Here Come The Lanternflies | Earth Wise

By Leave a Comment

The spotted lanternfly is an invasive pest from Asia that primarily feeds on tree of heaven, which is itself an invasive species that has become widespread.  The real problem is that the lanternfly can also feed on some 70 other plants such as grapevines, maples, fruit trees, and more.

The lanternfly was first discovered in the US in Pennsylvania in 2014 and has since spread to 14 states including New York, Massachusetts, Connecticut, and Rhode Island.  (It was first spotted in New York in Staten Island in 2020 and has continued to spread).

The insect poses a significant threat to New York’s agricultural and forest health. Both the adults and nymphs feed on the sap of plants which stresses them making them vulnerable to diseases and other insect attacks.  They also secrete a sticky substance that attracts molds and interferes with photosynthesis.

Lanternflies are not strong fliers.  They mostly spread through human activity by laying their eggs on vehicles, firewood, outdoor furniture, and other objects that people transport.

The bout of unusually warm weather that the Northeast experienced in early spring is likely to have jumpstarted the spotted lanternfly timeline and hatching could be bumped up to as early as May.

Agriculture officials are asking for people to look for spotted lanternfly egg masses and scrape them off with implements with a sharp edge.  Adult insects should be reported to local authorities and should be killed if at all possible.  There is lots of information online about how to recognize the egg masses and the insects.  Spotted lanternflies are not a direct threat to humans, but they have the potential to cause great harm to vineyards, orchards, and forests.

Banning Gas-Powered Cars | Earth Wise

By Leave a Comment

The European Union has banned the sale of new gas-powered cars starting in 2035.  The vote came after weeks of negotiations related to possible exemptions to the rule.

Germany lobbied for an exemption to be made for cars powered by e-fuels.  These are made by combining hydrogen with carbon dioxide that has been removed from the atmosphere using processes powered by renewable energy.  Because of this source of the carbon dioxide, such fuels are considered to be carbon neutral.  The EU agreed to grant this exemption, so there can be cars that run only on e-fuels after 2035.

About a quarter of carbon emissions in the EU come from transportation.  The new law requires a 55% drop in carbon emissions from new cars by 2030.  Poland voted against the new law, while Bulgaria, Romania, and Italy abstained.  (Italy wanted an exemption for biofuels, but it was not granted).

Here in the US, seven states have adopted rules banning the sale of new gas-powered cars in 2035.  These are California, Maryland, Massachusetts, New Jersey, New York, Oregon, and Washington. 

California has committed to having 35% of new car sales being zero-emission vehicles by 2026, and the number rising to 68% by 2030.

As these policies proliferate around the world, the auto industry is moving ahead to keep up with them.  Most automakers are planning to have substantial parts of their product line be electric by 2030.  Given the financial and physical inertia involved in shifting to electric vehicle production, regardless of what happens with policies around the world, there is little possibility of turning back from the electric vehicle transition.

Electric Cars And Cleaner Air | Earth Wise

By Leave a Comment

Cities are awash in microscopic soot and other pollutants from the tailpipes of vehicles.  Apart from contributing substantially to the warming of the planet, these emissions have a significant impact on human health.  Research at Cornell University has determined that the continued growth of electric cars will lead to cleaner air and reduced human mortality in most if not all U.S. metropolitan areas.

The study, published in Renewable and Sustainable Energy Reviews, estimated the health impact and consequential economic impact of cleaner air in American cities as a result of the transition to electric vehicles.

For example, by 2050, Los Angeles will have 1,163 fewer premature deaths annually, corresponding to $12.6 billion in economic health benefits.  Greater New York City could see 574 fewer deaths a year leading to $6.24 billion in associated economic gains.

Global sales of electric cars have grown steadily.  In 2016, they accounted for less than 1% of the market.  That share grew to 2.2% in 2018, 4.1% in 2020, and 6.6% in 2021.

In the U.S., electric cars accounted for 4.5% of sales in 2021, but in many cities, the numbers were much higher. 

