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.

Look Where We Need Family Planning the Most

Thursday, April 27th, 2017

“As we crawled through the city, we encountered a crowded slum area. The temperature was well over 100, and the air was a haze of dust and smoke. The streets seemed alive with people. People eating, people washing, people sleeping. People visiting, arguing, and screaming. People thrusting their hands through the taxi window, begging. People defecating and urinating. People clinging to buses. People herding animals. People, people, people, people.”   Ann and Paul Ehrlich in Population Bomb, 1968

Impact = Population x Affluence (consumption) x Technology

                                                Ehrlich and Holdren, 1971

 

Close your eyes for a moment and conjure up an image of overpopulation. Did you picture hundreds of people hanging off a train in India? or dark-skinned crowds in a street in a poor country?

Yes, family planning is important in those scenarios. Voluntary access to modern contraception is important for humanitarian reasons in the global south. You probably know the litany of its benefits: decreased maternal mortality, healthier children, economic savings, progress in standard of living and education, local environmental protection.

However, the need for effective, universal access to family planning and to safe, legal abortion is much more important in rich countries in the global north. This is because of the issue of consumption.

What! you might be asking. The average woman in many African countries has 5 or more children. Niger tops the list; the total fertility rate there is over 7! Surely the population explosion there must be causing problems. Yes, Niger is one of the lowest ranked countries in the UN’s Human Development Index. Repeated drought has caused famine; population pressure and overgrazing cause environmental degradation.

Let’s compare two countries in the Western Hemisphere—the USA and Haiti. They are, respectively, one of the richest and one of the poorest in the world. The carbon footprint of an average person in the USA is about 20 tons of CO2 per year, while that of a Haitian is 0.2 tons—one hundredth of ours! Thus it would take a hundred Haitians to equal the climate damage done by one of us.

Another way to compare the impact of a single person in the two countries is with Ecological Footprint. The ratio between the two countries is 16 to 1. Thus 16 kids of a really large Haitian family would have the same impact of a single-child family in the USA. I have to admit that there are several problems with this comparison: it doesn’t include the two parents, the average Haitian family size is just a little over 3 so I doubt that there are many as large as 16. The legacy of a large family grows over generations. In Niger, if each generation has 7 children, the number of grandchildren would be 49!

The two measures of impact are different. The carbon footprint is global, since carbon emissions into the atmosphere spread over the whole planet. The Ecological Footprint includes carbon emissions, but it also includes effects that are localized, such as damage to the local environment. In any case, the impact of a person in the USA is much greater than one in Haiti or Niger, and it is spread over the planet.

There is good news! The unintended pregnancy rate (this includes mistimed and unwanted pregnancies) has dropped significantly in the USA. Whereas this rate has hovered at about 50% for years, the latest information is that it has dropped to 45%. The news is especially good for young women, when an unintended pregnancy can be devastating. This decrease is due to increasing use of effective contraception. It is very concerning that the new administration threatens women’s reproductive health and may make contraception and abortion services either unaffordable or totally unavailable.© Richard Grossman MD, 2017
