A Tree Planting Update
I begin this post with an apology. I have posted only sporadically this past year, and the reason is not Covid as one might think. No, it’s simply that writing repeatedly about environmental, social and energy topics over the past several years, it seems like every little bit of progress on any of these fronts is wiped out by news headlines on events in politics, business or the weather. The actions any of us take to combat these developments always seem like too little and too late, so I learned to accept one possibility: that the world as a whole will not wake up to action until the planet is undoubtedly, unequivocally in peril; and then everyone will come together and frantically decide on measures that could have, should have, been taken decades ago. The Covid pandemic is a case in point; and the recent spate of droughts, wildfires and floods in many countries is another.
So here we are finally at a point where the world is waking up and ready to take action. At this juncture I would like to highlight the work of a small community of people working in a small village near the town of Tiruvannamalai in South India who have been working and learning and teaching and playing and planting in exemplary fashion for the past decade and more. Today, instead of writing my own blog, I’ve decided to simply post their tree planting update with photographs. I hope you find their post as inspiring as I did. Read on below:
Dear friends,
Greetings from Tiruvannamalai.Hope you are all doing well. We have been blessed this year to receive lots of rain from June itself and we have been actively involved in this season’s tree planting. We have completed the planting of more than 8000 trees in 7 locations which include 4 Eri bunds and upper slopes, on the hill, in the plains around the hill etc. We will be continuing the work in the weeks to come.
This year’s planting has had a different focus. One of the senior members of our team Shyam, attended an ecology course on native trees in Auroville and came back with a passion for evergreen tree species of the Eastern ghats. We have always planted indigenous trees of this region and over the years our nursery has produced more than 180 native species. While we continue with the same we have brought special focus on the Evergreens.
Here is Shyam’s brief write up on the evergreen patch:
The idea to have an evergreen patch came from most trees on the hill being deciduous and the hill looking quite barren in summer. Plus our recent planting places mostly had some tough evergreens surviving as most deciduous species are heavily grazed by deer leaving them stunted, to grow back to only be stunted again grazing. ( One of the outcomes of our successful afforestation has been the sharp rise in spotted deer population) The evergreen species are fast disappearing as more and more forests are being destroyed, so to find a home to these species was enticing and is very critical for the survival of these species. Many of them are already on the Red list of the IUCN. Obviously the dream is to imagine an evergreen canopy sometime in the future that may be our children will walk around even in summer times. So the idea was to plant tough faster growing evergreens that will eventually provide the conditions for other species usually found in more mature forests to grow in and eventually regenerate. We also tried planting a small number of saplings of species that were non-existent on the hill in an effort to introduce them. These were planted in selected places with good soil and canopy conditions hoping to maximise their survival chances.
Various strategies were tried out to improve their survival chances and to aid faster growth to clear the height the deer can reach, some are 1. Selecting a place with good soil and canopy cover conditions 2. Digging deeper pits and filling them back with a compost + top soil mix which helps with better moisture retention and root penetration 3. Making tree guards for few saplings of newly introduced trees that are prone to grazing 4. Making bunds with rocks from around to help with water percolation, top soil piling up from upper slope 5. Planting in direct/partial sun or even in very shaded spots based on their preferred growing conditions 6. Planting some taller saplings in bigger bags for species that need a tree guard as the bigger root systems will help them grow faster past the grazing height
We have planted around 700 saplings in this section so far. Around 90 saplings belong to species that aren’t found on hill at any stage and around 500 belong to species that preexist on the hill in a sapling stage.
Here are the names of some of the species :
Aglaia elaeagnoidea
Drypetes sepiaria
Diospyros ovalifolia
Drypetes porteri
Diospyros chloroxylon
Chionanthes zeylenica
Chionanthes ramniflorus
Neolitsea scrobiculata

We will end with wishes for a green and healthy planet.
Warm regards,

Opium: The unlikely poster child for renewable energy
On 27 July 2020, Justin Rowlatt, Chief Environmental Correspondent of BBC News, published an article with the headline: What the heroin industry can teach us about solar power.
