History
Was used ever since humans discovered fireWas used as primary source for heat and
cooking until the industrial revolution, 1860’s
Primary Source
Crop residuesEnergy plantationsAnimal and industrial waste Needed fields of plants and trees to maintain
enough fuel to keep the plant running
Pro
Converts waste produced naturallyIn theory, fuel source can never run out Available all over the world and forms from
anythingCan be converted into liquid gases
Cons
Uses large areas of landLand use limits areaOveruse can cause deforestation Expensive to turn in to alcohols to make the
electricity Creates as much carbon dioxide as burning
fossils fuels
Environmental Effects
If not burned properly, then big contributor to global warming and greenhouse gases
Produces air pollution, and more environmental issues then any other form of producing electricity other then hydropower
Pollutants
Carbon dioxide Carbon monoxideHydrocarbonsOxygenated organicsFree radicals and chlorinated organics
Geographic Distribution
Anywhere there is plant life of animals areOne third of the worlds population burns
wood and other organic material.
Cost to Maintain
Maryland based 60 megawatt power plant cost approximately $250,000,000 to build
Annual biomass cost: $1,303,200
How It works
Needs the biomass form to workMany different types of ways to convert to
powerMost common is similar to a coal-burning
power plant First, gets turned into gases and it sent through filter Second, burned in boilers to create heat Next, heat turns water into steam Then, steam turns turbine connected to generator Finally, generator produces electricity and then is sent
to homes and businesses
How much is there?
Enough to replace all power created from nuclear energy, or replace half of nations gasoline use
We only use 7% each year to generate electricity
Resource Question #1
What are the different ways to convert to electricity? Thermal conversion Chemical conversion Biochemical conversion
Resource Question #2
How much profit do biomass plants earn each year? $5,000,000-$15,000,000 per year