These trends are likely to accelerate as a combination of government policies and major decisions by automakers drive a rapid transition to electrification.  While mitigating the effects of climate change continues to be the main driving force for that transition, the human health benefits will be a very significant reward for doing the right thing for the planet.

Electrifying Delivery Vehicles | Earth Wise

By Leave a Comment

Most of the buzz about electric vehicles relates to passenger cars as the auto industry is making a major transition away from gasoline power.  Recently, pickup trucks have started to get some attention as well as Ford’s electric version of the F-150 truck has hit the streets and the long-awaited Tesla Cybertruck will be introduced next year.  There hasn’t been as much talk about delivery vehicles, but there should be.

There are about 15 million delivery vehicles in the U.S., and they are a significant contributor to greenhouse gas emissions.   The post office alone has a quarter million of them.  Such vehicles are especially attractive candidates for electrification.  Most travel relatively consistent and short routes, which makes it easier for companies to be able to charge them and keep them charged.

Electrifying delivery vehicles in cities is especially important because the vehicles travel into and through residential neighborhoods, spreading pollution and particulates as they go.

Some provisions of the Inflation Reduction Act provide credits for the purchase of commercial vehicles.  Light-duty vans and trucks qualify for a credit of as much as $7,500.  Medium- and heavy-duty trucks qualify for credits as high as $40,000.  In addition, substantial tax credits are available for the installation of charging equipment.

According to a study by the Rocky Mountain Institute, sixty percent of new truck sales could be electric by 2030.  By 2035, the trucking industry could cut its emissions in half.

American companies are already stepping up to the plate.  Amazon plans to deploy 100,000 electric delivery vehicles from new automaker Rivian.  Walmart, UPS, FedEx, and others have also committed to electrified trucks.

The Importance Of Wildlife Crossings | Earth Wise

By Leave a Comment

Highway accidents involving animals are a big problem for both people and animals.  According to the National Highway Traffic Safety Administration, motorists in the United States kill one to two million large animals every year.  About 200 people are killed annually in the U.S. as a result of those collisions with animals.   

These crashes are expensive, too.  Deer-vehicle collisions cost an average of more than $8,000 each; elk-vehicle collisions cost about $25,000; and moose-vehicle collisions cost more than $44,000.

One solution that has been quite effective around the world in reducing car-animal collisions is wildlife overpasses and underpasses.  They are designed to help animals move in search of food and to escape predators and wildfires.  These traffic-spanning bridges and tunnels have been popular in Europe since the 1950s.  They look much like regular overpasses for cars but are decked out with native flora.  The underpasses, which assist shyer and smaller animals, are typically invisible to drivers.

According to a new economic analysis by researchers at Washington State University, wildlife crossings in Washington State save roughly $235,000 to $443,000 every year per structure. 

Wildlife crossing structures range in cost from $500,000 for a tunnel-like underpass to more than $6 million for a broad bridge.  There may soon be many more wildlife crossing structures across the country since $350 million was allotted in the federal Infrastructure Investment and Jobs Act signed into law in 2021.

A Cheap Material For Carbon Capture | Earth Wise

By Leave a Comment

The recently passed Inflation Reduction Act includes significant support for carbon capture technologies. Eliminating fossil fuel burning is essential for halting climate change, but in the interim, methods for capturing emissions of carbon dioxide and either storing it or turning it into usable products are increasingly necessary.

There are a variety of techniques being developed for carbon capture but at this point, none of them are commercially viable.  The best technique in use today involves piping flue gases through chemicals called liquid amines, which bind CO2.  The process requires large amounts of energy to release the bound carbon dioxide so it can be concentrated and stored.  As a result, it is complicated and expensive.

Researchers at UC Berkeley, Stanford, and Texas A&M University have developed a carbon capture method using melamine, which is an inexpensive polymer used to make Formica, as well as low-cost dinnerware, industrial coatings, and other plastics.  Porous melamine itself adsorbs CO2 to a limited extent.  But the researchers discovered that adsorption could be much improved by adding the chemical DETA (diethylenetriamine) to bind the CO2.  In addition, adding cyanuric acid increased the melamine pore size and radically improved CO2 capture efficiency even more.

