Electric Cars And Cleaner Air | Earth Wise

January 20, 2023 By EarthWise Leave a Comment

Electric cars can help clean the air

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

October 12, 2022 By EarthWise Leave a Comment

Electrifying delivery vehicles is important for the climate

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.

Bidding ‘Adieu’ To Single-Use Plastics | Earth Wise

July 27, 2022 By EarthWise Leave a Comment

Since the 1950s, more than nine billion tons of plastic have been produced, and 50% of that has been during the past 15 years.  While there are some use cases for plastic that are important, it generally serves as the poster child of our throwaway culture.

Plastic pollution can be found everywhere on earth, from the top of the tallest mountains to the bottom of the deepest oceans.  It’s in our food, water, and air. 

By 2040, researchers predict that there will be nearly 90 million tons of plastic pollution entering the environment each year.  By some estimates, single-use plastics account for half of all our plastic waste.    

Many cities, states, and even countries are limiting or even banning single-use plastics.  Canada recently announced a ban on single-use plastics.  The ban includes things like plastic shopping bags, cups, cutlery, straws, stirrers, and take-out food containers.

The ban will phase in over the next several years, beginning with a ban on the manufacture and import of single-use plastics by the end of this year.  Sales of these items will be prohibited in 2023, and the export of plastics will cease by the end of 2025.  

Canada’s southern neighbor, the United States, leads the world in plastic waste generation.  While some states have approved single-use plastic reforms, most of the effort at the federal level has focused on improving recycling rates.  However, a recent report from several environmental organizations found that plastic recycling rates in the U.S. have actually declined in the last several years, from an already-dismal 8.7% to less than 6%.    

Suggesting the plastic waste problem can be solved with improved recycling rates is greenwashing the issue.

Record Renewable Use In California | Earth Wise

May 19, 2022 By EarthWise Leave a Comment

California, the most populous state, is the second largest electricity user.  Only Texas, the second most populous state, uses more energy, in part because it consumes large amounts in refining fossil fuels. Overall, California uses about 8% of the electricity generated in the U.S.

Thus, it was a significant milestone when briefly, on April 3, a record 97.6% of the energy on California’s statewide grid came from renewable energy resources.  (The previous record of 96.4% was set just a few days earlier).

Renewable energy’s share of the power typically peaks in the spring when mild temperatures keep demand relatively low and higher sun angles drive greater solar energy production.

On April 8, a record peak solar power production was set at 13,628 megawatts just after noon.  On March 4, the state set an all-time wind generation record of 6,265 megawatts. 

California now has over 15,000 MW of grid-connected solar power and 8,000 MW of wind.  Another 600 MW of solar and 200 MW of wind are coming online by June.  The state also has about 2,700 MW of energy storage online and that will climb to 4,000 MW by June.

In 2020, 34.5% of the state’s retail electricity sales came from wind and solar sources.  Adding in hydropower and nuclear power, nearly 60% of the state’s electricity came from non-fossil fuel.  Despite the effects of drought on hydropower generation and the impact of the pandemic on the pace of renewable energy projects, California continues its dramatic transition to sustainable energy.

Electric Cars On The Rise | Earth Wise           

May 16, 2022 By EarthWise Leave a Comment

Sales of electric vehicles surging

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.

Electric Car Sales Surge | Earth Wise

March 24, 2022 By EarthWise 1 Comment

Electric car sales have surged despite falling overall auto sales

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.

Banning Gas Cars | Earth Wise

November 12, 2021 By EarthWise Leave a Comment

Many states and countries have passed gas car bans

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.

Electric Cars Are Coming Sooner Than Expected | Earth Wise

September 30, 2021 By EarthWise 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.

Promoting Biodiversity In Agriculture | Earth Wise

September 13, 2021 By EarthWise Leave a Comment

The best methods to promote biodiversity in agriculture

The organic foods industry is one of the fastest growing agricultural segments in the United States.  According to the Organic Trade Association, U.S. organic sales reached $61.9 billion in 2020, a jump of more than 12% over the previous year. 

