Use More Renewable Electricity

While our government in Washington is struggling to deny climate change, we can take action locally. Our electric coop, La Plata Electric Association (LPEA), offers easy ways to do this by purchasing renewable power.

Isn’t all electricity the same? Yes, it is, if it comes through wires attached to the electrical grid. Let’s look at reasons you might want to use electricity generated in a renewable way. Do you have asthma like I do? Millions of other people in our country suffer from this and other respiratory afflictions. Breathing is made more difficult by the fine particles that escape from coal fired power plants and by smog that comes from the ozone generated by natural gas development. Those tiny particles are invisible but cause atmospheric haze. Worse is that they are also responsible for loss of life due to cancer and heart attacks.

We are already suffering the effects of climate change. Despite the welcome snow this month, southwest Colorado is still at the worst level of drought. The huge 416 wild fire last summer was much too close to home. Climate change has prolonged the forest fire season and has helped to create many more mega-fires. We are seeing the effects of anthropocentric climate disruption already! One action that we can take to slow climate change is to use less electricity generated by burning fossil fuels.

In addition to fouling the air, power plants are some of the biggest users of fresh water, which they use for cooling. Although some of the water is returned to streams or rivers, it is hotter, which can be fatal for fish and other animals. Some think that nuclear is the safest source since it is less polluting.

Every source of electricity has its drawbacks, unfortunately. This is why I sometimes write about energy in columns that focus on human population. Almost everything that people do has detrimental effects to the natural world. We can decrease that impact by decreasing the number of people, by consuming less and by technology. Using renewable power is one way of minimizing our impact.

LPEA has 2 voluntary programs to promote renewable or “green” power generated by solar, wind or hydro. Our electrical cooperative can provide part or all of your electricity from these renewable sources. The extra cost is minimal, only about 50¢ a month for the average LPEA member. A call to their friendly office staff can give you more information. They also have a program to fund local solar arrays. This Renewable Generation Fund is currently helping to support 4 projects at nonprofits. 

Your first step should be to look for ways to use less energy. That saves money and diminishes one’s impact. Turn off lights you don’t need, and install dimmers if you don’t always need to run lights at full brightness. Our local 4CORE specializes in home energy efficiency. It offers ideas to decrease waste of electricity and rebates for Energy Star® appliances.

LPEA has a great program to reimburse you for half of the cost of certain efficient LED bulbs. These use only a fraction of the “juice” of traditional incandescent bulbs and are more efficient, and safer than compact fluorescents. I’ve taken advantage of this program in the past, buying a few LEDs at a time, but I went hog-wild this year since it is the last year of the program. Soon almost all the light in our home will come from the sun or LED bulbs! LEDs are much improved and the price has come down dramatically. To find out more about this rebate program go to www.LPEA.coop—but be careful to follow the instructions carefully.

We are tied to Tri-State Generation and Transmission for all of our electricity except what is generated locally. Despite the decreasing costs of solar panels, soon people won’t be able to install solar arrays because the contract with Tri-State, which limits the amount of power that can be generated locally. Because so much of their energy comes from burning coal, they are rumored to be the most polluting power supplier in the country. Tri-State has been slow to convert to renewable sources but it appears that they are finally seeing the light; they are installing a huge solar array north of Trinidad, Colorado.

We can be proud of our electric coop for its support of renewable power, especially with its new policy to cut its carbon footprint by 50% by 2030, while keeping rates low. We need to keep pressure on Tri-State to increase their low limit on locally generated renewable power.

Inspire the United Nations

Sunday, December 23rd, 2018

The Intergovernmental Panel on Climate Change (IPCC) has done wonders by motivating individuals and nations to take action to slow climate change. What could happen if the United Nations formed a similar organization to slow population growth?

I probably don’t need to remind you that far and away the most effective way of slowing climate change is with small families. Indeed, of all the actions that an individual can take, having one fewer child is 14 times more effective than avoiding air travel, being a vegetarian, changing light bulbs and recycling—combined! Fortunately people all over the world are choosing to have fewer children, although I imagine that few are doing this for environmental reasons.

A friend, Rob Harding, has been working tirelessly to form a Framework Convention on Population Growth. The UN states a framework convention: “…describes a type of legally binding treaty which establishes broader commitments for its parties and leaves the setting of specific targets either to subsequent more detailed agreements… or to national legislation.” The IPCC was established by the Framework Convention on Climate Change.

Harding recently attended COP24 (the annual international UN meeting to work on climate change) in Poland in order to witness how the IPCC works and to make contact with UN officials. He has written a description of his proposal for Scientists Warning, available at: https://tinyurl.com/UN-Pop-Proposal.

Harding proposes that the UN take 3 routes to slow population growth. The first is education, which is already well known to have many benefits, including a decrease in family size. Indeed, educating girls and women is one of the most effective means to do this, for several reasons. Educated women are more likely to get married later, to be more independent of their husbands and to use contraception effectively. A further benefit of education is that the offspring of educated parents are more likely to live through childhood. The mother and father will know more about sanitation, will have better incomes and will seek medical care when their kids need it. There is another advantage that might seem paradoxical: parents choose smaller families if they know that their kids will survive to adulthood.

