Just Because It’s Free Doesn’t Mean You Should Waste It

I’ve become the power police.

My Neighbor's TrailerThis photo shows the trailer parked in the spot next to mine. It’s been here longer than me and I suspect it isn’t going anywhere soon.

For a while, a family of four and dog lived in it. They kept weird hours. They’d come home between 9 PM and 11 PM, make a bunch of noise, and then go inside and (I assume) sleep. Occasionally, before turning in, one of them would do something in the car with the key in the ignition and the door open so it would beep-beep-beep for 20 minutes at a time. In the morning, around 10 AM to 11 AM, the door would open and they’d begin spilling out in their pajamas. After screwing around at the trailer for a while, they’d leave. The whole process would start again that night.

About a month ago, they started leaving the “porch” light on. This makes sense when you know you’re going to get in late, but what bugged me is that they never turned it off. And while this isn’t a huge deal if they’re parked all by themselves, their porch light is about 10 feet from one of my bedroom windows. It’s so bright outside at night that I actually woke up in the middle of the night last week and thought it was morning.

It was morning. One o’clock in the morning.

I considered asking them to turn if off at night when they got in, but I was too embarrassed. They were a family of four in a 20-year-old 22-foot travel trailer with a dog. I was a family of one in a brand new 36-foot fifth wheel trailer with a parrot. I had no right to whine.

About two weeks ago, they started leaving the air conditioning on all day long, even when they — and their little dog — were out. They also left the two top vents and one of the windows open. Air conditioning on, windows closed isn’t bad. Air conditioning off, windows open is good. But air conditioning on, windows open is wasteful — especially when no one is home.

The campground we’re in is dirt cheap: $200 per month for a full hookup! There’s no electric meter, so you can suck as much power as you want. But that doesn’t mean you should suck power when you don’t need to. Or blatantly waste it.

About a week ago, they stopped coming home. I don’t know where the hell they are. For all I know, they’ve been deported.

So now there’s a vacant trailer next door with its porch light on, shining into my bedroom window, and the air conditioning blowing cold air out the open vents and windows. 24/7.

It gets cool here at night — in the 60s most nights. The kind of night you want to leave your windows open to feel the fresh breeze and hear the wind in the trees.

Of course, with windows and blinds open, I get to hear the air conditioning from next door and have that damn light shining on me.

I mentioned the light to some folks I had dinner with last night. They all told me to pull the bulb out.

But last night, I did something better. I snuck around to their electrical box and turned off their circuit breaker. Instant silence, instant dark.

I slept very well last night.

They didn’t come home. Although I was tempted to leave everything turned off, I know they have an electric refrigerator — the kind you buy for a dorm room; I saw them bring it in the day I moved in — and I was worried that the food inside it (if there was any) would spoil. So before taking my walk this morning, I flicked everything back on.

Tonight, I’ll flick it off again.

I figure that if they show up, they’ll just assume the circuit breaker popped. Maybe they’ll even get the idea that they shouldn’t leave the air conditioning on when they’re not around.

My Electric Blanket

A “blankie” for a grown woman?

Back in the winter of 1977, when I was 15 years old, my family relocated from northern New Jersey to Long Island, NY. We went from an old house built in 1901 to a much more modern home built in the late 1960s. But best of all, for the first time in my life, I had my own room.

Our arrival in Long Island was about a year before the energy crisis that would strike the country. To save energy (and money) — the house was heated with an oil furnace — my stepdad fitted the house with set-back thermostats that would automatically drop the heat to 62°F at night. To make sure we were all warm and comfy at night, my sister, brother, and I were issued electric blankets.

Clash of the Technologies

Clash of the technologies: the control for my 32-year-old electric blanket seems slightly out of place in this digital world.

If you’re not familiar with electric blankets, here’s how they work — or at least my understanding of them. They’re made with two layers of a synthetic fabric with a series of wires running up and down between the two layers. I assume the wires have some kind of heat emitting properties. At the bottom end is a socket for a plug. A control device plugs into the socket with a long wire — the idea is to put the control on your bedside table, so the wire is at least as long as a bed. Another wire plugs into a wall outlet. When you get into bed, you turn the blanket on and use the control to dial in a setting.

It must have worked, because I don’t recall being uncomfortable on cold winter nights — except, of course, those nights after an ice storm knocked out power for 11 days.

A few years later, when I moved onto my college campus, I brought the blanket with me. And I brought it with me when I got my first apartment. And when I moved into a new apartment with my future husband. And when we moved into our first house. And when we moved into our second house. And when I began spending summers in an RV in Central Washington State.

The blanket, which is now 32 years old, is with me on this trip. And I’m glad to have it.

