close of all fission nuclear reactor in the world
Could you explain your logic?
Nuclear reactors predominantly produce electricity in the US. As I see
things, if the US shutdown all nuclear reactors, which produce 20% of US
electricity, this would shift US electric energy demands to other major
fossil fuel sources, such as coal, which produces 51% of US electricity, or
natural gas, which produces 17.5% of US electricity. Oil is heavily used
for transportation, but almost isn't used for electricity in the US (4% of
electric). Due to cost pressures, coal would be used. This 20% of
additional coal usage amounts to a 40% increase in coal usage. The serious
producers of energy are fossil fuels which increase greenhouse gas
emissions, acid rain, toxic metals, and other particulates in the air or
environment. Supposedly, the greenhouse gases contribute to global warming,
assuming we aren't seeing natural weather variation. Wind and hydroelectric
aren't serious power producers here or yet. The only other serious options
for electric energy are fusion reactors, black holes, undersea methane
hydrates, and geodynamo's. None of which have been perfected. The methane
hydrate is a fossil fuel... and at the bottom of the sea. People fear black
hole research will create of a black hole that will destroy the Earth.
Geodynamo's are under researched since they are about as close to a
"perpetual energy machine" as you can get. Fusion reactors have the same
problem as hydrogen fuel-cells: hydrogen doesn't exist in a pristine state
on Earth. I.e., you must use large amounts energy to create pure hydrogen
only to convert it back to energy... Unless you are able to extract far
more energy from the hydrogen than used in creating the hydrogen, you lose.
You also consume large quantities of hydrogen rich chemicals such as water,
methane, or methane hydrate, etc. which are needed by humanity for many
other chemical products.
