Fake Meat And Climate | Earth Wise

March 10, 2023 By EarthWise 1 Comment

Investors have poured billions of dollars into efforts to replace animal proteins with plant-based substitutes or even laboratory-grown animal cells.  Replacing meats with these products is certainly a favorable development for the climate, but it is not likely to offset livestock agriculture’s climate and land use impacts anytime soon.

According to research at Stanford University, even optimistic estimates are that only something like 5% of dietary protein will come from these technologies by 2030.  That just isn’t fast enough to put a real dent in the food-related emissions problem.

Stanford environmental scientist David Lobell suggests that there should be much more focus on reducing emissions of animal-based systems.  There really hasn’t been much effort in this area because it is only recently that the climate impact of animal agriculture has been a topic of public concern.  One problem is that it is difficult for investors to monetize investments in approaches for lowering animal agriculture emissions.  These might include alternative feeds or supplements or vaccinations that inhibit methane-producing microorganisms in animals’ digestive systems.

Another approach to the problem is changing the mix of animal proteins in people’s diets.  Chicken and pork are half as bad as dairy per pound of protein, and about one-tenth as bad as beef, in terms of emissions.

Dairy is a major issue. There has been quite a lot of progress in increasing the use of dairy-free milk, but over the past 40 years, Americans have cut their consumption of milk in half but doubled their consumption of cheese.  Progress in dairy-free cheese has not been anywhere near as successful as that of dairy-free milk.  But new products are entering the marketplace all the time.

Are Companies Really Reducing Emissions? | Earth Wise

December 21, 2022 By EarthWise Leave a Comment

Many companies around the world are declaring tremendous progress in reducing their greenhouse gas emissions.  Sometimes these claims are the result of actions that really do  reduce emissions but other times they are the result of something called “market-based accounting”. Businesses buy credits from clean energy providers that allows them to say they are running on green power when they actually are not.

The market analysis firm Bloomberg Green analyzed almost 6,000 climate reports filed by corporations last year and found that over 1,300 of them employed market-based accounting to erase over 120 million tons of emissions from their records.

Some clean energy contracts do have major climate benefits.  For example, companies like Amazon, Nestle, and Target have signed long-term power purchase agreements that ultimately help renewable developers finance new energy projects.

On the other hand, renewable energy credits are often short-term transactions with existing facilities and do little to stimulate investment or otherwise lead to greater use of green power.  They simply shift around ownership of existing renewable energy without doing anything new for the climate.

Some companies have made meaningful cuts to their pollution by putting solar panels on their roofs, upgrading their lighting and air conditioning equipment, and so on.  But many are reluctant to spend their capital in this way, even if it eventually saves money through lower electric bills.

Customers and shareholders want to see corporations do their part in reducing emissions.  But too many are making grandiose claims enabled by market-based accounting while doing far too little to help the environment.  Dubious claims of climate progress are not harmless; it is essential for the world’s companies to really do their share.

Progress On Artificial Photosynthesis | Earth Wise

August 8, 2022 By EarthWise Leave a Comment

Photosynthesis is the process by which plants use the energy from sunlight to turn water and carbon dioxide into biomass and ultimately the foods we and other organisms eat.  Scientists at the University of California Riverside and the University of Delaware have found a way to create food from water and carbon dioxide without using biological photosynthesis and without needing sunlight.

The research, recently published in the journal Nature Food, uses a two-step electrocatalytic process to convert carbon dioxide, electricity, and water into acetate, which is the primary component of vinegar.   Food-producing microorganisms then consume the acetate in order to grow.   Solar panels are used to generate the electricity to power the electrocatalysis.  The result is a hybrid organic-inorganic system that is far more efficient in converting sunlight into food than biological photosynthesis.

The research showed that a wide range of food-producing organisms can be grown in the dark directly on the acetate output of the electrolyzer.  These include green algae, yeast, and the fungal mycelium that produce mushrooms.   Producing algae with this technology is about 4 times more energy efficient than growing it with photosynthesis.  Yeast production is about 18 times more energy efficient than the typical method of cultivating it using sugar extracted from corn.

Artificial photosynthesis has the potential to liberate agriculture from its complete dependence on the sun, opening the door to a wide range of possibilities for growing food under the increasingly difficult conditions imposed by the changing climate.

A Geoengineering Research Plan | Earth Wise

July 22, 2022 By EarthWise Leave a Comment

The 2022 federal appropriations act, signed into law in March, directed the Office of Science and Technology Policy to develop a cross-agency group to coordinate research on climate interventions, in partnership with NASA, the National Oceanic and Atmospheric Administration, and the Department of Energy.

