Snowmaking goes high-tech as ski resorts adapt to rapid melting.

by CharlesLarnach Posted on March 26, 2018

Producing artificial snow used to be a desperate move taken by ski areas within striking distance of surfing beaches. Now, the practice is commonplace, even high in the Rocky Mountains and the Alps.

As a headline in Powder Magazine read last year, “Like It or Not, Snowmaking Is the Future.”

Utah’s Alta ski area has doubled its snowmaking capacity in the last decade. To make sure all those big machines and water pipes don’t detract too much from the scenery, they’re painted to blend in with the background, according to a dispatch from Wired. At Snowbird, also in Utah, each snow gun has its own weather station, allowing the machines to start, stop, and adjust water flow all on their own.

California’s Squaw Valley spent $10 million on machines that automatically change their water pressure and amount several times a second. Heavenly Ski Resort, at Lake Tahoe, can cover 3,500 acres with fake snow.

All these machines run on electricity, which comes from the still-mostly-fossil-fueled grid. That means making fake snow increases the rate of The Great Melt, which in turn creates demand for … more snow machines. There’s a self-perpetuating cycle of job security for these snow-bots: Is this the way Skynet becomes self-aware?

Are Fuel Additives Really Green?

by GSCClarita Posted on March 26, 2018

Shares

As gas prices trend upward, you may be wondering about ways to maximize the fuel economy in your car. One commonly assumed option is adding a gasoline additive when you fill the tank, and there are plenty on the market.

In fact, it’s estimated the fuel additive market will reach over $11 billion by 2024, with environmental concerns one of the top reasons. This leads to the question: Are fuel additives actually eco-friendly?

What Is a Fuel Additive?

Simply put, fuel additives are products that will increase gasoline’s octane rating (so you can buy 87 octane and get the benefits of 89 or 91 octane) or help prevent engine corrosion. They have been around since 1970, when Chevron gas featured a new additive called polybutene amine, marketed as F-310.

F-310 was promoted as reducing emissions by up to 50 percent and increasing fuel economy by up to 7.7 percent. This product has eventually been modified into Techron, arguably the most recognizable fuel additive today.

For F-310, the Federal Trade Commission (FTC) investigated claims of deceptive advertising, and Chevron ended up pulling the campaign. Ever since, the FTC has kept tabs on how fuel additives promote their benefits to consumers.

This hasn’t stopped the market from developing. Because the Environmental Protection Agency (EPA) requires gasoline additive companies to register their products, we know that there are more than 10,000 fuel additives on sale today. Not surprisingly, over 100 have the word “green” in the company or product name.

How Are Additives Regulated?

The additive registration process does not include testing for fuel economy increases or emissions reductions, although manufacturers must include the chemical composition of additives. The EPA makes a point to say that even though a product is registered, that doesn’t imply an EPA endorsement of its benefits.

However, the EPA does have a voluntary testing program called the Evaluation Program for Aftermarket Retrofit Devices, where manufacturers allow their additives to be tested to verify marketing claims. So far, 92 fuel additives have been tested, most recently in 2005, and most have had either “a neutral or negative effect on fuel economy and/or exhaust emissions.”

For some companies, the FTC may step in and challenge claims. This was the case in 2013, when the manufacturer of EnviroTabs was fined $800,000 for stating its product increases fuel efficiency and reduces emissions.

When to Use Fuel Additives

While the jury is still out on improved fuel economy, there are a few areas where fuel additives have been shown to help your car:

  1. Fuel stabilizers can be used in seasonal vehicles (boats, RVs) or classic cars to preserve the gasoline over time.
  2. Fuel injection cleaners are helpful if most of a commute is via short trips where the engine doesn’t heat enough to burn off the carbon that accumulates over time.

Fuel additives have their place if your goal is to beat Vin Diesel in a drag race, but there isn’t much evidence that they will save you at the gas pump or produce fewer emissions. If that’s your goal, here are 11 free steps you can take while driving.

Lack of snowpack leaves the West hung out to dry

by RosieEddy4 Posted on March 13, 2018

The lack of snow across the West this winter points to a parched summer ahead.

