Halloween pumpkins

By Leave a Comment

According to the National Retail Federation, spending on Halloween festivities this year by the 72% of Americans who plan to celebrate is expected to total $11.6 billion – or about $104 per person.  The annual consumer survey also found that 67% of Americans plan to pass out candy this year, and nearly 50% of Americans plan to carve a pumpkin.

To produce enough pumpkins for Halloween, farmers grow lots of them every year.  In fact, more than two billion were grown in 2020 alone.  But the vast majority of pumpkins are never eaten; instead, most are carved and placed on porches across the country.  This means Americans spend hundreds of millions of dollars on pumpkins annually just to toss them in the trash when Halloween ends. 

When pumpkins are placed in landfills, they produce methane gas.  Methane is a potent greenhouse gas that affects climate change by contributing to increased warming. 

Instead of throwing pumpkins into the landfill, there are several responsible ways to dispose of them. 

If the pumpkin is still in good shape, use the outer, meaty part of the pumpkin to make pumpkin puree.  The pumpkin seeds can also be scooped out, rinsed, seasoned, and then baked in the oven, resulting in a delicious snack.

Pumpkins also have the potential to turn into great soil through composting. Pumpkins can help naturally add moisture to compost piles that need to be damp in order to effectively decompose food waste.   

If eating or composting the pumpkins isn’t an option, consider donating them to a local farm.  Farmers will often collect pumpkins as treats for their pigs, goats, and other animals.

Clean energy investment at record levels

By 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.

Record energy transition investments

By Leave a Comment

Global investment in the energy transition – that is, the transition away from fossil fuels – increased by 17% in 2023, reaching a new high of $1.8 trillion dollars.  That number includes spending on electric vehicles and their associated infrastructure, electrification of the power grid, and various other changes to the energy system.

Electrified transport was the largest sector for spending, accounting for $634 billion dollars.  This figure includes spending on electric cars, trucks, buses, two- and three-wheeler, and commercial vehicles, as well as charging stations and other associated infrastructure.

The renewable energy sector – including wind, solar, geothermal, and biofuel power plants – accounted for $623 billion.  The third largest investment was $310 billion in power grid investments.

China spent the most of any country by a large margin, investing $676 billion. The EU, U.S., and UK combined accounted for $718 billion. 

These numbers reflect the rapid growth of clean energy across the globe and are obviously quite large.  However, the pace at which clean energy technology is growing is not fast enough to achieve the goal of net-zero emissions by mid-century that most countries have set.  By many accounts, energy transition investments would need to average $4.8 trillion per year for the rest of the decade to be on track.  This is about 5.6% of the global gross domestic product that is currently about $85 trillion per year.  By comparison, the U.S. currently spends about 5.7% of its GDP on energy.

Sustainable New Year’s resolutions

By Leave a Comment

Every year, millions of people around the world make resolutions to spark positive change in the new year.  Popular resolutions include improving health and fitness, traveling more, spending less, and so on. With 2024 just around the corner, here are six resolution ideas to reduce our climate impact: 

Shop More Sustainably.  Choose eco-friendly brands and products with minimal environmental impact, including locally-produced goods and reusable items whenever possible. 

Switch To Clean Energy.  Purchase green power, install renewable energy systems to generate electricity, or switch to renewable resources for home and water heating and cooling needs. 

Reduce Food Waste.  Food waste is a significant global issue with environmental, economic, and social implications.  In the U.S., an estimated 30-40% of the total food supply is never eaten.  Meal plan and only shop for what you need.  And freeze any leftovers.   

Adopt A More Plant-Based Diet.  Transition to a more plant-based diet in order to shrink the ecological footprint of food production.  Resource-intensive animal-based foods like meat, dairy, and eggs are one of the chief contributors to climate change. 

Reduce the Carbon Footprint of Transportation.  Opt for eco-friendly transportation and energy-efficient practices in order to lower emissions.  Examples include driving a battery-electric car and utilizing public transportation. 

Get Involved In Conservation Advocacy.  Support and engage in environmental causes, and help promote conservation and sustainable practices. 

As we ring in the new year, let’s raise our glasses to a cleaner and greener 2024.

The Spooky Reality | Earth Wise

By Leave a Comment

According to the National Retail Federation, American consumers will spend a whopping $12.2 billion on Halloween this year, exceeding last year’s record of $10.6 billion.  A record number of people – 73% of Americans – will also participate in Halloween-related activities this year, up from 69% in 2022.  But it’s not just our wallets that take a beating. 

Halloween generates a frightening amount of waste.  Picture all those flimsy and often single-use costumes, polyester cobwebs, plastic-wrapped candy, mass-produced decorations, and so forth. Scary stuff!  Here are some simple tricks to make the holiday more sustainable this year. 

Invest in quality costumes.  Those mass-produced costumes leave the largest carbon footprint from Halloween.  They are often made from non-recyclable plastic and most end up in landfills by mid-November.   By renting, thrifting, swapping, or making your own costumes, many of the negative impacts of dressing up for the holiday can be avoided.