The group is tasked with creating a research framework to “provide guidance on transparency, engagement, and risk management for publicly funded work on solar geoengineering research.”  The group is supposed to develop a five-year plan that will define research goals for the field, assess the potential hazards of climate interventions, and evaluate the level of federal funding required to carry out the work.

This marks the first federally coordinated effort of this kind and is especially significant because it contributes to the perception that geoengineering is an appropriate and important area of research as the climate continues to warm.

It is an understatement to say that such research is controversial.  Geoengineering has often been a taboo topic among scientists. There are significant questions about potential environmental side effects and concerns that the impact of any such efforts would be felt unevenly in different parts of the world.  There are challenging questions about global governance , including who should be able to make decisions about any potential deployment of climate interventions and what the goals of such interventions should be.

These are momentous issues to grapple with, but as the threat of climate change grows and nations continue to fail to make rapid progress on emissions, researchers, universities, and nations are increasingly motivated to seriously explore the potential effects of geoengineering approaches.  We can’t hide from the fact that these issues are going to be explored.

Five States Stepping Up On Clean Energy | Earth Wise

February 7, 2022 By EarthWise Leave a Comment

Five states step up climate action

While Congress continues to face partisan gridlock on climate issues, many states have moved forward with climate action.

In 2021, five states – Illinois, Massachusetts, Oregon, North Carolina, and Rhode Island – passed laws requiring a shift to 100% carbon-free electricity or net-zero emissions.  Washington State passed a law that helps to implement its strong 2019 and 2020 climate and clean energy laws.  Washington’s new legislation establishes a carbon trading program that will help the state to meet its goals of economy-wide emission cuts and 100% carbon-free electricity.

Several other states made progress on climate and clean energy by taking targeted actions not quite as aggressive as 100% laws, but significant, nonetheless.

The five states that entered the so-called 100% club joined with the six states that had earlier passed such legislation.  Those are California, Hawaii, New Mexico, New York, Virginia, and Washington.  Both Puerto Rico and Washington D.C. are also members of the club.

The past year may well be the biggest year yet for significant clean energy legislation.  Some of the states that finally passed laws had been gearing up for it for years.  This is particularly true of Massachusetts and Illinois.

Actions by individual states are not an antidote to inaction by the federal government, but they help.  At this point, about one-third of the country’s population lives in states that have laws requiring a transition to 100% carbon-free electricity, 100% renewable electricity, or net-zero emissions. 

All of this activity began in 2015, when Hawaii passed its renewable energy law.

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.

Progress Towards Carbon-Free Power | Earth Wise

June 3, 2021 By EarthWise Leave a Comment

Making progress towards carbon-free power

Climate change has driven countries, states, utilities, and corporations to set goals to eliminate power-sector carbon emissions.  So far, 17 U.S. states plus Washington, D.C. and Puerto Rico have adopted laws or executive orders to achieve 100% carbon-free electricity over the next couple of decades.  Forty-six U.S. utilities have pledged to go carbon-free no later than 2050.   Adding these together, these government and industry goals cover about half of the U.S. population and economy.

New research from the Lawrence Berkeley National Laboratory has analyzed historical trends to determine how much progress the power sector has already made in reducing emissions.  The study focused on the 2005 Annual Energy Outlook from the U.S. government’s Energy Information Administration.

If the previous growth in emissions had continued from 2005 to 2020, annual CO2 emissions would have risen from 2,400 to 3,000 million metric tons.  But actual 2020 emissions fell to only 1,450 metric tons.  So, by this metric, the U.S. power sector cut emission by 52% below projected levels.

According to the study, total consumer electricity costs were 18% lower than projected values, but meanwhile, the number of jobs in electricity generation was 29% higher. 

Among the driving forces for these trends were wind and solar power dramatically outperforming earlier expectations, delivering 13 times more generation in 2020 than projected. 

The study shows that dramatic changes in emissions are possible over a 15-year span, but much has to happen over the next 15 years to ensure the progress required to meet the ambitious goals set for emissions reductions.

Understanding How To Enhance Desalination | Earth Wise

February 16, 2021 By EarthWise Leave a Comment

How to improve desalination

Desalination is the process of removing mineral components – notably salt – from saline water, generally seawater.  Over 16,000 desalination plants operate across 177 countries, generating 25 billion gallons of fresh water each year.  Currently, desalination accounts for about 1% of the world’s drinking water.

The leading process for desalination in terms of installed capacity as well as new installations is reverse osmosis that makes use of a thin-film composite membrane based on ultra-thin polyamide.

Despite the fact that these membranes are widely used for desalination, they are actually rather poorly understood.  It has not been known exactly how water moves through them.  As a result, much of the progress made on the technology over the decades has been essentially based on guesswork.