The result is a material that is more efficient even than exotic carbon capture materials like metalorganic frameworks and is much cheaper and easier to make. The researchers aim to design equipment that can used in industrial facilities, attached to buildings and other structures, or even to the tailpipes of gas-powered vehicles.

Declining Flying Insects | Earth Wise

By Leave a Comment

In recent years, there has been increasing awareness of the global decline in insect abundance.  A recently published survey of the abundance of flying insects in the UK has revealed very troubling results.

The Kent Wildlife Trust and Buglife – two UK-based conservation groups – compared the number of dead insects on vehicles in 2004 and 2021.  In this Bugs Matter Citizen Science Survey, the data was collected by roughly 20,000 ordinary citizens using a smartphone app.

The results were that the number of flying insects in Britain dropped nearly 60% over that time period.  The insects declined most in England and Wales, with drops of 65% and 55%, respectively. 

It is possible that 2004 was a particularly good year for British insects and 2021 an especially bad one, but the findings of this study are consistent with other research around the world showing an alarming decline in insects.  A series of studies in 2019 found that the global mass of insects is shrinking by 2.5% a year and that insects are going extinct eight times faster than reptiles, birds, or mammals.

Insects face multiple overlapping threats including the destruction of wild habitats for farming, urbanization, pesticides, and light pollution.  On top of these things is climate change which is disrupting ecosystems in multiple ways.

Insects play a vital role in pollinating crops, consuming organic waste, killing pests, and as essential parts of multiple ecosystems.  Severe insect declines can potentially have dire global ecological and economic consequences.

Air Pollution: The Greatest Danger | Earth Wise            

By Leave a Comment

The effort to reduce and ultimately eliminate the use of fossil fuels has largely been driven by the potentially catastrophic consequences of global climate change.  The need to stop dumping greenhouse gases into the atmosphere has become increasingly urgent.  But there is an equally compelling reason to stop burning fossil fuels.  According to a study published in the journal Lancet Planetary Health, outdoor air pollution is “the largest existential threat to human and planetary health.”

Pollution of various types was responsible for an estimated 9 million deaths around the world in 2019.  Half of those fatalities – 4.5 million deaths – were the result of outdoor air pollution coming from vehicles and industrial sources like power plants and factories.

The number of deaths attributed to air pollution has increased by 55% just since the year 2000.

The growth in air pollution deaths has offset a decline in deaths from other pollution sources that especially affect people living in extreme poverty, such as indoor air pollution and water pollution.  Overall, countries with lower collective incomes tend to bear a disproportionate share of pollution deaths.  Roughly 16% of deaths around the world are attributable to pollution, also resulting in more than $4 trillion in economic losses.

The peer-reviewed study was produced by the 2017 Lancet Commission on Pollution and Health.  The study notes that despite the enormous health, social, and economic impacts of pollution, preventing it is largely overlooked in the international development agenda.  The study calls upon governments, businesses, and other entities to abandon fossil fuels and adopt clean energy sources.

Electric Cars On The Rise | Earth Wise           

By Leave a Comment

The first quarter of the year was a tough one for the U.S. auto industry.  Overall sales of cars and trucks were down 15.7% compared with last year.   Automakers have been dealing with shortages of computer chips and other supplies, resulting in slowdowns in production.

The one major exception to the trend has been sales of electric cars.  In the first quarter, U.S. electric vehicle sales were up 76% compared with last year.  This was enough to double EV’s market share to 5.2%, up from 2.5% last year.

Reaching a five percent market share is a significant indicator that electric vehicles are becoming mainstream.  According to many industry analysts, this is just the beginning of a major ramp-up in EV sales.

The strong results in the first quarter were largely driven by one company – namely, Tesla.  Tesla has been expanding rapidly and has been proactive and creative in avoiding delays due to parts shortages.  Tesla’s best-selling car is now the Model Y, which is an SUV implementation of its Model 3 design.  Overall, the company is now producing cars at a rate of more than 1 million per year and has recently opened new manufacturing plants in Texas and in Germany.

