A 2-Step Plan to Kick Fossil Fuels

A Life-Changing Talk Leads to an Energy Plan

Like many people, I want to do what I can to live more sustainably and to reduce my carbon footprint and dependence on fossil fuels. But once you get past the obvious stuff (changing light bulbs, adding insulation), the next step – and the one after that – is not always clear.

That’s what I wanted to know when I attended a seminar at the U of M called “Energy from Renewables: Confronting Global Collapse” in October 2016.

That event changed my life. Here’s why.

Efficiency Won’t Cut It. We Have to Power Down.

The Sacred Cow of Energy Efficiency is Really a Trojan Horse

Andrew Nikiforuk, a Canadian journalist writing on energy topics, published an insightful article last month on “The Curse of Energy Efficiency.” I’m going to give you a synopsis and then talk about how we can overcome the problem he identified.

If you follow Xcel, the Department of Commerce, the state legislaturereally, anyone working on energyyou know that efficiency is the key to deep reductions in energy use. According to Nikiforuk, the International Energy Agency said energy efficiency could achieve 49% of the greenhouse gas reductions we need by 2030.

And it’s certainly true that we’ve made huge strides in energy efficiency in almost every type of electrified product. Computers are more efficient. Cars and planes are more efficient. Kitchen appliances are 75% more efficient than they were in the 1990s! We should be saving lots of energy, and be well on our way to lowering our carbon footprint.

But we’re not.

The truth is, increases in energy efficiency encourage more use. Stanley Jevons, a coal economist, noted years ago that efficiencies in technology encouraged industry to apply that technology to more and more activities. Jevon’s observation is called the Jevon’s Paradox.

Energy Workshop is a Call to Action

I attended a day-long seminar at the engineering school at the U of M back in October: “Energy from Renewables: Confronting Global Collapse.” It was a mix of hope and despair. Lots of good information, much of it new to me. And a clear message that our timeline for action is really, really short. Various speakers offered guidance on steps we need to take right now, and glimpses of amazing technologies that we can only hope will be perfected and rolled out in the near future.

After attending that seminar, any talk about 2050 is no longer credible to me. We do not have that long to make a significant change. According to folks at The Solutions Project, we need to shift to 80% renewables by 2030. So tell me what we can do today and by 2020 and by 2025.

Energy Seminar Lights a Fire

Action 1: Work immediately on energy efficiency in every possible way. Dig into your energy bills. Cut!

Action 2: Reduce your carbon footprint immediately. If you drive more than 8,000 miles a year, lease an electric car. Some things may need to fly, but you and I are not among them.

Action 3: Electrify your life. Shift everything you can to electric and shift your electricity to solar or other renewables. If you can afford rooftop solar, do it now (and with batteries). If you can’t but want it, see if you can do a bulk buy deal with some neighbors to get the price down. If you can’t do that, buy into a community solar garden even if it doesn’t save you money.

Stop thinking that money is your return on investment. A livable climate is the only return that counts right now. Invest in life.

Action 4: Think twice about rice. That food is responsible for 46% of all crop-related greenhouse gas emissions. Eat local, reduce meat consumption, support responsible farmers. Know that when raised right, grazing animals are good for the land. (Think about it, they evolved together and this country used to be home to millions of buffalo.)

Action 5: If you own land, reforest and food forest. Gardeners, do not buy peat.

Action 6: Practice hospitality now, in a variety of ways, so you will be prepared to practice it in earnest in the not too distant future. Greenland has lost a trillion tons of ice in four years and ice melt is accelerating, as is sea level rise. Your Florida relatives may soon be living with you.

Our business schools are a training ground for climate denial, which prevents action from occurring and regulations from being adopted. Our business schools need to be confronted and transformed.

The media has been a tool in the hands of deniers. They need to be held accountable. In 1996, the Minnesota News Council DID hold one of them accountable for turning to a famous climate denier for “balance” in a news story. The News Council no longer exists, but you and I are still here. We must raise a ruckus to shine a light on false stories, false premises, false “fairness.”

Thinking About Consumption: “Highest Use”

One of the things I’ve been thinking about is whether I am using something for its “highest use ” or “highest purpose” – something like electricity or space or whatever. If what I’m doing is not its highest use (general lighting rather than task lighting, for example) could I avoid using it if there is a negative cost to it (walk through a dimly lit room)? Is there something else I could do?

