GE announces monster 12 megawatt wind turbine – nearly as tall as the Eiffel Tower

Watts Up With That?

From the “bigger they are, the harder they fall” department comes this monster from General Electric:

GE Renewable Energy GE will invest more than USD 400 million over the next three to five years to develop and deploy the largest, most powerful offshore wind turbine – the Haliade-X 12 MW.

Featuring a 12MW direct drive generator and a capacity factor of 63 percent, the Haliade-X will produce 45 percent more energy than any other offshore turbine available today, the company said.

GE Renewable Energy aims to supply its first nacelle for demonstration in 2019 and ship the first Haliade-X units in 2021.

Towering 260 meters (853 feet) over the sea, more than five times the size of the Arc de Triomphe in Paris, France, the Haliade-X 12 MW carries a 220-meter rotor.

Designed and manufactured by LM Wind Power, the 107-meter-long blades will be the longest offshore blades to date…

Looming Catastrophe: Power Grid Collapse Now In Sight in New York

Watts Up With That?

“…many staff people at DPS, DEC, and NYISO who know this is going to end badly.”

Guest essay by John Droz Jr.

Indian Point Nuclear Power Station in New York. It sits on the east bank of the Hudson River, about 36 miles north of Midtown Manhattan, plans to shut down both of its operating reactors by April 2021.

Here is a fascinating and revealing news article behind a paywall that I’m alerting you to. It is about just a few of the complications that will result from New York State’s (NYS) Clean Energy Standard (CES).

It discusses the NYISO (New York State Independent System Operator) 2018 Power Trends Report which (paraphrasing Winston Churchill):

…defends itself against the risk of being read by its very length and obfuscating technical jargon.

Note that the article observations are coming from a top NYISO person. In other words, this is someone on the electrical energy front…

Claim: emergent plate tectonics caused “snowball Earth”

Watts Up With That?

From the “but wait, I thought only CO2 had the power to change the climate” department comes this revelation.

New research suggests that dawn of plate tectonics could have turned Earth into snowball

A research duo from The University of Texas at Austin and UT Dallas have put forward a hypothesis that links the dawn of plate tectonics with “snowball Earth”–a period of climate change that sent the planet into a deep freeze that lasted millions of years.

They expect their hypothesis to generate controversy. Geologists usually place the start of plate tectonics at about 3 billion years ago, while the new hypothesis puts the process in a much younger era known as the Neoproterozoic, which occurred about 542 million to 1 billion years ago.

“If you look at the preserved record, diagnostic evidence for modern plate tectonics involving deep subduction is mainly Neoproterozoic and younger,” said co-author Nathaniel Miller…

The Biggest Deception in the Human Caused Global Warming Deception

Watts Up With That?

Guest Opinion: Dr. Tim Ball

It is likely that every year annual variance in the amount of water vapour in the atmosphere exceeds the warming effects of human CO2. I can’t prove it, but nobody can disprove it with any reasonable measure of evidence because there is insufficient data or understanding of natural processes. However, it is likely true, and alone destroys the human-caused global warming (AGW) narrative. This is one reason why AGW is the biggest, most pervasive, and longest lasting ‘fake news’ story to date. It is also a ‘deep state’ story created and perpetuated by and through the bureaucracies.

Part of the reason the deception persists is because of the failure of skeptics to explain the scientific problems with the AGW claim in a way people can understand. As I have written, most people, that is the 85% who lack science skills, find the science arguments of…

Polynya refresher: open water in spring is due to winds & currents, not ice melt

polarbearscience

Arctic sea ice begins to open up in spring at predictable locations due to currents and prevailing winds and this was as true in the 1970s as it is today. Polynyas and widening shore leads that most often get mistaken for early sea ice melt are those in the Beaufort and Chukchi Seas and in Hudson Bay.

But contrary to concerns expressed about possible negative implications of these early patches of open water, these areas have always been critical congregation areas for Arctic seals and are therefore important feeding areas for polar bears.

Polynyas and shore leads_Smith and Rigby 1981

From one of my posts three years ago on the topic (20 May 2015):

“The map of sea ice extent in Canada at 20 May 2015 is an almost-perfect example of the placement of recurring patches of open water polynyas that were present in the Canadian Arctic at this time of year in 1975-1979. Notes…

How Solar And Wind Are Causing Electricity Prices To Skyrocket

Watts Up With That?

Russia, the largest oil producer, wants the US to rely on wind and solar for energy.The following article was written by a leading environmental activist, who’s also running for governor of California, not some fossil-fuel advocate.

Guest essay by Michael Schellenberger

Over the last year, the media have published story after story after story about the declining price of solar panels and wind turbines.

People who read these stories are understandably left with the impression that the more solar and wind energy we produce, the lower electricity prices will become.

And yet that’s not what’s happening. In fact, it’s the opposite.