But Tesla is not the only story in the world of electric vehicles.  Mass production is beginning for Ford’s F-150 Lightning truck. 

Nissan, Hyundai and Kia have electric cars on the market and shortly near-twin electric models jointly developed by Subaru and Toyota will be available as well.

The electrification of vehicles is an essential step in reducing greenhouse gas emissions.  With gasoline at painfully high prices, electric cars are more attractive than ever.

Unhealthy Air | Earth Wise

By Leave a Comment

According to the World Health Organization, almost the entire global population – 99% in fact – breathes air that exceeds WHO air quality limits and threatens their health.

Air quality is of great concern everywhere.  Over 6,000 cities in 117 countries monitor air quality, but the people living in those cities are still breathing unhealthy levels of fine particulate matter and nitrogen dioxide. The WHO is citing these findings as a compelling reason to curb fossil fuel use and to take other steps to reduce air pollution levels. 

There is growing number of studies of the damage air pollution does to the human body.  Even low levels of many air pollutants can cause significant harm.  Particulate matter – especially so-called PM2.5 – is capable of penetrating deep into the lungs and entering the bloodstream, contributing to cardiovascular, cerebrovascular, and respiratory problems. 

Nitrogen dioxide is associated with respiratory diseases – especially asthma – and leads to respiratory symptoms, hospital admissions, and visits to emergency rooms.

The WHO is calling to governments around the world to take additional steps to improve air quality including adopting stricter air quality standards, supporting the transition to clean household energy sources, implementing stricter vehicle emission standards, reducing the use of incineration, and many other actions.

According to the WHO, cities in high-income countries fare better in terms of air quality, but very few places avoid unhealthy air entirely.   Seven million deaths a year are linked to unhealthy air quality.  It is a global crisis that cannot be ignored.

Electric Car Sales Surge | Earth Wise

By 1 Comment

During the fourth quarter of 2021, overall auto sales in the US fell by 21.3% compared to the same quarter of 2020.  At the same time, sales of electric cars grew by 73%.  Is this the beginning of the end for the Gasoline Era, or was it a just an anomaly during the COVID pandemic?

The biggest factor for the big drop in car sales was probably on the supply side.  The ongoing chip shortage as well as other supply-chain problems made it difficult to find many desired vehicles.  Meanwhile, the soaring electric car sales in the US was mostly soaring Tesla sales.  According to Kelley Bluebook, 72% of all electric cars sold in the US in the fourth quarter were Teslas.  For a number of reasons related to its in-house software development and it unified computer architecture, the chip shortage has been far less of a problem for Tesla than for other car brands.  So, Tesla bucked the overall market decline because it actually had cars to sell.

So, once these supply-chain issues are resolved, will the car market return to “normal”?  That is actually unlikely.  Apart from the short-term issues, there are long-term factors that are changing the automobile market.

There is far more public attention on EVs these days.  Multiple commercials during the Superbowl demonstrated that.  All the carmakers are gearing up for an electric future as government policies push for it.   Electric vehicle sales are already booming in Europe.  Cars are fashion products and electric cars are the latest trend.  Electric car sales will continue to grow at an impressive pace this year.  According to many observers, the recent trend could be the beginning of an avalanche.

A Car-Free Zone In Berlin | Earth Wise

By Leave a Comment

The regional parliament in Berlin is considering the creation of a car-free zone in the German capital as a result of a petition from a local advocacy group.  The group – called the People’s Decision for Auto-Free Berlin – collected 50,000 signatures, which was enough to require the Berlin Senate to take up the issue.

The city ban would apply to the space ringed by the S-Bahn train line, which circles the city center.  Known as the Ringbahn, the area enclosed was already established as a low-emission zone in 2008.  It is 34 square miles in area, larger than Manhattan.  The ban would restrict vehicle use to trucks, taxis, emergency vehicles, and limited car-sharing programs.

In Berlin, a combination of regular trains, ample bike lanes, and a robust network of public buses makes getting around without a car more practical than in many other major cities.  In fact, automobiles account for only 17% of trips inside of the Ringbahn.

