Microwave ovens costly as 7 million cars?

[elte]

Stove top cooking is I guess about ten times costlier than microwaving. With microwaving, all the energy enters the item while stovetop loses it around from under the pot and from the pot itself, and that is with a lid. It is important to ask the right questions in the first place. So Stove top is as costly as 70 million cars.

Environmental assessment of microwaves and the effect of European energy efficiency and waste management legislation

The team notes that the average operational life of microwaves – by far the most popular type of oven in Europe – has fallen by about five years in the past two decades, and continues to shrink. “Given that microwaves account for the largest percentage of sales of all types of ovens in the EU, it is increasingly important to start addressing their impact on resource use and end-of-life waste,” says Gallego-Schmid.

Planned obsolescence

At least they finally get around to mentioning what would be the real culprit or its remedy: The "decarbonisation of electricity" production in general. "Idle for 90% of the time" microwave ovens are just one electrical device among countless others (like space-heaters gobbling up the watts during the wintertime).

Which is greener, gas or electric cooking?

[...] The heat we feel from electric stoves traces back to coal-burning power plants [source: TreeHugger]. According to the Rocky Mountain Institute, this process spends three or four units of fuel in exchange for one unit of electricity [source: Cureton and Reed]. At the same time, gas stovetops are not environmentally perfect either, since they hook up to natural gas pipelines. [...]

The U.S. Department of Energy estimates that cooking accounts for 4.5 percent of the energy we use at home [source: U.S. Department of Energy]. Because that's a relatively tiny slice of our household carbon emissions, the question of whether a gas or electric stove saves more energy isn't a burning one for people looking to minimize their carbon footprints [source: American Council for Energy Efficient Economy].

Nevertheless, does one have any advantages over the other, particularly for the casual chefs among us? Because gas burners provide instant heat, and cooks have greater control over the temperatures, they're generally more energy efficient than their electric competitors [source: Directgov]. When you turn on a gas stove, you instantly get a flame, whereas electric stoves often take longer to heat and cool. Also, newer models that use an electric ignition rather than a continually-burning pilot light use up to 40 percent less gas [source: State of Minnesota].

That Cosmos link was the one I forgot, which I might have remembered but editing didn't work on this tablet.

I made insulated sleeves my cooking containers slip into, which makes it even more efficient.
