Introduction
The search for alternative and eco-friendly energy sources is gaining ground amid ever-rising prices for conventional energy and increasing global attention to environmental issues. Agriculture, as a key sector of the global economy, is facing the need to trim the expenses and find ways for sustainable development. In this context, the use of small wind turbines in agriculture and at farms offers an innovative solution that can help both reduce dependence on conventional energy sources and substantially decrease the agricultural sector’s carbon footprint.
With their ability to generate electricity from renewable sources, small wind turbines are offering an increasingly attractive option for farms of various sizes. Their use helps to both meet the own electricity needs and promote the principles of green economy in agriculture. This, in turn, serves to improve the farms’ competitive edge, amplify their opportunities and opens up new prospects for sustainable development of rural areas.
This article aims to shed light on the opportunities of small wind turbine application in the agricultural sector, assess the economic viability and environmental rationale of their use on farms, and analyze lessons learnt from projects completed across the globe. We will review the technical aspects of small wind turbines, their advantages along with potential challenges related to their agricultural application; we are also going to outline prospective developments in this area in view of the global trends in the energy sector and green economy.
The approach involving the application of small wind turbines in agriculture is part of a broader sustainable development and green economy transition strategy implying adoption of environmentally-friendly technologies in conventional sectors. From this perspective, small wind energy provides both an alternative energy source and a powerful tool for achieving environmental sustainability and economic benefits amid of changing global energy trends.
Small Wind Turbine Technology
In the modern world, the technology of small wind turbines is becoming a key component in the sustainable development of agriculture and farming. The systems offer an eco-friendly and economically viable way to generate electricity, reducing dependency on fossil fuels and decreasing the carbon footprint. The technology is discussed in greater detail in another article (link).
FREEN is making a significant contribution to the development of this technology, offering a range of small wind turbines designed to meet a variety of needs. One such product is FREEN-20 —an ultra-lightweight vertical-axis wind turbine with flexible blades, which does not require reorientation in response to changes in wind direction. This model is ideal for agricultural applications due to its ability to operate efficiently under diverse wind conditions, starting with a minimum wind speed of 3.5 m/s and reaching maximum power at 17 m/s.
Key features of FREEN-20:
20 kW rated power output, capable for powering small and middle-sized farms.
Ability to operate both in grid-connected and off-grid energy systems, providing for a versatility of applications.
Low noise level and minimal environmental impact, which are critical factors for rural areas.
The use of small wind turbines, FREEN-20 in particular, at farms and in agriculture allows to both cut operational energy costs and enhance ecological sustainability of the production processes. Suitable for installation in diverse locations including remote and hard-to-reach places, these systems can provide a reliable energy source, curtailing the need for a connection to a central power grid.
FREEN endeavors to expand the applicability of its products, adapting them to the specific requirements of agriculture, which makes them one of the best choices for farmers seeking sustainable development and energy autonomy. The FREEN products’ efficiency, reliability, and environmental safety make them vital in the transition to renewable energy in the agricultural sector.
Examples of small wind turbine applications in agriculture
Adoption of small wind turbines in agriculture opens new horizons for farmers providing them with an additional source of revenue and facilitating sustainable development of the agrarian sector. The example of wind energy application at a farm in O’Neill, Nebraska, shows how wind turbines have become both sources of electricity and critical economic pillars for the local agricultural producers. Those farmers who have signed agreements for the wind turbine installation on their lands, receive annual payments, making them more resilient to climate and market fluctuations.
With the global installed capacity reaching 591,594 MW and an annual growth rate of about 9%, wind farms are becoming visible in our clean energy future. Countries like the USA, China, and the UK are actively developing wind farm usage, emphasizing their importance in achieving the carbon emission reduction goals and transitioning to renewable energy sources.
It should be noted that in addition to supporting energy independence and ecological sustainability, small wind turbines enable farmers to continue farming with a slight impact on land use. On average, wind turbines occupy only a quarter to half an acre of land, leaving more than 98% of arable land available for agricultural use. It shows that agriculture and wind energy can successfully co-exist to the benefit of both farmers and the environment.
Thus, small wind turbines represent a powerful tool for sustainable agricultural development, allowing farmers to both cut their energy costs and gain an extra income, while ensuring stability and opportunity for further development in the face of the present-day economic and environmental challenges.
Advantages of the use of small wind generators in agriculture
Eco-friendliness: Small wind turbines generate electricity without emitting carbon dioxide or other pollutants, which makes them an attractive option for reducing the ecological footprint of agricultural activities.
Energy cost reduction: Utilizing wind as an energy source helps farmers decrease their dependence on conventional energy sources and cut their electricity expenses.
Additional income: Hosting wind turbines on agricultural lands can provide farmers with an extra income through lease payments or sale of surplus generated energy.
Reliability and resilience: Wind energy reduces dependence on local and global fluctuations in energy prices, providing a steadier and more reliable energy source.
Support for sustainable development: Small wind turbines align with the concept of sustainable development in rural areas, facilitating the transition to green technology.