I recently became aware of the fact that desktop computers use a lot more power than laptops (supposedly), which use more power than tablets and phones. When I turn on my very old desktop computer for some small task, or just to stay connected to Facebook, how much electricity am I actually using? I decided to look it up.

Permaculture Principle 2: Catch and Store Energy

I love this principle because it fits with my belief that we should look at every building and bit of land as having the potential to fulfill multiple functions and that each function should be maximized together as a system, not maximizing one discrete function at the expense of others.

For example, this house and yard are not just a place to house people and store things, but can also be a space to:

  • Create energy (or reduce energy use through good design)
  • Collect and store rainwater for later use
  • Move rainwater down to the soil and not into the storm sewer
  • Grow food for people, for pollinators, for critters
  • Promote learning
  • Heal people
  • Connect people and create community
  • Create beauty and appreciation for nature

Some would say that a green lawn is beautiful and that is its function. My personal belief is that beauty is not sufficient unto itself but that it should be part of each and every function mentioned above. Beauty and function should both inform the ends to which we hope to arrive.

So how does this principle of storing energy inform our decision making? We start by identifying where energy exists in our landscape and then look at ways we can capture it.

This is a simple, portable solar cooker.

This is a simple, portable solar cooker.

The Sun: Our solar panels collect sunlight and convert it to electricity, but there are a lot of less expensive or zero-expense ways to use the sun’s energy. We use solar lights in the garden and on our front porch to bring a bit of enchantment and illumination to the evening. For example, solar heating:

  • While we use solar hot air panels on the side of our house to collect heat from the winter sun, any house with a south-facing window can benefit from passive solar heat gain.
  • You can use the sun to make sun tea in a large glass jar or to cook food with a homemade solar oven.
  • You can dry herbs, berries, fruits and veggies with a solar dehydrator (or the back window of a car).
  • You can heat water either with panels for solar water heating or for camp showers. (Check out this kickstarter for a cool on-the-go hot water heater.)
  • You can build a greenhouse or cloche to capture solar heat and extend your growing season.

Wind power: A small wind turbine can generate electricity for home or garden use (if it’s not illegal in your area). A row of tall trees can “catch” wind and store it to prevent it from reaching your home or yard.

Biomass: Compost provides a lot of heat at certain times of the year. Our grape vines are planted near the compost, which keeps their roots warmer. I don’t know if that’s good for them but the ones by the compost are twice as tall as the one’s next to them that aren’t by the compost. Of course, little critters also know it’s a warm space and it’s not unusual for a mouse to jump out when we turn it over in the spring.

Biomass-intensive landscaping can also be used to store water in drought-prone areas. Swales and berms can direct the flow of water.

Food is energy, too. We can preserve food using the natural enzymatic process of fermentation. One permaculture website I read talked about the energy of milk being captured and stored by cheese. I’d never thought of it that way, but I quite like that idea.

Personal Permaculture: The Big Picture

Permaculture principles can also be applied in our lives and the folks in the Transition Longfellow Saturday group had lots of ideas for how to capture personal energy when we have it so we don’t need to expend it when we’re tired.

  • Prepare food in advance and put it in the freezer for quick reheating.
  • Get work ready the night before. Set out your clothes in advance.
  • From the women with chronic fatigue and fibromyalgia, don’t put things off until tomorrow if you have the energy to do it today.
  • Work with your personal energy pattern (whenever possible). Plan to get things done during the time of day when you feel most alert and then rest.

Money is another form of energy. It can bring growth or stagnation, depending on how it is used or hoarded. For example:

  • Money spent at a local business rather than a chain store stays in the local community and is reused many more times, creating a lot more economic activity. Money spent at a chain store typically leaves the community.
  • Money deposited in a community bank is used to lend money in the community, building even more economic activity. Money deposited at national – too big to fail – banks may actually become a drain in the community, especially if that bank is responsible for a large number of foreclosures in your area.

Calculating the Impact of the Motor Scooter

Leslie and Rachel head out on the scooter

This weekend we replaced the battery on the Kymco People 50 motor scooter that Peter rides to work. With a new $50 battery in place, he zoomed off this morning in high spirits, reporting back that the odometer hit 15,000 miles! Seems a good time to take a look at the overall impact of this purchase.

