Why Germany’s Plan To Build Electric Cars Will INCREASE CO2 Emissions

via Climate Change Dispatchhttp://climatechangedispatch.com

Germany’s plans to transition the country to electric cars will probably increase carbon dioxide (CO2) emissions, according to an engineer. The basic problem is that Germany isn’t close to generating nearly enough energy from wind and solar to power electric cars, and the country has been forced to slow its green energy plans due to […]

Fake Polar Bear Scare Unmasked: The Saga of a Toppled Global Warming Icon

via Watts Up With That?http://ift.tt/1Viafi3

In spite of claims that polar bear populations are facing pressure from loss of Arctic summer sea ice, their numbers have in fact grown. Video follows. Guest essay by Dr. Susan Crockford For more than ten years, we’ve endured the shrill media headlines, the hyperbole from conservation organizations, and the simplistic platitudes from scientists as […]

Does Solar PV in half of Europe make more energy than it consumes?

via JoNovahttp://joannenova.com.au

You might think we’d know whether a solar PV system produced energy before we installed 1,000 Megawatts of it. But it’s hard to even know after the fact. Dr John Constable points us at an interesting new paper that discusses the odd creature called EROEI. This stands for energy return on energy invested. If you get back less than “one”, it sucks.

That sounds like a fine idea except everyone seems to get different answers to the same question. Solar PV in Switzerland achieves either a tenfold return or it costs a fifth of your energy. Plan your national policy with a Ouija Board?

Constable comes to the conclusion that the whole calculation is so uncertain it’s useless. There are so many subjective estimates on the “energy invested side” that the answer is almost irrelevant. Constable points out that what we really need to know is how the whole system responds to the addition of a new generator –but the whole grid analysis is even harder than just the EROEI to calculate.

His conclusion, it that we really need something more like a neural net to calculate the costs. Luckily we have one — us — and the contractual free […]

Polar Bear Scare Unmasked: The Saga of a Toppled Global Warming Icon

via polarbearsciencehttps://polarbearscience.com

For more than ten years, we’ve endured the shrill media headlines, the hyperbole from conservation organizations, and the simplistic platitudes from scientists as summer sea ice declined dramatically while polar bear numbers rose.

Now, just in time for International Polar Bear Day, there’s a video that deconstructs the scare. It runs about 8 minutes, written and narrated by me, produced by the Global Warming Policy Foundation.
