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.

Coldplay work towards net zero on sustainable tour

Coldplay work towards net zero on sustainable tour

Live concerts and performances generate 405,000 tonnes of greenhouse gas emissions every year, according to the Tyndall Centre for Climate Research.

Founded in the late 90s in London, Coldplay have been touring the world since 2000, and are revolutionizing touring to reduce their negative impact on the environment whilst maintaining positive interactions with fans globally.

Environmentally conscious touring

Their current world tour, Music of the Spheres, utilizes a range of new technology, company and charity partnerships and industry defining developments to combat their environmental influence.

The sustainability initiative is guided by three principles:

  • Reduce — less consumption, more recycling and cut CO2 emissions by 50% (in comparison to the 2016-17 tour)
  • Reinvent —support new green technologies (including kinetic dance floors) and develop new sustainable, super-low carbon touring methods
  • Restore — fund projects and draw down more CO2 than the tour produces

The journey to sustainable touring has been overseen by Green Nation and Hope Solutions.

“Playing live and finding connection with people is ultimately why we exist as a band. At the same time, we’re very conscious that the planet is facing a climate crisis,” say Coldplay.

“So we’ve spent the last two years consulting with environmental experts to make this tour as sustainable as possible, and, just as importantly, to harness the tour’s potential to push things forward. We won’t get everything right, but we’re committed to doing everything we can and sharing what we learn.”

Renewable energy powering the future of live music

A selection of different sustainable energy sources are utilized to power the world tour:

  • Coldplay have partnered with BMW to develop a mobile, rechargeable battery that can power 100% of the show with renewable energy, anywhere in the world. Created using recycled BMW i3 batteries, the battery is the first of its kind.
  • Fan power in the form of kinetic dancefloors and static bicycles is being harnessed. Energy Floors have created tiles especially for the tour that are durable, portable, and use the audience dancing power to charge the batteries running the show.
  • Sustainable biofuels for vehicles, solar photovoltaic panels to charge the batteries and where necessary make up the rest of the renewable, low-emission energy used to power the show and tour.

SAF: Providing sustainable flight options 

“Although the tour has been carefully routed and pre-planned to minimize air travel, some flying is unavoidable,” Coldplay’s sustainability pledge reads.

“For all flights, commercial and charter, we pay a surcharge to use or supply Sustainable Aviation Fuel (SAF).”

The fuel is created from waste including used cooking oil, and can help reduce greenhouse gas emissions from air travel by up to 80%.

Audience commitment to net-zero goal

Audience members are given reusable LED wristbands as part of the show. The bands are made from 100% compostable materials, and wristband production has been reduced 80% through collecting, sterilizing and recharging them after use.

Coldplay have collaborated with One Tree Planted to plant one tree for every ticket sold to the Music of the Spheres world tour, reducing the impact of the crowds.

The tour is also working with the non-profit organization Kulture City to make the tour inclusive for audience members with sensory issues through providing sensory bags and access to a mobile sensory room.

Partnering with SAP to reduce audience travel impact 

33% of the 405,000 tonnes of greenhouse gas emissions generated by live concerts each year is from audience travel.

Coldplay are combating this through a free app, developed in partnership with software development company SAP. The app, which has had over 350,000 downloads since its launch in March 2022, encourages fans to use low carbon transport options and offers rewards through discount codes.

“With our technology and solutions, we empower organizations worldwide to drive sustainable change,” says Christian Klein, CEO of SAP.  “Coldplay and SAP share a common and profound commitment to sustainability, and we are thrilled to join forces to make their tour as environmentally friendly as possible.”

Coldplay’s sustainability goals — mid-tour review

The band have recently issued a statement regarding their sustainability goals so far through their tour, as reviewed by MIT’s Environmental Solutions Initiative.

“On a show-by-show comparison, the Music Of The Spheres Tour has so far produced 47% less CO2e emissions than our last stadium tour (2016-17),” the statement reads.

The update lists achievements so far, but is also realistic that it hasn’t hit its 50% target, and that there is still room to grow and improve.

What is the future for Coldplay’s sustainability initiatives? 

There seems to be no end in sight for the lengths that Coldplay will go to in an effort to reduce their environmental impact.

Alongside their direct actions, 10% of their income from all avenues going to the Good Causes Fund, supporting charities including:

  • The Ocean Cleanup
  • ClientEarth
  • One Tree Planted
  • Global Citizen

Whether you’re a fan of their music or not, it’s hard to deny that Coldplay are pioneers for the future of sustainability in live music.

 

 


Floating solar: a small but vital role for India’s sunrise sector

Floating solar: a small but vital role for India’s sunrise sector

India’s G20 presidency next year offers a “golden opportunity” to accelerate the deployment of renewable energies, environment minister Bhupender Yadav told reporters on April 26 in a meeting with the International Renewable Energy Agency (IRENA). This year is a litmus test for progress, representing a deadline for India’s renewable energy target of 175 gigawatts.

While floating solar photovoltaic (FSPV) was not originally envisaged as part of the mix, which only included terrestrial and rooftop solar, it has emerged as a small but not insignificant catalyst for the figures.

Despite later including large hydropower in the renewable category to help meet the target of 175 GW, which originally included only small hydropower, India is still set to miss the goal, with 156.6 GW of utility-scale renewables as of March 2022, plus an estimated 11 GW of rooftop solar.

The shortfall, due mostly to the slow development of rooftop solar, highlights the need to further diversify India’s portfolio of green energy sources.

