   I heat my home with wood now. A high efficiency woodstove with low particle emissions. If a dead tree rots in the woods it still releases a similar amount of CO2 into the air just like burning. But this CO2 was taken out of the air by the tree to begin with. Other plants and trees will use the released CO2. Problem with fossil fuels is they release trapped CO2 that will probably never get used.

   I will also soon be using solar panels to power DC lighting in my home.

   the new technology of the fuel cell its high efficient could be very small,the waste of it is pure H2o(water) vapor (fuel cell work by com paining h2 to O2 through special membrane and get electricity by the electron pass through circuit from H to O in order to complete reaction)
   in one step we can get electricity .
   the disadvantage :these cell are not commercially produced yet and the need some modification for practical use.
