the sources of biomass energy are garbage, wood, waste, landfill gases, and alcohol fuels.
there are not just two electrical sources of energy there are lots but two could be solar and biomass
Biomass energy comes from a number of different sources. The main source of biomass is essentially the paper-manufacturing industry as the pulping liquor from the processes used to make paper contribute largely to the growing amount of biomass.In terms of the energy sources themselves, it would be best to refer to Wikipedia's article on biomass: http://en.wikipedia.org/wiki/Biomass#Biomass_sources. The section on Biomass Sources should provide all the information you need.
Petroleum
The energy sources that I am most excited about all have lower carbon emissions, compared to conventional energy sources. These include Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, and Hydroelectric Energy sources.

Conventional energy sources are coal, oil, natural gas, and hydraulic energy sources.Non conventional energy sources are nuclear, solar, wind, geothermal, wave, tide, and biomass energy sources.
