Massachusetts And Energy Policy | Earth Wise

By Leave a Comment

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.

Global Emissions And The Coronavirus Shutdown | Earth Wise

By Leave a Comment

With so much of industry and personal activity curtailed by coronavirus shutdowns across the globe, it is no surprise that greenhouse gas emissions have declined.  According to new research published in the journal Nature Climate Change, average daily global greenhouse gas emissions declined 17% by early April compared to 2019 levels.

If the reopenings around the world continue and the world actually reaches pre-crisis levels by the middle of June, total CO2 emissions for the year would likely end up lower by about 4%.   If various restrictions continue until the end of the year, total global emissions could decline by 7%.

The study analyzed emissions estimates for three levels of coronavirus shutdowns and across six sectors of the economy.  It looked at trends in 69 countries, all 50 U.S. states, and 30 Chinese provinces, representing in total 86% of the world’s population and 97% of global CO2 emissions.

For the first 4 months of the year, emissions from industry declined 19%, the power sector 7%, and public buildings and commerce 21%, compared to last year.  Unsurprisingly, home energy use actually went up by about 3%.

The findings of this study only represent the effects of a short-lived decline in emissions.  As economies open back up, there is no doubt that greenhouse gas emissions will rise back to pre-Covid-19 levels.

The study also reveals that making real changes in emissions will require more than just behavior changes.  Despite billions of people staying home, companies shut down, planes grounded, and cars off the road, we still managed to pump more than 80% of the usual amount of greenhouse gases into the air for the first quarter of the year.

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.

Metal From Plants | Earth Wise

By 2 Comments

Large amounts of metal in soil are generally bad for plants.  But there are about 700 species of plants that thrive in metal-rich soils.  These plants don’t just tolerate minerals from soil in their bodies but actually seem to hoard them to ridiculous levels.

In areas where soils are naturally rich in nickel, typically in the tropics and Mediterranean basin, plants have either died off or have adapted to become nickel loving.  Slicing open a tree with this adaptation produces a neon blue-green sap that is actually one-quarter nickel, which is far more concentrated than the ore that typically feeds commercial nickel smelters.

A group of researchers from the University of Melbourne and other institutions is investigating whether this phenomenon is not just interesting but might also be of real commercial value.  They established a plot of land in a rural village in Borneo and have been harvesting growth from nickel-hyper accumulating plants.  Every six to twelve months, a farmer shaves off one foot of growth from these plants and either burns or squeezes the metal out.  After a short purification, they end up with about 500 pounds of nickel citrate, potentially worth thousands of dollars on international markets.

Phytomining – extracting minerals from hyper-accumulating plants – cannot fully replace traditional mining techniques.  But the technology could enable areas with toxic soils to be made productive and might allow mining companies to use plants to clean up their former mines and waste while actually collecting some revenue.

There are other plants that suck up cobalt, zinc, and similarly crucial metals.  With growing demand for metals, perhaps it is time to harvest them on the farm.

Companies Promise Climate Action | Earth Wise

By Leave a Comment

A growing number of major corporations are making promises on climate and the promises are getting more ambitious and for faster action.  More companies are disclosing their carbon emissions and more of those companies have emissions reduction targets. 

There has also been an acceleration in the rate at which companies set so-called science-based targets, which are specific, measurable carbon reduction goals that align the company with the Paris Agreement.  Among the hundreds of companies with such targets are Coca-Cola, Nike, Best Buy, Walmart, and Hilton Hotels.  According to one analysis, the number of Fortune 500 companies with concrete, ambitious carbon targets quadrupled in the past four year to 23%.

Environmental advocates have been pressuring companies for decades, but companies seem to be far more proactive now despite the fact that the U.S. government has largely dropped the ball on climate issues.

The reasons include the fact that the effects of climate change are becoming clearer to companies.  Wildfires, rising sea levels, droughts and other aspects of the crisis both make headlines and affect business operations.

Meanwhile, solar and wind energy have gotten significantly cheaper, making it more attractive for companies to shift away from fossil fuels.

At the same time, investors are increasingly asking companies to act on climate issues.  Consumers, employees, and the general public are increasingly demanding action and even children are adding to the pressure to act.

