The cost of lighting should drop because the fluorescent tubes use lower energy to obtain similar lumin
No, given the same lumen rating. Florescent lights are more electrically efficient than incandescent bulbs. Be careful, fluorescent bulbs currently contain mercury and should be handled and disposed of properly. For more information, you may also want to read. http://home.howstuffworks.com/question236.htm
If you increase the mass of an object, the potential energy will increase.
Solar energy is renewable. and it is a natural energy .
Energy is released and earthquakes happen.
When a wave's energy is lost to a surface, it is referred to as "dissipation." This process occurs when the wave interacts with the surface, leading to a conversion of wave energy into other forms, such as heat or sound, often due to friction or absorption. This can happen in various contexts, including sound waves hitting a wall or ocean waves breaking on the shore.
The entropy is changed.

sparks occur when the electrons are excited. This can happen by givong energy to electrons. Instead of city voltage, the magnetic fields or electromagnetic waves in air could give that energy.
Yes, as long as it is just incandescent bulb lighting connected to the track. If there is a transformer between the voltage source from the track and the light bulb (e.g. low voltage quartz bulbs) then these fixtures can not be dimmed.
not possible, as visible light photons have less energy and ultraviolet photons need more energy. Energy can neither be created nor be destroyed. So by conservation principle ultraviolet photon as they fall on fluorescent material could give out less energetic light photons, but the converse is not possible.
Nothing. Provided the earth remains in the same orbit, then a change of rotation would not change the amount of solar energy reaching the earth.
Nothing. For anything to happen at all, energy - more specifically, available energy - is required.
what happen to the heat energy as a substance solidifies
Farming
They havent really changed because nothing has happen to them.
Energy is necessary for things to happen
Energy is lost