Organic food has many benefits.  Organic food is free of antibiotics, growth hormones, and GMOs, and is grown using fewer pesticides.  Organic farming tends to be better for the environment by reducing pollution, conserving water, reducing soil erosion, increasing soil fertility, and using less energy.   And it’s also better for the health of nearby wildlife as well as the people who live close to farms. 

But when it comes to promoting biodiversity in agriculture, is organic farming the only alternative to conventional agriculture? It turns out it’s not – at least according to a new study recently published in the journal Trends in Ecology and Evolution. 

According to an international research team led by the University of Göttingen in Germany, a landscape mosaic of natural habitats and small-scale and diverse cultivated areas is the key to promoting biodiversity on a large scale in both conventional and organic agriculture.

According to the research team, areas cultivated to organic standards have one third more species, but don’t reach the yield level of conventional farming.  This means that more land would need to be cultivated organically in order to produce the same amount of food.  But as larger areas are cultivated, the advantages for biodiversity would disappear.    

Landscapes with small fields, long edges, high crop diversity, and at least 20% near-natural habitats can promote biodiversity significantly more than just organic certification.

Have We Reached Peak Internal Combustion Engine? | Earth Wise

August 3, 2021 By EarthWise 1 Comment

Global sales of gas-powered cars may have peaked in 2017

According to new analysis from Bloomberg New Energy Finance, global sales of gas-powered cars may well have peaked in 2017, representing a significant milestone in the transition to electric vehicles.

Demand for gas cars dropped in 2018 and 2019, and then plummeted in 2020 as a result of the coronavirus pandemic.  While sales are surely picking up as the pandemic ebbs, the increasing demand (and supply as well) for plug-in vehicles is likely to put gas-powered cars in a state of permanent decline.

Global EV sales are projected to go from 3.1 million last year to 14 million in 2025.  The growth is being driven by falling battery prices, government policies, and increasing choices of vehicles.  Virtually all automobile manufacturers are introducing electric vehicles over the next couple of years and increasing numbers of them are planning a complete transition to EVs in the near future.  Projections are that EVs will account for the majority of new car sales by 2035.

While all this progress is encouraging, there are still over a billion gas- and diesel-powered cars on the road and the fleet turns over slowly.  The current average operating life of cars here in the US is 12 years.

To reach the net-zero carbon emission goals by 2050 as many governments have mandated, additional policies and regulations will be needed.  For example, electric cars will need to account for essentially all new sales by 2035, not just the majority.  Reaching net-zero by mid-century will require all hands on deck, including trucks and heavy commercial vehicles that have barely started to become electrified.

The Plunging Cost Of Lithium-Ion Batteries | Earth Wise

May 11, 2021 By EarthWise Leave a Comment

The cost of lithium-ion batteries is plunging

Lithium-ion batteries are the power source for phones, laptops, and electric cars.  These rechargeable batteries were first commercially introduced in 1991.  Since then, their performance has improved, and their cost has dropped tremendously.

There have been dramatic cost declines in many advanced technologies.   The price of big-screen televisions is a prime example.  Most people think of solar photovoltaic panels as the most exceptional case.  In the 1970s, solar panels cost over $100 per watt. Today, they are 20 cents a watt.

How much lithium-ion batteries have dropped in price has been somewhat unclear.  This is because much of the information about battery costs is in the form of closely held corporate data.  Most lithium-ion batteries are not sold directly to consumers but rather are built into consumer electronics and cars.  Large companies like Apple and Tesla buy batteries by the millions or manufacture them themselves, and the true costs are not publicly disclosed.

Recently, MIT researchers have carried out an extensive analysis of lithium-ion battery costs over the past three decades.  The researchers found that the cost of these batteries has dropped by 97% over that period.

It is clear that the decline in battery costs has been an enabler of the recent growth in sales of electric vehicles.  It is also clear that further declines in lithium-ion battery costs are likely to increase the batteries’ usage in stationary applications such as storing energy from intermittent green power sources like solar and wind.