In California, Colorado, and across the Southwest, the snowfall has ranked among the lowest on record. The last four months have also been among the warmest throughout most of the region, according to a report out last week. Parts of eight states already are already under “extreme” drought conditions.

Snowy, chilly winters are critical when it comes to recharging the West’s mountain snowpack, the source of water for rivers and reservoirs during the increasingly long and hot summer days. Less snow in the mountains, in other words, means less water for everybody living below.

“I don’t think it’s hyperbolic to say that this winter is the stuff of nightmares for water managers in the Colorado River watershed,” says Luke Runyon, a Colorado-based public radio reporter focusing on western water. Some 40 million people in seven states depend on water from the Colorado River, and at this point, spring storms across the river’s wide drainage area would need to produce snow at more than 300 percent of the typical rate just to get back to normal for the season.

In the river’s main storage spot, Lake Mead just south of Las Vegas, Nevada, water levels are on track to fall so low that they would trigger the first-ever official shortfall late next year, according to new data from the U.S. Bureau of Reclamation. Water rationing would be the next step.

Warmer, drier winters like this one are exactly what you’d expect with climate change. A new study published earlier this month showed that over the past 100 years, more than 90 percent of snow monitoring sites throughout the West have seen a decline in snowpack. In total, that’s a loss of summertime water storage equivalent to Lake Mead.

“It is a bigger decline than we had expected,” said Philip Mote, a climate scientist at Oregon State University and lead author on the study, in a statement. “In many lower-elevation sites, what used to fall as snow is now rain.”

The evidence of dwindling snowpack is nearly everywhere you look. According to the latest information from the National Oceanic and Atmospheric Administration, the period between Nov. 1 and Feb. 28 was at or near the warmest and driest on record for nearly every corner of the Southwest. In Arizona, the Navajo Nation has declared a drought emergency, and farmers across the West are preparing for a dry summer, contemplating killing livestock for fear they won’t be able to feed them later this year. Last week, a 23,000-acre wildfire popped up near the Colorado-New Mexico border, a striking example of just how dry things are right now.

In California, statewide snowpack on March 1 rivaled the lowest ever measured, just 19 percent of normal. A series of big storms have since nudged that value to about 37 percent of normal — a major win in a state where every drop counts. One problem, though: New data from the California’s Water Resources Control Board show that people are using more water after last year’s relatively good rains, as usage rates are back near where they were before the state’s five-year drought. It seems that many Californians have already forgotten what they learned about how to save water.

Faith Kearns, a water scientist at the California Institute for Water Resources, says the state is already planning on varying levels of shortfalls this summer. “It’s going to be another dry year,” she says. “Our reservoirs are in decent shape from last year’s storms, but we need to continue conserving.”

It’s clear that the West’s steady and transformative slide into a drier future has already begun. This is just the start.

Judge to Trump: You can’t just ignore pollution rules.

by rmcg7920021988 Posted on March 13, 2018

In Sheridan County, farmers managed to slash irrigation by 20 percent without taking a punch in the wallet, according to a new economic analysis.

The wells in Sheridan County sip from the Ogallala Aquifer, an underground lake that stretches from South Dakota to Texas. It happens to be rapidly depleting.

“I’d rather irrigate 10 inches a year for 30 years than put on 30 inches for 10 years,” farmer Roch Meier told Kansas Agland. “I want it for my grandkids.”

Compared to neighbors who didn’t cut back, Sheridan farmers pumped up 23 percent less water. While they harvested 1.2 percent less than their neighbors, in the end, they had 4.3 percent higher profits.

Using less water, it turns out, just makes good business sense. It takes a lot of expensive electricity to lift tons of water up hundreds of feet through the ground. The farmers frequently checked soil moisture with electronic probes, as Circle of Blue reports. They obsessively watched weather forecasts to avoid irrigating before rain. Some switched from soy to sorghum, which requires less water. Some planted a little less corn.

If farmers in western Kansas sign on and cut water use just a bit more (25 to 35 percent), it might be enough to stabilize the aquifer.

7 Laundry Hacks That Save Time, Money and the Planet

by MikelSlowik Posted on December 6, 2017

Shares

Laundry is a drain on the modern green household. It sucks up energy, water, and time — three things very precious to any eco-warrior. Fortunately, technology has some excellent solutions to our laundry problems. Here are seven laundry hacks that help you make sure your washer and dryer are doing their part for the planet.

