Waste colonialism

September 24, 2025 By EarthWise 1 Comment

Plastic pollution is a pervasive environmental problem that manifests itself in multiple ways.  Very little plastic is recycled; most of it ends up in landfills or is burned, both solutions having serious shortcomings.  High-income countries – such as many in Europe, the United States, Japan, and Australia – facing increasingly strict regulations in disposing of waste, have long grappled with the problem.

One approach they have often pursued for dealing with plastic waste is to export the waste elsewhere, preferably to countries with weaker waste regulations.  For over 20 years, China was the place to send plastic waste.  In the 1980s-90s, China accepted trash from richer countries to salvage raw materials from it.  This led to serious pollution, health risks, and illegal dumping.  In 2018, China banned the import of plastic waste.

Since then, Western countries have sent their waste to other parts of Asia and Africa. These waste exports are often advertised as contributions to recycling, but mostly, it is just a charade that simply makes the waste someone else’s problem – namely less developed countries, often with inadequate waste management infrastructure. 

This practice of developed nations consuming excessively and exporting their waste to less developed countries is known as waste colonialism.  It is a modern incarnation of historical colonialism, where natural resources and labor were stripped from colonized regions. 

Its inherent injustice aside, the practice does not solve any of the problems created by waste.  It just moves them somewhere else.

Abandoned farmland and the environment

September 4, 2025 By EarthWise Leave a Comment

Abandoned farmland has been increasing dramatically in recent decades.  Estimates are that a billion acres – an area half the size of Australia – have been relinquished from cultivation globally.  While more and more of the tropics have been cultivated in recent times, the global amount of land used for agriculture has been in decline since 2001.  In the past 30 years, arable land in the United States has declined by almost a sixth.  The situation in Europe is similar.  Huge amounts of the former Soviet Union now lie abandoned. 

Farmland is abandoned for various reasons.  It may suffer from damaged soil so that crop yields are too low to be worth the effort.  Farm owners may become too old or be physically unable to continue farming.  Many younger people head for jobs in the cities and more attractive opportunities.  Wars, natural and man-made disasters, and political turmoil have all contributed.

Another form of largely ignored lands are so-called degraded forests.  These are forests that were logged in the past but are no longer productive and aren’t protected either.  These places also represent unused land with great potential value.

Ecologists point to the potential of these lands as neglected resources for rewilding efforts, improving biodiversity, and for increasing natural ways to capture carbon.  Left to its own devices, nature will usually reclaim abandoned places.  This generally provides benefits for biodiversity and climate.  But mapping, studying, managing, and protecting the increasingly vast tracts of abandoned land could increase their potential to contribute to climate change mitigation and the restoration of species and their habitats.

The demise of American offshore wind

August 18, 2025 By EarthWise Leave a Comment

The demise of offshore wind power in the United States

Europe has 37 gigawatts of offshore wind capacity. China is catching up rapidly.  Across the globe, offshore wind is an increasingly important source of clean, renewable power.  The United States had previously set ambitious goals to join the international effort.  But in the aftermath of the 2024 election, offshore wind in the US is basically dead in the water, pun intended.

The Bureau of Ocean Energy Management announced at the end of July that it is rescinding all designated Wind Energy Areas on the U.S. Outer Continental Shelf, effectively ending all offshore wind development across the Gulf of Mexico, the Gulf of Maine, the New York Bight, California, Oregon, and the Central Atlantic.  Additional policy measures announced by the Department of the Interior ended special treatment for what it called “unreliable energy sources, such as wind.” 

The two significant offshore wind projects underway in the US are both under serious attack by the administration and by newly emboldened special interests.  Vineyard Wind in Massachusetts, with 17 turbines already in operation, is under assault by tourist town forces and fishing groups.  Empire Wind, in New York, which resumed construction after efforts by Governor Kathy Hochul, is under pressure by various special interest groups that are urging President Trump to halt the project.

