Despite everything, U.S. emissions dipped in 2019

Just a week into the new year, and the first estimate of how much planet-cooking pollution the United States belched into the atmosphere last year is already in. It’s not the kind of report card you’d be proud to show your parents, but at least it won’t leave you in tears.

Perhaps surprisingly, total emissions fell 2 percent compared with the year before, according to the Rhodium Group, a research firm that frequently crunches climate numbers. The reason for that decline? The U.S. is burning less coal. That’s been driving down emissions from electricity generation. But the way we get around, heat our homes, and manufacture our stuff, hasn’t had much of an effect.

“It’s a good-news bad-news story,” said Trevor Houser, a partner at Rhodium and author of the report. “In the electricity sector we had a banner year — we had the largest decline in coal generation in recorded history. But in the other 75 percent of the economy, emissions remain stubbornly flat.”

Coal has been in a slow-motion death spiral over the past ten years. The country now generates half as much coal-fired electricity as it did in 2009. And that trend continued through last year, as coal generation slid 18 percent.

Surging natural gas was the biggest reason for coal’s demise. Gas comes with its own problems for the climate– burning it releases carbon, and leaks release methane — but replacing coal with gas led to a decline in globe-warming gases, Houser said. Renewable energy from hydroelectricity, solar power, and wind turbines, increased 6 percent in 2019. So despite President Donald Trump’s vows to resurrect coal, it’s still sliding into history.

The same can’t be said of gas-powered cars and gas-fired furnaces — for the moment, those look locked in.

Cleaning up the electrical grid is a great first step to cleaning up other sectors. With enough low-carbon electricity, more people could drive electric cars and ride electric trains. Builders could start installing electric heat pumps rather than gas furnaces in houses. “But that’s not going to happen on its own,” Hauser said.

Nudging people toward clean electricity requires policy: Efficiency standards, building codes, incentives, and taxes. Some state and local governments are making these changes, but at the federal level, the Trump administration is doing its best to stop them. As a result, the country’s energy use seems to have its own laws of motion. It takes a lot of work to change direction, but it’s relatively easy to let things keep running as normal. You can see that in coal’s continued slide, as well as in the status quo in emissions from factories, cars, and buildings.

An astonishing exploration of planet formation and the origins of life by one of the world’s most innovative planetary geologists. In 1959, the Soviet probe Luna 3 took the first photos of the far side of the moon. Even in their poor resolution, the images stunned scientists: the far side is an enormous mountainous expanse, not the vast lava-plains seen from Earth. Subsequent missions have confirmed this in much greater detail. How could this be, and what might it tell us about our own place in the universe? As it turns out, quite a lot. Fourteen billion years ago, the universe exploded into being, creating galaxies and stars. Planets formed out of the leftover dust and gas that coalesced into larger and larger bodies orbiting around each star. In a sort of heavenly survival of the fittest, planetary bodies smashed into each other until solar systems emerged. Curiously, instead of being relatively similar in terms of composition, the planets in our solar system, and the comets, asteroids, satellites and rings, are bewitchingly distinct. So, too, the halves of our moon. In When the Earth Had Two Moons, esteemed planetary geologist Erik Asphaug takes us on an exhilarating tour through the farthest reaches of time and our galaxy to find out why. Beautifully written and provocatively argued, When the Earth Had Two Moons is not only a mind-blowing astronomical tour but a profound inquiry into the nature of life here—and billions of miles from home.

Can Growth in Sustainable Energy Reduce Natural Resources Overspend?

Globally, we are consuming resources faster than the Earth can replenish them. If we think of these resources — such as timber, water, and clean air — like an allowance, then we spent our allotment for 2019 on July 29. We are over-fishing, extracting, mining, polluting, depleting, and harvesting resources across the globe.

We reach Earth Overshoot Day, the day when annual consumption exceeds the Earth’s capacity to renew itself, earlier and earlier each year. This means that we are consuming more resources than ever before — and at an increasing rate. For example, Earth Overshoot Day occurred in September in 2000, while in 1980 society overshot in November.