Making these commitments is one thing; following through on them and sticking to them is another.  There are real concerns that there is a great deal of green-washing going on among companies trying to project a favorable image.  In any case, if companies really want to lead on climate, they need to put their money where their mouths are.

Jet Fuel From Acetone | Earth Wise

By Leave a Comment

Acetone is a common organic solvent.  It is used to make plastic, fibers, drugs, and other chemicals.  It is commonly used by consumers as nail polish remover.  Acetone is a manufactured chemical, but it is also found naturally in the environment in plants, among other places. There are now companies that produce acetone entirely by fermentation of plant feedstocks, such as corn.

Researchers at Los Alamos National Laboratory have now developed a process by which acetone can be converted into a fuel additive that can improve the performance of petroleum-based jet fuel, providing both environmental and economic benefits.

The process takes biomass-derived acetone and converts it to isophorone, which they produce by a process called photochemical cycloaddition that creates more complex hydrocarbons.  They then use ultraviolet light to convert the isophorone into cyclobutane, which is a type of hydrocarbon with high energy density that is suitable for aviation fuel applications.

Acetone itself is quite volatile and is unsuitable for fuel applications.  It also cannot be added directly to any fuel supply since it can dissolve engine parts and o-rings.  Cyclobutane, on the other hand, is a safer and more energy-dense fuel that can be a replacement for additives that require high-pressure hydrogen treatment in their synthesis.  Currently, most hydrogen is produced by a process that generates carbon dioxide.  The new conversion process does not result in carbon emissions.

According to the Los Alamos researchers, their process can result in a domestically generated product that will provide environmental benefits, create domestic jobs, improve U.S. energy security, and further U.S. global leadership in bioenergy technologies.

China And Rare Earth Mining

By Leave a Comment

Rare earth elements are a crucial part of much of modern technology.  Everything from computers to X-ray machines and aircraft engines needs one or more rare earth elements for magnets, lenses, and other functions.  The world’s tech giants such as Apple, Huawei, and Tesla depend on suppliers of rare earths.

Rare earth elements are not actually rare, but they are very expensive to extract in ways that are not extremely harmful to the environment.  China has been a major source of these elements since its rare earth mining industry took off in the 1990s.  The removal of rare earths from the earth’s crust, using a mix of water and chemicals, has caused extensive water and soil pollution.

Today, concrete leaching ponds and plastic-lined wastewater pools dot the hills of Southeast China.  Large wastewater ponds sit uncovered and open to the elements in many places.  Landslides or barrier failures can spill contaminated contents into waterways or groundwater.

Local and federal officials in China have started to shut down illegal and small-scale rare earth mining operations and have embarked on a cleanup of polluted sites.  The rare earth mining cleanup operation is part of wider efforts across China to address severe problems of water, air and soil pollution.

China’s Ministry of Industry and Information Technology estimated that the cleanup bill for southern Jiangxi Province could amount to more than $5 billion.  Many environmental experts and local officials say that the cost of the cleanup should not be shouldered by the Chinese government alone, but also by the rare earth industry and the global companies and consumers that benefit from rare earth technology.  As rare earth mining efforts start up elsewhere around the world, it is important not to repeat the mistakes made in China.

Climate Change And The Bottom Line

By Leave a Comment

Large companies around the world are facing up to the fact that climate change could substantially affect their bottom lines within the next five years.  Shareholders and regulators have been applying pressure to companies to disclose the specific financial impacts they could face as the planet warms and companies are increasingly making those disclosures.

A non-profit charity called CDP (formerly known as the Carbon Disclosure Project) runs the global disclosure system for investors, companies, cities, states, and regions to manage their environmental impacts.  In 2018, more than 7,000 companies submitted reports to CDP and, for the first time, CDP explicitly asked firms to try to calculate how a warming planet might affect them financially.

Analysis of the reports from 215 of the world’s 500 largest corporations revealed that these companies alone potentially faced roughly $1 trillion in costs related to climate change in the decades ahead unless they took proactive steps to prepare. 

Climate-related risks range from extreme weather that could disrupt supply chains to stricter climate regulations that could hurt the value of coal, oil, and gas investments.  Technology companies like Google’s parent company, Alphabet, Inc., face increased costs to cool energy-hungry data centers as temperatures rise.