The current administration has very public and very pronounced antipathy towards wind power in general and towards offshore wind in particular.  And this has brought to a rapid halt billions of dollars in investments and will eliminate tens of thousands of jobs.

Solar power in Europe

July 31, 2025 By EarthWise Leave a Comment

Solar power in Europe is booming

In June, solar power was the largest source of electricity in the European Union for the first time.  Solar supplied a record 22% of the power for the 27-country bloc.  At least 13 of the countries produced new monthly highs for solar power in June.  The Netherlands got more than 40% of its electricity from solar power and Greece 35%.  Other countries with record solar generation included France, Germany, and Sweden.

These solar records are for the most part a result of continuing installations of solar power in recent years as well as long stretches of hot and sunny weather.

Across the EU, nuclear power was the second largest source of electricity, followed by wind, natural gas, and hydropower.  Coal generated only 6% of the EU’s electricity, a new monthly low.  In fact, 15 countries in the EU don’t use any coal to generate electricity at all, including Austria, Belgium, and Ireland, which shut down its last coal plant in June.  All fossil fuels combined generated less than 24% of EU electricity in June, just a little more than the record low of 22.9% set in May, 2024.  Natural gas generation was somewhat higher than last year because of lower levels of hydro and wind generation.

Europe has been grappling with brutal heatwaves with triple-digit temperatures in multiple countries.  The heatwaves were, of course, accompanied by plentiful sunshine, which at least provided abundant solar power at midday, when there was the greatest demand for air conditioning.  This helped to take some of the pressure off the grid and helped to prevent blackouts.

The world is warming and it’s happening faster

July 29, 2025 By EarthWise Leave a Comment

This summer has already seen unprecedented heat in many places.  It started with a record-breaking heat dome in June in the United States.  Alaska had its first-ever heat advisory that month.  Europe has seen triple-digit temperatures in cities like Paris, Madrid, and Rome and even in places like Austria, Sarjevo, Bulgaria, Croatia, and Serbia.  On June 28th, a temperature of 96.8 degrees was measured in Biasca, Switzerland.

According to the latest report by the Intergovernmental Panel on Climate Change, the world is getting hotter, faster.  Human-caused global warming is now increasing by 0.27 degrees Celsius per decade.  That rate was recorded at 0.2 degrees in the 1970s and has been increasing ever since.

Climate scientists have long predicted that the rate of warming in the atmosphere would speed up, which has been evident from measurements for quite a while.  But now, these trends that have mostly been seen in charts and graphs are playing a growing role in people’s lives.

Each increase in the global mean temperature brings about a relatively larger increase in atmospheric extremes that include powerful downpours and severe droughts and wildfires.  According to climate models, extreme rainfall intensifies by 7% with each degree Celsius of atmospheric warming.  But recent data indicates that such record-shattering events are increasing at double that rate.

The current US administration may not accept the reality of the changing climate, but the planet really doesn’t care what it believes.

Raccoons in Europe

July 25, 2025 By EarthWise Leave a Comment

Raccoons are popular and prevalent in Europe

Tens of thousands of raccoons live in Kassel, a city of 200,000 people in central Germany known for its art scene.  Overall, there are an estimated 1.5 million raccoons in Germany.  The omnivorous mammals are native to North America, but they were brought to Germany in the 1930s for fur farming.  Fur farming ultimately ceased but escaping animals and intentional releases ultimately led to a large wild population of raccoons in the years afterward.

Raccoons have gradually made their way across Europe with animals spotted in France, Denmark, Poland, Italy, Austria, and elsewhere.

The people of Kassel have embraced raccoons.  In fact, the place is often called the raccoon city.  Several sports teams are named after the animals.  Many people feed them, and they are pretty much everywhere.  On the other hand, residents have to lock up their trash receptacles and they have to check under their cars before driving places.

Since 2016, the EU has classified racoons as an invasive species because of the threat they pose to native wildlife.  There are no equivalent species like them in Europe.  So, they are a threat to ground-nesting birds, bats in caves, amphibians, and more.  They are able to eat almost anything. 

