I disagree with the metrics here. In the US Hydro power is not considered renewable yet it powers roughly a third of Canadians. Quebec's Hydro Power also powers a large part of New York, Vermont and Massachusetts.

I think they're focused on newly-built renewables rather than hydroelectric which was built decades ago by massive government subsidy and seems unlikely to see real expansion given environmental concerns re: fish spawning, etc.

In British Columbia over 50 new hydro electric plants have been built in the last 30 years by private industry. People may say they are subsidized since they often get $100/MWH for the first 30 years of operation but that is the price that must be offered to mobilize investment and it isn't much higher than the projected construction cost from the site C dam which would have much better economies of scale and the Construction cost doesn't include the 30 years of studies and consultation BC hydro did whereas that is covered by the 100$/MWH for the private hydro plants.

Here is a list of Independent power producers in BC https://www.bchydro.com/content/dam/BCHydro/customer-portal/...

I don't know if it'll be as big as you think. It takes a fair amount of power to actually refine gasoline.

I'd love it if you could point me to a source quantifying how much electrical energy from the grid refineries use. Refineries expend a lot of energy turning crude into motor fuel but AFAICT most of that is made by consuming some of the input crude itself (for hydrogen and process heat). None of the citations I've found so far for high refinery energy use quantify the electrical demand they pull from the grid. So whil…

There's some numbers here:

https://www.eia.gov/dnav/pet/pet_pnp_capfuel_dcu_nus_a.htm

and here:

https://www.eia.gov/dnav/pet/pet_pnp_refp2_dc_nus_mbbl_a.htm

Which suggest 46,860 million kilowatt hours of grid electricity used.

577,245 thousand barrels of motor gasoline produced.

Which works out to 2kWh per gallon (but ignores the fact that lots of other non-gasoline products are produced as part of the same process).

I've seen estimates where if it was 4kW per gallon, then EVs are kind of breaking even and there would be no increase in electricity usage. I'd wildly estimate that maybe only .2 kWh would actually be saved since kerosene etc. would still need to be refined.

It's actually possible, that if a carbon tax was imposed, then refineries would use more grid electricity sourced from wind/solar/nuclear/hydro as a cost saving measure rather than burn fossil fuels.

Could you explain why you think that's a misrepresentation? Why do you think "essentially free" marginal renewable cost is a falsehood? The difference between lettings the electrons flow and not letting the electrons flow on an installed plant is what, exactly? That's what's being referenced. Though there's lots of data to support the article, they do leave out the cost of extracting natural gas from the "practically…

Why do you think "essentially free" marginal renewable cost is a falsehood? Unless you can control the sun, the cost for one extra kilowatt of solar power is the cost of a 1kw solar panel?

I'm pretty sure my implication of "acceptably safe" was fairly clear.

So... another straw man.

"industry demands greater direct subsidies" Can you provide some examples of grid-scale solar or wind projects that don't get massive government subsidies?

Apparently the answer is no.

A new generation of students who grow up doing math in VR will solve the plasma containment geometry problem, which is one of the major fusion hurdles.

Just like a new generation of engineers doing math on computers would give us flying cars?

No, we don't need flying cars so that won't happen.

You are somewhat misrepresenting the energy situation in Germany.

>...Coal is still the largest source of power in Germany. ...In 2007 German Chancellor Angela Merkel and her party agreed to legislation to phase out Germany's hard coal mining sector. That does not mean that they support phasing out coal in general. There were plans to build about 25 new plants in the coming years. ... No concrete plan is in place to reduce coal-fired electricity generation. As of October 2015, the remaining coal plants still under planning include: Niederaussem, Profen, and Stade. The coal plants currently under construction include: Mannheim, Hamm D, Datteln, and Willhelmshaven. Between 2012 and 2015, six new plants went online. All of these plants are 600–1800 MWe ...A coal phase-out for Germany is implied in Germany's Climate Action Plan 2050, environment minister Barbara Hendricks said in an interview on 21 November 2016.

https://en.wikipedia.org/wiki/Fossil_fuel_phase-out

To eliminate a non CO2 producing energy source and continue to use the most dangerous source of power which is also the major producer of CO2 for a couple more decades (best case), is pretty irresponsible.

Fukishima was a major accident and resulted in zero deaths to the public. You wrote: "I don't see the problem being that nuclear can't be made safe." and also seemed to approve of an entire county abandoning nuclear power when they are using power sources orders of magnitude more dangerous. It did sound like you meant that any accident from nuclear power would be unacceptable to you since the alternatives Germany will be using for decades are more dangerous to the human health and the environment. You now say that you meant "acceptable risk" - unfortunately that is a somewhat meaningless subjective term. You can only compare a choice against its alternatives and since we know we need to generate terawatts of power for our civilization to function, the real question is what is the relative risk from generating power from different sources. From a previous comment someone made, here are the death totals for generating power:

Energy Source Mortality Rate (deaths/trillionkWhr)

Coal – U.S. 10,000 (32% U.S. electricity)

Natural Gas 4,000 (22% global electricity)

Solar (rooftop) 440 (Wind 150 (2% global electricity)

Nuclear – U.S. 0.1 (19% U.S. electricity)

If you demand zero risk when producing terrawatts of power, you aren't going to find it. In the same way that if you were afraid of jet travel, all anyone can say to you is that jet travel is safer than driving, not that there will be no plane crashes.

