How can farmers benefit from wind energy and agriculture?

In looking to blend wind energy and agriculture farmers have the chance to increase their income whilst providing the space to implement the technology. Across the world, we now generate a total of 591,594 MW from wind power. While this is only a percentage of the total, wind power is growing by around 9% each year.

What happens to the energy used in agriculture?

A part of the direct, indirect and solar energy used in agriculture is transformed into produce storing it as chemical energy. The rest of the energy is wasted. In the case of direct energy, it is wasted as heat of the machinery used, indirect energy is wasted as fertilizers and pesticides miss their target.

What is wind energy used for?

Humankind has been using wind energy since ancient times – for sailing, water pumping and grinding. Modern technology, such as a wind turbine is now used also for electricity production in many parts of the world.

How does a wind energy system generate electricity?

The power output of a wind energy system is generally estimated by multiplying the available wind speed by the swept area of the rotor. The rotational force can be used either directly (irrigation pumps etc.) or to drive a generator and produce electricity (Find an animation of a wind pump here ).

How does agriculture use energy?

Agriculture uses energy directly as fuel or electricity to operate machinery and equipment, to heat or cool buildings, and for lighting on the farm, and indirectly in the fertilizers and chemicals produced off the farm.


How does wind energy affect farmers?

Each wind turbine can take up less than half an acre of land, often far less than what would be needed for a solar farm. It is possible for farmers to plant crops and graze livestock right up to the base of the turbines and therefore make use of about 95% of the land in the immediate area around the turbine.


How does a wind turbine help crops?

Wind turbines help crops by channelling beneficial breezes over nearby plants. Summary: Researchers have found that wind turbines benefit nearby crops, keeping them cooler and drier and boosting the uptake of carbon dioxide. Wind turbines in Midwestern farm fields may be doing more than churning out electricity.


How do farmers feel about wind turbines?

Farmers and ranchers receive steady income from wind projects that helps them ride through down times in agriculture markets. These projects can even help keep farms in the family for another generation.


How is wind energy used?

Today, wind energy is mainly used to generate electricity. Water-pumping windmills were once used throughout the United States, and some still operate on farms and ranches, mainly to supply water for livestock.


Why is wind important in agriculture?

Wind direction and velocity have significant influence on crop growth. Wind increases the turbulence in atmosphere, thus increasing the supply of carbon dioxide to the plants resulting in greater photosynthesis rates. Wind alters the balance of hormones. Wind increases the ethylene production in barley and rice.


How does wind help agriculture?

Wind generation in agriculture is beneficial in that pairing wind with agriculture leads to a virtuous cycle, in which the additional income generated by the turbines can be reinvested back on the farm. According to a survey conducted by the University of Michigan in 2014, landowners with wind turbines on their property invested twice as much money in their farms over the last 5 years compared with their neighbors without wind turbines. These investments went toward improving aspects of the farming operation such as farm equipment and irrigation and toward buying more farmland. While landowners with turbines may already be in a better financial position or more likely to experiment with new farming methods, these results still show that wind turbines have the potential to improve the land in the long term by allowing famers to invest more in their farms.


Can solar power be used in agriculture?

But not only solar pairs well with agriculture. The colocation of wind energy and agriculture can also be beneficial to farmers by generating additional income and serving as a means of insurance, thanks to the stable income it can provide.


How has wind energy been used?

Humankind has been using wind energy since ancient times – for sailing, water pumping and grinding. Modern technology, such as a wind turbine is now used also for electricity production in many parts of the world.


How many hours a year does a wind turbine run?

One can see that a wind speed of about 5 m/s occurs more than 1000 hours a year, while stronger wind speeds are less frequent throughout the year. The second input for calculating the annual energy yield of a wind turbine is the power curve of the wind turbine .


How do wind pumps work?

Wind pumps are one of the first applications for using nature’s power to improve agricultural processes. Already in the 9th century, they were used to irrigate fields or to drain the land. Nowadays the technology is mostly used where a grid connection is too far away and wind conditions are steady enough to provide a reliable pumping solution. The design of a wind pump always depends on the application. Firstly, a distinction between mechanical and electrical wind pumps has to be made. Electrical wind pumps normally have the disadvantage of a lower efficiency, but pumps can be placed away from the location of the wind turbine. To choose the right wind turbine considerations about the desired pumping technology and extraction depth have to be made upfront. Centrifugal pumps generally work better with faster rotating wind turbines while piston and diaphragm pumps work better with slow rotating turbines.


Which pump works better for wind turbines?

To choose the right wind turbine considerations about the desired pumping technology and extraction depth have to be made upfront. Centrifugal pumps generally work better with faster rotating wind turbines while piston and diaphragm pumps work better with slow rotating turbines.


When were wind pumps used?

Already in the 9th century , they were used to irrigate fields or to drain the land. Nowadays the technology is mostly used where a grid connection is too far away and wind conditions are steady enough to provide a reliable pumping solution. The design of a wind pump always depends on the application.


What is the difference between wind pump and electrical wind pump?

Firstly, a distinction between mechanical and electrical wind pumps has to be made. Electrical wind pumps normally have the disadvantage of a lower efficiency, but pumps can be placed away from the location of the wind turbine.


Background – Agricultural Connections

Humans first harnessed the wind over 7,000 years ago to navigate the Nile River. Today, wind technology produces over 250 GW of electricity a year and helps farms with remote power needs and sustainability efforts. 250 GW (gigawatts) is the approximate annual global production of wind power.


Interest Approach or Motivator

As students enter the classroom have them watch the brief video on wind turbines https://youtu.be/YzgWUzTKYIs.


Procedures

Objective 1: Understand that there are different types of power that can be harnessed from the wind.

Using the website www.windustry.org (and its various links) have students design a hypothetical wind project and identify available financial incentives for their region and chosen project.


Agriculture Literacy Outcomes

Describe resource and conservation management practices used in agricultural systems (e.g., riparian management, rotational grazing, no till farming, crop and variety selection, wildlife management, timber harvesting techniques)


Common Core Connections

RI.9-10.IA.1: Employ the full range of research-based comprehension strategies, including making connections, determining importance, questioning, visualizing, making inferences, summarizing, and monitoring for comprehension.


How do farmers get their own power?

Farmers and ranchers can generate their own power from the wind, just as their predecessors did in the 1930s and 1940s. Small wind generators, ranging from 400 watts to 40 kilowatts or more, can meet the needs of an entire farm or can be targeted to specific applications. In Texas and the West, for example, many ranchers use wind generators to pump water for cattle. Electric wind generators are much more efficient and reliable than the old water-pumping fan-bladed windmills. They may also be cheaper than extending power lines and are more convenient and cheaper than diesel generators.


How much is wind royalty?

and mostattractive to benefit from wind power is to allow developers to install large wind turbines on their land. The royalties are typically around $2,000 per year for each turbine. These payments can provide a stable supplement to a farmer’s income, helping to counteract swings in commodity prices.