What to do about raccoons in Europe is unclear.  Despite their popularity in Germany, 200,000 raccoons were culled last year.  But raccoon supporters argue that minks, which are native to Europe, and especially cats, are responsible for much of the pressure on species racoons are accused of consuming.  Meanwhile, Kassel citizens continue to enjoy their raccoons.

Nature: An important climate ally

June 10, 2025 By EarthWise Leave a Comment

Nature is often seen as a victim of climate change, but it’s also one of the most powerful tools we have to fight it. Natural ecosystems, such as forests, wetlands, grasslands, oceans, and soils, absorb and store massive amounts of carbon dioxide. These ecosystems not only help reduce the concentration of greenhouse gases in the atmosphere, but they also regulate temperatures and provide buffers against extreme weather.

One of the most effective strategies for mitigating climate change is simply protecting and restoring these natural areas. For example, mangrove forests – those coastal wetlands filled with tangled, salt-tolerant trees – sequester carbon at high rates and help protect coastal communities from storm surges and rising seas.  Peatlands – another type of wetland – store more carbon than all the world’s forests combined – despite only covering 3% of Earth’s land surface.  Global restoration efforts are underway, from replanting mangroves in Southeast Asia to rewetting degraded peatlands in Europe.

Creating urban green spaces like parks and community gardens, restoring forests through native tree plantings, and adopting sustainable agricultural practices like cover cropping and agroforestry are all proven to be low-cost, high-impact climate solutions. 

While nature-based solutions are gaining recognition, they remain critically underfunded, according to a recent United Nations report.  Closing this gap is essential to unlocking nature’s  full climate potential.

Investing in nature isn’t just about preserving Earth’s natural beauty.  It’s a practical strategy for building a more resilient and sustainable future.

Airplanes and climate change

May 26, 2025 By EarthWise Leave a Comment

Climate change poses all sorts of issues for the aviation industry

The aviation industry is a powerful force in the global economy.  In fact, according to some estimates, the industry transports the equivalent of nearly half the world’s population every year.  But the world’s airports were largely designed for an older era – a cooler one.

As air warms, it becomes less dense, which makes it harder for airplanes to generate lift, which is the force that enables them to fly.

According to a new study by scientists from the University of Reading in the U.K., rising temperatures due to climate change may force aircraft at some airports to reduce passenger numbers in the coming decades.

The research team examined how warmer air affects aircraft performance during takeoff at 30 sites across Europe.  The study, which was recently published in the journal Aerospace, focused on the Airbus A320, which is a common aircraft used for short and medium-distance flights across Europe.

By the 2060s, the research team found that some airports with shorter runways may need to reduce their maximum take-off weight by the equivalent of approximately 10 passengers per flight during summer months.

Of the sites included in the study, Chios in Greece, Pantelleria and Rome Ciampino in Italy, and San Sebastian in Spain will be the four most affected popular tourist destinations.

Climate change is also making air travel increasingly turbulent, and the aviation industry itself remains a growing contributor to global greenhouse gas emissions. 

Taking meaningful action to curb greenhouse gas emissions, including those from the aviation industry, is one of the most crucial ways to mitigate global climate change.

Vegetation and climate change

May 20, 2025 By EarthWise Leave a Comment

More urban vegetation could prevent many heat-related deaths around the world

Temperatures have been steadily rising around the world as a result of the increased greenhouse gas emissions from human activities.  This warming trend has led to more frequent and intense heat waves, droughts, and other extreme weather events.  Rising temperatures are also impacting human health, leading to increased risks of heat-related illnesses and a higher number of fatalities during extreme heat events.

One simple but effective way to reduce the health risks from extreme heat is to increase urban vegetation.  According to new research led by scientists from Monash University in Australia, increasing urban vegetation by 30% could save more than one-third of all heat-related deaths.  The study, which was recently published in The Lancet Planetary Health, examined more than 11,000 urban areas and found that increasing greenery could have saved up to 1.16 million lives worldwide between 2000 and 2019.