I missed that, but a month later found it reported in an issue of Zac and Jesse’s amusing and informative blog called “Now You Know.” about issues related to electromobility and renewable energy. This particular episode of the blog was called: Solar Panels: Proof is in the Poppies where they highlighted the findings reported by Justin Rowlatt.
Solar Panels for sale in Afghanistan: stacked three stories high. Image courtesy BBC News
So what’s the story here?
In 2013, the first Afghan farmer used solar panels to power a pump that brought water up to the surface from 100 meters below ground. Prior to that, his only alternative had been diesel pumps. Pumps ran on dirty diesel that fouled his motors and caused frequent breakdowns, in addition to intermittent supply. Running on solar power was clean and free, the pumps worked reliably, and the farmer was able to grow 2 or even 3 crops a year, in addition to increased yields per crop. The following year, a few panels were available for sale in local markets. Since then, the sale of solar panels has taken off in the province, with 67,000 arrays counted in Helmand Valley alone in 2019. The negative effect of this bounty is that opium output has more than doubled in the intervening years.
If only we could see that kind of exponential growth of renewables in rich countries, the world’s environmental outlook would not be the bleak picture it is today. But there is a surprising amount of misinformation in the educated, industrialised world. This is partly due to the existence of powerfully entrenched corporations that jealously guard their own turf and discourage innovation. The second negative factor is the advertising industry that has spent decades fine-tuning their ability to spread the message of their paymasters, however detrimental to the planet. Time to take a leaf from an Afghan farmer’s book on energy, if not for choice of crops.
Reposting from Electrifying: All-Time Highs for Renewables in 2020
As the blog ELECTRIFYING noted this week: Renewable electricity generation has hit all-time highs in the first half of 2020. And this despite the slowdown in utility scale renewables installations as a result of Covid-19. Read more at the link to the original posting below.
Renewables have seen all-time highs in the first half of 2020 |
Post-Covid: We must save the Future, not the Past
When Austrian-born American economist Joseph Schumpeter spoke of creative destruction, he was referring to cycles of innovation in industry as new technologies displaced older, less efficient ones. As a new technology gained the upper hand, older industries died out, giving rise to a period of disruption and major unemployment.
In a chapter in his book Capitalism, Socialism and Democracy, Schumpeter writes: “The same process of industrial mutation—if I may use that biological term—that incessantly revolutionizes the economic structure from within, incessantly destroying the old one, incessantly creating a new one. This process of creative destruction is the essential fact about capitalism,” he said. Schumpeter was more right than he knew, not only about industrial mutation, but in regard to natural mutation. As a passionate environmentalist, I would assert that Schumpeter’s insight is primarily applicable to natural systems. More than 60% of the world’s wealth is embedded in nature and natural systems. Heedless of that, we, in developed industrial societies and all aspiring, developing industrial societies, are recklessly plundering our planet’s natural resources in order to fuel economic growth; in pursuit of the cachet of success, of material wealth far beyond basic human needs of food, clothing and shelter.
Nature’s beauty is free. Raintree blossoms in Schönbrunn Park.
Studies show that most forest trees need to be exposed to fire every 50 to 100 years to invigorate new growth. Epidemiologists have long predicted pandemics like the current one, but societies at large have been too busy chasing prosperity to pay much attention. Now that Nature has targeted humanity with some creative destruction of its own, it’s up to us to learn the lessons of the forest; clearing away the dead wood of outdated industrial practices, investing in lifestyles and technologies that eliminate waste and support planetary health.
What need for annual trillion dollar subsidies for fossil fuels when 99% of scientific studies say we should stop carbon emissions? What need for continued economic growth when wealth accrues to the 1% of the population and leaves the other 99% behind? What need for new technologies when the best ones currently available are not being used widely enough?
Political leaders won’t ask us these questions. We must ask it of them. Our survival as a species depends on it.
Nikola vs. Tesla
Growing up in a country where English was the language of higher education, I inherited an Anglo-centric view of most developments in science and technology. For example, thinking about the history of printing, the names of Johannes Gutenberg and William Caxton came to mind. When I mentioned Caxton to a German friend, they looked blank, having only heard of Gutenberg. Six hundred years before Gutenberg and Caxton, however, there were nameless Chinese monks who used carved wooden blocks coated with ink to print Buddhist texts. Subsequently, movable metal type was used in both China and Korea, two hundred years before Gutenberg’s printing press.
