As coal use surges, America finds it's hard to unplug from carbon | TheHill
As coal use surges, America finds it's hard to unplug from carbon | TheHill

Hate coal if it makes you happy, but the reality is that power producers have relied on it ever since Thomas Edison used it to fuel the world’s first central power plant in Lower Manhattan in 1882. Indeed, the jump in domestic consumption is part of a surge in global demand for coal, which still accounts for about 36 percent of global electricity generation. Last month, the International Energy Agency reported that “global coal power generation is on course to increase by 9 percent in 2021 to 10,350 terawatt-hours (TWh) — a new all-time high.” The agency also reported that “coal demand may well hit a new all-time high in the next two years.”

Plausible 2005-2050 emissions scenarios project between 2 and 3 degrees C of warming by 2100 - IOPscience

These scenarios project between 2 and 3 degrees C of warming by 2100, with a median of 2.2 degrees C. The subset of plausible IPCC scenarios does not represent all possible trajectories of future emissions and warming. Collectively, they project continued mitigation progress and suggest the world is presently on a lower emissions trajectory than is often assumed. However, these scenarios also indicate that the world is still off track from limiting 21st-century warming to 1.5 or below 2 degrees C.

China plays an essential role in any global climate solution | TheHill

Duh. It is remarkably how much CO2 China generates and the figure continues to grow as other countries make some effort to limit or even reduce (somewhat) their amounts.

China increased emissions since 2005 by around 70 percent, currently producing nearly 14 gigatons of CO2. In comparison, U.S. annual output is around five gigatons. The U.S. accounts for around 11 percent of global emissions, while China comes in at 27 percent.

New Nuclear Power Plants Are Unlikely to Stop the Climate Crisis - Scientific American

The exercise offered both bad news and good. The bad news is that keeping the rise in temperature below 2° C is going to be very hard and holding it under 1.5° probably impossible. The good news is that the challenge can be met—if we implement a large portfolio of solutions, the most important of which are eliminating fossil-fuel subsidies and putting a stiff price on carbon.

OK, so this approach obviously makes power much more expensive, but how can it do something about climate change? The details were not mentioned, it talks about nuclear not being part of the solution, which basically leaves wind and solar. I would love to see the projections on how W&S are going to do something significant in the near term.

Georgia Power plans to double renewables, ditch all coal - E&E News (eenews.net)
Georgia Power plans to double renewables, ditch all coal - E&E News (eenews.net)

Georgia Power plans to shutter 12 coal units, totaling about 3,500 megawatts, by 2028. It wants to replace that electricity with a combination of renewables as well as 2,356 MW of natural-gas-fired power that it plans to buy from power plants that are already running. For context, once two additional nuclear reactors at Georgia Power’s Plant Vogtle start producing electricity, the total 4,536 MW from four units there will power up to 1 million homes.

Now do India.

India is getting up there of course, still shy of the US, but growing.

China emitted 27% of the world's greenhouse gases in 2019. The US was the second-largest emitter at 11% while India was third with 6.6% of emissions, the think tank said.

57 degrees here in the banana belt - 40s for the 10-day forecast with no precip in sight

gonna make it halfway through Feb with VERY little winter weather!!! Which is nice

May be an image of snow and text that says 'STORM TEAM Least Snowfall In Sioux City Through February 6th 2021-2022 1933-1934 1899-1900 1912-1913 1967-1968 1967- 3.4" 5.6" 6.2" 6.3" 6.4"'

European fusion reactor sets record for sustained energy | Science | AAAS

In experiments culminating the 40-year run of the Joint European Torus (JET), the world’s largest fusion reactor, researchers announced today they have smashed the record for producing controlled fusion energy. On 21 December 2021, the U.K.-based JET heated a gas of hydrogen isotopes to 150 million degrees Celsius and held it steady for 5 seconds while nuclei fused together, releasing 59 megajoules (MJ) of energy—roughly twice the kinetic energy of a fully laden semitrailer truck traveling at 160 kilometers per hour. The energy in the pulse is more than 2.5 times the previous record of 22 MJ, set by JET 25 years earlier. “To see shots in which it sustains high power for a full 5 seconds is amazing,” says Steven Cowley, director of the Princeton Plasma Physics Laboratory (PPPL).

JET’s achievement doesn’t mean fusion-generated electricity will flow into the grid anytime soon, however. Researchers had to put roughly three times as much energy into the gas as the reaction produced. But the result gives them confidence in the design of ITER, a giant fusion reactor under construction in France, which is supposed to pump out at least 10 times as much energy as is fed in. “This is very good news for ITER,” says Alberto Loarte, head of ITER’s science division. “It strongly confirms our strategy.”

Cold here again.

Should hit mid 70s here over the next couple days. Overnight lows down into the low 40s though. Typical Feb for us.

Started off at 43, but will peak at 74 later. Big swing.
