How far are electrical services required to be from windows on a residential home in USA?
In the USA the National Electrical Code prohibits the "point of attachment" of an overhead electric service to be within 36 inches of an openable window, doorway, or porch... in other words they do not want a person to be able to reach out of a building opening and be able to touch exposed live power wires. I believe this rule applies to all buildings not just residential. The "point of attachment" is the area near the top of the building's electrical conduit where the building wires are spliced to the utility company wires. This is the only area where there should be exposed power wires. There is no distance limitation from windows and doors for the remainder of the electrical service that has no exposed power wires, such as the conduits, meters, panels

Formula for calculating btu for a room metric?
Calculating your air conditioning requirementsHeat LoadThe amount of heat generated is known as the heat gain or heat load. Heat is measured in either British Thermal Units (BTU) or Kilowatts (KW). 1KW is equivalent to 3412BTUs.The heat load depends on a number of factors, by taking into account those that apply in your circumstances and adding them together a reasonably accurate measure of the total heat can be calculated.Factors include:The floor area of the roomThe size and position of windows, and whether they have blinds or shadesThe number of room occupants (if any)The heat generated by equipmentThe heat generated by lightingFloor Area of RoomThe amount of cooling required depends on the area of the room. To calculate the area in square metres:Room Area BTU = Length (m) x Width (m) x 337Window Size and PositionIf, your room has no windows, you can ignore this part of the calculation. If, however there are windows you need to take the size and orientation into account.South Window BTU = South Facing window Length (m) x Width (m) x 870North Window BTU = North Facing windows Length (m) x Width (m) x 165If there are no blinds on the windows multiply the result(s) by 1.5.Add together all the BTUs for the windows.Windows BTU = South Window(s) BTU + North Window(s) BTUOccupantsYou will have to take that into account people who normally working in the space. The heat output is around 400 BTU per person.Total Occupant BTU = Number of occupants x 400EquipmentClearly most heat in a room is generated by the equipment. This is trickier to calculate that you might think. The wattage on equipment is the maximum power consumption rating, the actual power consumed may be less. However it is probably safer to overestimate the wattage than underestimate it.Equipment BTU = Total wattage for all equipment x 3.5LightingTake the total wattage of the lighting and multiply by 4.25.Lighting BTU = Total wattage for all lighting x 4.25Total Cooling RequiredAdd all the BTUs together.Total Heat Load = Room Area BTU + Windows BTU + Total Occupant BTU + Equipment BTU + Lighting BTUThis is the amount of cooling required so you need one or more air conditioning units to handle that amount of heat.
How did invention of the electric light bulb change the environment?
You can see without a fire, or burning candles, oil lamps and lanterns, which can be dangerous left unattended. Also no need to wait for daylight to do all the work that we wish to do. We can work indoors in bad weather, even on small detailed tasks, and homes can be built with smaller/fewer windows to conserve energy. We can make plans to complete jobs, and they don't depend on daylight hours, or sunny weather to complete them, especially fine detailed work that requires clear sight. People can work all hours of the day and night, keeping hospital, or medical services, and police, or security services available to those who need it. One's life and work in general don't revolve around the time of day, and what the weather, or season may provide in the way of illumination.