Language matters! The point was driven home to me when I travelled in Central Europe in the 1970s and came across a book. Lightning in his hand: the life story of Nikola Tesla. I read about his discoveries and inventions and thought, it couldn’t possibly be true. Most of these were Edison’s discoveries. The light bulb. The generator. Alternating current. Wrong on all counts apparently. Edison merely perfected the lightbulb and was a savvy marketer. He was also not above using dirty tricks to discredit competition. He is said to have publicly electrocuted dogs and cats with alternating current (ac/which we use today) to prove that his direct current was safer than Tesla’s ac. All this happened in the late 19th and early 20th century. For an amusing take on Nikola Tesla’s many accomplishments compared to Edison’s, see Why Tesla was the greatest Geek who ever lived.
In the 21st century, there’s a face-off between two companies that both borrow the great Serbian genius’s name. Nikola and Tesla. Tesla, as some of you might know, became the most valuable car company on the planet this week, based on market capitalization, overtaking Toyota.

Nikola Motors is far less known, and aims to compete head-to-head with Tesla’s electric semi, a heavy duty battery electric vehicle slated to appear in 2021. Nikola claims its trucks, powered by electricity from a hydrogen fuel cell, will provide driving range comparable to a diesel truck. They say that pure battery electric vehicles (BEVs) will have to compromise either on range or haulage capacity, simply because of the weight of its batteries. Nikola has no sales and no revenue, yet has achieved market valuation of $34 billion in 2020. Hmm! Why is there no end of people willing to bet their money against Tesla?
On the other hand, Tesla has a brilliant track record of achieving seemingly impossible goals, its cars outperforming every other electric vehicle on the road today, and it already has several prototype semis on the road. CEO Elon Musk reiterates at every opportunity that he relies on first principles of physics to base technology choices and manufacturing decisions. The above image, courtesy of the non-profit Transport and Environment (via Clean Technica), seems to support his opinion, that producing hydrogen with current technologies to run vehicles on electricity produced by a fuel cell just does not make economic sense. Many engineers at Toyota, Hyundai, Honda, BMW and Mercedes disagree with Musk and are putting a chunk of their considerable R&D resources into FCEVs* using hydrogen. None of them seem as yet to have prominent plans to roll out extensive hydrogen charging infrastructure so this indicates a future for FCEVs as niche products in the coming two decades.
All the legacy automakers are in a bind because of Tesla’s rapid roll-out of increasingly attractive and popular electric models. They face a triple whammy, locked in to their traditional supply chains, with highly qualified and experienced ICE workforces who need to either be retrained or made redundant, and confronting dramatically decreased car sales in 2020. Post-Covid, the only automotive growth segment seems to be in EVs.
A case can be made for FCEVs in the case of heavy duty, long-range transport vehicles that only need point-to-point charging infrastructure rather than a widely distributed one; think cargo ships, passenger ferries, trains. Aircraft powered by hydrogen? I don’t know whether the concept will take off (pardon the pun), although Zero Avia has short haul aircraft that run on hydrogen fuelled electricity. Whatever the case, the sooner we come off conventional ICEs, the better for our planetary future.

Miyawaki Forests
Anyone who reads the news today, whether on social media, newspapers, television, blogs, or whatever, is confronted with a litany of disastrous news about global warming, climate change, natural disasters, political crises, corruption, conflict and so on. True to the adage that good news is no news, there are few in-depth news stories about far-reaching events, running mostly in the background, that have potential to change the world. To give them credit, most news outlets nowadays are aware of this deficit and pepper their front pages with good news, most of which are one-offs; heart warming stories that are categorized as “human interest” stories. Don’t get me wrong. I love human interest stories, and devour them with my morning coffee. But they are not weighty enough to counter the leadbelly that results from reading the rest of the news. So how to counter that?