Even so, there is still a lot of car traffic in the city center.  Advocates for the plan believe it would lead to a city with cleaner air and more livable spaces for its citizens.

If the Berlin Senate rejects the measure, the advocacy group will seek to collect 175,000 signatures, which would force the Senate to consider the matter for a second time.  If it is rejected again, it would automatically go to a referendum in 2023.

In Europe, it appears that the revolution in transportation may not just be one about electric vehicles, but in some places may be toward the removal of vehicles in general.

An Arctic Bus | Earth Wise

By Leave a Comment

People have built vehicles for all sorts of extreme environments.  There are deep-sea exploration vessels and there have been lunar and Mars rovers.  But one thing that hasn’t existed so far are buses to transport groups of people around in extreme conditions in the Arctic.  Engineers at two Russian Universities are developing a passenger bus for riding in the Far North.   The project is being funded by the Russian Federation Ministry of Science and Higher Education and the URAL Automobile Manufacturing Plant.

The requirements for the vehicle are daunting.  The bus must be operable at extreme temperatures – 60 below zero Fahrenheit and lower – and have no difficulties even in challenging off-road conditions.

Current Arctic crew buses are not capable of getting through snow blockages and the all-terrain tracked vehicles that can get through them do not have sufficient passenger capacity. In addition to being able to go through snowbanks, the bus should be able to float on water for an hour.

Apart from its ability to withstand harsh Arctic conditions, the bus will also have a quarters module.  This means that it will have an autonomous life-support system for passengers in case of emergency.  The quarters module will be designed to sustain up to 20 people for up to 24 hours.  The module might also be used to hold medical equipment, thereby enabling practitioners to reach remote settlements and treat patients. 

The first tests of prototypes for the bus will be conducted in the near future.  The project aims to have the new Arctic Bus design complete and ready for manufacture by the end of 2023 and it will go into production in 2024.

Cheaper Electric Cars | Earth Wise

By 1 Comment

The price of the batteries that power electric cars has fallen by about 90% since 2010.  This continuing trend will eventually make EVs less expensive than gas cars.

For many years, researchers have estimated that when battery packs reach the price of $100 per kilowatt-hour of energy storage, electric cars will cost about the same as gasoline-powered vehicles.  In 2021, the average price of lithium-ion battery packs fell to $132 per kilowatt-hour, down 6% from the previous year.  According to analysts, batteries should hit the average of $100 as soon as 2024.

It is not the case that as soon as the $100 level is reached, EVs will abruptly reach cost parity.  Across different manufacturers and vehicle types, the price shift will occur at different rates.  However, by the time batteries reach $60 a kilowatt-hour, EVs will be cheaper than equivalent gasoline models across every vehicle segment.

It is not known exactly when EVs will cost less than gasoline models, but there is little doubt that this point is coming.  We have only been talking about the purchase price of a new vehicle.  When one looks at the total cost of ownership of a vehicle, including fuel, insurance, maintenance, and depreciation, it is a different story.

Because of savings on fuel and maintenance, EVs are already in many if not most cases cheaper to own than gas-powered cars.  The Department of Energy provides an online calculator to help consumers estimate the cost differences between gasoline and electricity.

In any case, the number of electric cars on the market is increasing and the number of gas-powered cars will be shrinking.  Sooner or later, we will all drive electric.

Iron Flow Batteries | Earth Wise

By Leave a Comment

Lithium-ion batteries power computers, cell phones, and increasingly, automobiles.  They started out being rather expensive but have become dramatically cheaper over the last decade, with prices dropping about 90%.  Batteries are needed to store clean power from wind and solar generation and lithium-ion batteries are increasingly being used for that purpose as well.

Utility-scale energy storage requires substantial battery installations and battery cost is still very much an inhibiting factor in the widespread adoption of the technology.  Lithium-ion battery costs continue to drop but because they require expensive materials like lithium and cobalt, there are limits to how low their prices are likely to get.