The impact of increasing urban vegetation on heat-related deaths varies by climate, greenness, socioeconomic, and demographic factors, with the greatest benefits seen in Southern Asia, Eastern Europe, and Eastern Asia. 

Vegetation has a cooling effect on temperature.  Vegetation helps regulate the Earth’s climate by absorbing carbon dioxide during photosynthesis, which helps to reduce greenhouse gases in the atmosphere. Vegetation also cools the environment through shading, moisture release, and evapotranspiration, which reduces temperatures and mitigates heat-related health risks.

Incorporating more vegetation into urban areas is a powerful solution to mitigate the impacts of climate change and protect human health.

Tigers in India

March 17, 2025 By EarthWise Leave a Comment

The Anthropocene is the term that describes the current era in Earth’s history when human activities are having a significant impact on the planet.  It is an epoch filled with species extinction and species attrition in both numbers and range.  The population of large carnivores are among the most affected species and recovering these animals that play important roles in ecosystems is a formidable challenge.

Tigers in Asia are a prime example of extirpation – removal of a species from a specific area.  They have been eliminated in more than 90% of their historic Asian range over the past century.  A new study, published in Science has found that tigers in India are making a comeback.

India’s National Tiger Conservation Authority estimates that between 2010 and 2022, India’s tiger population grew from 1,706 to 3,682.  Tigers are thriving not only on protected lands but also near some human communities.

Tigers are gone from poorer areas where poaching was prevalent and from areas affected by the violent conflict associated with India’s Maoist rebellion.  On the other hand, the big cats can be found near some prosperous communities where poaching is rare.  Farmers keep cattle in enclosures to protect them from tigers.  

The success in protecting tigers in India could provide some insights for Europe where wolves are making a comeback, and perhaps even in the American West where the resurgence of wolf populations is triggering a violent backlash.

Large predators can survive in the modern world with creative thinking and willingness to find a balance between protection and coexistence.

Planting trees in Europe

January 7, 2025 By EarthWise Leave a Comment

Planting lots of trees is one of many strategies being pursued to combat climate change.  Trees are storehouses of carbon from the atmosphere and planting more of them helps remove carbon dioxide.  But trees do more than that.  Trees are natural air conditioners in cities.

Trees significantly cool urban environments by providing shade and via a process called evapotranspiration by which they release water vapor into the air, which provides cooling.  This helps mitigate the urban heat island effect. Areas under trees in cities can be as much as 25 degrees cooler than in unshaded areas covered in asphalt.

The city of Paris has laid out a plan to help the city prepare for increasing amounts of extreme heat.  The goal is to replace 60,000 parking spaces across the city with trees by the end of this decade.  The plan to rip up parking spaces is part of a greater aim to create more than 700 acres of green space by 2030.  The Paris plan also includes creating more car-free zones and installing reflective roofs on 1,000 public buildings.  Nearly 80% of the buildings in Paris have zinc roofs – an affordable, corrosion-resistant and pretty much inflammable innovation of the 19th century.  However, these roofs can heat up to 194 degrees on a summer day, transferring heat into largely uninsulated top-floor garrets below.

Elsewhere in Europe, Danish lawmakers have agreed on a plan to rewild 10% of the country’s farmland and plant one billion trees.   According to the Danish government, this plan would bring about the biggest change to the Danish landscape in over 100 years.

October was another hot month

December 3, 2024 By EarthWise Leave a Comment

October was another hot month, a continuation of the warming trend

In a year filled with unusually warm months, October 2024 ranked as the second-warmest October in the 175 years of the National Oceanic and Atmospheric Administration’s records.  It was just 0.09 degrees Fahrenheit cooler than the previous global record set just last year.

In our part of the world, North America had its warmest October on record.