In all, the world’s largest companies estimated that at least $250 billion of assets may need to be written off or retired early as the planet heats up.  Previous studies, based on computer climate modeling, have estimated that the risks of global warming, if left unmanaged, could cost the world’s financial sector between $1.7 trillion to $24.2 trillion in net present value terms.

Climate Change And Insurance

By Leave a Comment

While there are still some people who remain dubious about the reality of climate change, insurance companies are not among them.  And, in fact, insurers are warning that climate change could make coverage for ordinary people unaffordable.

Munich Reinsurance, the world’s largest reinsurance firm, blamed global warming for $24 billion in losses from California’s recent wildfires.  Such costs could soon be widely felt as premium rises are already under discussion with insurance companies having clients in vulnerable parts of the state.

With the risk from wildfires, flooding, storms and hail increasing, the only sustainable option for the insurance industry is to adjust risk prices accordingly.  Ultimately, this may become a social issue.  Affordability of insurance is critical because if rates go up too much, many people on low and average incomes in some regions may no longer be able to buy insurance.

The great majority of California’s 20 worst forest fires since the 1930’s has occurred since the year 2000 driven by abnormally high summer temperatures and persistent drought. The reinsurance giant analyzed decades of data with climate models and concluded that the fires are likely driven by climate change.

It isn’t just wildfires.  Insurance premiums are also being adjusted in regions facing an increased threat from severe convective storms whose energy and severity are driven by global warming.  These include parts of Germany, Austria, France, southwest Italy, and the U.S. Midwest.

Linking extreme weather events to climate change is a bit like attributing the performance of a steroid-using athlete to drug use.  The connections are clearer in patterns than in individual disasters.  But the pattern these days is pretty clear.

Building For Climate Change

By Leave a Comment

The manifestations of climate change are creating increasingly familiar images:  floodwaters rising up house windows, charred buildings in the wake of wildfires, and homes and businesses demolished by storm winds. As these sorts of calamities become ever more common, changes to how houses are built are going to be necessary.

How can homes become more resilient against severe and unpredictable weather?

Research at Carlton University’s Sprott School of Business looks at this issue.

As an example, houses can be framed and finished in certain ways that help protect them from wind and flooding.  But such methods are currently only happening in the custom-build fringes of the housing sector.  Widespread adoption will require, at the minimum, significant changes to building codes.

Revising building codes is not an easy matter.  The codes themselves are highly technical and complex, and beyond that, the process Is often politicized.

Even simple things like hurricane ties, which are small pieces of hardware that prevent a roof from lifting during a severe wind are not now included in building codes.  Insurance companies support their use as inexpensive protection for houses.  But even though the overall cost is relatively minor, the building industry pushes back at the additional expense.

The need to reduce carbon emissions has created a push for sustainable housing.  But the increasingly erratic weather means that houses also need resilience and adaptation.  These features will inevitably add costs and incorporating them into building codes requires producing convincing business cases.

The U.S. experienced 394 natural catastrophe events last year costing $225 billion in damage.  Finding ways to make homes and businesses more resilient is not just a good idea; it is essential.

Bigger Is Better For Wind Energy

By Leave a Comment

Bigger is almost always better for wind power.  Bigger wind farms are better than smaller wind farms and bigger wind turbines are better than smaller ones.

The biggest turbines currently available produce nearly 10 MW of power, which is enough to supply over 2,000 homes with electricity.  A wind farm with just a few of these turbines could produce enough electricity for a small town.  A big wind farm, like the giant 1,550 MW Alta Wind Energy Center in California can generate enough power for a small city.

Vestas Wind Systems, an industry leader based in Denmark, has announced a 10 MW turbine that will be ready for installation in two years.  The rotor diameter of the giant machine is 538 feet and the blades sweep out an area of 227,000 square feet, the size of nearly 4 football fields.

Not to be outdone, General Electric is developing a 12 MW offshore wind turbine that will stand 850 feet tall and sweep out an area of more than 400,000 square feet.  GE estimates that its 12 MW turbine will achieve nearly twice the capacity factor of its 6 MW turbine.