As a result, researchers have continued to seek ways to produce batteries made out of cheaper materials.  Among the more promising technologies are flow batteries, which are rechargeable batteries in which electrolyte flows through electrochemical cells from tanks. 

Flow batteries are much larger than lithium-ion batteries and include physical pumps to move electrolytes.  They typically are sold inside shipping containers.  Clearly, such batteries are not suitable for use in vehicles, much less in consumer electronics.  Nevertheless, they represent a practical option for grid storage.

A company called ESS has developed an iron flow battery suitable for utility energy storage.  Clean energy firm CSB Energy plans to install iron flow batteries at several solar projects across the U.S. that will store enough energy to provide power 50,000 homes for a day.  According to ESS, the iron-based batteries should sell for about half the price of lithium-ion batteries by 2025 and be able to store energy for longer periods.

Banning Gas Cars | Earth Wise

By Leave a Comment

The transition to electric vehicles from gas-powered vehicles is essential for reducing greenhouse gas emissions as well as air pollution in general.  Currently, transportation is responsible for 30% of greenhouse gas emissions in the United States.

There is no doubt that there is surging interest in electric cars.  There are now millions of them being sold around the world each year.  But they still represent a small fraction of new car sales in most places.  Notable exceptions are several European countries such as Norway and Switzerland where plug-in vehicles are dominant.  In the United States, on the other hand, EVs still represent less than 3% of new car sales.

Given the urgency in reducing vehicle emissions, many countries around the world have devised plans, goals, or laws to end the sale of gasoline cars.  Gas car bans vary quite a bit around the world, but they are being implemented in many places.

There are 28 countries and US states that have imposed gas car bans to take effect over the next five to 20 years.  These include European countries like Norway, Belgium, Austria, Netherlands, Denmark, Iceland, Ireland, Sweden, Scotland, Slovenia, the UK, France, and Spain.  Asian countries include South Korea, India, Japan, China, Singapore, Sri Lanka, and Taiwan.  In the Middle East, Israel and Egypt have announced bans.  Here in the US, New York and California both have bans starting in 2035.  Canada also has announced a ban.

Car manufacturers have seen the writing on the wall.  Most have started adding EVs to their lineups.  Many have announced their own timetables for phasing out gas cars entirely.  There are more than 15 new electric models available this year and there are many more to follow next year.

The Spotted Lantern Fly Is A Big Problem | Earth Wise

By Leave a Comment

The spotted lanternfly is an invasive pest from Asia that arrived in the United States seven years ago.  It is a handsome and colorful insect, but it feeds on the sap of more than 70 plant species, leaving them susceptible to disease and destruction from other natural antagonists.  It destroys fruit crops, trees, and plants by hopping from plant to plant, crop to crop, and tree to tree.

Several states have established quarantines aimed at preventing the spread of the insects.  Pennsylvania, where they were first detected in the U.S., issued an Order of Quarantine and Treatment that imposes fines and even potential criminal penalties on anyone who intentionally moves a spotted lanternfly, at any stage of its life, from one sort of location to another.  The insects hop and fly only short distances, but they can hitch a ride on vehicles, clothing, and other objects that people bring with them.  They have now spread to at least nine states, primarily in the Northeast.

Lanternflies arrived in New York City last year and quickly made it to the Most Wanted List for environmentalists.  The City’s Parks Department says: “If you see a spotted lanternfly, squish it, dispose of it, and report it to us.”  New York’s Department of Agriculture has asked people in the Finger Lakes region, home of numerous vineyards, to collect specimens and provide specifics on where they were found.

Lanternflies are harmless to humans, but they threaten everything from oak, walnut, and poplar trees to grapes, almonds, and fruit orchards.  As the species continues to spread across the country, federal and state officials have a unified message:  if you come across a spotted lanternfly, kill it.

Electrifying The Federal Fleet | Earth Wise

By Leave a Comment

The federal government owns and operates about 645,000 vehicles.  Among them are about 200,000 passenger vehicles, 78,000 heavy-duty trucks, 47,000 vans, 847 ambulances, and three limousines.   About 225,000 vehicles are operated by the Postal Service.  