Find environmentally-friendly decorations and supplies.  For example, carve local pumpkins and either save the seeds and flesh to eat later, compost it, or feed it to animals.  Make your own spooky decorations.  If you do buy decorations, ensure that they are durable and reusable.  And use wicker baskets, old bags, or pillowcases when trick-or-treating.

Finally, purchase organic and fair trade candy if you’re able to do so.  Some of the largest candy manufacturers are major drivers of deforestation and species extinction around the globe due to their demand for sugar, palm oil, and cocoa beans.

Together, we can “green” Halloween.

Wealth And Greenhouse Gas Emissions | Earth Wise

By Leave a Comment

A new study led by researchers from the University of Massachusetts Amherst has found that the wealthiest 10% of Americans are responsible for a staggering 40% of the country’s greenhouse gas emissions. The study, which was recently published in the journal PLOS Climate, is the first to link income, especially income derived from financial investments, to the emissions used in generating that income.

The research team suggests that policymakers adopt taxation strategies focused on shareholders and the carbon intensity of investment incomes in order to meet the global goal of limiting temperature rise to 1.5 degrees Celsius.

Historically, environmental policies have focused on regulating consumption, but the researchers argue that this approach misses something important:  carbon pollution generates income, but when that income is reinvested into stocks, rather than spent on necessities, it isn’t subject to a consumption-based carbon tax.  Rather than focus on how emissions enable consumption, they argue that the focus should be on how emissions create income. 

After analyzing 30 years of data, the researchers found that not only are the top 10% of earners in the United States responsible for 40% of the nation’s total greenhouse gas emissions, but that the top 1% alone account for 15-17% of the emissions. Emissions tended to peak in the 45-54 age group before declining.

The researchers highlight the need for an income and shareholder-based taxation strategy to incentivize climate action among high-income earners and industries, which could expedite decarbonization efforts and create tax revenue to support other climate initiatives.

Big Oil And Big Lithium | Earth Wise

By Leave a Comment

The world’s big oil companies have worked pretty hard to prolong society’s dependence on petroleum.  When there are trillions of dollars at stake, there is plenty of motivation.  But those companies do see the writing on the wall.

An Exxon Mobil-funded study last year estimated that light-duty vehicle demand for combustion engine fuels could peak in 2025 and that electric vehicles of various types could grow to more than 50% of new car sales by 2050.  This is pretty pessimistic compared with most other surveys, but it is still a big number.  Exxon also projected that the global fleet of EVs could reach 420 million by 2040.

As a result of all this, Exxon is preparing for a future far less dependent on gasoline by drilling for lithium rather than oil.  The company recently purchased mining rights to a sizable chunk of Arkansas land for over $100 million from which it aims to produce lithium for electric car batteries.

Exxon’s consultants estimated that the 120,000 acres in the Smackover formation of southern Arkansas could have as much as 4 million tons of lithium carbonate, enough to power 50 million cars and trucks. 

Exxon plans to spend $17 billion through 2027 on cutting carbon emissions and developing low carbon technologies.  Other large oil producers have also been looking at the lithium business.  At the same time, some large oil companies like BP and Shell are investing in renewable energy.

The prospect of EVs dominating transportation in the coming decades is a strong incentive for oil-and-gas companies to adapt their businesses to the new world.

Greening Halloween | Earth Wise

By Leave a Comment

According to the National Retail Federation, Halloween participation is expected to return to pre-pandemic levels this year.  Spending on Halloween festivities by the 69% of Americans who celebrate is expected to add up to $10.6 billion in 2022 – or more than $100 per person – reaching a new record high. 

Halloween generates a mind-boggling amount of waste.  Picture all the flimsy single-use costumes, plastic candy wrappers, mass-produced decorations, and so on.  Here are some tricks to treat you to a greener holiday.

Our first trick is to invest in quality costumes.  Mass-produced (and often single use) costumes leave the largest carbon footprint from Halloween.  They are often made from unsustainable materials, manufactured in countries with poor labor standards, and too many end up in landfills by mid-November. By renting, thrifting, swapping, or making your own costumes, many of the negative impacts of dressing up for the holiday can be avoided.

Our second trick is to invest in environmentally-friendly decorations and supplies.  For example, carve local pumpkins and save the seeds and flesh to eat later.  Make your own spooky decorations.  If you do buy decorations, ensure that they are durable and reusable.  And use a wicker basket, old bag, or pillowcase to trick-or-treat.

Our third trick is to pass out organic and fair trade candy.  Some of the largest candy manufacturers are major drivers of deforestation and species extinction around the globe due to their demand for sugar, palm oil, and cocoa beans.

If you’ve already spent your $100 this year, consider these changes for next year.  It’s never too late to become a superhero.

Spending Habits And Carbon Emissions | Earth Wise

By Leave a Comment

According to a new Swedish study recently published in the Journal of Industrial Ecology, men spend their money on greenhouse gas-emitting goods and services, such as meat and fuel, at a much higher rate than women. 

