Coal power
 
Just a little discouragement or encouragement.

They had 3 options.
Use less power, a lot less.
Keep their nuclear plants going
Burn more coal.

But fear and ignorance won.
They installed something to the tune of 10Gw of coal fired generating capacity in the last 5 years.
So much for saving the world.

The United States is taking 11.4Gw of coal power plants off line in 2018.

For when the link goes dead:

US utilities will take 11.4 GW of coal-fired power plant capacity offline in 2018, in spite of Trump’s orders. Why? Simple economics, explains Michael Buchsbaum.
His statement swept swiftly through the audience like a breeze of clean spring air.
“I will tell you it is not a matter of if we are going to retire our coal fleet in this nation, it’s just a matter of when,” said Ben Fowke, utility Xcel Energy Inc.’s chief executive officer, on stage at the Edison Electric Industry Group’s Annual Convention in San Diego, California on June 6th.
The company announced later that day in an electric resource plan that it wanted to retire two coal-fired units that produce a combined 660 megawatts (MW) of energy in Colorado and add 1,800 MW of capacity from renewable power, 275 MW of battery storage and another 383 MW of existing gas power.
Fowke was speaking just days after President Trump had ordered his Department of Energy to enact a legally dubious plan to halt the continued shuttering of more coal and nuclear plants in the name of national security. Indeed, a little over a decade ago, coal produced more than half of the electricity in the United States. But an unprecedented rate of plant retirements have cut that share to just 30.1% in 2017, and that number is swiftly spiraling downwards.
While coal producers, including major campaign contributor (and alleged co-author of the order) Murray Energy, cheered Trump’s directive, many within the industry remained skeptical. Despite the Republican Party’s rhetoric, producing energy from coal has become both increasingly unprofitable as well as technologically inefficient.
According to a report from S&P Global Market Intelligence, US power producers plan to take at least 11.4 GW of coal-fired power plant capacity offline in 2018, more than has been retired in a single year since 2015 (when 14.7 GW of coal capacity was retired). Another 19.8 GW of coal-fired power plant capacity is scheduled to go offline between 2018 and 2022. Moody’s Investors Service also calculates that some 35 gigawatts of capacity from coal and nuclear plants are now scheduled to be shut down over the next five years.
Indeed, since 2010, according to the industry-friendly American Coalition for Clean Coal Electricity, nearly 40% of the capacity of the nation’s fleet of coal-fired power plants has either been shut down or designated for closure. Additionally, more than a quarter of US nuclear power plants don’t make enough money to cover their operating costs, raising the threat of early retirements, according to Bloomberg New Energy Finance.
Once a massive burner of coal, Ohio-based American Electric Power Company Inc has retired some 7,200 MW of coal fired power since 2011. Even after Trump’s announcement, a spokesperson said the company was still likely to seek approval from regulators to shut its three-unit, 1,600MW coal-fired power plant in Conesville, Ohio if it doesn’t qualify for subsidies or “there are not other changes in the market,” company spokeswoman Tammy Ridout said in phone interview with Bloomberg.
“I think from our perspective we will continue moving toward a clean energy economy,” AEP Chairman Nicholas Akins related to Bloomberg. “When you look at the future and the investment potential and the risk associated with these investments by far the best approach is with natural gas, renewables and in fact technology.”
Why are all these utilities, despite Trump’s persistent pro-coal blather, bent on moving away from it? Economics. With the construction of 88% of the U.S. coal fleet dating back to before 1990, the plants are hitting or past their 40-50 year service life. And let’s face it: in order to fire a coal (or gas fired plant), you have to both buy and ship the resource to your plant. Neither the sun nor the wind sends you a bill for using it, and you don’t need trainloads of renewables to power your plant either.
“Certainly I think right now utilities are considering going forward with retirement plans as is,” Richard Glick, a member of the Federal Energy Regulatory Commission said told Bloomberg. “It’s pure economics. Gas prices are way down, renewable projects are getting much less expensive and they are beating other older technologies out in the markets.”
Renewable energy, while certainly not without overhead and maintenance costs, also simply doesn’t suffer from the same level of required tinkering. As Xcel wrote, while they could keep their coal plants in Colorado running, the clean energy proposal is more compelling because “it delivers lower costs along with substantial environmental and renewable energy gains.”
Moreover, the more renewable energy comes on line, the cheaper the costs. In January, Xcel released the results of a solicitation that returned a median price bid of $21 per megawatt-hour for wind-plus-storage projects and a median bid of $36 per megawatt-hour for solar-plus-storage. But in June the bids highlighted in Xcel’s new electric resource filing are even lower. Projecting “unprecedented low pricing”, it shows wind producing “at levelized pricing between $11-$18 per megawatt-hour, solar between $23-$27 per megawatt-hour, and solar-plus-storage between $30-$32 per megawatt-hour” according to the filing.
“We are making an enormous transition and renewables will play a big role in that,” said Xcel’s Fowke. “But to me, it’s not just renewables. The endgame is carbon reduction in the most affordable, pragmatic way possible.”

Maybe some one will buy it.
Trump signed an EO to encourage the development and retention of "strategic energy plants" power plants that can run for some while being cut off from refueling.
Power plants such as hydro, coal and nuclear.

I have once visited a coal-fired powerplant. At least the heavy ashes were collected and sent to a neighboring cement factory. Well, even though a nuke could eventually be cleaner if the safety measures are taken strictly, in a sh*thole country like mine I'd rather not mess with nuke and resort to something more conventional instead.

Duane Arnold Plant is licensed to 2034, Alliant Energy had a contract with them (Nextera - 70% owner) to buy 70% of their till then to 2025. But are buying out of it early (110 million) and Nextera is shutting the plant down in 2020. Alliant has a new deal with Nextera to buy wind power. Coal is Alliant main standby energy source in the 4 plants of theirs that I have been in.

Duane Arnold is like a hospital by comparison with a maximum security prison/military prison camp feel.

I had a job interview at a coal plant in Alabama owned by Southern Company. On the tour they bragged about sending the maximum amount of pollution allowed by law up the stacks. (It was an example of their keen business sense and responsibility to rate payers.)

No one's paying them to send up less.

All costs are passed down to the end consumer.

You forgot the other option they are pursuing - renewables. Renewables are by far the fastest growing segment of Germany energy production and currently stand at 33% of total production.

Yeah Germany is doing so well the only country beating them in the area of increased CO2 production is china.

Interesting. Never knew there were classifications of coal.