Each year, these vehicles are driven about 4.5 billion miles and use about 400 million gallons of gasoline, producing 3.5 million tons of greenhouse gases.

President Biden signed an executive order in January directing federal officials to devise a plan for converting the entire fleet to clean and zero-emission vehicles.  So far, the work has been slow. 

According to a new report from Atlas Public Policy, accelerating the push for electric vehicles in the federal fleet could save taxpayers billions of dollars.

Electric vehicles have lower fueling and maintenance costs as well as a smaller environmental impact.  According to the report, the government could replace 40% of its light-duty vehicles and buses not owned by the Postal Service with cheaper plug-in alternatives by 2025.  By 2030, it could replace 97% of such vehicles with EVs for a lifetime savings of more than $1 billion.  Furthermore, by 2025, it would be possible to replace nearly all mail trucks with EVs for a savings of $2.9 billion.

The federal fleet represents an opportunity to encourage transportation electrification to happen much more quickly.  Apart from the economic and environmental benefits, having an electrified federal fleet would increase public awareness of the practicality and benefits of electric vehicles.

Electric Cars Are Coming Sooner Than Expected | Earth Wise

By Leave a Comment

It is widely believed that electrification is the future for vehicles.  The only question is how long the transition will take.  Predictions are all over the map, but the recent trend is to revise those predictions to say it will happen sooner than previously thought.

A recent report from the international accounting firm Ernst & Young predicts that EV sales in the US, China, and Europe will surpass those of fossil-fuel-powered vehicles five years sooner than previously expected.  The report forecasts that fossil-fueled vehicles will represent less than 1% of global sales by 2045, taking their place among other historical but essentially abandoned technologies.

Europe is expected to be the leader in EV adoption.  The forecast is that EVs will surpass legacy vehicles by 2028.  China is expected to follow by 2033.  The US is lagging behind, but even here, electrics are expected to achieve a majority of car sales by 2036.

Plug-in vehicle sales have surpassed a 10% market share in California and Tesla now has a 1.7% share of the total US car market.  Norway is the global EV leader with 3 out of 4 car buyers choosing electrics.  In that country, Tesla’s Model 3 is the top-selling vehicle of any kind.  In Switzerland, 40% of car sales are EVs or hybrids.

There are many variables that will affect the timetable for the EV transition.  Among them are the timetable for widespread use of autonomous vehicle technology, the effects of policy initiatives by governments around the world, the development of charging infrastructure, and the evolution of electricity generation and energy storage.

In any case, looking at the product roadmap for virtually every automobile manufacturer makes it clear that electric cars are the future.

Scaling Up Green Hydrogen | Earth Wise

The global hydrogen market generates about $150 billion dollars a year.  The bulk of the market consists of hydrogen used to produce ammonia, refine oil, and produce methanol.  Advocates for hydrogen foresee a $600 billion a year market based on power and industry uses, mobility and transport uses, chemical feedstocks, and construction.  But the problem with expanding the use of hydrogen is that the vast majority of hydrogen in use today is produced from fossil fuels such as natural gas and coal and producing it creates carbon dioxide emissions.

The great hope of the industry is “green hydrogen”- hydrogen produced either without using fossil fuels at all or by capturing and storing the emissions generated. The most likely approach is electrolysis – using electricity to produce hydrogen from water.

Billions of dollars are being invested by both governments and by large oil companies in a race to scale up electrolysis and make it economically attractive.  According to the Hydrogen Council industry lobby group, at least $300 billion is expected to be invested globally over the next decade aimed at developing the green hydrogen that could one day meet almost a fifth of global energy demand.

Many argue that producing green hydrogen with electrolysis is an extremely inefficient way to utilize renewable energy.  Critics of hydrogen-powered vehicles particularly make this argument.   But industrial applications of hydrogen that currently use large amounts of fossil fuels – such as steel manufacturing – may be places where green hydrogen would make a real dent in global emissions.

The race to clean up hydrogen is definitely on.