A perceptive listener once corrected me when I quoted: knowledge is power. No, they chided. Knowledge is only potential power. You have to do something with your knowledge to make it powerful. If you think about it, the converse holds true for bad news. Too much knowledge can be disempowering and reduce us to abject helplessness unless we do something about it. But what?
In an earlier blog entitled “Three score years and ten” I outlined a series of actions one can take to counter planetary leadbelly, beginning with baby steps. Meanwhile, here’s another link to a website that tells in-depth stories of people taking action around the planet to restore its health. Today, this particular story about Miyawaki Forests caught my eye. Tell your planetary gloom to take the day off. Follow the two links above, read, and enjoy.
Ecosia
The Covid-19 lockdown has put a damper on my scheme to sponsor the planting of at least 1000 trees in 2020. I hoped to plant a few of the thousand with my own hands. I think taking personal action leads to a deeper commitment.
There have been many articles recently about a Swiss company called CLIMEWORKS that has a strategy to remove CO2 from the air through conversion to carbonates. These carbonates can then store carbon underground as solids or else, in gaseous form, be treated to produce synthetic liquid fuels at an ultimate cost of around $ 1 per liter, as mentioned in a recent Nature Briefing newsletter.
Sequestering carbon with trees is much slower, less industrial, and would be Nature’s way to restore the planet. Following Nature’s way might be less glamorous to the uninitiated, but to be done well, it requires a wealth of local knowledge. This local knowledge is often the kind that is not found in text books or taught in schools. The kind of people who possess this knowledge usually do not know they possess something valuable, since much of the world discounts their knowledge for lack of paper qualifications, not even a high school diploma. But some of the most successful development programs have been based on inputs from aboriginals and “primitive” forest tribes. After all, artemisinin, cinchona and willow bark had been in use for centuries before modern medicine discovered them; artemisinin in China 2000 years ago, cinchona in early South American cultures. Willow bark and leaves were used by Assyrians, Sumerians, early Egyptians and ancient Greeks. So let’s plant trees then, as widely as we can, in order to suck up carbon. But if we make use of available local knowledge, we will find dozens, if not hundreds, of ancillary benefits.
One such afforestation program, conducted by a non-profit foundation called The Forest Way, strictly plants only indigenous species of trees on an area that covers a few square miles of once-barren land. In the twelve years since the planting began, a few dried out streams carry water again, leaf litter decomposing on the forest floor is slowly building up a layer of healthy soil and, most spectacular, the number of bird species sightings have increased from around 60 to 230+ at last count.
The subject of tree-planting brings me finally to the title of this post. ECOSIA calls itself an “ecological search engine” and it aims to help reforest the earth. According to Wikipedia, Ecosia plants an average of 1 tree for every 45 searches made on it. The Ecosia search engine works with all browsers and once you begin to use it, the page shows a small window with a tree symbol and a number to denote the searches made on this search engine since the download. Most recently Ecosia’s website reports 97 million trees planted (and counting), and more than 15 million users. Make that 15 million and one. I became an Ecosia user yesterday!
What we need to do now (Book Review)
Chris Goodall (environmentalist, economist and businessman) has published a book in 2020 on recommended steps for a zero carbon future. In 12 concise and easily digestible chapters he outlines steps to be taken to achieve (or even exceed) the UN goal of stopping greenhouse gas emissions by 2050. Although specific to the UK, the straightforward proposals in the book could easily serve as a blueprint for any country around the world, regardless of where they stand on the spectrum of greenhouse gas emissions intensity.
The opening chapters deal with green energy generation to power local and regional grids, then move on to housing and transport. The chapters on transport deal with ground, air and shipping transport, three sectors that might need different fuels, depending on technological developments currently in their early stages; battery electric vehicles (BEVs) for ground transportation, hydrogen used with fuel cells for shipping, and liquid synthetic fuels for aviation. There are potential breakthroughs in the offing for each of these solutions and, of course, unforeseen developments in battery technology could mean that energy density is high enough for BEVs to power ships and airplanes as well as cars, buses and trucks. With so much potential waiting in the wings, this is an exciting time for new technologies, despite the looming threat of runaway climate change that can annihilate patterns of living we’ve developed over the past century.