Year-to-date, the global surface temperature has been 2.3 degrees Fahrenheit above the 20th century average, which is the warmest such period on record.  This record warmth was observed in Africa, Europe, North America, Oceania, and South America.  With only a little of the year to go, predictions are that there is a greater than 99% chance that 2024 will rank as the world’s warmest year on record.

Other aspects of the warming climate were also in full evidence in October.  Global sea ice coverage was the smallest in the 46 years that it has been tracked, about 1.25 million square miles below the 1991-2020 average.  Ice extent in the Arctic was the fourth lowest on record and ice extent in the Antarctic was the second lowest on record.

Global ocean surface temperature was the second warmest for October and is the warmest ever for the period January to October.

The Atlantic basin saw five tropical cyclones during October, including the deadly and destructive Hurricane Milton that made landfall just south of Tampa Bay. 

The monthly climate postings by NOAA continue to report record-breaking temperatures and significant climate anomalies and events.  This pattern is not likely to do anything but continue in the future.

And the heat goes on

October 16, 2024 By EarthWise Leave a Comment

August 2024 was the hottest August in the 175-years for which there are global records.  The last full month of summer also wrapped up the Northern Hemisphere‘s warmest summer on record.

The average global surface temperature in August was 62.39 degrees Fahrenheit, which is 2.29 degrees above the 20th century August average.  Furthermore, August was the 15th consecutive month of record-high global temperatures, which is a record in and of itself.

Regionally, Europe and Oceana had their warmest August on record.  Asia had its second-warmest August, and Africa and North America had their third-warmest August.

The summer in the Northern Hemisphere was a record-breaker with a temperature 2.74 degrees Fahrenheit above average.  Thinking about climate goals, this is 1.52 degrees Celsius above average, which is a troubling amount.  Meanwhile, in the Southern Hemisphere, where it was winter in the June-to-August period, it was also the warmest ever with a temperature 1.73 degrees Fahrenheit above average.

Globally, this year to date ranks as the warmest ever recorded with a temperature 2.3 degrees above the 20th-century average.  With a few months to go, the prediction is that there is a 97% chance that 2024 will rank as the world’s warmest year on record.

Other aspects of the global climate system were consistent with these record-breaking temperatures.  The global ocean surface temperature for June through August was the warmest on record. 

These monthly climate reports have an unfortunate similarity:  the heat goes on.

Increasing plastic recycling

August 15, 2024 By EarthWise Leave a Comment

How to increase the rate of plastics recycling

Recycling plastic is a complicated matter.  There are many different types of plastic and knowing which things are made of which type isn’t easy.  There are increasingly widespread recycling systems across the U.S., but the actual rates of recycling have been described as “abysmal”.

The plastic commonly used in beverage bottles is polyethylene terephthalate, or PET.  The present nationwide rate of recycling PET is about 24% and has been about at that level for a decade.

A new study by MIT has found that with a nationwide bottle deposit program, the rates could increase to 82%.  At that level, nearly two-thirds of all PET bottles could be recycled into new bottles at a net cost of just a penny a bottle.

The study looked at PET bottle collection and recycling rates in different states as well as other nations with and without bottle deposit policies, and with and without curbside recycling programs.  The study is the first to look in detail at the interplay between public policies and the detailed end-to-end aspects of the packaging, production and recycling market.

Recycling of PET is highly successful in terms of quality.  New products made from all-recycled material is virtually indistinguishable from virgin material.  The crucial bottleneck is the collection of sufficient amounts of material to meet the needs of processing plants.  So, the conclusion of the study is that with the right policies in place, significant improvements can be made.  Several European countries manage to collect more than 90% of PET bottles for recycling.  So, it can be done.

Clean energy investment at record levels

July 26, 2024 By EarthWise Leave a Comment

According to a new study by the International Energy Agency, global clean energy investment will be nearly twice that of fossil fuels this year.  The surging funding for clean energy is being driven by a combination of lower costs for renewable energy and by improving supply chains.

