Germany still has many coal and gas plants in use. And especially our gas plants are currently those who are used when the renewables are fluctuating. You can bring a Gas and Steam Plant from zero to 100 in 20 minutes. And it's normal to use those fast reacting plants to stabilize the grid. That's a normal procedure in every bigger grid.
You are confusing additional stabilizing power in case of failture with unpredictable solar spikes that needs to be accounted for. Until you get better batteries there is nothing you can do to make solar effective.
Take a look for this example:
As whole solar does provide a lot of energy as someone chart pointed out. Problem is that energy is delivered when it is needed THE LEAST and they can't even spend solar power so they have to export it.
And that is currently with such amount of solar panels. If you increase them by 50% or more you are talking about shutting down completely most of powerplants so taht few hours a day solar can power whole thing. AND not exactly like that because solar panels are not concetrated so you either way will need to rebalance network which is HARD on daily basis.
- Ans those 27 Tons are packaged in much more Weight and volume. Let me guess you heard this number once and thought, hey that's not that much, right?
PER 1000MW PER YEAR. Germany whole economy per 2013 used 40k MW per day. Which means for whole year of whole Geramany economy reactors would produce around 1080 tones of waste for 100 years (assuming energy consumption won't increase) : 108000tones which is NOTHING. One good big coal mine could completely store whole thing for next few thousands year. And it that 100 years we will have fussion which produces even less and very low radioactive material.
- Good idea just load those radioactive waste in some regular coal mine perfect. But wait why is there still no final Nuclear repository? If it's so easy why is nobody taking our thousand of tons of nuclear waste we still have in our small country?
Because business is very loosely regulated and various companies are storing that material. AND YES old mines are used most of the time.
- Then show us please how many of those modern reactors are out there and how expensive they are to plan to build and maintain without government subsidies.
- Yeah, areas that are radiated for very very long time are grossly overestimated. Let's just ignore those 400 (and that number is from what source please?)
“There is no scientific evidence of increases in overall cancer incidence or mortality rates or in rates of non-malignant disorders that could be related to radiation exposure. The incidence of leukaemia in the general population, one of the main concerns owing to the shorter time expected between exposure and its occurrence compared with solid cancers, does not appear to be elevated. Although most highly exposed individuals are at an increased risk of radiation-associated effects, the great majority of the population is not likely to experience serious health consequences as a result of radiation from the Chernobyl accident. Many other health problems have been noted in the populations that are not related to radiation exposure.”
2008 Raport directly says that if you were not directly exposed to radiation AT THE SITE ITSELF there is no any evidence you would get even increased cancer.
There were extensive studies done on animals who live there since then and those studies did not found any trace of anomaly (like cancer above predicted outcome). Since that tragedy populations of boars and other animals exploded there and those animals were not any different from normal animals.
Simply put our predictions about exposure and effects of radiation do not reflect reality.
- That's the only point I'm with you. Coal plants are bad. very bad. But "just" switching to Fission until Fusion is here is not possible. Fusion is not there to save us in the next future. ITER is not active and DEMO far far away. Wendelstein 7X is awesome and maybe much more interesting then ITER. But still just a small experiment.
And why is that ?
Here is france, they make 90% of their energy from Fission and they produce much less carbon than Germany AND French energy is MUCH cheaper.
Prices of energy before Germany switched off their nuclear reactors after Fukushima:
- Solar and wind are not just wasted money and they work fine for proper mass scale use. There are enough showcases to look up. Denmark, Germany, Marocco. You cant just ognore that.
No they don't. As i said before. They work fine because there are normal powerplants which keep grid alive and provide stable power to grid for whole day.
UNLESS you get proper batteries solar powered cities is just garbage myth. And there is nothing on horizon that can fix that easily.