1. Upgrade to an Energy Star Model

If your current washer and dryer are more than 10 years old, upgrading them will save you significant time doing your weekly laundry and also reduce your utility bills. Energy Star–rated washers can reduce your water use by 45 percent and your energy use by 25 percent. An Energy Star–rated dryer will save you around $245 in energy costs over its lifetime. If upgrading isn’t an option yet, be conscientious about using your current washer’s settings correctly. If you have water level settings, make sure to set your washer to the lowest one. If not, always use the correct load size setting — small for small loads, medium for medium loads, and so on. You could save more than 1,200 gallons of water per year.

2. Wash Your Clothes in Cold Water

Almost 90 percent of the energy a washer needs is used to heat water. If you wash your clothes in cold water, you’ll cut down your energy use significantly and save $66 or more a year on your energy bill, depending on the amount of laundry you do. New high-efficiency (HE) washers clean just as effectively with cold water. Make sure to use a specially designed HE laundry detergent.

3. Select the Fastest Spin Speed

Choose the fastest spin speed your washer (and your clothes) can handle. The faster the washer spins, the more water is whisked out of the load, and the less time it needs to spend in the dryer. Be sure to use this for towels, if nothing else.

4. Take Advantage of Sensor Features

Load and moisture sensors will intelligently adjust your washer and dryer cycles. Load sensing assesses each load you put in the washer and determines how much water is needed to clean it properly. Similarly, moisture sensors are more efficient than setting a timer on your dryer. These sensors can tell when your clothes are dry and stop the machine, reducing your dryer’s energy use by about 15 percent.

5. Opt for Models That Use Less Water

Traditional top-loading washing machines fill up the entire tub with water and rub clothes against the agitator in the middle of the tub. New top-loader models don’t have an agitator — they flip and spin clothes through a stream of water instead of filling the whole tub, which significantly reduces water usage. Front-loading washers tumble clothes to clean them instead of using an agitator. Either option is an eco-friendly choice that will reduce the amount of water you use to do laundry.

6. Turn Down the Dryer Heat

Longer drying cycles on a low heat setting use less energy. Be sure to clean the filter in between loads to keep the dryer in top working order.

7. Toss a Tennis Ball into the Dryer

This old-school trick really works. When you’re drying large, bulky items — such as down comforters, jackets, blankets or pillows — throw in a couple of new tennis balls with the load. The balls bounce around in the dryer to separate the waterlogged, heavy material, which reduces drying time and energy usage.

Follow these laundry hacks to take advantage of today’s washer and dryer features that save time, energy and water for a super-green laundry routine.

Flint’s mayor, who promised to clean up its water problems, faces a recall election today.

by LucretiG37 Posted on November 7, 2017

At a hearing on the federal response to the 2017 hurricane season, New York Congressman Jerrold Nadler questioned the EPA’s decision to declare water drawn from the Dorado Superfund site OK to drink.

In 2016, the agency found that water at Dorado contained solvents that pose serious health risks, including liver damage and cancer. Yet after CNN reported that Hurricane Maria survivors were pulling water from the site’s two wells, the EPA conducted an analysis and found the water fit for consumption.

When Nadler asked Pete Lopez, administrator for Region 2 of the EPA, why his agency changed its position, Lopez responded that the chemicals are present in the water, but are within drinking water tolerance levels.

The EPA’s standards for drinking water are typically higher than international norms, John Mutter, a Columbia University professor and international disaster relief expert, told Grist. Nonetheless, he believes it is unusual for the EPA to declare water safe to drink just one year after naming it a Superfund site.

At the hearing, Nadler said the situation was “eerily similar” to the EPA’s response after 9/11 in New York. One week after the attacks, the agency said the air in the neighborhood was safe to breathe. But since then, 602 people who initially survived the attack have died from cancer or aerodigestive issues like asthma, and thousands more have become sick.

“The [EPA’s] history of making mistakes makes you feel like perhaps they should be challenged,” says Mutter, citing the water contamination crisis in Flint, Michigan.
