If Germany adopted the Chinese model, then coal consumption would double or triple.

Re: Natural Gas isn't helping

Telegraph-
I also recognize that the published "proved reserves" for most any mineral or fuel are almost certainly too low for what is really in the ground. The new fracking techniques are getting oil and gas out of rocks that were [more]

Re: Natural Gas isn't helping

China's addition of new energy sources is barely keeping up with growth...and not replacing anything. They are still building 20-30 new coal plants a year. They will burn coal for at least 30 years each until most of the easy to get to coal in the [more]

Re: Natural Gas isn't helping

We've had people claim (and show calculations) that there isn't enough lithium to make all the batteries for all the vehicles in the world to be hybrids, much less full EVs. I have no idea if this is really true or [more]

How did Sweden sell it?

Sweden's electricity supply was already very low carbon even before the AGW issue came up.

Re: Natural Gas isn't helping

On the subject of fugitive methane emissions, a study came out earlier this year that I don't remember seeing. Instead of looking at the sources of methane leaks, they looked at the overall concentration in the atmosphere. They estimate a leakage [more]

Re: Natural Gas isn't helping

In the Nature link, they have some references to the IPCC. I believe the IPCC still uses the 100-year global warming potential (GWP) for methane. If they used something more reasonable, such as the 20 year GWP, then the fugitive leakage impact is [more]

Poland will veto 40% CO2 reduction – Piechocinski

As of 2012, Poland's electric power generation was 84% coal-fired.
6.2% came from biofuels, and everything else is fairly small (less than 5% each)

Re: CO2 Increase is not Nemesis

If what Bill Gray says is true about the specific humidity of the upper troposphere, it should be easy to confirm with actual measurements over time. Indeed, IPCC4 has a chart showing upper troposphere moisture increasing over time, which contradicts [more]

So we were using MOX 40 years ago and now we can't figure out how to do it?

Re: Global Warming Statistical Meltdown

The global consensus on AGW continues to broaden.

And the inability of governments to come up with an effective plan to actually do something about it continues unabated.

Re: Keeping the Lights On

Nuclear reactors are designed to shut down automatically if the main coolant pumps fail. The Thresher's power plant was an S5W PWR. PWRs need coolant flow to adequately remove the heat from the core. If the flow is lost, the reactor shuts down. It [more]

Re: How would you invest energy research $$?

Rather than just saying "renewables", I would be interested to know what sort of specific technologies you think should be explored. What is needed, in my view, is a renewable energy technology that can provide power on a 24/7 basis. The [more]