The second effort is to make it easy for people to have access to effective contraception. Harding is careful to specify that there mustn’t be coercion. the 1994 UN’s International Conference on Population and Development turned away from family planning because of the bad experience with coercion in places such as India and China. I feel that it is very important that all family planning programs be voluntary.

I am pleased that Rob decries coercion. The most valid concern that anyone has expressed over his proposal is that the panel might be set up similar to the structure of the IPCC, where each country has a goal to reduce emissions. Goals for the number of people who used contraception (especially sterilization) are blamed for the coercive policies in India and China.

Finally, Harding’s proposal recommends promotion of smaller family size. One of the most remarkable examples of a way to influence family size influence is accidental. In Brazil apparently everyone watches TV, and soap operas are particularly popular. The families in the “soaps” are all small. This is not because the producers want to influence family size choices, but because it is difficult to manage children on a TV set. The average woman had 6 or more children 60 years ago but now the average is less than 2! One of my favorite nonprofit organizations, the Population Media Center, has worked to influence family size choices in many countries using radio and TV shows. Their methodology is very effective, including in Africa where men often want larger families than their wives, according to studies.

Although Harding is employed by a nonprofit organization that is concerned about population, he has been doing this proposal to the UN on his own time. He has already garnered support from several thousand people and about 50 organizations! His hope is to expand the network of people who are interested in the proposal, and perhaps even to find an organization that would take it over as one of its programs.

My impression, when talking with Harding after he returned home from Poland, was that the climate talks were not very productive. I also sensed that he got a dose of the complexity of the United Nations—but he is not discouraged from persisting with his important task of inspiring the UN to recognize and tackle the population problem.

Solve Climate Weirding

Tuesday, August 28th, 2018

The summer isn’t over and already the fires have been terrible. What is causing all this trouble?

We had the huge 416 fire just north of Durango. Over 54,000 acres of our precious land has burnt in this fire alone, and there are many other wildfires near by. The 416 was terrible because it was so close to Durango, and because it was apparently started by an ember from our beloved Durango and Silverton Railroad.

Much of the American Southwest is experiencing exceptionally dry conditions. I recently discovered that there are four levels of drought, according to National Integrated Drought Information System (www.drought.gov). Much of the Southwest is at the worst level—Exceptional Drought. Unfortunately, we are not alone.

My wife and I recently traveled in Scotland and Norway. It was dry everywhere, with brown replacing the usual green. We didn’t need warm clothes the we packed since we were well inside the Arctic Circle. We wandered around the North Cape of Norway—the farthest north of that northern country—with only light jackets. 

Greece has suffered from disastrous fires, with the loss of many lives. Even northern Sweden is suffering from wildfires, which is very unusual. What is causing this hellish inferno? 

Of course, part of the answer is global climate change, which I like to call “global weirding” because different places get hit in different ways. While we are suffering from drought, the Northeast has been inundated with floods.

Almost all scientists agree that the climate is “weird” because of our use of fossil fuels. A recent article from Science supports this. The temperature changes in the north latitudes have been found to match the “fingerprint” of what computers predict, giving still more credence that climate change is anthropogenic. The article’s conclusion is: “Our results… provide powerful and novel evidence for a statistically significant human effect on Earth’s climate.” 

Not all people are affected by climate change equally. The far north is heating up faster than the tropics. Poor people also get the brunt of this weirding—they are more likely to work outside or to live in high density cities with the “heat island” effect. On the other hand, the fortunate among us can resort to air conditioning.  However, AC is counterproductive in the long run since most electricity is generated with fossil fuels.

What can be done to slow climate change? In the short run reducing carbon emissions will help. We donate to offset our carbon emissions to organizations such as American Forests. Having small families is the best way to reduce carbon emissions for the long run. That is because each additional person added to the population increases carbon emissions—the fewer people, the less greenhouse gases. If you look at all the future generations that are likely to follow a child born today, the effect of having one fewer child is huge.

Last year Fort Lewis College hosted a symposium on the science of climate change. We were hoping to have 200 people attend and were pleased that there were almost double that number! Most impressive was the teacher of a high school environmental studies class in Cortez who brought her students. Encouraged by such a good response to last year’s meeting, I am helping to organize a second event—“Climate Change Solutions”. It will be held at Fort Lewis College on October 30th. Please save the date!

There will be an amazing lineup of speakers, two of whom will decrease their carbon footprints by appearing digitally. Senator Michael Bennet’s staff—or perhaps the senator himself—will be there in person. The senator is not campaigning for office this year but will update us on what is happening in Washington and Colorado to slow climate change. We will have a return visit from philosopher Travis Rieder who gave a wonderful Lifelong Learning talk last year on the ethical imperative of small families. Dr. Katharine Hayhoe is a climate scientist and member of the Nobel Prize winning International Panel on Climate Change. She and Dr. Karin Kirk, a member of the Yale Climate Connections, will be focusing on communicating about climate change.

Climate Change Solutions will have two sessions that Tuesday—one in the afternoon and one in the evening. Both will be open to anyone, but the afternoon is especially for students; we are arranging for 380 students from local high schools to attend. After all, it is they who will suffer the most from climate change. We won’t solve climate weirding at this symposium, but people can learn ways to slow it down.
