Wind, Biomass Energy
Other forms of clean energy include wind and biomass.
Windmills were used extensively in Northwestern Europe to grind flour as early as the 12th century, and were used for water pumping in early American farming and ranching. Today’s windmills or “wind turbines,” harvest the power of wind to create renewable energy.
Wind turbines typically use two or three long blades that spin to collect wind energy and power a pump or turn a generator to produce electricity that is stored in batteries.
Most wind power is produced at wind farms, facilities that are carefully placed in windy locations. As a renewable energy, wind is non-polluting and produces no emissions or chemical waste.
How Wind Works to Produce Energy
The blades of the wind turbine are attached to a shaft or pole. The pole is attached to gears which are used to spin a generator. The generator produces the electric current which is then carried away and begins its journey to our homes and businesses.

Biomass is a renewable energy that is produced from burning organic matter such as wood, paper, tree trimmings and waste from mills. Once these products are burned, the heat produced turns a steam turbine, which moves a generator to produce electricity.
Biogas (landfill and sewage)
Biogas is created when microorganisms cause organic waste, such as food wastes and paper, to decompose in landfills. When organic matter decomposes landfill gas is produced. In biogas energy projects, landfill gas is burned in boilers, reciprocating engines, and combustion turbines to produce electricity.
Biogas is used in many different ways worldwide.
- In very small communities biogas is used for single-household cooking and lighting.
- Large-scale biogas use produces electricity, heat and steam, chemical production, and vehicle fuel.
