Not only were greenhouse heated from the engery produced by the sun but also by heat from paraffin heaters and heated water pipes heated by coal or wood fires.
Hawaii is the only state in the USA that has significant coffee production. Coffee is grown in small quantities in a few other states. Coffee has been grown as far north as Iceland, using greenhouses heated by volcanic steam.
Candles and gas lanterns were used at night before electricity.
No. Electricity was around long before Ben Franklin -- or humans for that matter.
Franklin's experiment was merely to prove that lightning was electricity, not to prove that electricity existed. Hence, the name "Father of Electricity" is inaccurate. Electricity was known to exist at least a century before Benjamin Franklin conducted his kite experiment; various mechanisms for the manipulation, creation and storage of electricity had been invented, such as static electricity generators and Leyden jars.

Before electricity, people heated their homes using fireplaces, wood-burning stoves, coal stoves, and oil lamps. These sources of heat provided warmth and light for cooking and heating water.
All bananas consumed in Iceland are imported but some are grown for experimental purposes in geothermally heated greenhouses at the Horticultural institute.

Rainbow Greenhouses was created in 1985.
Rainbow Greenhouses's population is 150.
No single piece of metal will produce electricity when heated. You will need two different metals, mechanically touching. When the join between the metals is heated, it will produce electricity, dependant on the metals used. This is known as a 'thermocouple'.
Water heated by the sun can be used to create electricity through a process called solar thermal power generation. In this process, the heated water is converted into steam, which drives turbines connected to generators to produce electricity. This is a renewable energy source that utilizes the heat from the sun to generate power.

Ultra Violet or U.V. rays are communly used to get what is communly known as a "Tan" though they are also communly used to heat greenhouses and also to provide power using "Solar Panels" which use Silicon, which producess electricity when heated, to produce vary offten times Large yeilds of electrical charge.
When copper is heated it oxidizes. The additional oxygen molecules it takes on when oxidizes leads it to have a higher mass.
That would depend upon whether the greenhouse is in use, and whether it is being heated, and how. Greenhouses heated with propane will release CO2. Greenhouses not in use may emit various gases, depending upon the state of decomposition of any organic material contained within them. In general, an unheated (or solar heated) greenhouse in use will tend to emit oxygen, via photosynthesis activity of the plants contained within it.
