Age of Electricity

Annual amount of electrical energy produced by countries of the world is here.

Leading source for generation of electric power for each US state, 2001 v 2019. Information used by NYT (10/28/20) in making these maps is from the US Energy Information Agency.

Rise of the Steam Turbine

80% of the world's electricity is produced through steam turbines.

So natural gas is replacing coal? Is this a good or bad thing for the country? I guess much of the transition has to do with anti-coal regulations.

[Boydstun]

MS, I gather that natural gas overtaking coal in so many states is mainly due to the greater amount of natural gas that became available with advances in fracking and horizontal drilling, making the price of natural gas more competitive for power plants. We have sulfur-dioxide emission limits, especially, also resulting in less generation by coal-fired plants. Fall in SO2 Emissions 2006-2015. (SO2 in the air is harmful to breathing and reduces visibility.) The States in which wind overtook coal for electrical generation may have been due to increase in number of wind-power generators. The cases in which hydro or nuclear overtook coal may have been possible due to buying power from others, including Canada.

A nuclear fuel pellet the size of a thimble can produce as much steam as 100 box cars of coal. Four boxcars will have been consumed in producing that pellet. However, the procedures and dollars required to ensure the lack of nuclear-power accidents that the US has enjoyed since TMI is enormous, and therefore nuclear cannot make the other types of fuel uncompetitive. It is a good point, of course, to not put all our eggs in one basket, and I'd say good also to not be drastically dependent on importation of fuels for power generation or on importation of electricity.

Germany hanging onto some nuclear generation a while.

[Boydstun]

France produces 70% of its electricity from nuclear, and it exports electricity to other countries. It can help other parts of Europe fulfill energy needs acutely in short supply for this winter, due to cutback of natural gas from Russia. At present 26 of France’s 56 nuclear reactors are off-line for maintenance and repairs. A huge scramble is underway to get that work buttoned up and get back on-line. President Macron’s administration has submitted a plan to Parliament to build six new enormous reactors in France starting in 2028.

California foolishly shuttered its San Onofre nuclear power plant after the Fukushima wreck. Although San Onofre was the same sort of reactor as Fukushima, the design basis for the San Onofre plant had been such that it would not have been breached by a tidal wave the size of the one that hit Fukushima. And the emergency diesel generators were elevated at the CA plant and would not have become inoperable, unlike at the Japanese facility.

Recently, the anti-nuclear movement in CA to close also Diablo Canyon, the state' last nuke, was blocked, with the governor's decision to keep it running and putting megawatts on the grid.
