Solar Farms Help Bees: Solar Installations for the Bees

Solar Farms Help Bees: Solar Installations for the Bees

Solar farms help bees: Solar farms emerging as sanctuaries for declining wild and honey bee populations.

In an unexpected turn, solar farms help bees and are emerging as potential sanctuaries for declining bee populations, providing a secondary purpose beyond clean energy generation. A recent study reveals that strategically planting native flowers and grasses around solar installations significantly enhances the population and diversity of crucial pollinators like bees, offering a promising avenue for both clean energy expansion and environmental conservation.

Research conducted by scientists from the Department of Energy’s Argonne National Lab, in collaboration with the National Renewable Energy Lab, focused on assessing the impacts on insects from two large solar installations situated on retired farmland in Minnesota. Enel Green Power North America, the operators of these solar sites, undertook the initiative to plant wildflower mixes alongside the panel arrays during construction in 2018. The researchers then conducted comprehensive year-round insect surveys at these facilities from 2018 to 2022.

The findings from the study are nothing short of remarkable; solar farms help bees. Over the five-year observation period, both native bee and monarch butterfly populations increased more than twenty-fold. The areas surrounding the solar panels transformed into thriving, prairie-like habitats abundant with essential flowering nourishment. The overall insect populations tripled, surpassing initial expectations. Additionally, these flourishing hubs of pollinators are extending benefits to vegetation in nearby agricultural areas, as evidenced by satellite imaging.

Dr. Lee Walston, an ecologist at Argonne and the lead author of the study, expressed enthusiasm about the scale of positive influence managed solar landscapes can have on insect biodiversity and abundance. The strategic integration of natural ecosystem elements adjacent to renewable projects, as demonstrated in this study, could potentially offer a win-win scenario, supporting the expansion of clean energy infrastructure while addressing the decline in insect populations.

The research underscores the concept of “solar sharing” – a departure from the traditional approach of isolating solar infrastructure from its surroundings. By allowing vegetation to thrive around solar facilities, solar farms help bees, and a new haven is created to support fragile bee colonies. The collapse of global bee populations poses a severe threat to agriculture, as over $500 billion in crop production relies on natural pollination annually.

But it doesn’t have to be only about the bees. Agrovoltaics refers to co-locating agriculture and solar photovoltaic systems on the same land. The solar panels are elevated and spaced out to allow crops to be grown underneath while allowing sunlight to reach the crops. The partial shade created by the solar panels can benefit certain crops by providing shelter, reducing evapotranspiration, and lessening weed pressure. The crops benefit the solar infrastructure by reducing heat under and around the panels.

Some bee-friendly crops and flowers that could thrive under the partial shade of solar panels include potatoes, cabbage, kale, carrots, Brussels sprouts, celery, spinach, onions, garlic, lettuce, arugula, strawberries, asparagus, leeks, swiss chard, parsley, oregano, green beans, sunflowers, cosmos flowers, marigolds, clovers, borage, and many varieties of wildflowers. These provide nutrient-rich pollen and nectar that support diverse bee populations.

These findings open the door to a new perspective on the relationship between solar power and ecological conservation. Instead of erecting barriers, solar infrastructure can be designed to coexist harmoniously with the environment. The success observed in this study suggests that solar farms help bees and can play a crucial role in aiding declining bee populations, offering hope for preserving essential pollinators.

As the world grapples with the urgent need for sustainable practices amid the climate crisis, the authors hope these groundbreaking findings will inspire further research. Exploring habitat-friendly solar blueprints to integrate nature into the urgent climate transition could be a transformative step forward. Dr. Walston emphasized the potential symbiosis between solar power and ecological conservation, envisioning bees flocking to blossoms beneath solar panels, which may reveal surprising pathways to advance sustainable energy and agriculture concurrently.

In conclusion, solar farms help bees. Once seen solely as agents of clean energy, they are now emerging as potential allies in the crucial mission to preserve and protect bee populations. This unexpected synergy between renewable energy infrastructure and environmental conservation opens doors to innovative solutions that could redefine the future of sustainable energy and agriculture.