A team of researchers at the University of Texas, Austin has used advanced microscopy techniques to solve some of the mysteries of reverse osmosis membranes.  By mapping membranes at very high resolution – less than half the diameter of a DNA strand – they gained a much better understanding of what makes a membrane better at reverse osmosis.

They found that desalination membranes are inconsistent in mass distribution and density and that these inconsistencies can impair membrane performance.  It turns out that inconsistencies and dead zones in membranes play a bigger role than membrane thickness.  By making the membranes more uniform in density at the nanoscale, they were able to increase desalination efficiency 30 to 40 percent, therefore cleaning more water with less energy and at lower cost.

Producing fresh water is not just essential for public health, it is also crucial for use in agriculture and energy production.

Positive Tipping Points And Climate | Earth Wise

February 15, 2021 By EarthWise Leave a Comment

Tipping points that could help mitigate climate change

A tipping point is a moment when a small change triggers a large and possibly irreversible response.

There has been much discussion of various tipping points that could accelerate climate change in catastrophic ways.  A recent paper from researchers at the University of Exeter in the UK discusses a couple of tipping points that could accelerate positive progress on mitigating climate change.

Electric vehicles account for only 2-3% of new car sales globally. In Norway, this figure is more than 50%, mostly thanks to policies that make electric cars the same price to buy as conventional cars.   According to the Exeter study, when EVs cost the same to manufacture as conventional cars, it will be a global tipping point.  China, the EU, and California together are responsible for half of the world’s car sales and each of these has targets to rapidly decarbonize their economies and policies in place to speed the transition to electric vehicles. 

Decarbonizing electric power is the other potential positive tipping point.  In Europe, carbon taxes on top of increasing renewable energy generation have tipped coal into unprofitability as they have led to the irreversible destruction of coal plants.  Globally, renewables are already generating electricity cheaper than fossil fuels in many countries.  Decarbonizing global power generation would in turn help accelerate decarbonization of large parts of transportation, heating and cooling, and industry.

These potential positive tipping points are by no means inevitable.  Appropriate policies are needed to overcome various barriers to the clean energy transition.  But major changes in transportation and electric power would have a tremendous impact on the global effort to combat climate change.

More Solar And Wind Power In The U.S.

January 2, 2020 By EarthWise Leave a Comment

According to the U.S. Energy Information Administration, both wind and solar power are contributing more and more to total electrical generation in the United States.  For the first 8 months of 2019, the combination of wind and solar power accounted for almost 10% of U.S. electrical generation.

Solar, including small-scale PV systems on home rooftops, grew by almost 14% compared to the first eight months of 2018 and accounted for more than 2.7% of total electrical output.  In fact, small-scale solar generation increased by 19% and provided nearly a third of all the solar power in the country. 

Wind energy in the U.S. increased by 4.4%, accounting for almost 7% of the country’s electricity.

Overall, renewable energy sources – which include biomass, geothermal, hydropower, solar, and wind – accounted for 18.49% of net domestic electrical generation during the first 8 months of 2019.  The non-hydro renewable sources actually accounted for over 11% of total electricity production and saw a year-over-year growth of 6%. 

Outside of renewables, nuclear-generated electricity declined by 0.6% and coal power dropped by almost 14%.  Much of the coal generation was replaced by natural gas, which grew by 6.5% compared to the previous year.

Renewables now accounting for nearly 20% of overall electricity generation in the US represents significant progress.  But the variations by state continue to be substantial.  For example, while Vermont gets 99% of its power from renewables, Ohio gets only 2%.

Amazon And Climate Change

October 30, 2019 By EarthWise Leave a Comment

Online shopping giant Amazon has unveiled a Climate Pledge, committing to meet the goals of the Paris climate agreement ten years ahead of schedule, and to be carbon neutral by 2040. This is the company’s most ambitious push yet to reduce its carbon footprint, which currently rivals that of a small country.  In fact, Amazon is responsible for 48.9 million tons of carbon dioxide last year, which is about 85% of what Switzerland typically emits in a year. 

Amazon, which ships more than 10 billion items a year on fossil fuel-intensive planes and trucks, has ordered a fleet of 100,000 electric vans that will start delivering packages to doorsteps in 2021.  The vans will be made by Rivian, a Michigan-based company that Amazon invested in earlier this year. 

Amazon plans to get 100% of its energy from solar and other renewable sources by 2030.  Currently, it gets about 40% of its energy from renewables. 

Amazon is also investing $100 million in nature-based climate solutions and reforestation projects around the world in order to remove carbon from the atmosphere. 

While announcing these initiatives recently at the National Press Club in Washington, D.C., Amazon CEO Jeff Bezos said the company needs to be a leader on the climate change issue:

We want to say look, if a company of Amazon’s complexity, scale, scope, physical infrastructure, delivering 10 billion items can do this, so can you.