The batteries have ever-improving energy density (energy stored within a given volume) and specific energy (energy stored within a given mass.)  As lithium-ion batteries continue to get better and cheaper, their role in the world continues to grow.

Vehicle Electrification On The Rise | Earth Wise

August 21, 2020 By EarthWise Leave a Comment

increasing vehicle electrification

Nearly 70% of U.S. oil consumption is for transportation and transportation accounts for 28% of the country’s greenhouse gas emissions.  Therefore, technology improvements in transportation that can reduce emissions are a key element of combating climate change.  The highest impact strategy is the electrification of the transportation sector, and it is definitely accelerating.

Demand for electric vehicles is growing for multiple reasons.  These include long-term cost savings, tax incentives, declining battery costs, and greater environmental awareness.  This year, about 2.7 percent of global passenger vehicle sales will be for electric vehicles.  It is still a fairly small number, but that number is growing rapidly.  It is expected to be 10% in 2025, 28% in 2030, and more than half of all vehicle sales by 2040.  By that year, more than 30% of passenger vehicles on the road worldwide will be electric.  The numbers for electric buses, delivery vans and trucks, mopeds, scooters, and motorcycles are expected to be even higher.

The environmental impact of electrification will be significant in reducing carbon emissions and pollution in general.  Electric vehicles already reduce oil demand by a million barrels a day.  By the year 2040, they will displace nearly 18 million barrels of oil a day and reduce CO2 emissions by 2.5 billion tons per year.

Electric cars still face challenges.  They are still more expensive than gas-powered cars, but their cost-benefit analysis is changing rapidly as technology improvements and volume efficiencies drive down the cost of battery packs.  Analysts predict that electric vehicles will achieve price parity with internal combustion vehicles in as soon as two years but in any case within the next ten years.

Massachusetts And Energy Policy | Earth Wise

August 4, 2020 By EarthWise Leave a Comment

Massachusetts and clean energy

The transition to a renewables-based energy future continues to accelerate, but there are still many forces that can slow it down.  Government policy has a major role to play.  At the moment, the federal government is trying to prop up the fossil fuel industry with financial incentives and rampant deregulation.  So more than ever, innovative policies at the state level are essential drivers for revolutionizing the energy system.

One state where policy is trying to make a big difference is Massachusetts, which has created the Clean Peak Energy Standard or CPS, finalized and approved in late March and now taking effect.   A clean peak standard is a regulatory tool to reduce the costs and environmental impact of periods when electricity demand is highest, and generation tends to be the most polluting.  The CPS requires electric retailers to procure a minimum percentage of their annual electricity sales from renewable generation or energy storage.  That minimum amount will increase each year.

The CPS is formulated to incentivize better utilization of clean energy technologies to supply power when energy demand is high.  The problem is that there are times when the sun is not shining and the wind isn’t blowing, but energy demand is at its highest.  The solution is to use energy storage technologies that can supply power when it is needed.  Furthermore, storage can be relied upon during times of extreme weather that cause power outages.

Massachusetts has already started using energy storage in its grid.  The small town of Sterling installed an energy storage system in 2016 that provides crucial backup power to the police station and emergency dispatch center, thereby keeping first responder operations running even during extended power outages.

Booming Electric Car Sales

September 12, 2019 By EarthWise Leave a Comment

Electric cars are becoming more and more commonplace over time.  There is no place in the world where this is more evident than in Norway.  This year, about half the new cars sold in Norway have been electric.  This compares to only 25% just last year.  In March alone, nearly 60% of vehicle purchases in Norway were plug-in cars, outselling gas and diesel cars for the first time ever.

Norway has encouraged the switch to electric transportation by making battery-powered cars tax exempt as well as offering various other incentives.  This is all part of the country’s plan to end the sale of fossil fuel cars entirely by 2025.

Although Norway leads the world in electric car sales on a per capita basis, there are many other places seeing rapid growth.  In Maryland, for example, so many electric cars were sold in the past year that the state’s tax credit program, which has a $3 million annual budget, ran out of money seven months before the end of the fiscal year.  Between 2017 and 2018, the number of EVs registered in Maryland doubled to over 18,000.

