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