“It’s a pyramid scheme,” said Mathis Wackernagel, CEO and founder of Global Footprint Network. “It depends on using more and more from the future to pay for the present.”

Another daunting thought is that many people throughout the world consume far fewer resources than people in developed countries. Thus, one person in the United States will consume as many resources as 35 people in India. We would need 5 Earths to sustain us if the whole world lived like Americans. For comparison, we would need 3 Earths if we all lived like Germans, or 2.2 Earths if we all lived like Chinese. If the whole world lived like Indians, we would need 0.7 Earths to sustain us — in other words, we wouldn’t consume resources faster than our planet can replenish them.

Per capita carbon emissions in the United States are nearly double that of other wealthy nations, and roughly twice as many Americans are obese as our European counterparts. In other words, Americans could live a very comfortable life but consume far fewer resources.

What can be done to reverse this trend? It will take a political and cultural shift. Thankfully, there are many actions that we can all take to move in the right direction.

Calculate Your Ecological Footprint

A great way to get started is to calculate your personal ecological footprint. This can help pinpoint areas for improvement. Some of the easiest ways to reduce your impact are to use renewable energy, to reduce overall energy consumption, eat fewer animal products, buy less new stuff, live in a smaller home, drive less, and waste less food.

Celebrate Clean Energy Production Gains

Although the concept of Earth Overshoot Day is quite daunting, there is also good news about conserving resources. U.S. power generation from renewables  (that is, biomass, wind, geothermal, solar, and hydropower) surpassed coal in April 2019, according to the U.S. Energy Information Administration.

Wind and hydropower comprise the lion’s share of renewable energy production, but solar energy production is increasing. Renewables now comprise 23 percent of U.S. power generation compared to 20 percent from coal. This trend is helpful for reducing carbon emissions and resource consumption.

Power production from coal has decreased from its peak a decade ago, and another 4.1 gigawatts of capacity is expected to be retired this year. Meanwhile, much of the growth in renewable energy is attributed to growth in wind and solar energy capacity. In 2018, 15 gigawatts of capacity came online. To put this big number in context, 1 gigawatt of power is equal to the energy production from 3.125 million photovoltaic (PV) panels or 412 utility-scale wind turbines. It is enough energy to power 110 million LED lights.

This happened for a variety of reasons. The price of renewable energy is decreasing, people and companies have been demanding cleaner power.

Determine Your Electricity Mix

There are many simple items we can do to cut our personal ecological footprints, which can make a big difference collectively.

A great place to start is by examining where your power comes from and finding greener sources of energy. The power mix varies largely by subregions of the country. Some areas use more wind and hydropower, while some areas still use a lot of coal — and this has a big impact on our ecological footprint. The Environmental Protection Agency provides this information by subregions.

If your area uses more fossil fuels for power generation, then you will generate more emissions when consuming electricity. Look into how to offset your dirty-energy emissions.

Switch to Clean Power

Many utility companies offer optional programs to source more renewable energy. This is a great way to support clean energy without installing solar panels. CleanChoice Energy has a website to find out more about programs offered in your area.

Consider Going Solar

Installing solar panels on your roof is a great way to go green. In many states, homeowners can save money by going solar rather than purchasing power from the local utility company. As utility rates increase, going solar becomes more lucrative. Installing a solar system is also a great way to increase your property value.

Visit the EnergySage website for free solar quotes from local solar energy contractors.

Join a Community Solar Project

Unfortunately, many homes aren’t ideal for solar panels. Renters, condo dwellers, low-income households, and people with shaded roofs might not be good candidates for solar. In some cases, community solar farms or solar gardens are a great option.

Solar gardens are solar energy plants that are owned by a community of people or a third party. These projects allow a group of people to use the solar power that is generated nearby without having solar panels on their property. In many cases, the energy from community solar farms costs less than what people otherwise pay the local utility company. It often works like a subscription where you pay more to the solar farm but have a lower electric bill.

