Wind Farms
Large arrays of ind Turbines
W
: Take up little space
...
Farmers can sell the
electricity
generated from their
turbines
back to the local utility
An Underdeveloped Resource
Today, most large
energy
companies are developing plans to use more wind power
...
The Main problem with wind energy is
transportation
...
Biomass Power from living things
Biomass fuel consists of plant material, manure, and
any other organic matter
that is used as
an energy source
...
More than half of all wood cut in the world is used as
fuel for heating and cooking
...
This gas can be
burned
to generate heat or electricity
...
An example of this would be how landfills in the United
States generate electricity by using the methane from the decomposition of trash
Alcohol
Liquid fuels can be derived from Biomass such as
alcohol ethanol
and
which can be made by
fermenting fruit or agricultural waste
...
Gasohol produces less
air pollution
than do fossil fuels
...
This type of electricity is a
renewable resource
that accounts for about 20 percent
of the world's electricity
...
The benefits of Hydroelectricity
Hydroelectric dams are
expensive
to build, but they are
inexpensive
to operate
...
Dams also provide
other benefits such as flood control and water for drinking, agriculture, industry, and
recreation
...
A reservoir floods large
flow
areas of habitat above the dam
...
When the land behind the dam is flooded, people are often
displaced
...
Farmland may also be affected due to the fertile sediment build up behind a dam
instead of enriching the land farther down
Modern Trends
MicroHydropower: electricity produced in a
small stream
without having to build a big dam
...
MicroHydropower is much
cheaper
than large hydroelectric dam projects, and it
permits
energy to be generated from
small streams in remote areas