"didn't mention coal in your original statement."

Correct. You brought it up along with the presumption that I'm in favor of it.

>You are somewhat misrepresenting the energy situation in Germany.

Actually I think you are:

"The coal plants currently under construction include: Mannheim, Hamm D, Datteln, and Willhelmshaven. Between 2012 and 2015, six new plants went online."

Plants take a long while to go from planning to complete. These plants were ALL planned and approved before Merkel made her decision. No new coal plant has received a permit since 2009, 2 years prior to Fukushima, meanwhile many others are slated for early closure.

Coal is most assuredly on the way out in Germany, NOT, as you seem to presume, making up for all of the lost nuclear power.

>Fukishima was a major accident and resulted in zero deaths to the public. You wrote: "I don't see the problem being that nuclear can't be made safe." and also seemed to approve of an entire county abandoning nuclear power when they are using power sources orders of magnitude more dangerous.

I approve of them abandoning both, which they are doing. It wasn't ever going to happen overnight and it is ridiculously unrealistic for you to expect that it will.

>You now say that you meant "acceptable risk" - unfortunately that is a somewhat meaningless subjective term. You can only compare a choice against its alternatives and since we know we need to generate terawatts of power for our civilization to function, the real question is what is the relative risk from generating power from different sources.

Do you have a problem with the risks presented by wind and solar which are both replacing the power from the nuclear and coal plants which are slowly going offline in Germany?

Do you have a problem with this trend continuing? I don't.

>Fukishima was a major accident and resulted in zero deaths to the public.

573 deaths are attributed to it, and it's projected that between 130 and 1100 deaths from cancer will be attributable to it.

>If you demand zero risk when producing terrawatts of power, you aren't going to find it.

I'm okay with the risks presented by the solar and wind. Most importantly there are no large scale tail risks for solar and wind, unlike nuclear. Falling off a roof is typically easier to mitigate than cancers following nuclear disasters, too.

No, what I said was "Are you trying to argue that keeping coal plants and shutting down nuclear plants is a good idea?"

>>>You are somewhat misrepresenting the energy situation in Germany.

>Actually I think you are:

No, what I wrote was from the wikipedia page. If you think you are right and they are wrong, you are free to edit the page with more accurate info.

>..."The coal plants currently under construction include: Mannheim, Hamm D, Datteln, and Willhelmshaven. Between 2012 and 2015, six new plants went online." Plants take a long while to go from planning to complete. These plants were ALL planned and approved before Merkel made her decision.

It would obviously have been easier, less disruptive and cheaper to cancel plants that are still in construction and not actually generating power. Much more costly and dangerous to the world to shut down nuclear power plants to build more coal plants.

>...Coal is most assuredly on the way out in Germany, NOT, as you seem to presume, making up for all of the lost nuclear power.

No, I did not say that nor did I imply that. What I said was: "To eliminate a non CO2 producing energy source and continue to use the most dangerous source of power which is also the major producer of CO2 for a couple more decades (best case), is pretty irresponsible." They are using less coal and have finally stopped subsidizing the coal mining industry this year - these are all good things. If they had kept their nuclear power plants, they could have eliminated that many gigawatts of coal burning right away. I don't think what I said was difficult to understand. And as I think you agree, coal is far more deadly than nuclear power.

>...Do you have a problem with the risks presented by wind and solar which are both replacing the power from the nuclear and coal plants which are slowly going offline in Germany?

Replacing coal with any other power source is an improvement - I think everybody (well except those who own a coal mine) agree with that. Roof top solar and wind have been more dangerous than nuclear, but these 2 power sources don't place massive negative externalities on the rest of the world like coal does, so they are preferred over coal.

>...573 deaths are attributed to it, and it's projected that between 130 and 1100 deaths from cancer will be attributable to it.

It is misleading to not put the 573 number in context. These weren't people who were killed by an explosion or radiation poisoning, etc, but instead were labelled as "disaster-related" in the areas near the nuclear power plant. This is when a local death was considered to not be directly caused by a tragedy but by a "fatigue or the aggravation of a chronic disease due to the disaster". With the earthquake causing more than 18 thousand dead or missing and 6 thousand injured, extensive structural damage, including fires in many areas, etc. It isn't clear how well one can separate out the stress of moving people out of the area with the stress caused by a massive earthquake and its 11 thousand aftershocks. Other reports don't reference that claim.

Both the WHO and UNSCLEAR reports predicted any deaths from radiation would be low enough to not be detectable in the statistics - and they based this on using the linear no-threshold model. I think your 130-1100 deaths estimate was from a report done by Stanford and in that report, the range was 15-1100, not 130-1100. (It isn't clear to me how the Stanford report got its numbers.)

>...I'm okay with the risks presented by the solar and wind.I think of any death as being a tragedy, whether it makes the news or not.
