What are the possible consequenses of complete replacement of the sun and its enegy by electricity?how would life in general be affected if we use electricity for light,heat instead of the sun?

Elictricity is artificially generated and limited where as sunlight is unlimited sorce. Replacing sun by elecricity will not be enough to generate the essential energy required for photosynthesis and many other life processes.

"no sun = no life" True enough on earth, but what if the hypothetical situation was located on a different planet or space station?
anyway back to the question
If you think about it, almost all of our electricity is derived from the sun. Some of it is derived from orbit patterns and gravity effects of solar bodies, but ultimately in our galaxy that sums up to... the sun. Hydroelectric, for example relies on the hydrological cycle to run, which requires evaporation (mostly done by sun) and precipitation (caused by a combination of geology and complex air currents ultimately controlled by the sun and earth's gravity). Fossil fuels is an easy one, since we're just burning eons-old plant matter, which got its mass by harnessing the sun to bind carbon.
Nuclear power is a little more tricky. It's essentially the good ol' steam powered turbine we've always had, but the heat-source is fission... essentially a mini-sun.