An alternative to terrestrial solar

India’s journey with floating solar began in 2014 when it was approved by the Ministry of New and Renewable Energy (MNRE), in Kolkata. S P Gon Chaudhuri, a veteran of the country’s renewable energy sector, told The Third Pole: “The organisation tasked with implementing this project was NBIRT [the NB Institute for Rural Technology], of which I was chairman at the time.”

 

When we start looking for a piece of land, it isn’t easy. In places with a lot of land, there are too many projects and hence, transmission is a challenge. Floating solar addresses so many problems

Manu Srivastava, commissioner for new and renewable energy, Madhya Pradesh

 

Once the project was completed, “officials from organisations such as the World Bank visited the site and examined how a floating solar plant is set up, how it works”, Chaudhuri recalls. “Basically, it was a study centre.”

Plants in Punjab, Kerala, Gujarat and Tamil Nadu followed, among others. India’s reservoirs cover 18,000 square kilometres with the potential to support 280 GW of floating solar, according to a report by think tank The Energy and Resources Institute (TERI).

High costs and design challenges are still holding back the deployment of the new technology, which as of November 2021 had an estimated cumulative installed capacity of just 2.7 megawatts, making it little more than a pilot project.

However, according to the think tank Council on Energy, Environment and Water (CEEW), India now has about 170 MW of operational floating solar capacity and another 1.8 GW under different stages of development. The steep increase, a CEEW spokesperson explained, is due to the fact that the first plants deployed were small, and India has only started implementing large-scale floating solar in recent years.

Terrestrial solar PV is land-intensive, and the TERI report recommends exploring alternatives such as floating solar to keep pace with India’s national target of 100 GW of additional solar capacity by the end of 2030. The state of Maharashtra, the authors say, has the most potential and could generate 57.9 GW on 3,173 sq km of its reservoirs’ surfaces.

“The FSPV addition is small in relation to the entire market for solar energy, but it could be a viable alternative for speeding up solar power deployment in India,” a 2021 study by researchers at Effat University in Saudi Arabia stated.

 

Floating solar milestones

Recent developments in the floating solar space hint at the sector’s promise. In August last year, government-owned NTPC, India’s largest integrated energy company, commissioned a 25 MW project on the reservoir of its Simhadri thermal power station, in the state of Andhra Pradesh.

The plant has the potential to generate electricity from over 100,000 solar PV modules, which could light around 7,000 households and avoid the emission of at least 46,000 tons of carbon dioxide every year over its lifespan.

In January 2022, the state-owned hydropower corporation NHPC signed a deal with a developer in the eastern state of Odisha to build a 500 MW floating solar plant. It will initially invest over INR 20 billion (USD 261 million) in 300 MW-worth of floating solar projects. The project will help the state to meet its renewable energy generation targets, besides creating investment and employment opportunities.

On March 10, 2022, Tamil Nadu’s chief minister MK Stalin inaugurated India’s largest floating solar power plant, which was constructed at a cost of INR 1.5 billion (USD 19.6 million).

 

Scarce land, more water

Most Indian states lack land, but have enough water for FSPV. Installing solar on water can increase the panels’ efficiency due to lower temperatures that prevent overheating, Chaudhuri explained.

Manu Srivastava, commissioner for new and renewable energy with the government of Madhya Pradesh, said: “When we start looking for a piece of land, it isn’t easy. In places with a lot of land, there are too many projects and hence, transmission is a challenge… Floating solar addresses so many problems.”

Avnish Shukla is executive engineer at Rewa Ultra Mega Solar Ltd, a joint venture that has commissioned solar projects in Madhya Pradesh. Shukla told The Third Pole that a 600 MW floating solar plant in the state of Madhya Pradesh will be commissioned by August 2023, likely to be one of the largest in the world.

Shukla said that solar projects often occupy barren land, not used by agriculture, industry or people. “Since there is scarcity of such a type of land, we face trouble… In such a scenario, water bodies are perfect. Moreover, water will evaporate if we do not use it to install solar panels [to reflect the sun’s rays].”

Vinay Rustagi, the managing director of Bridge to India, a renewable energy consultancy, pointed out that some floating solar sites that are located near hydropower projects or in thermal plant reservoirs already have ready access to their transmission infrastructure.

 

Falling costs

Ground-based installations still form 93.1 per cent of India’s grid-connected solar PV, according to a 2020 report by TERI. Utility-scale solar costs fell 84 per cent between 2010 and 2018, making large-scale solar cheaper in India than anywhere else.

According to Chaudhuri, the cost of setting up a floating solar plant is currently INR 50-60 million (USD650,000-780,000) per MW, while conventional land-based solar projects cost the equivalent of USD 520,000 per MW, a difference that explains the slow take-off of the technology. However, he said, floaters and maintenance are becoming more cost-effective.

“India needs to meet certain targets it has committed to by 2030, which means states need to adopt more such [floating solar] plants, as they do not have so much land to spare,” he said.

According to Srivastava, transporting the lightweight but big floaters the panels sit on can be a challenge. However, these are low-tech components, so manufacturing plants installed near the development site could bring costs down further.

Floating solar projects do require longer due to the need for more detailed assessments of sites’ hydrography and water-bed topography. Furthermore, both the capital and operating costs are slightly higher due to the more complex design and risks of working in water, Srivastava added.

Rustagi, however, said the local governments and municipal agencies in charge of most inland water bodies must push for them.

Binit Das, deputy renewable energy programme manager at New Delhi think tank the Centre for Science and Environment, agreed but said there are other, more technical hurdles to overcome: “The solar floating system needs to hold solar panels on the water for over 25 years, so the racking system needs to be highly resistant to corrosion, must have a long lifespan and high load capacity.”

He added: “Since this is a relatively new solar power technology, it requires specialised solar power equipment and more niche solar panel installation knowledge.”
