Comment Re:Renewables will never work (Score 1) 294

Its all right here for anyone to see. Germany has practiced priority dispatch of wind and solar for quite some time. This means you must first purchase any available wind and solar before you can use other sources.

China does it aggressively as well;

California practices it as well, as do other states;

The accomplishment is that renewables produce about 60% as much electrical energy as coal. Most of that from hydro and biomass. A bit from wind, almost negligible from solar.

Is still laugh when folks talk about solar and wind as the solution, but take credit for hydro and biomass when cheering progress.

Who said it was impossible for renewables to generate 40% less electricity than coal when you include hydro and biomass (actual generation in GWH, not 'capacity' which is meaningless). Call me when wind gets to 10% of coal generation, and solar gets to 4%. Those are the two everyone says will solve our problems.

Comment Re:Subsidies (Score 2) 294

Most of this renewable power this article is cheering about is hydro and biomass. Wind and solar, the two sources that everyone wants to claim will solve all our problems, are only actually generating a very small percentage of global electricity, and that's mostly wind. Solar barely registers on the scale of GWH generation globally.

Windmills are there to cover peaks.

No, this is nonsense. Windmills are there to produce power when the wind is blowing. Wind is not "peaking power", that can fill in the gaps from other sources, because it is not dependable. The opposite is true: variable winds create peaks and troughs that need to be filled by on-demand sources such as gas turbines or ... hydro.

DBill spreads that nonsense all the time, yet in most place the grid is required to accept all wind generation and run back other sources. Like you said, its intermittent, so you can't use it for peaking because its not necessarily available during the peaks. Wind charts for Germany show no correlation at all between wind output and usage peaks. Its the same everywhere. Wind is only curtailed in very rare circumstances.

He hates when people use the well established industry measure of Capacity Factor because it shows the weakness of solar and wind. He hates it so much he fabricates usage scenarios that don't exist.

Are you really incapable of understanding that the OP was talking about building more nuclear plants, not just depending on the existing fleet?

And so, if you are old enough, please tell us exactly who made that promise? I bet you don't even know where it came from. I bet you also don't even know what the cost per MWH of existing nuclear is compared to other viable alternatives.

Comment Re:Nuclear too expensive and too slow (Score 0) 367

But we don't have to rely on nuclear, we can just stop burning fossil fuels, and stop using so much energy overall. It would require an immense social adjustment to achieve this, but it has no roadblocks other than making people care enough to do it.

Continue to dream on.

People will stop using fossil fuels when something else is cheaper without subsidizes.

And since that is unlikely to happen, it would probably take military force to get some countries to switch.

Bringing a new nuclear plant online safely takes decades,

You begin with a false statement, then proceed to spout ignorance and pie in the sky idealistic yet unrealistic things like 'just stop burning fossil fuels'.

Submission + - Votes Switched From Trump to Hillary in Texas ( 2

Okian Warrior writes: Early voting for the 2016 presidential election started yesterday for people in some areas who have been given the opportunity to avoid the long lines on November 8.

However, in Amarillo, a woman was shocked to see her ballot flip from Republican to Democrat.

“Gary and I went to early vote today,” wrote Lisa Houlette on Facebook. “I voted a straight Republican ticket and as I scrolled to submit my ballot I noticed that the Republican straight ticket was highlighted, however, the Clinton/Kaine box was also highlighted!”

“I tried to go back and change and could not get it to work. I asked for help from one of the workers and she couldn’t get it to go back either. It took a second election person to get the machine to where I could correct the vote to a straight ticket,” she added.

I don't recall anyone here every saying batteries haven't advanced. They certainly have. More so in manufacturing tech than actual battery chemistry tech, but they go hand in hand. They key advancement has been bringing the price down on lithium ion batteries through advanced production methods that allow higher density. This the result of half a century of intense effort to keep improving them. There are limits to lithium ion though, its been around a long time and there hasn't been another technology yet to supplant it.
