole bunch of things a guaranteed feed in tariffs one of the problems that we had here in Queensland was that the government sent in the feed in tariffs that are very attractive rate and then after the uptake of the initial uptake after a few years they realise they are unsustainable anime backup is less that if anyone is on the existing tariffs will give them forward to for a bit longer boats there they could end them at any point that they choose any new people signing up were down to our eight cents we got eye I'm I signed up on eight cents a kilowatt hour are feed in whereas originally it was I think 40 or so something ridiculously high and is anyhow so a lot of people put in small systems and were able to get away with offsetting their energy costs form a lot of money are worries my casement when a 5 kW system hour which is the largest allowable in order to get those sorts of fun trade-offs but in any case either way either we will look at it in the Germany Dave Bay figure this out and implemented an act into into law a long time ago so over and getting close to 14 years ago now so what's that has driven has been a massive explosion of of development in solar and in wins and the solar power capacity for example are the current store by serves of the year 2013 is 35.6 MW of solar generating capacity and in addition wind power is 32 GW of capacity as onshore and in addition out there developing offshore are wins generation one of the ideas of doing offshore is that you can have a pylon out out to see where there's is not excited too shallow to be a shipping channel or for whatever reason its CEO it's our only used space out of the ocean and it gets reliable wind just as much as you do on land so it's no eyesore if your animal nowhere because you got the corrosion from your deal with but bottom line is it's free real estate or cheap real estate in any case so they develops our 508 MW of offshore capacities as behalf about half a gigawatt which is not competitor the others doesn't sound like too much but it's an area that they're continuing to expand and they simply have bar cabling Reno power onshore and is distributed and collected into the grid so what are things that these there is a slide deck as well as a action actual paper and start again strongly encourage you to read through this quite a lot of technical content are but there's also a lot of chances while the show you the progression of the increase in renewable energy journeys to going through over the last 10 years of least and some records being set a quite impressive start to thousand 12 they produced 23.1 TW hours of exported power to that was a new record for them and each year upon year they're exporting more and more electricity is also exporting as a country you are degenerating a surplus of energy that that the generating so much energy that they are basically exporting it out to nearby countries that are connected parts of his boundaries against the Germany spread size you export that out that energy you can charge more for and some other countries that can't afford to put in all that infrastructure or don't want to put in an infrastructure for whatever reason can buy that electricity from Germany as we set out as the current the country money our return on their investment so in any case what they'd also talk about art is something that we talked about are in episode two in the main and the main show and that was using hydropower pumped storage for storage are for after hours now within within Germany they have currently lost about 6.8 GW of pumped storage capacity that is the additional 5 GW is either plans or currently under construction at the time of writing about report so that will give them a sum total within a few years of about nearly 12 GW of pumped hydro capacity such that they will be able to during the daytime and there is a massive surplus with solar they can simply store pump pump that into hydro stored system and that it was turnaround and use it as a stand hydro plants of an evening when the sun is downwind of course generates 24 hours a day subject when conditions so small for buffering at 3035 GW of far the 5.6 GW of solar however the interesting part is that they are also in one of the documents there are also looking at trade agreements with Neary nearby countries to access their pumped hydro storage and again there's a bunch of countries listed there that are ideally situated for such storage simply because they are high mountains they got water sources and so on and so forth so they are more ideally suited its geographical problem because although there are lists capacity in Germany the problem is that they want more capacity outside of Germany and I can do that as I can do a bilateral energy trade so they can export during the day and then there will be a cost for them to use all their hydro power in another country is a Scandinavian whatever and then they can get the number power back in from them are of a night-time oily could do local sleeves are daikon energy trade so you would trade X number of our terawatt hours during daylight hours into the hydro system and any other country could simply consume that power directly and CO it would work just as well so there's many ways to do it but they're planning on building more interconnected is to connect all the grids together and increase the capacity between their different grids so that they can actually implements are that whole concept so they got strategies in place to reduce our something a week which will become we talk about nuclear fission and how old dirty nuclear fission is and how dangerous it is an essentially Dave said that they are intending to shut down our last nuclear plant by 2022/less than 10 years away that's only just over eight years of thereabouts away and it's you that's not gonna be long at all and is 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.e. are a thing as amazingly as wonderful however in the end they need interconnected only the hydro pumped storage D about so that power offer completely still burning black and brown colds of the shortfalls you obviously that will change in future as a storm or renewable so basically airway the future I'm in Europe were clearly the Germany particularly in the way in exactly the same these are in a way that I'd I'd suggested and I was aware about the times I thank you so much to our Lenny our Robert for bringing that to my attention and provide those links are very informative very a very useful eyes want to share that with everybody so our thanks again´┐Ż