In 2024, the world’s investments in energy are expected to surpass $3 trillion dollars for the first time.  About $2 trillion of that will be directed at green technologies that include renewable power sources, grids, and energy storage; electric vehicles; low-emission fuels; nuclear power; and heat pumps and efficiency improvements.  The remaining amount of just over $1 trillion will fund oil, gas, and oil projects.

The record growth in clean energy investments is taking place in spite of challenging economic conditions related to high interest rates, which demonstrates the momentum behind the global energy transition.

The IEA report does caution that there are big imbalances and shortages in energy investment in various places around the world.  For example, there is a low amount of green energy spending in developing and emerging economies outside of China.  Countries like Brazil and India are leading the way for this sector by having investments in excess of $300 billion.

More money is currently going into solar power development than all other electricity generation technologies combined.  In 2024, solar photovoltaic power investment is set to grow to $500 billion as the falling price of solar modules spurs new investments.

The largest renewable investments will come from China at $675 billion, followed by Europe and the U.S. at $370 billion and $315 billion, respectively.

Potential for floating solar

July 16, 2024 By EarthWise Leave a Comment

As installations of utility-scale solar power continue to expand around the world, there is the issue of where to put them.  They do take up considerable amounts of space and, in many places, available land is at a premium.

An alternative to taking up available land with solar panels is to deploy them on the surfaces of lakes and reservoirs.  A study by researchers at Bangor and Lancaster Universities in the UK calculated the potential electrical output for floating photovoltaic installation on nearly 68,000 lakes and reservoirs around the world.  The lakes and reservoirs selected were no more than 6 miles from a population center, were not in a protected area, and didn’t dry up and didn’t freeze for more than six months each year.  The calculations were based on covering just 10% of the surface area of the bodies of water.

The calculations were evaluated country-by-country.  Five countries could meet their entire electricity needs by floating installations including Papua New Guinea, Ethiopia, and Rwanda.  Many countries, mostly in Africa, South America, and Central Asia, could get between 40% and 70% of their electricity this way.  Most European countries could only meet a few percent of their electricity needs from floating solar, but even that could be significant. 

There are other benefits to floating solar apart from freeing up land.  The panels stay cooler, making them more efficient, and reservoirs lose less water through evaporation and the growth of algal blooms is reduced because there is less light reaching the water.

A brief bout of bad air in Scotland

July 3, 2024 By EarthWise Leave a Comment

Explaining a brief period of poor air in Scotland

Scotland, and the UK in general, used to suffer from sulfur dioxide pollution.  Industrial and domestic emissions, especially from burning coal, contributed heavily to urban air leading to the London smog of the 1950s and the acid rain of the 1980s.  But national air pollution agreements and various international measures have been highly successful in reducing sulfur dioxide emissions.  Desulfurization of coal-fired powerplants and the introduction of ultralow sulfur fuels among other measures have decreased sulfur dioxide emission by 98% since 1970. 

As a result, it came as quite a surprise on May 31st when Edinburgh saw sulfur dioxide levels higher than had been observed in over 30 years.  The levels greatly exceeded air quality objectives for 10 hours with concentrations even creeping towards workplace exposure limits.

What happened?  For once, it was nothing that people did.  Two days earlier, a volcanic fissure eruption took place in the Reykjanes Peninsula in Iceland, some 850 miles from Edinburgh.  Because of an unusual meteorological configuration, the prevailing winds sent the plume of volcanic gases southward towards Scotland.  Had the eruption taken place 60 miles further north or happened a few hours later, the plume of gases would have missed the UK entirely and would have traveled north to the Arctic region.

Icelandic volcanic eruptions have impacted air travel in Europe on a number of occasions.  This non-explosive eruption had little impact outside of its local region, but it turned out to briefly wreak havoc in Scotland.  Fortunately, this pollution event was short-lived.

EV growth and oil demand

June 7, 2024 By EarthWise Leave a Comment

EV growth to slow oil demand

There has been lots of talk recently about the transition to electric vehicles sputtering out.  Several automakers have delayed their EV programs citing reduced demand for the vehicles and lack of profitability.  In the bigger picture, the auto industry as a whole is in a rough patch as rising interest rates and other factors have reduced car buying.