The study looked at the carbon emissions created by consumption among categories like food, clothing, furniture, and vacations to see if households could reduce their greenhouse gas emissions by buying different products and services.  The research team reviewed Swedish government data through 2012 and analyzed the spending habits of households, single men, and single women. 

According to the study, single Swedish men spent about 2% more money overall than single Swedish women.  But the stuff that the men bought created 16% more greenhouse gases than the stuff that the women bought.  That’s because men were more likely to spend money on high-emitting categories, like fuel for cars, while women spent more on less-emitting categories like furniture, health care, and clothing. 

For both men and women, vacations were a major source of emissions, accounting for approximately one-third of their total carbon footprint. 

While the carbon impact of men’s and women’s diets were nearly equal, men spent more money on meat while women spent more on dairy.  Both meat and dairy production are major sources of global greenhouse gas emissions.   

The study found single people were responsible for more greenhouse gas emissions than married people or people in households. 

According to the research team, people could decrease their carbon emissions nearly 40% by making more environmentally-friendly choices, including switching to plant-based foods and traveling by train as opposed to flying or driving when possible.

Renewable Energy And The Post-COVID World | Earth Wise

By Leave a Comment

As is the case for virtually all sectors of the global economy, the short-term prospects for wind and solar power look pretty grim.  Lockdowns, social distancing requirements, and financial upheavals have put many new projects on ice and have halted production at factories making solar panels and wind turbines.  Sales of home solar have struggled as people have put off spending during the economic slowdown.

Ironically, the shutdowns aimed at reducing the spread of the Coronavirus have led to renewable sources accounting for an increased share of power generation.  Global energy demand has plummeted and, because of the low cost of solar and wind power, sources like coal and nuclear power have been curtailed in favor of the renewables.  The dramatically reduced demand has pushed oil and gas prices to historic lows and has left fossil fuel companies struggling to find storage space for the glut of product.

When the world emerges from the pandemic, the question is whether renewable energy will end up on a faster track than before or will end up in a long-term slowdown.  The answer will depend to large extent on the choices political leaders make.

Leaders will unquestionably be designing economic recovery packages.  Such packages could accelerate the shift towards wind and solar power, or they could prop up the fossil fuel economy.  Unfortunately, leaders are prone to be motivated by lobbyists more than by the greater needs of society.  The global economic upheaval represents a real opportunity to change the pace of efforts to address climate change.  Whether that change is a positive one or a negative one is just another looming question facing society when we emerge from the pandemic.

Which Cities To Save From The Changing Climate

By Leave a Comment

After several years of brutal flooding and hurricanes in the U.S., a distressing debate is emerging:  if there is not enough money available to protect every coastal community from the effects of global warming, how do we decide which ones to save first.

Recent research looked at the costs involved in providing basic storm-surge protection in the form of sea walls for all coastal cities with more than 25,000 residents.  That number was $42 billion.  Expanding the list to include communities smaller than 25,000 people would increase that cost to more than $400 billion.   Realistically, that is just not going to happen.

This particular study only looked at sea walls and no other methods for minimizing flood risk, such as moving homes and businesses away from the most flood-prone areas.   It also didn’t look at additional and costlier actions that will be required even with sea walls, such as revamping sewers, storm water, and drinking water infrastructure.

The facts are that many cities, especially small ones, will not be able to meet the costs facing them.  Those that can’t will depend on federal funding.  But even optimistically large proposals for federal infrastructure spending are likely to fall far short of the vast need.  Ultimately, the money will end up being spent where it can do the most good – even if it means that some places are left out.

But what criteria will be used to direct the money?  Economic value?  Historic significance?  Population?  Political influence?

This is a looming and massive issue whose chief obstacle may be that many officials refuse to acknowledge that it is happening.  This is the next wave of climate denial – denying the costs that we are all facing.

Schools And Solar Power

By Leave a Comment

A new study from Stanford University looked at the benefits of installing solar panels on the rooftops of schools.  According to the study, taking advantage of all the viable space for solar panels could allow schools to meet up to 75% of their electricity needs and reduce the education sector’s carbon footprint by as much as 28%.

Given the long list of spending priorities for schools, solar power seems like a luxury item.  But the Department of Energy estimates that K-12 schools spend more than $6 billion a year on energy and, in many districts, energy costs are second only to salaries.  In the higher education sector, yearly energy costs add up to more than $14 billion.  In total, educational institutions account for approximately 11% of energy consumption by U.S. buildings and 4% of the nation’s carbon emissions.

The Stanford study suggests that investments in the right solar projects combined with the right incentives from states could free up much-needed money in school budgets.

To no surprise, the study finds that three large, sunny states – Texas, California, and Florida – have the greatest potential for generating electricity from solar panels on school rooftops.

Apart from measurable effects on air pollution and electricity bills, solar installations at schools can also provide new learning opportunities for students.  In fact, some schools are already using data from their on-site solar energy systems to teach students basic ideas about fractions, as an example, as well as more sophisticated concepts such how shifting solar panel angles can affect power production.

According to the study, nearly all states could reap value from school solar projects.
