Agrivoltaics: A Sustainable and Ethical Approach to Energy and Agriculture – August 2024

Imagine a world where your morning coffee supports a farmer and generates clean energy. This isn’t a far-off dream – it’s the promise of agrivoltaics, an innovative approach combining solar panels with agriculture. As we face the challenges of renewable energy needs, sustainable farming, and ethical land use, agrivoltaics offers a compelling solution.

The ethical dilemma: food vs. energy? 

Should we use agricultural land for powering energy transition or ensure food security? Traditional agriculture and energy production often compete for land and resources. With the change in climate patterns and extreme weather events, crops face more stress than ever before. The climate aggression, coupled with higher production costs related to energy and water, the generational replacement of the farmers. The energy industry also competes for productive farmland because solar energy, being the cheapest energy source, requires space. This leads to a “food vs. fuel” conflict (Pearce et al., 2016). Agrivoltaics addresses this by enabling dual land use, and preserving farmland while generating renewable energy.

How agrivoltaics works: a harmonious integration

Agrivoltaics involves installing solar panels high enough for crops to grow underneath. This provides partial shade, reducing water evaporation and helping crops thrive in hot climates. By integrating energy production with agriculture, agrivoltaics conserves land and supports food security by simultaneously maintaining agricultural productivity and energy generation. Additionally, farmers receive extra income from selling solar energy, which supports rural communities and potentially slows urbanisation (Mavani et al., 2019). Unlike large solar farms that often disrupt ecosystems, agrivoltaics supports the coexistence of natural habitats with agricultural and energy production activities, sometimes enhancing biodiversity (Trommsdorff et al., 2024). The shade from panels also reduces evaporation, particularly beneficial in drought-prone areas where water usage in agriculture is a significant concern (Barron-Gafford et al., 2019).

Opportunities and challenges: paving the way forward

While agrivoltaics offers immense potential, its adoption faces several hurdles. High initial costs and complex implementation processes are significant barriers to widespread use. These challenges necessitate innovative financing models, policy support, and continued research to make agrivoltaic systems more accessible and cost-effective for farmers. Researchers estimate that installing agrivoltaic systems on just 1% of existing cropland could meet 20% of U.S. electricity generation (Adeh et al., 2019). Overcoming these hurdles could revolutionise how we ethically feed and power our world. Continued research and policy development are therefore crucial in creating a conducive environment for agrivoltaics to thrive and become a mainstream solution.

In conclusion, agrivoltaics is not just a technological innovation; but a major shift towards more ethical and sustainable practices in agriculture and energy. As climate change intensifies and land becomes scarcer, the dual benefits of agrivoltaics—clean energy production and resilient agriculture—make it an increasingly attractive option. That is why we founded Folgrid, a community-driven agrivoltaics company that helps connect farmers to nearby citizens and companies through the installation of micro-grids. Agrivoltaics can provide energy up to 50% cheaper than grid energy and reduce water consumption by up to 30%. Adopting agrivoltaics means embracing a future where our need for energy and water does not compromise our ability to produce sustainable food.