Peter gets 90 miles per gallon of gas when he rides the scooter to work (10.5 miles round trip). He gets 27 mpg when driving the car. We’ve saved half the cost of the scooter in gas savings.

The burning of one gallon of gas (with 10% ethanol) produces 18.95 lbs of carbon. Driving the scooter 15,000 miles has produced 3,148 lbs of carbon (or 1.58 short tons). Driving the car the same number of miles produced 10,152 lbs of carbon (5.08 short tons). So driving the scooter prevented 6,998 lbs of carbon (3.5 tons) from entering the atmosphere.

And the scooter is fun!

Kitchen Remodel & Energy Efficiency: Natural Gas

Taking The Leap FROM Natural Gas

Like most Minnesotans, we use natural gas to heat our home and our water, and we used it to cook our food. It’s an accepted fact that “natural gas is cheaper and easier to cook with.” But this remodel was all about looking into the future and rethinking common knowledge.

We had to ask ourselves, is it time we disconnect from natural gas?

Kitchen Remodel & Energy Efficiency: Electricity

I admit it — I’m a design junkie. I watch all the kitchen design shows, follow Houzz, Kitchn and TinyHouse, and regularly attend the Minneapolis/St. Paul Home Tour. I have a Pinterest page where I collect images of kitchen efficiency and kitchen remodeling.

Function and aesthetics are the two most common reasons that propel people into the formidable undertaking of a kitchen remodel. But energy is at the center of a kitchen’s function, not counter tops or traffic flow. Few and far between are the videos and articles in the design arena that look at energy efficiency and nothing I found gave any consideration to our energy future.

How Thinking of Sustainability Affected our Kitchen Remodel Project

We really USE our house. We host neighborhood soup nights, community meetings, discussion groups, game nights … all with a side of food and drink. We can tomatoes and pickles, sprout seeds, brew beer and wine, bake bread and culture the occasional yogurt. We do it all in a typical South Minneapolis bungalow kitchen that measures 9′ x 10′.

Not a lot of space to move in the old kitchen

Not a lot of space to move in the old kitchen

One evening, while watching 4 people bump into each other getting ready for a potluck, I thought to myself, “This is just not working! I’ve GOT to do something with this kitchen, NOW!”

What had stopped me in the past was, of course, the money. Kitchens are the most expensive room to remodel and ours would be no exception, since little had been done to it since the house was built in 1921. But this time, exasperation pushed me all the way to the doors of the community bank. We weren’t getting any younger – or richer. If we didn’t do something now, it was increasingly unlikely we’d do it later. Loan in hand, we were ready to begin.

Good News: PUC Sets New Values for Health & Environmental Cost of Energy

Train derailments, pipeline spills, explosions – it feels like the energy sector is just one bad news story after another, but that’s not the case in Minnesota. We’ve got a little celebrating to do!

At the end of December, the Minnesota Public Utilities Commission (PUC) voted 4 to 1 to update (or set) environmental cost values for sulfur dioxide, nitrous oxide, fine particulate matter and carbon dioxide when it comes to electricity planning.

They did so in response to a petition from Fresh Energy, the Minnesota Pollution Control Agency, the Minnesota Department of Commerce, the American Lung Association in Minnesota, the City of Minneapolis, and a lot of concerned citizens.

This change in how the PUC looks at proposals from energy companies could have a big impact on the most polluting power plants in our state. That, in turn, can have a big impact on the health of Minnesotans who live near those plants and all of us who breathe in polluted air. These pollutants are strongly linked to increases in heart attacks, strokes, asthma and lung diseases.

This change was made possible by legislators back in 1992 who, with bipartisan agreement, required the PUC to consider the health and environmental costs of producing electricity when it made its decisions. A dollar value for some of the damaging pollutants was set in 1997 but those values were low and were never updated.

In September 2013, economist Stephen Polasky, from the University of Minnesota, estimated that the real annual damages to human health and the environment caused by the generation of electricity were at least $2.1 billion. The numbers the PUC was using in energy resource planning were far too low.

While petitioners asked that the PUC use the numbers provided by Dr. Polasky, it will ultimately be an administrative law judge who will provide the PUC with a recommendation on the appropriate new range of cost values for electricity planning.

According to Fresh Energy, when the full cost of damage to human health and the environment are considered in planning for future energy investment, clean energy options will finally be on a level playing field.