The prevalence of community solar farms varies a lot by state because some states have policies that make it difficult to develop such projects.

Launch a Clean Energy Campaign

If your utility company generates a lot of power from fossil fuels, consider launching a campaign to get your utility to use more clean power. Change.org is a great platform to utilize to gain momentum behind this project. You can also urge your state politicians to create stringent renewable portfolio standards. These state-wide regulations vary greatly by state and require utilities to increase their use of renewable power sources. If you live in an area with a weak standard, consider launching a campaign for stronger standards.

When will Earth Overshoot Day occur next year? Ultimately, it depends on our collective actions. Let’s get started to reduce our impact in 2020.

How to Compare Solar Energy Bids & Select a Solar Installer

More home and business owners are installing solar panels than ever before. And we now have a greater variety of panels and solar equipment to choose from than ever before. Depending on where you live, you probably have at least two or three solar installers that service your area. This means you have a lot of options when installing a solar energy system — which can be overwhelming.

Let’s explore some of the items to consider that will help you select a solar energy installer that can meet your needs.

Research Solar Installers

Like with any other home improvement project, it is wise to get at least two or three bids from licensed solar contractors with liability insurance. Here are a few ideas for finding potential installers.

Seek Recommendations & Online Reviews

If you know people with solar systems, you can ask them about their experience and possibly get referrals that way. Online reviews are also a good way to find some of the best installers in your area. Consider how long the company has been in business, the depth of their experience, their credentials, and their reputation.

Consider Local Businesses

Whenever possible, support small, locally-owned businesses. This is beneficial for your local economy and maybe even your pocketbook. A study from the National Renewable Energy Labs (NREL) found that small- to mid-sized installers charge 10 percent less than big installers.

Review Solar Contractor Qualifications

Another important thing to consider is the qualifications of a given solar contractor. The North American Board of Certified Energy Practitioners (NABCEP) certifies solar PV installers. Their requirements involve passing a written test and accumulating a certain amount of solar field experience. NABCEP certification doesn’t guarantee quality workmanship, but it does ensure a certain level of solar energy expertise and installation experience. Ideally, a NABCEP-certified professional will oversee your solar installation — or you will even have a NABCEP-certified installer on the roof.

Check Installer’s Use of Subcontractors

It is also helpful to know if a solar installer subcontracts out some or all of the solar installation. If so, find out what work the contractor will do themselves and what they outsource to a subcontractor. Subcontracting part of the job isn’t necessarily bad news. For example, they might subcontract a roofer to flash around the installation, which could improve the quality of the final results. 

Compare Project Quotes

Now that you have received quotes from at least two or three reputable solar installers, it is time to compare them. This could be a bit more difficult than you might expect because it is rarely an apples-to-apples comparison.

Some of the most crucial things to consider are the warranties, quality of the solar equipment, appearance of the solar panels, financing, and when they can complete your installation.

Warranties

The solar equipment will come with its own set of warranties — this varies by the manufacturer and equipment model. There should also be a warranty on labor. Keep in mind that equipment failure can often require a couple of people to climb up on your roof to repair it. This can get expensive if labor is not covered. The more reputable equipment manufacturers and solar contractors are more likely to honor their warranties and to be in business down the road.

Equipment

Solar installers tend to have solar panels, inverters, and racking equipment that they prefer using. If you are particularly excited about a particular solar product, you can ask the contractor if they will use this equipment. This can also make it easier to make a more accurate comparison between installers’ quotes.

If you don’t have particular products in mind, it is still important to consider the quality of the equipment and that it fits your priorities. Some of the most relevant considerations for solar panels are their long-term power generation, product warranties, environmental performance, appearance, and module testing performance. Cheaper solar panels have a lower upfront cost, but they may also produce less power down the line. Some panels might be more expensive partially because they have a sleek, all-black appearance, which may not be a top priority to you.

Financing

Many solar installers partner with financing companies. If you need a loan to install your solar system, consider the financing company they use. For example, what are their rates, fees, and monthly payments? This not an issue if you do not need financing or you are not going through the solar installer to obtain a loan.

