Bumblebees buzz from flower to flower, stopping for a moment under a clear blue Minnesota sky. Birds chirp, and tall grasses blow in the breeze. This isn’t a scene from a pristine nature preserve or national park. It is nestled between photovoltaic (PV) solar arrays on rehabilitated farmland.
Researchers at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and National Renewable Energy Laboratory wanted to understand the ecological value of PV solar energy sites planted with native grasses and wildflowers. They examined how vegetation would establish and how insect communities would respond to the newly established habitat. The five-year field study looked at two solar sites in southern Minnesota operated by Enel Green Power North America. Both sites were built on retired agricultural land.
Smart land use choices provide multiple benefits
Global insect biodiversity has been in decline due to habitat loss, pesticides and climate change. Restoration of insect habitat paired with smart land use changes toward renewable energy developments could help reverse the course.
For instance, as a carbon-neutral source of electricity, expanded PV solar energy development is critical to mitigating climate change. According to the DOE’s Solar Futures Study, approximately 10 million acres of land in the U.S. will be needed for large-scale solar development by 2050 in order to meet grid decarbonization and climate change goals. But some lands are better suited for PV solar development than others. Disturbed lands such as former agricultural fields are ideal locations to hold rows of solar panels compared to lands that have been previously undisturbed.
Even more strategies can be added to this winning combination to support insect conservation. Agrivoltaics is the combination of solar energy production with agricultural and vegetation management practices. One type of agrivoltaics focuses on the establishment of habitat for insect pollinators and other wildlife that can provide important ecosystem services, such as pollination. Pairing solar energy facilities on previously disturbed lands with habitat enhancement sounds like a logical win-win strategy to address energy and biodiversity challenges. To date, however, there has been little field data available to document the feasibility and the ecological benefits of this novel land use approach.
If you build it, will they come
The two studied solar sites were planted with native grasses and flowering plants in early 2018. From August 2018 through August 2022, the researchers conducted 358 observational surveys for flowering vegetation and insect communities. They evaluated changes in plant and insect abundance and diversity with each visit.
“The effort to obtain these data was considerable, returning to each site four times per summer to record pollinator counts,” said Heidi Hartmann, manager of the Land Resources and Energy Policy Program in Argonne’s Environmental Sciences division, and one of the study’s co-authors. “Over time we saw the numbers and types of flowering plants increase as the habitat matured. Measuring the corresponding positive impact for pollinators was very gratifying.”
By the end of the field campaign, the team observed increases for all habitat and biodiversity metrics. There was an increase in native plant species diversity and flower abundance. In addition, the team observed increases in the abundance and diversity of native insect pollinators and agriculturally beneficial insects, which included honeybees, native bees, wasps, hornets, hoverflies, other flies, moths, butterflies and beetles. Flowers and flowering plant species increased as well. Total insect abundance tripled, while native bees showed a 20-fold increase in numbers. The most numerous insect groups observed were beetles, flies and moths.
In an added benefit, the researchers found that pollinators from the solar sites also visited soybean flowers in adjacent crop fields, providing additional pollination services.
The benefits of solar-pollinator habitats
“This research highlights the relatively rapid insect community responses to habitat restoration at solar energy sites,” said Lee Walston, an Argonne landscape ecologist and environmental scientist who was lead author of the study. “It demonstrates, if properly sited, habitat-friendly solar energy can be a feasible way to safeguard insect populations and can improve the pollination services in adjacent agricultural fields.” Walston also serves as head of the Ecology, Natural Resources, and Managed Systems department in Argonne’s Environmental Science division.
The research findings suggest two important implications of habitat-friendly solar energy. One is that habitat-friendly solar sites can play an important role in conserving biodiversity. Large amounts of ground-mounted solar is expected to be developed in the future, but if properly sited, habitat-friendly solar can offset the losses of natural areas to provide biodiversity benefits.
Second, habitat-friendly solar sites can help mitigate land-use conflicts associated with the conversion of farmland for solar energy production. As approximately 80% of future ground-mounted solar development could occur on agricultural lands, the proper siting of habitat-friendly solar energy on marginal farmland can not only preserve prime farmland, but it could make prime farmland more productive through the pollination services provided by habitat-friendly solar energy.
Overall, additional research is needed to understand the feasibility of habitat-friendly solar across different regions and to meet different ecological goals such as conserving a target insect or wildlife species.

