I dont think any homes are solely solar powered, the sun is obviously not always out so we would be left with nothing usable. I think what happens is solar panels are fitted to houses so that when there is enough sunlight they will be able to use solar energy. There are 25 solar cities now in America but not nearly enough funding if you read up on it, apparently this is due to the US government not taking energy saving as seriously as the rest of the western world. I hope this helps although Im not an expert on the subject nor an American, Im just going with what I have read.
For overall, base on the data from EIA in 2011, 9% of US energy consumption come from renewable resource. Of the 9%, the fraction of Solar energy including PV and Solar Thermal accounted to 2% of total renewable energy. It is only 0.18% of US energy consumption coming from Solar energy.
For electricity, it is reported that 1.8% of the electricity come from Solar energy including PV and Solar Thermal.
It currently powers very little of our needs and hopefully could power as much as 1 or 2 %.

fast energy flow in the biomass
Biomass production is basically burning organic material to produce energy. Biomass energy is generally clean and is a renewable resource.
No, biomass is just an organic matter.
biomass
A biomass pyramid looks like an energy pyramid, in that the largest biomass is contained in the producer level, and the least biomass is contained in the level of the highest order consumer. Basically, as you move up the energy pyramid, there is less energy available to support the biomass at each subsequent level.

It is in Maryland
Nuclear is about 16 percent of total world output. I'm not sure about hydro and biomass but they are 7 percent and 1.3 percent in the US
biomass
Energy from biomass is released by combustion.
Biomass energy produces 3% of the worlds energy
no one uses biomass energy
Biomass
Biomass energy is widely used. One state that uses biomass is Oregon.
In the U.S., biomass today provides about 3-4% of primary energy. Biomass is used for heating wood stoves, cooking, transportation, and for electris power production.

biomass energy is located everywhere on this planet!