Scheduling

When comparing bids, it is also helpful to know when a given installer can get started. Because solar is booming, some contractors have a very full schedule for months. When your solar system is installed can also impact the percentage of the federal solar tax credit as it will taper down for the next several years, effective on the first of each year.

Power Generation

Another thing to consider is power generation. Many contracts will offer estimates on how much electricity a given solar system will produce. Some installers use more conservative methods when estimating this than others, so you do not want to take their estimates literally. For example, one installer may estimate that your roof is more shaded than another installer’s estimate. This means you may want to verify these numbers to make a more accurate comparison between bids. To do this, visit PVWatts Calculator by NREL.

It is a good idea to consider your future electric needs. If a given solar system is estimated to produce more than 100 percent of your electricity needs, it may be larger than necessary. Do you plan a purchase in the near future that will increase your power consumption, such as an electric vehicle or a heat pump? If so, it is useful to slightly oversize the solar system for the time being.

Electric Bill Savings

Also, installers may estimate your electric bill savings. Make sure they used an accurate power rate by viewing your electric bills.

Examine the Contract

It is common when reading solar installer reviews to find dissatisfied customers. In many cases, the salesperson promised the customer something verbally that they didn’t deliver on.

Make sure everything that the salesperson promised is included in the terms in the contract. For example, if your solar installer promised the solar company would remove and reinstall the solar system when the roof is replaced, make sure it is in the contract. If the salesperson promised the system would be installed by December 31, before the federal tax credit tapers down a few percentage points, look for that in the contract.

Young people are spending more and more time on devices. Kids between the ages of eight and 12 spend nearly six hours online daily on average. Although this statistic seems quite high, it is important to consider what children are doing online.

There are many educational websites and online games that teach children about nature, the climate crisis, or how to recycle. Unfortunately, some of these are not all that engaging, judging from my kid’s responses to them. Others teach about the natural world but don’t specifically teach young people about living greener lives.

Let’s explore some of the best green websites for young people.

Super Sorter

Super Sorter is an engaging game that takes children to a materials recovery facility to sort mixed recyclables. Plastic bottles, glass containers, and cardboard boxes appear on a conveyor belt where they must be sorted by one of four different technologies. Each sorter specializes in capturing different types of materials so players purchase and place the sorters strategically to have the highest recovery rate.

After watching kids play this game, it does seem to genuinely teach the concept that specific infrastructure is needed to have high recovery rates for single-stream recycling. It is ideal for late elementary age students and older.

PBS Nature Games

The PBS Kids website has a collection of nature games for elementary school-aged kids with a variety of themes. Gamers learn about ecosystems, bird species, constellations, soil health, geography, and more while playing. The object of the games is sometimes being a steward of nature or the environment, like managing renewable energy production, feeding winter birds, and creating wildlife habitat.

Much of the information is offered as a narrative during the game, which some kids might tune out. If nothing else, kids will gain exposure to certain vocabulary that could be helpful later on. These games are ideal for elementary-age children and often don’t require the ability to read.

National Geographic Kids

The National Geographic Kids website has a variety of resources that teach children about different animal species, planets, and special places. Kids can take a pledge to cut back on the use of disposable plastic, learn about amazing animals, or test their knowledge on a given topic with a quiz.

Rich graphics help keep this site interesting to kids, but aside from the videos, many activities require an ability to read. This website is ideal for late-elementary-age students and older. Most early-elementary-age children will need some help from an adult but will likely find the content interesting.

Ranger Rick

Ranger Rick is an interactive website that teaches children about different animals, provides instruction on craft projects, and has some jokes and games. Like National Geographic Kids, the website has excellent graphics and is well organized for young users.

Although Ranger Rick teaches children about the natural world, the website doesn’t necessarily teach children much about more sustainable lifestyle choices and conservation. One year of full access is $10. Because many activities require an ability to read, most early-elementary-age kids will need some assistance from an adult.