Despite all this doom and gloom talk, sales of electric vehicles will hit an all-time high this year.  Adoption of EVs is accelerating more quickly than many people expected and government policies in China, the United States, and Europe have had a significant impact on vehicle sales.  In China, 37% of new cars sold last year were electric.  The country hit its 2025 target three years early and this year the figure could hit 45%.

But even as electric car sales rapidly increase, oil demand has continued to climb, reaching 100 million barrels a day, slightly more than it was before the COVID-19 pandemic.  The International Energy Agency expects that oil demand will peak before the end of this decade, but oil consumption could remain strong for decades unless there is further policy action encouraging the transition away from it.

Some experts say that the IEA’s models don’t take into account how quickly the world is changing.  New emission rules are expected to speed the adoption of EVs and plug-in hybrids.  In addition, falling battery costs are making the economics of electric vehicles increasingly attractive.  If EV adoption accelerates more rapidly than these models predict, then oil consumption could drop much more quickly.

However, the oil industry is deeply embedded in modern life and is not likely to fade away without a fight.

The world’s largest energy plant

April 19, 2024 By EarthWise Leave a Comment

The largest energy plant in the world is being built in India.  In an area of barren desert in western India near the Pakistani border, Adani Green Energy Limited (or AGEL) is building a sprawling solar and wind power plant that will cover more than 200 square miles.  It will be five times the size of Paris and will produce enough electricity to power 16 million homes.

The Khavda Renewable Energy Park will cost about $20 billion to build and will take about five years to complete.

The success of the plant is critical to India’s efforts to reduce pollution and meet its climate goals.  India is the world’s third-largest energy consuming country.  Even though its energy use and emissions per person are less than half the global average, its enormous population offsets that advantage and its expanding economy and ongoing modernization are driving rapid growth of energy demand.  Energy demand has doubled since 2000 and 80% is still being met by coal, oil, and solid biomass.  India uses massive amounts of coal, and, in fact, the Adani Group of companies is India’s biggest coal importer and a leading miner of the fossil fuel.   Adani represents two sides of the coin.

More than 600 million people in India will be coming into middle and upper income over the next 10 to 15 years and they will have increasing energy needs.  India is in a race to develop clean energy capacity.  If it simply follows the torturous path that China, Europe, and US all have done, the prospects for the global climate are bleak.

Building the world’s largest clean energy plant is just a first small step in the necessary direction.

One in five cars will be electric this year

Electric cars are taking over

There has been lots of turbulence in the electric car industry of late.  Part of it is aggressive publicity campaigns spreading misinformation and part of it is the natural fits and starts associated with major change.  But apart from the ups and downs of individual companies and countries, analysts are projecting another record year for the sales of electric vehicles and are expecting that plug-in cars will account for 20% of all car sales globally.  Much of the growth will be driven by China, where 38% of new car sales will be electric cars.

Global sales of plug-in cars are expected to grow by 21% this year, according to Bloomberg New Energy Finance.  Total projected sales are 16.7 million cars, including 1.9 million in the U.S., 3.4 million in Europe, and 9.7 million in China.  Because of the rapid adoption of electric cars in China, that country is expected to reach peak gasoline demand this year.  In other words, the use of gasoline in China will be diminishing from now on.

The auto industry is in flux.  The traditional big automakers are currently slowing down EV manufacturing as they work to come up to speed with the technology and market demand.  Meanwhile, EV-only carmakers such as Tesla in the U.S. and BYD in China are ratcheting up production. BYD is focusing on emerging economies with its lower-priced offerings.

In the U.S., EV adoption has been slowed somewhat by high interest rates and the slow rollout of EVs by the Big Three automakers.  But many new vehicles by a growing list of automakers will provide customers with more and more choices of EVs to suit diverse tastes and needs.