New York has also seen robust growth in electric vehicles.  There are now more than 40,000 plug-in cars registered in New York State.  About a third of those are Tesla models, with the increasingly popular Tesla Model 3 rapidly becoming the dominant plug-in car in the state.  In fact, this year the Tesla Model 3 has accounted for about 60% of all plug-in car sales in the United States.

Not only are electric car sales going up, so are the options for car buyers.  Within the next year or two, there will be numerous new electric car choices available from multiple manufacturers appealing to the tastes of a growing range of car buyers.

Meal Kits And The Environment

June 11, 2019 By EarthWise Leave a Comment

Meal kit services have become extremely popular in recent years.  These are companies that deliver a box of pre-portioned ingredients and a chef-created recipe to your door to make home-cooked meals easy and practical for busy people.  Leading companies like Blue Apron, HelloFresh, and Plated have been joined by dozens of others competing in the meal kit market.  As of last year, annual sales for these things were over $3 billion and growing at more than a 20% annual rate.

A major rap against meal kits has been their environmental impact, mostly centered around the amount of packaging waste they generate.  While there is most certainly lots of packaging waste associated with meal kits, it turns out that their overall carbon footprint is actually rather good compared with conventional ways to make homecooked meals.

A study from the University of Michigan looked at the cradle-to-grave impact of meal kits, taking into account every major step in the lifetime of the food ingredients and the packaging – agricultural production, packaging production, distribution, supply chain losses, consumption, and waste generation.

Surprisingly, meal kits have a much lower overall carbon footprint than the same meals made from ingredients purchased at the grocery store – even including their packaging.  The main reason is that pre-portioned ingredients and a streamlined supply chain lower overall food losses and waste for meal kits compared to store-bought meals.  Pre-portioning simply results in fewer ingredients that end up being wasted.  Meal kits also have radically different supply chain structures than foods sold in supermarkets.

Whether the economics and culinary aspects of meals kits are advantageous for many people is an open question, but apparently from an environmental perspective, they are just fine.

Australian Plastic Bag Ban

December 31, 2018 By EarthWise Leave a Comment

Last summer, the two largest supermarket chains in Australia – Coles and Woolworth’s – decided to stop offering single-use disposable plastic bags to customers.  The initial public reaction was decidedly negative.   However, within just three months after the radical change, the country’s National Retail Association reported an 80% drop in the consumption of plastic bags nationwide.

In that three-month period, it is estimated that 1.5 billion bags have been prevented from use.   Some retailers are reporting reduction rates as high as 90% in the use of the bags.  The move by the big supermarkets has paved the way for smaller businesses to follow suit. The smaller businesses typically can’t afford to risk the wrath of their customers with a major change like this. Customers have to learn to bring their own bags or buy reusable bags at the store.

In much of Australia, the phase-out of plastic bags has been legislated, but the state of New South Wales, home to Sydney, the country’s largest city, has not enacted such legislation. So, supermarkets themselves are doing the work of getting rid of the bags.

The change has not been without hiccups.  For the first couple of months after the plastic bag ban was put in place, Woolworth’s saw poor sales in its stores.  However, customers eventually got used to the new way of doing things and sales levels returned.

Disposable plastic bags often find their way into the oceans where they break down into microparticles. Studies have shown that these plastic bits are ingested by a wide variety of marine life.  For example, a UK study found that 100% of sea turtles in the Pacific and Atlantic oceans as well as the Mediterranean Sea had plastic in their digestive systems.

According to the FDA, approximately three-quarters of all antibiotics used in the U.S. are fed to livestock for non-therapeutic purposes.  This routine administration of antibiotics promotes the development of antibiotic-resistant bacteria, which can spread to animals and humans.   And as antibiotic-resistant bacteria spreads, medicines used to treat human diseases can become less effective. Antibiotic resistant infections kill 90,000 Americans each year.
