Not necessarily. Imagine how cheap it would be, with unlimited power, to turn large areas of land into mirrors. Just find any sandy area such as a desert, then melt it smooth, then sputter on some shiny metal. I don't know the statistics on the amount of energy in sunlight falling on the earth, but it's some amazing number of times greater than the amount of energy we use. In other words, we could compensate for all the energy we use by covering a relatively small part of the earth's surface with mirrors to reflect all the heat back out into space. The greenhouse effect probably traps much more heat than would be produced by any fusion we could use. Worrying about a "furnace effect" from fusion is almost as groundless as worrying about one from solar energy.
