Re: Arctic sea ice -- DrBob mistake?

Can anyone actually tell if the accuracy of temperature reconstructions has gotten better in the last ten years?

If you look at it probabilistically, yes, they've gotten better. In that time scientists have incorporated multitudes of [more]

Re: India: 'real electricity'

100 kW for 2400 people is 41 watts per person. Since the sun only shines half of the day (at best), the average is going to be less than that. 41 watts is better than nothing, but the villagers obviously understand something more is needed if they [more]

Re: EPA to Shut Down Nuclear?

This looks like a real flaw to me. I submitted a comment to the EPA, copied below, and I encourage others to do the same. You are welcome to crib from my comment if you like.

The People's Climate March: Hansen

Hansen's latest essay encourages people to join the People's Climate March in NYC Sept. 21, to put pressure on politicians to act on climate. He lays out again why he believes that a carbon tax is the only globally effective way to reign in carbon [more]

Re: Alternative to EVs and FCVs

EVs have some advantages, but it is no slam-dunk that they will be the dominant transportation format.

I think transport will go electric ... but agree that it's no slam dunk that pure battery electric will dominate. Hybrids that [more]

Re: Hawaii: 65% Renewables by 2030

Pete opines: The chance of this plan lowering electric bills, as stated, is zero.

I dunno. Their rates currently are the highest in the nation at $.35/kwh. I'm pretty sure that even distributed residential PV comes in cheaper than [more]

Re: Alternative to EVs and FCVs

It's not futuristic in that Audi has an industrial scale production plant in operation. And it seems pretty cost effective.

Notice that Audi does not mention prices, that's usually a pretty good sign that it doesn't compete with [more]

Re: The era of Big Solar has arrived

It cost about $2 billion to build Ivanpah. It costs about $10 billion to build a nuclear power plant.

The $8 or 9 billion nuclear plant would have a max capacity about 3 times that of Ivanpah at 1117 megawatts for an AP1000 vs 377 [more]

The technical breakthrough is about being able to extract the CO2 [from the atmosphere] to a nearly pure form

The cost is the other thing being buried. The cost of reducing emissions is probably at least an order of magnitude less [more]

Re: Alternative to EVs and FCVs

Seems only cost prohibitive relative to burning fossil fuels. May not be relative to the cost of having to create a new energy distribution infrastructure as required for EVs and FCVs.

EVs look to have a pathway to cost of ownership [more]

Re: Alternative to EVs and FCVs

I applaud their research and hope it will one day be practical but methinks that one day is quite a long way in the future.

Maybe one day, decades down the road, synthetic gasoline will help fuel a plug-in hybrid but it will undoubtably be [more]

Wind far Outpaces Nuclear in China

Even in pro-nuclear countries like China and India, utility scale wind is proving far easier to deploy than nuclear. Maybe that will change as we gain experience building third-generation plants, but we'll have to see.

Re: Why Energy Storage Will Not Work

Some interesting stuff to think about, but I see some things I disagree with, strongly in some cases.

For instance the authors completely dismiss the utility of demand management as a way to partially match variable energy supply to variable [more]
