That varies a lot, depending on the specific metal, and from what raw materials it is extracted.

Heat and light. The metal filament heats up to the point of incandescence in the visible part of the spectrum.
Strontium
.50 per sq.ft
Yes, Usually it absorbs water of 0.5% to 1 % max. This is used for correcting the water content used for producing the mix concrete.
The energy cost of producing metals from minerals varies depending on the specific metal and the extraction process used. Generally, mining and processing metals from their ore is energy-intensive due to the need for crushing, grinding, and smelting. Renewable energy sources are being explored as a more sustainable option for reducing the energy cost of metal production.
If you heat metal sufficiently, it will glow, which is an emission of energy, however that energy comes from the heat energy you have added to the metal; the metal itself is not producing energy.
The energy cost of producing metals from ingots can vary depending on the metal and the specific production processes used. Generally, mining and refining metals can be energy-intensive processes due to the need for extracting, transporting, and processing raw materials. The energy cost is also influenced by factors such as the efficiency of the production methods and the source of energy used.
No one answer. It would depend on the gold content of the mineral. The higher the gold content, the lower the energy cost. The deeper the mine, the higher the cost.
Producing energy.
Efficiency in terms of energy means accomplishing processes with less energy, ideally the least energy required, with a minimum of waste. Ordinarily, this means that the cost of producing energy is less. However, some methods of efficiently producing and using energy are not the cheapest in terms of the other costs involved: some would cost more to implement, and more to maintain, such as low-resistance shielded transmission lines, which could cost vastly more initially than cheaper ones and cost more to maintain and repair. It would be energy efficient but not cost efficient.
When electric currents flow through the metal filament of a light bulb, electric energy is converted to light and heat energy. The filament heats up due to the resistance in the metal, eventually producing light as it emits photons.
The cost of hydroelectric energy production varies greatly depending on factors such as location, size of the project, and construction costs. On average, the cost of producing hydroelectric energy can range from $0.03 to $0.09 per kWh.
Metal roofs cost about three times the amount of conventional asphalt roofs. Several factors contribute to cost, including higher cost of the materials themselves. The installation process also drives up the cost due to time involved as well as the process, which requires specialized installation technicians. Metal roofs take approximately two to three times longer to install. Although costlier than asphalt roofs, metal roofs are comparable in price to cedar shake and tile roofing. Metal roofs, however, are cooler, producing energy savings that will eventually offset materials and installation costs.
No, chloroplasts are the energy producing part of plants.
No, saving is not the same as producing. Saving means taking what's already there and making it go further. Producing means actually making energy.