Australia just broke a major record for new solar panel roof installation

Australia just broke a major record for new solar panel roof installation

Australia, one of the world-leaders in household rooftop solar panel uptake, has once again broken its own record for the number of solar panels installed in a year. In 2020, installations were up nearly 30 percent from the year before, according to an analysis from Australia’s national science agency, CSIRO.

 

The data, compiled by energy efficiency experts and reported in a CSIRO statement, come from Australia’s Clean Energy Regulator, a national body tasked with reducing the country’s carbon emissions and accelerating its use of clean energy.

It shows that while their federal government leaders are lagging behind on climate action, everyday Australians are doubling down on renewable energy, installing more rooftop solar panels than ever before and beefing up the size of their rooftop arrays.

“Sustained low technology costs, increased work from home arrangements and a shift in household spending to home improvements during COVID-19 played a key role in the increase of rooftop solar PV systems under the SRES,” said Clean Energy Regulator senior executive Mark Williamson, referring to a national scheme in Australia that allows homeowners and small businesses to recoup some of the costs of putting the panels on their roofs.

The record-breaking year is really just another one for the books for the sun-soaked country, which has seen installations rise year on year as the cost of renewables has fallen. In 2018, rooftop solar installations jumped almost 60 percent from 2017.

 

“Australia is one of the sunniest places on the planet,” said Michael Ambrose, a senior experimental scientist at CSIRO who led the CSIRO analysis, which mirrors a separate annual assessment of the Australian rooftop solar market from consultancy firm SunWiz.

“We lead the world in PV capacity on a per capita basis at 591 watts per person which is almost eight times the worldwide average,” he said.

Photovoltaics, or PV, is what scientists often call solar panels, which are made of solar cells stacked together to capture the Sun’s energy and turn it into electricity. Capacity is the amount of electricity a solar system can produce at its peak.

“The [latest] solar PV installation data shows how quickly PV systems have been taken up across Australia and the increasing size of the PV arrays,” Ambrose said.

Data used in the CSIRO analysis from Australia’s federal Clean Energy Regulator showed that in 2020, a record-high 362,000 solar panels were installed and certified under the scheme for small-scale renewables.

At the year’s end, Australia had a total of over 2.68 million rooftop solar systems on homes – which means one in four households are now soaking up sunlight and converting it to electricity.

 

And the country’s rooftop solar capacity is only expected to grow, with installations already trending higher in 2021 based on early data.

But amidst the fanfare, there are bigger questions that need tackling: can Australia’s aging electricity network cope with the huge influx of solar energy – it’s old and really needs to be upgraded – and could solar panels coupled with household batteries in fact keep the grid stable and bolster electricity supplies in the event of extreme weather, such as lightning strikes.

“How these systems behave when sitting on our rooftops can have material impacts on the broader electricity grid,” renewable energy researcher Naomi Stringer from UNSW told Renew Economy.

“Impacts of rooftop solar can be particularly acute during disturbance events when the grid is already strained, posing new risks to power system security,” she said.

“However, there are also important opportunities to harness rooftop solar capabilities to help restore power system security.”

That potential is seen by many small Australian communities who faced power outages as they fought fire fronts during the country’s devastating ‘Black Summer’ bushfires and who are taking matters in to their own hands – going off-grid, installing their own standalone solar-powered systems.

When we take a step back though, some researchers say that Australia is playing catch-up to other renewable leaders such as Germany.

Australia might be building new renewable energy infrastructure, including large solar arrays and wind farms, at a per capita rate ten times faster than the global average, in recent years. But it still trails behind other countries in the total amount of energy it generates from renewables.

 

“Denmark is generating about two-thirds of its electricity from renewables – non-hydro renewables – and it has a population a fifth of Australia, so their per capita annual generation is many times that of Australia, and similarly for Scotland,” renewable energy expert Mark Diesendorf from UNSW Sydney told the Australian Associated Press in early 2021.

 

All the while, solar cell scientists have been testing new-fangled configurations with materials other than silicon that can capture more parts of the light spectrum and could be used to build more efficient solar cells – and they’re smashing record after record, too.

Nothing like a bit of healthy competition.