Argonne to lead National Energy Storage Research Hub
by Clarence Oxford
Los Angeles CA (SPX) Sep 05, 2024
The U.S. Department of Energy (DOE) has selected Argonne National Laboratory to lead the newly established Energy Storage Research Alliance (ESRA), a national hub focused on advancing energy storage technologies. The ESRA, co-led by DOE’s Lawrence Berkeley National Laboratory (Berkeley Lab) and Pacific Northwest National Laboratory (PNNL), is one of two new Energy Innovation Hubs announced by the DOE.
Bringing together nearly 50 leading researchers from three national laboratories and 12 universities, ESRA aims to address the most critical challenges in battery technology, such as safety, high-energy density, and the development of long-duration storage solutions using cost-effective and abundant materials. The initiative is designed to push the boundaries of energy storage science, fostering innovation and strengthening the competitive edge of the U.S. in this crucial field.
“The demand for high-performance, low-cost and sustainable energy storage devices is on the rise, especially those with potential to deeply decarbonize heavy-duty transportation and the electric grid,” stated Shirley Meng, ESRA director and chief scientist at the Argonne Collaborative Center for Energy Storage Science. “To achieve this, energy storage technology must reach levels of unprecedented performance, surpassing the capabilities of current lithium-ion technology. The key to making these transformative leaps lies in a robust research and development initiative firmly grounded in basic science.”
Leveraging decades of investment in fundamental science, ESRA will focus on transformative discoveries in materials chemistry, a deeper understanding of electrochemical processes at the atomic level, and establishing the scientific foundations necessary for major advancements in energy storage technology.
“ESRA creates an energy storage research ecosystem with the mission to rapidly innovate, shorten the time between basic discovery and technology development, and train the next-generation workforce,” commented Bryan McCloskey, ESRA deputy director for scientific thrusts and a faculty engineer at Berkeley Lab.
The success of ESRA’s efforts will lead to the development of high-energy batteries that are fire-resistant, capable of providing long-duration storage for multiple days, have a lifespan of several decades, and are constructed from low-cost, widely available materials.
“ESRA will pave the way for innovative energy storage solutions that drive both U.S. prosperity and security,” said Argonne Director Paul Kearns. “As the lead laboratory for ESRA under the Department of Energy’s Office of Science, Argonne takes pride in spearheading this collaborative effort that unites world-leading experts and taps the impressive scientific resources available in national labs and academia.”
The DOE has committed up to $62.5 million in funding for ESRA over the next five years.
In addition to its research goals, the Argonne-led hub will prioritize training a diverse, next-generation battery workforce to meet future manufacturing demands. This will be achieved through innovative training programs that involve industry, academia, and government partnerships.
“Cultivating a diverse workforce dedicated to safeguarding America’s energy resilience is key to ESRA’s mission,” noted Wei Wang, ESRA deputy director for crosscuts and director of the Energy Storage Materials Initiative at PNNL. “Through our strategic equity and inclusion initiatives, we plan to create a robust training ground for energy storage science from the undergraduate to postdoctoral levels.”
With Berkeley Lab and PNNL as co-leads, the ESRA collaboration brings together comprehensive expertise across the energy storage spectrum. Their state-of-the-art capabilities in technology discovery, modeling and simulation, and materials synthesis and characterization complement those of Argonne, setting the stage for significant advancements in energy storage.
Argonne is joined by 14 partners in this initiative, all of whom are deeply involved in ESRA’s scientific endeavors, governance, strategic development, and the training of the next generation of battery scientists and engineers. This collaboration among national laboratories and universities is vital for discovering new materials, accelerating the development of technology, and commercializing new energy storage innovations.

UN’s Guterres says China-Africa ties can drive ‘renewable energy revolution’
by AFP Staff Writers
Beijing (AFP) Sept 5, 2024
United Nations Secretary-General Antonio Guterres told African leaders Thursday that expanding ties between China and the continent could “drive the renewable energy revolution”.
Guterres and more than 50 African leaders are attending this week’s China-Africa forum, according to state media.
Guterres told the gathering that “China’s remarkable record of development — including on eradicating poverty — provides a wealth of experience and expertise”.
“It can be a catalyst for key transitions on food systems and digital connectivity,” he said.
“And as home to some of the world’s most dynamic economies, Africa can maximise the potential of China’s support in areas from trade to data management, finance and technology,” Guterres added.
Guterres also told the leaders it was time to correct “historic injustices” against the continent.
“It is outrageous… that the continent of Africa has no permanent seat on the Security Council,” he said.

Major Qatari plant to double solar capacity by 2030: minister
by AFP Staff Writers
Doha (AFP) Sept 1, 2024
A large new solar plant planned in Qatar will double the Gulf emirate’s previously projected renewable energy capacity by 2030, Qatari Energy Minister Saad al-Kaabi announced on Sunday.
The photovoltaic farm, which will be built in the Dukhan area some 80 kilometres (50 miles) west of the capital Doha, will increase the gas-rich state’s solar production capacity to four gigawatts by the end of the decade, Kaabi said.
The plant “that will be established in Dukhan area will produce 2,000 megawatts, which is twice more than the capacity of Qatar’s production of solar energy of the current projects,” the minister, who is also chief executive of state-owned QatarEnergy, said.
In October 2022, Qatar inaugurated its first large-scale solar farm at al-Kharsaah, west of Doha. The emirate announced in August of the same year another solar project with two plants at Ras Laffan in the north.
Through the combined projects, including at Dukhan, Qatar would achieve “4,000 megawatts of clean energy by 2030”, Kaabi said.
This will “constitute 30 percent of the total production of energy of the state of Qatar” with a yearly reduction of “4.7 million tonnes of CO2 emissions,” he added.
Kaabi said the existing projects should produce 1.7 gigawatts of energy “in first quarter of next year, or early next year”.
The energy minister also announced plans to more than double Qatar’s urea production making the country the largest producer of the fertiliser in the world by the end of the decade.
He said Qatar would “maximise the production of chemical fertilisers” through “a complex with global standards” which would “increase our production capacity from 6 million tonnes annually to more than 12.4 million tonnes annually”.
Qatar is one of the world’s top liquefied natural gas producers alongside the United States, Australia and Russia. Natural gas is a major ingredient in urea manufacturing.
In February, Qatar announced plans to expand its output from its North Field project, saying it will boost capacity to 142 million tonnes per year before 2030.
Over the past year, Qatar has inked a series of long-term LNG deals with France’s Total, Britain’s Shell, India’s Petronet, China’s Sinopec and Italy’s Eni among others.