There is a chapter devoted to fashion and its climate impact, as well as one on the carbon footprint of buildings, specifically in concrete production, and fossil fuels in heavy industry. There are known low-carbon solutions here, and the main problem is changing established production norms, the long lifetimes of existing physical infrastructure, and changing the mindset of the large corporations that own these industries.
Food production and forests have great potential to (one) reduce emissions and (two) absorb more CO2 respectively. Finally, it’s the economist’s turn to ask: how will all these changes be paid for? The straightforward answer is through a carbon tax that captures the environmental cost of the fuels used. However, experience has shown that the implementation of this straightforward answer is anything but. There are powerful vested interests to be overcome, not to mention the expense of retraining workers made redundant by obsolete industries.
Two chapters at the end of the book deal with direct air capture of CO2 and geo-engineering solutions. Each of these have their champions, but in my opinion, direct air capture (by industrial means) would never be cost-effective for a simple reason. The technologies that are sophisticated enough to make direct air capture cost-effective would also be good enough to lower emissions to the point where the technology is no longer needed. A sort of negative Catch-22. As for geo-engineering, the scales and money required for this effort would be best spent on researching and implementing technologies that lower emissions in the first place, rather than trying to decrease their effects. Secondly, there are too many unknowns associated with such large scale engineering projects. History is replete with examples of engineering hubris. The second half of the twentieth century saw countless predictions that “science would solve all problems” and “plentiful nuclear energy will provide power that is too cheap to meter.”
The final chapter, entitled “What can we do ourselves,” is more important than most people realize. On the one hand, individual actions do count and “little drops make an ocean.” But a second, little regarded effect of “little drops” will be the most important. Whether we live in democracies or dictatorships, ultimately, governments are guided by the cumulative wisdom of the governed. And in any nation where the overwhelming majority of its citizens practice sound environmental stewardship, this mindset will be inexorably transferred to the leadership as well.
We all know that leadership counts. We all realize intuitively that we get the leadership we deserve. So ultimately, logic stands on its head and we are forced to admit that we, the people, are the leaders who have to show our leaders the way.

The Hydrogen Economy
The hydrogen economy may be only a decade away, or more. Some people think that battery electric vehicles will replace combustion engines in the interim. Whatever the case, there are exciting new developments happening in the world of hydrogen. Here’s a shared post from the blog Electrifying entitled Hydrogen – unleash the beast.
Corona-tion Times
Thousands of thinking people all over the world are now beginning the see the current corona pandemic as an opportunity to radically restructure the world; to reduce our consumption of resources from a finite planet; to recalibrate a global economic system that enriches the 1% while impoverishing the 99% (and the planet in the bargain), to rethink our agricultural systems, currently dominated by large holdings and industrial corporations, to small farms and tenants who look to enhance biodiversity rather than only being driven by increased yields and profit.
Will humanity choose the road less travelled?
In whichever country in the world we live in right now, the crucial question our governments will deal with in the immediate aftermath of the current crisis will be: which of the following systems will be bailed out first: Banks and the financial system; major food corporations and large producers; the biggest energy utilities; airlines and the transportation system.
From the point of view of the average citizen, all of them are of equal importance. Most important, of course, is access to the most basic needs of life; food, clothing and shelter. In extraordinary times like this, when governments throw fiscal discipline overboard in order to preserve life, the idea of Universal Basic Income (UBI) suddenly looks attractive again. Here’s a link to a Wikipedia article on UBI that shows how the idea was first touted in the early 16th century in Sir Thomas More’s Utopia.
The lockdown continues, and Nature flourishes
Would the UBI plan work? In the best of all possible worlds, it certainly might, considering that the assets of the above-mentioned 1% would cover the costs. Is the UBI plan feasible? Who knows? Or as Shakespeare had Hamlet expressing doubt, “Ay, there’s the rub, for in that sleep of death what dreams may come when we have shuffled off this mortal coil, must give us pause.” On the other hand, a modern philosopher reminds us that a good crisis should never be thrown away. In other words, who knows what solutions may be workable in these extra-ordinary circumstances as we enter a new paradigm of learning, living, and learning to live.