After revealing Amazon’s Climate Pledge, Bezos said he would talk with CEOs of other large companies to try to get them to also sign it.  You can find a link to Amazon’s progress on its commitments by visiting this website.

Another Bad Year For Bees

August 6, 2019 By EarthWise Leave a Comment

The latest annual nationwide survey of beekeepers in the US revealed that honeybees are still dying off at an alarming rate.  According to the survey, beekeepers across the country lost 40.7% of their honey bee colonies from April 2018 to April 2019. 

This annual loss represents a slight increase over the average annual loss of 38.7%.  Of greater concern is that winter losses of 37.7% were the highest reported since these annual surveys began 13 years ago and are almost 9% higher than the survey average.

These results are very troubling considering that the elevated losses are continuing even after a decade of intense work trying to understand and reduce colony loss.  Evidently, there has not been much progress.

The number one concern among beekeepers is varroa mites, which are lethal parasites that can readily spread from colony to colony.  These mites have been decimating bee colonies for years.  Products developed to remove mites seem to be getting less and less effective.

But mites are not the only problem for bees.  Land use changes have resulted in reduced availability of pollen sources for bees.  Add to that pesticide exposures, environmental factors, and even problems with beekeeping practices.   In addition, extreme weather conditions such as wildfires and floods are only adding to the problems facing bees.

The tools that used to work for beekeepers seem to be failing and they are already stretched to their limits trying to keep their bees alive. Honey bees pollinate $15 billion worth of food crops in the United States each year. The problems facing bees are a problem for all of us.

Another Way To Make Solar Cells

March 21, 2019 By EarthWise Leave a Comment

Millions of rooftops now contain solar panels and the majority of the solar cells that make up those panels today are made from silicon.  Silicon solar cells require expensive, multi-step processing conducted at very high temperatures in special clean room facilities.  Despite these complications, the price of solar panels has continued to drop dramatically over the years.

But even as the price of solar cells gets lower and lower, there are still widespread efforts to find even better ways to make them.   One of those ways is with perovskite solar cells.  Perovskites are materials with a characteristic crystal structure and are quite common in nature.  Perovskites can be formed with a wide range of elements and can exhibit a variety of properties.

They were first used to make solar cells about 10 years ago and those first cells were unimpressive in most respects.  However, there has been steady progress since that time.  The potential advantages of perovskite solar cells are that they can be made from low-cost materials and can be manufactured using liquid chemistry, a far cheaper process than what is used to make silicon cells.

Researchers at MIT and several other institutions have recently published the results of research on how to tailor the composition of perovskite solar cells to optimize their properties.   What used to be a trial-and-error process can now become much more engineered and should lead to perovskite solar cells with performance that could exceed that of silicon cells.

Silicon solar panels are a huge, worldwide industry and displacing them in favor of an alternative technology is a tall order.  But if perovskite cells can be optimized for large-scale manufacturability, efficiency and durability, they could definitely give silicon a run for its money.

Misconceptions About Electric Cars

February 8, 2019 By EarthWise Leave a Comment

Tesla’s Model 3 was one of the best-selling cars in the United States last year, eclipsing all but a handful of sedans.  This was the first time that an electric car had that honor and is indicative of how electric cars are finally becoming mainstream.  A host of other new electric models from multiple manufacturers will be the entering the market over the next couple of years.

Despite all of this progress, there is still a great deal of misinformation about electric cars.  A new study commissioned by Volkswagen revealed some of the widespread misconceptions about the vehicles.

Some people believe that electric cars can’t be driven through puddles.  Nearly one in five people believe that electric cars slow down as the battery depletes.  Many people believe that electric cars are fundamentally less safe than gas-powered cars.

More generally, people are unaware of how far current electric cars can drive on a charge.  More and more models can go 200 and even over 300 miles between charging sessions.  People also don’t know how quickly cars can charge up either.  Fast chargers like Tesla’s Superchargers can add 200 miles worth of charge in about 20 minutes.  And people don’t know what it costs to charge electric cars.  In most places, it is only a fraction of what it costs to drive the same distance using gasoline.

Despite their limited knowledge about electric cars, the 2,000 people surveyed in Britain were positively disposed towards them with nearly 6 in 10 saying that they would like to own an electric car some day and would even consider one as their next vehicle.

Electric cars will become more familiar and less exotic as more and more of them are on our roads and highways.

As low-cost solar and wind energy become increasingly pervasive, the prospects for hydrogen-based transportation systems are improving.  The reason is that cheap electricity makes it practical to produce hydrogen by breaking down water rather than getting it from reforming natural gas, which results in carbon dioxide emissions.  The real goal is for hydrogen to be a renewable and carbon-free fuel.
