86 Percent of New Power in Europe From Renewable Sources in 2016 (theguardian.com)

Renewable energy sources made up nearly nine-tenths of new power added to Europe's electricity grids last year, in a sign of the continent's rapid shift away from fossil fuels. From a report on The Guardian: But industry leaders said they were worried about the lack of political support beyond 2020, when binding EU renewable energy targets end. Of the 24.5GW of new capacity built across the EU in 2016, 21.1GW -- or 86% -- was from wind, solar, biomass and hydro, eclipsing the previous high-water mark of 79% in 2014. For the first time windfarms accounted for more than half of the capacity installed, the data from trade body WindEurope showed. Wind power overtook coal to become the EU's second largest form of power capacity after gas, though due to the technology's intermittent nature, coal still meets more of the blocâ(TM)s electricity demand.

      I am often struck by the way that the current debate about intermittent renewable power is strikingly similar to the arguments between net heads and bell heads two decades previously. The funny part from a historical standpoint is that both were kind of right.

      You also miss an important point. The other factor that is important in power generation is if it is dispatchable. By dispatchable I mean can she adjust the power generated quickly to meet demand. Current nuclear and coal plants require long startup times and current nuclear plants can't throttle their power output very well, which makes them much less valuable in a world with a lot of renewables. Combined-cycle natural gas, on the other hand, is easy and quick to start up so it is very dispatchable.

      There are a few other factors that somewhat mitigate the intermittent nature of solar and wind. The first one, kind of obvious, is that you know more or less in the near future how much power you will be able to produce from these sources (we know when the sun rises and sets, and weather forecasts 24 hours out are fairly accurate -- especially if you just want to know if it will be sunny or windy). The other is that if we have a larger geographical distribution for solar and wind, the intermittency problem is somewhat mitigated -- it is unlikely to be cloudy and windless everywhere at the same time. Finally, there are other ways to store energy than batteries. If you have an old-style hot water heater rather than an on-demand system, you are essentially storing energy in the hot water tank -- and it would be plausible to have a system that would heat your hot water when the sun is shining or the wind is blowing. You can do similar things with heating and air conditioning systems in buildings, and even to a lesser extent in refrigerators or freezers.

      You will still need some storage, but probably not as much as you think.

      It's also not true that there's no way to store electricity. You should know better than that, you've never heard of batteries? What you probably mean to say is that electrical storage is too expensive to be economically viable. That statement, however, is disputable. Definitely in places where hydropower is stored in reservoirs this is untrue, and new battery, fuel cell, compressed-air, and even flywheel technologies are coming online with decreases in price.

      Again, you are sort of right, but practically wrong. Energy storage is indeed expensive if for no other reason than conversion losses. A really good chemical battery is going to chew up about 30% of the input AC power when you do all the conversions and account for all the losses (AC -> DC, DC into chemicals to charge the battery.. Chemicals -> DC, DC to AC to discharge it). The equipment just doesn't scale well either and over the total cost of such systems + the loss make them *really* expensive.

      Then there is the question of "how big" you need to make the storage capacity. I dare say that it's got to be a LOT bigger than you think it should be t account for the worst case. This is driven by or dependence on the electric grid and it's reliability. We simply cannot easily absorb outages and not realize that they will come with significant financial costs and even loss of life. We have nearly zero tolerance for blackouts, which drives the needed capacity in any storage system higher and higher. Oh, and don't forget the extra capacity on the generation side to recharge your storage PLUS keep the grid online...

      The primary point I'm making here is that storage is NOT a viable option. Renewables as they exist today, do not have enough reliability to be anything more than alternatives and we will need to keep backup fossil fueled alternative sources ready for when the wind stops and it's raining for days longer than the batteries can cover....

      Storage doesn't solve the problem because it's too inefficient As I pointed out: storage is efficient to roughly 90% ... your other claims regarding it are wrong. A simple coal plant has an efficiency of 42%, same as a nuclear plant. A high tech gas plant is approaching 60% by combining a gas turbine with a traditional steam boiler/turbine. So: storage is far far far more efficient than a power plant.

      Shesh, yet again another crazy comparison....

      Why don't you compare the efficiency of my lawn mower to the capacity of my lungs to oxygenate my blood? Or the efficiency of a Saturn V in carrying cargo to your electric train?

      My point, which you totally miss, it that even at 90% efficiency (which I don't think is possible and you provide no evidence that it is) storage doesn't really help enough to make renewables our ONLY source of power. You cannot store enough power, renewables can have ZERO output for days... Plus, if you did have enough storage to cover you for days, you will have to build out enough additional capacity to charge that storage, PLUS carry any load that happens to be drawn. I can see an argument for storage capacity in excess of 2 peak days supply, with generating capacity nearly 150% of the average (which will get you a 4 day recharge cycle to get a 2 day reserve) or even 200% of the average (for a 2 day charge cycle for a 2 day reserve).

      And your "buy power on the spot market when you run short" comment is laughable in this context. Where do you think the power you buy comes from?

      I'll bet you that there are a pile of fossil fueled plants that come on line to sell some expensive power at peak prices so they can make some big Euros.

      Which proves my point.... Fossil fuels cannot be done away with anytime soon and we are foolish to think that building renewable sources will allow that. It cannot. It can allow us to not use Fossil fuels as much, but you still need the capacity as a backup, or some calm cloudy day will bring your electric grid down and you will suffer an economic disaster..
