Car companies, starting with Volvo last summer, have laid out plans to electrify entire lineups of vehicles. But the fine print makes it clear that the coming decade and beyond will focus not just on massive battery packs powering electric motors, but also on adding a little extra juice to the venerable internal combustion engine.
Increasingly, that juice will arrive in the form of new electrical systems built to a 48-volt standard, instead of the 12-volt systems that have dominated since the 1950s. Simpler than Prius-type drivetrains and less expensive than Tesla-scale battery power, the new electrical architecture both satisfies the demands of cars made more power hungry by their gadget load and enables the use of lower-cost hybrid drive systems.

Huh? The heat produced by an oven light is nothing compared to that produced by the oven's heating elements. An LED light in an oven would be nice, as it would be much whiter and could be brighter than standard oven bulbs. But we don't have other lighting technology that works all that reliably at 500F, so we have to stick with bulbs for now.

He means with the main element off. If his bulb is 40 watts, he's using it as a 40-watt heating element.
We have lighting technology that works much hotter:

Lots of gas-discharge tubes will work fine. Mix them to obtain the desired color of light.