Companies are building bigger and bigger wind turbines because they are more cost effective.  The capacity factor, which is the actual energy production divided by the potential energy production, goes up as the turbines get bigger and more efficient.  In terms of dollars spent to produce a given amount of power, larger windfarms are less expensive to build than smaller ones.  A wind farm of 200-500 MW capacity is about 40% cheaper per MW capacity than a 25 MW wind farm.

When it comes to wind energy, there is no doubt that bigger is better.

The Labeling Of GMO Foods

By Leave a Comment

American consumers will soon be able to discern whether or not foods contain genetically-modified ingredients.  The USDA’s so-called ‘National Bioengineered Food Disclosure Standard’ will be required for foods that have been altered in a way that doesn’t occur naturally. The mandatory compliance date is January 1st, 2022. 

While this does sound like great news, there are some major drawbacks.  The new guidelines use the uncommon term “bioengineered” instead of “genetically-modified” or “GMO.” The guidelines also allow the disclosure of bioengineered (or B.E.) ingredients in several formats: as text, a symbol, a phone number (that consumers can call for more info), or a digital link printed on the packaging.  Companies are allowed to use a QR code that asks consumers to “scan here for more food information.”  Scanning the QR code will bring consumers to a website where the GMO disclosure can be found. 

Advocates of the various labeling options say it’ll make it easier and faster for companies to comply with the new guidelines.  But critics worry consumers will find it confusing and restrict access for those without smartphones.  They say that companies who elect to use a QR code or phone number should be required to include the word “bioengineered” on their packaging.

Another drawback is that products won’t have to be labeled as ‘bioengineered’ if they’ve been processed to the point where their bioengineered DNA can’t be detected.  Examples include refined beet sugar, soybean oil, and high fructose corn syrup.  

The fight over the labeling of GMO foods has raged for many years.  But this labeling mandate falls short of consumer expectations by hiding the information about GMOs instead of disclosing it. We should expect better.

A Disastrous Year

By Leave a Comment

The number and economic impact of natural disasters around the world have increased dramatically over the past 30 years.  In dollar terms, the amount has actually more than doubled.  While 2017 and especially 2011 hold the records for worldwide economic damage, 2018 was pretty disastrous in its own right, totaling at least $160 billion.

The year was dominated by costly wildfires in California and tropical storms in the United States and Asia.   According to a recent report by the reinsurance company Munich Re, the Camp and Woolsey fires in California alone caused losses of $21.7 billion, $16.5 billion of which was insured.

Overall, insurance companies paid out $80 billion in damage claims from natural disasters last year.  This was less than the $140 billion in 2017 but is still double the 30-year average.

Losses from wildfires have increased dramatically in recent years and summers continue to get hotter and dryer, a likely consequence of climate change.  These mounting costs bring into question whether people can continue to build in high-risk wildfire areas without dramatic changes in materials and the aggressive use of other protective measures.

Twenty-nine natural disaster events in 2018 caused more than a billion dollars in damage each.  Tropical storms including hurricanes Michael and Florence in the United States and three Asian typhoons caused $57 billion in damage.

A severe drought in Europe that set off major wildfires and caused agricultural losses caused $3.9 billion in losses.  Only about $280 million of this damage was covered by insurance companies since farmers in Europe don’t typically purchase insurance against drought.  For them, 2018 was truly a disastrous year.

Energy Justice In California

By Leave a Comment

California put in place a cap-and-trade program in 2013.  In such a program, companies pay penalties if they exceed a cap in carbon emissions but can buy and sell allowances that permit them to emit a given amount. Trading gives companies a strong incentive to save money by cutting emissions.  Since taking effect, the California program has raised more than $6.5 billion and is the fourth largest in the world.

Cleaning Up Shipping Fuel

By Leave a Comment

Cargo ships are significant sources of global air pollution because of their fuel oil.  Most ships burn something called “bunker fuel” which is a pitch-black, molasses-thick fuel made from the dregs of the oil refining process.  It is loaded with sulfur, so when it is burned it produces noxious gases and fine particles that can harm human health and the environment.  Because bunker fuel is made from petroleum refining residues, waste byproducts sometimes end up in the mix, making the stuff even a worse source of pollution.
