Difficult to imagine that with all the times India has appeared in these pages, and separately all the times that solar has appeared, this is the first time they appear together:

India’s Quest to Build the World’s Largest Solar Farms

Pavagada Ultra Mega Solar Park, a clean-power plant the size of Manhattan, could be a model for the world—or a cautionary tale.

Ashok Narayanappa drives a bullock cart carrying hay, along a stretch of road lined with pylons, in Pavagada Solar Park.

Every morning in the Tumakuru District of Karnataka, a state in southern India, the sun tips over the horizon and lights up the green-and-brown hills of the Eastern Ghats. Its rays fall across the grasslands that surround them and the occasional sleepy village; the sky changes color from sherbet-orange to powdery blue. Eventually, the sunlight reaches a sea of glass and silicon known as Pavagada Ultra Mega Solar Park. Here, within millions of photovoltaic panels, lined up in rows and columns like an army at attention, electrons vibrate with energy. The panels cover thirteen thousand acres, or about twenty square miles—only slightly smaller than the area of Manhattan. Continue reading

Neighborly Advice

Thanks to the team at Yale Climate Connections:

When do many people decide to go solar? When they’re referred by a friend or neighbor.

They’re more likely to listen to people they trust.

Rooftop solar panels can save people money on their electricity bills. And those savings can mean a lot — especially for people with low incomes, who might have to choose between paying for utilities or buying food or medicine…

 

Africa’s Sunlight & Europe’s Electricity

Fred Pearce brings us news from the European-African axis of renewable energy:

In Scramble for Clean Energy, Europe Is Turning to North Africa

In its quest for green energy, Europe is looking to North Africa, where vast solar and wind farms are proliferating and plans call for submarine cables that will carry electricity as far as Britain. But this rush for clean power is raising serious environmental concerns.

Solar panels in sun-rich North Africa generate up to three times more energy than in Europe. And North Africa has a lot more room for them than densely populated Europe. Continue reading

America’s Climate Bill Looks Even Better Than Before

Late last month, analysts at the investment bank Credit Suisse published a research note about America’s new climate law that went nearly unnoticed. The Inflation Reduction Act, the bank argued, is even more important than has been recognized so far: The IRA will “will have a profound effect across industries in the next decade and beyond” and could ultimately shape the direction of the American economy, the bank said.

We do not have time for the patience required for proving the futility of resistance, but this historical perspective is valuable nonetheless:

When Coal First Arrived, Americans Said ‘No Thanks’

Back in the 19th century, coal was the nation’s newfangled fuel source—and it faced the same resistance as wind and solar today

More Energy on Less Land: The Drive to Shrink Solar’s Footprint

With the push for renewables leading to land-use conflicts, building highly efficient utility-scale solar farms on ever-smaller tracts of land has become a top priority. New approaches range from installing PV arrays that take up less space to growing crops between rows of panels.

From the ground, the new solar farm shimmers like a mirage oasis on a hot summer day. Instead of row after slanting row of shiny panels stretching taller than corn, this array, mounted directly on the earth, lies flat as water. Continue reading

Agrivoltaics Advancing

The concept of agrivoltaics has been an occasional topic in our pages over the years, most recently as we have prepared to plant thousands of coffee saplings. Ellen Rosen focuses our attention on how the advances in technology, and entrepreneurship in this space, are addressing the challenges:

Can Dual-Use Solar Panels Provide Power and Share Space With Crops?

Companies like BlueWave are betting on it. But the technology has its critics.

In its 150-year history, Paul Knowlton’s farm in Grafton, Mass., has produced vegetables, dairy products and, most recently, hay. The evolution of the farm’s use turned on changing markets and a variable climate. Recently, however, Mr. Knowlton added a new type of cash crop: solar power. Continue reading

More Solar Canopy Initiatives

Using solar panels to create shade for coffee trees requires thought about the tradeoffs between the non-shade benefits trees otherwise provide: (nitrogen-fixing in the case of poro trees, plus bird habitat and other biodiversity benefits) and the non-shade benefits that solar panels provide (renewable energy). Solar panels on parking lots and other roofs, on the other hand, seems the definition of a no-brainer. Our thanks to Richard Conniff and Yale e360, as always:

Why Putting Solar Canopies on Parking Lots Is a Smart Green Move

Solar farms are proliferating on undeveloped land, often harming ecosystems. But placing solar canopies on large parking lots offers a host of advantages — making use of land that is already cleared, producing electricity close to those who need it, and even shading cars.

A solar parking facility at Rutgers University in Piscataway, New Jersey, with an output of 8 megawatts of electricity.

Fly into Orlando, Florida, and you may notice a 22-acre solar power array in the shape of Mickey Mouse’s head in a field just west of Disney World. Nearby, Disney also has a 270-acre solar farm of conventional design on former orchard and forest land. Park your car in any of Disney’s 32,000 parking spaces, on the other hand, and you won’t see a canopy overhead generating solar power (or providing shade) — not even if you snag one of the preferred spaces for which visitors pay up to $50 a day.

A New Canopy Concept

When the poro and other trees we planted in the last two years mature, they will provide shade for a thousand or so coffee saplings. High elevation arabica coffee likes shade, and birds like the habitat. Those trees are growing fast, but it will be decades until their full shade potential is reached. As I read “This Colorado ‘solar garden’ is literally a farm under solar panels” I can picture an interesting complement to the shade poro provides:

When Byron Kominek returned home after the Peace Corps and later working as a diplomat in Africa, his family’s 24-acre farm near Boulder, Colo., was struggling to turn a profit.

“Our farm has mainly been hay producing for fifty years,” Kominek said, on a recent chilly morning, the sun illuminating a dusting of snow on the foothills to his West. “This is a big change on one of our three pastures.”

That big change is certainly an eye opener: 3,200 solar panels mounted on posts eight feet high above what used to be an alfalfa field on this patch of rolling farmland at the doorstep of the Rocky Mountains. Continue reading
