Artificial intelligence and lost oil wells

January 2, 2025 By EarthWise Leave a Comment

There have been commercial oil and gas wells across the United States for 170 years. Researchers estimate that there are between two and three million wells that have been abandoned. There are hundreds of thousands of them, across 27 states, that are “orphaned,” meaning that they are uncapped, unproductive, and nobody is responsible to manage their leakage or pollution.

Many are undocumented orphaned wells – UOWs – that are not listed in formal records and are basically out of sight and out of mind. Besides having nobody responsible for them, nobody even knows where they are. But they are potential sources of oil and chemical leaks into nearby water sources and can send toxic substances like benzene and hydrogen sulfide into the air.

Researchers are using modern tools like drones, laser imaging, and advanced sensors to try to locate UOWs. But these wells are scattered over an area of more than three million square miles.

To better predict where to look for undocumented wells, researchers are combining historical topographic maps with artificial intelligence. The US Geological Survey has scanned 190,000 topographic maps made between 1884 and 2006. AI is being used to find the symbols for oil and gas wells on the maps. People can recognize these symbols easily, but there are just too many maps to look at. The problem is equivalent to finding a needle in a haystack; there is just an awful lot of hay to look through.

Abandoned wells are a big problem and it will take lots of modern technology to try to solve it.

Halloween pumpkins

October 28, 2024 By EarthWise 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.

Electric Cars And Apartments | Earth Wise

July 10, 2023 By EarthWise Leave a Comment

The transition to electric cars is underway. People are increasingly buying them, carmakers are switching over to making them, and governments are providing incentives as well as legislating the changeover. More and more consumers want to lower their carbon footprints and stop burning fossil fuels. But one very large group of consumers faces an uphill battle in switching to electric cars: people who rent their dwellings.

About one third of our country lives in rented apartments or houses. These nearly 110 million Americans are more likely to be in the bottom half of income and net worth and are more likely to be people of color. These people are less likely to have the spare cash to make upgrades to their property such as car chargers and may not be able to get permission from their landlords to do it anyway.

Renters face what is known as the “split-incentive problem” or the “landlord-tenant problem.” Three-quarters of tenants in the US pay their own utility bills, so they have a strong incentive to conserve electricity, water, and gas. Their landlords, on the other hand, have little incentive to upgrade appliances and systems to be more environmentally responsible. Studies have shown that on average renters use 3% more energy than homeowners for this reason.

There are some landlords who are being proactive and installing facilities for charging cars on their properties. This will undoubtedly become an increasingly sought-after feature for renters. But in the meantime, millions of them have a more difficult time driving electric cars. They can charge at public chargers or perhaps at work. But at the moment, homeowners are three times more likely than renters to own an electric car.

Phasing Out Disposables | Earth Wise

May 5, 2022 By EarthWise Leave a Comment

Humans generate a remarkable amount of garbage. According to the World Bank, humans produce 4.5 trillion pounds of trash every year, with at least 33% of this garbage not managed in an environmentally-safe manner. By 2050, global garbage generation is expected to reach nearly 7.5 trillion pounds a year.

Globally, an average of 1.6 lbs of waste is generated per person per day. While high-income countries only account for 16% of the global population, they are responsible for about 34% of the world’s waste.

But almost everything humans throw away was bought from a company. Whether it was the packaging or the product itself, we purchased it from somewhere. There’s a growing movement to hold the companies responsible for the trash they produce.

Faced with increasing consumer consciousness, many companies are stepping up and announcing initiatives to reduce their waste. Starbucks is one of them. The company’s white logo-emblazoned paper cups and clear plastic cups are instantly recognizable symbols of the brand. But these ubiquitous cups are disposable and also serve as a symbol of our throwaway society.

By the end of next year, Starbucks is planning to allow customers to use their own personal mugs at every location in the U.S. and Canada. By 2025, the company wants every customer to be able to use either their own mug or to borrow a ceramic or reusable to-go mug. This borrow-a-mug program is currently being tested in eight different markets around the globe.

In lieu of regulation mandating corporate responsibility for waste, we will have to hope that more companies do the right thing.

Not Such Climate Champions | Earth Wise

April 5, 2021 By EarthWise Leave a Comment

The goal of the Paris Climate Accord is to limit warming to below 2 degrees Celsius and if possible to stay as close as close to 1.5 degrees above pre-industrial levels. Nations around the world have made commitments to drastically reduce their carbon dioxide emissions from the use of fossil fuels that are in large part responsible for the rising temperatures.

There are a number of countries that proudly claim to be leading the world in the fight against climate change but who are actually still a major part of the problem. Among these are Norway, the UK, and Canada.

Norway powers its streetlamps with renewables, runs its public transportation system entirely by renewable energy, and leads the world in the adoption of electric cars. Both the UK and Canada have set ambitious targets for emissions reductions leading to zero net emissions by 2050.

The problem is that under the Paris Agreement, each country is only responsible for the greenhouse gas emissions produced within its territory. That means that the UK, Canada, and Norway (like many other countries) don’t need to worry about the emissions caused by the burning of their oil, gas, and coal in other places around the world.

Norway’s annual domestic emissions reached about 53 million tons in 2017 according to its government. The emissions from the oil and gas Norway sold abroad reached roughly 470 million tons in 2017. Canada has huge proven oil reserves it is exploiting.

Canada, Norway, and the UK all plan to keep producing fossil fuels, investing in new fossil fuel projects, and explorations. As long as this continues, these countries are not really climate champions; they are climate hypocrites.

Paying To Combat Climate Change | Earth Wise

November 2, 2020 By EarthWise Leave a Comment

The majority of Americans believe that climate change is happening, that human activities are largely responsible, and are actually willing to put up their own money to help fight it. Unfortunately, these views diverge sharply along party lines and, as in many other areas these days, the will of the overall majority has little influence on policy.

According to Yale University research, 73% of adults think that global warming in happening and 57% think it is mostly caused by human activities. Furthermore, only 32% believe it is due to natural forces.

A survey conducted in the U.S. in August found that more than two-thirds of Americans – actually 70% – indicated willingness to donate a percentage of their personal income to support the fight against climate change.

Breaking that down further, 28% were willing to provide less than 1% of their income, 33% were willing to contribute 1-5% of their income, 6% said they would give 6-10% of their income, and 3% said they would contribute more than 10% of their income. On the other hand, roughly 30% indicated that they were unwilling to contribute.

The survey also looked at opinions on how the fight against climate change should be paid for. The majority (59%) chose government incentives for both businesses and consumers. Three other options each favored by over 40% of those surveyed were taxes, conservation programs, and business investments.

Another finding of the survey was that 44% are dissatisfied with the job that the federal and state governments are doing to address climate change, 35% are somewhat satisfied, and only 21% are very or completely satisfied with the government’s role.

Lifestyle And Carbon Footprint | Earth Wise

March 23, 2020 By EarthWise Leave a Comment

Many studies have shown, to no great surprise, that affluent lifestyles lead to larger carbon footprints. Households in Switzerland enjoy a high standard of living and a team of researchers there has been studying the consumption and travel habits of Swiss citizens to better understand the impact of various factors on carbon footprint. Key factors include household composition and income, and whether the households are in the city or the countryside – even though, in the end, people’s lifestyles do not differ greatly from one environment to another.

A team of researchers at EPFL’s School of Architecture, Civil and Environmental Engineering analyzed data from Switzerland’s household budget survey for 2008, 2011 and 2014. They combined that data with an environmentally extended input-output analysis to assess households’ carbon footprints by measuring their direct and indirect emissions.

Overall, households in the countryside have larger carbon footprints than those in the city, mainly because they travel more and use more energy in their homes. But urban households have larger carbon footprints than their rural counterparts when it comes to food, clothing, cultural activities and air travel.

A household’s composition directly influences its carbon footprint. A two-person household has the largest per-capita carbon footprint, and it falls as the size of the family grows since many of the same resources are shared by more people.

Income levels play an important role. People consume without much thought because they can afford to and enjoy doing it. But there is a trend towards people becoming more conscious of their levels of consumption and trying to be more responsible in Switzerland. Overall consumption has actually declined over the years studied.

Minerals And Metals For A Low-Carbon Future | Earth Wise

February 14, 2020 By EarthWise Leave a Comment

For the past century, economies and geopolitics have largely been driven by our insatiable appetite for oil and fossil fuels in general. As we gradually make the transition to a low-carbon energy future, the focus on oil will shift to sustainable supplies of essential minerals and elements.

The use of solar panels, batteries, electric vehicle motors, wind turbines, and fuel cells is growing rapidly around the world. These technologies make use of cobalt, copper, lithium, cadmium, and various rare earth elements. The need for any one of these things may diminish if alternatives are found, but there will continue to be a growing reliance on multiple substances whose physical and chemical properties are essential to the function of modern devices and technologies.

In some cases, global supplies of particular minerals and elements are dominated by a particular country, are facing social and environmental conflicts, or face other market issues. Shortages of any of them could create economic problems and derail progress much as the oil-related energy crises of the past have.

The world faces challenges in managing the demand for low-carbon technology minerals as well as limiting the environmental and public health damage that might be associated with their extraction and processing. Expanded use of recycling and reuse of rare minerals will be essential.

As the relatively easy sources of these materials become exhausted, other resources will become more attractive. These include various valuable ecosystems, oceanic deposits, and even space-based reserves.

Ushering in the low-carbon future is not a simple matter and will require responsible actions by the world’s governments and industries. In undoing the damage from the oil age, we must avoid new damage from the low-carbon age.