When I first arrive in Quincy Washington at the end of May, it’s downright cold at night. RVs have three problems when it comes to heat:

  • They are generally poorly insulated so they can’t hold heat well. This RV is much better than my previous one, which had two tent walls.
  • Their heaters are unbelievably loud, consisting of a gas furnace and a loud blower that attempts to shoot hot air throughout the space.
  • Their heaters don’t evenly heat the space. Face it: what heater does?

The first season I was here in my old RV, I slept under a pile of blankets. No exaggeration — my first few weeks were spent on flannel sheets under every single blanket I’d brought with me. It was like sleeping between two mattresses. I still had to wear flannel pajama pants to keep warm.

I got a case of the smarts the next year and brought the old electric blanket with me. That made all the difference in the world.

Now all the instructions that come with these blankets tell you to make the blanket the top layer. But I usually sandwich the blanket between my top sheet and a lightweight comforter. As a result, I can set the blanket to “1″ or “2″ (on dial that goes to 10) and keep very warm.

The blanket is for a twin size bed and my bed in the RV is a queen. But the blanket covers the top pretty well. It makes for very cozy sleeping.

My big problem now is getting out of that nice warm bed in the morning.

Solar Power Woes

Why we won’t be buying a solar energy setup for our new RV.

Our old RV — which we drove away from this afternoon without a backward glance — had a solar panel on the roof. The panel charged the RVs two batteries, which, in turn could power the lights, stereo, and any devices we had plugged in to the unit’s two DC power ports. This was handy when we camped off-the-grid, as we did numerous times on our way from Washington state to Arizona last summer.

The system didn’t have an inverter, though. That meant that it could not power the AC power outlets or anything plugged into them, including handy devices like the microwave. We learned to do without.

Our New RigOur new RV is quite a step up from the old one. It actually has rooms. And a desk I can sit and work at. And lots of space.

Of course, we wanted it to have a solar setup, too. But a full-blown setup that would include an inverter and be able to power any of the outlets and devices on board. Okay, well maybe not the air conditioning, but everything else.

My husband, Mike, is a solar guy. He knows how to design solar power systems. He set up the one on our old RV and designed and built the significantly more complex one on our off-the-grid vacation “cabin.” So he sat down with a pen and paper and, using the Internet, researched a solution. We’d use the panel off our old RV, match it with a second panel, add two batteries, an inverter, and a bunch of other stuff, and have a 2KW solar setup. The cost: roughly $3K.

Now $3000 is a lot of money, especially after pouring a bunch of money into a new RV. But I like the idea of renewable energy. And I love the idea of silent energy. So I was willing to spend another $3K. I saw it as an investment in the future.

We were in Quartzsite, AZ when we picked up the RV. There are lots of RV service centers there, including two that specialize in solar power systems. So we drove over to one to get a quote.

And that’s when things started getting funky.

One guy priced up a system for us what was just a bit over Mike’s estimate. That didn’t include installation labor, though. (I insisted on a professional installation.) He quoted us labor at $55/hour for maybe four hours. I took a deep breath and nodded. So the sales guy handed us off to the order writer. She priced everything out. But suddenly labor was $85/hour and we were looking at 10 hours or more. She refused to be pinned down, but I was seeing a minimum of $4400. My “ripoff radar” — developed after years living in the New York area — perked up and started sending me signals. I told the woman we’d sleep on it and we left.

We went to the other solar outfitter. We’d bought all our solar panels and some other equipment from them in the past. They priced out our system and came up with a solid number: $4168. Ouch.

Mike and I talked about it at some length. He’d already suggested a much cheaper alternative for the times we were off the grid: a 2000-watt Honda generator that could be used parallel with an identical model to give a total of 4000 watts. If you needed a little power, you’d fire up one. If you needed more, you’d connect the second one and fire it up, too. With 4000 watts, we could power everything in the camper, including the air conditioning.

At first, I’d resisted the suggestion. I wanted quiet power. The Honda generators were known for their quietness, but nothing would be as quiet as solar.

But the kicker: we could get the Hondas for less than $1,000 each. Just one would provide as much power as the solar setup we’d envisioned. No need for an inverter or charge controller or holes drilled in the RV roof.

Yamaha EF2000iS GeneratorLater that day, we walked around the RV show in Quartzsite, where vendors were selling all kinds of things for RVers. One of them had Yamaha generators. The Yamaha EF2000iS did the same thing the Honda we were considering did, but it was 2 decibels quieter and 2 pounds lighter. And a tiny bit cheaper to buy, too.

It was even cheaper on Amazon.com.

So we didn’t go with the solar setup. I just can’t justify the added expense — after all, to get 2,000 watts with solar power, we’d be spending four times as much as the generator would cost us.

And I’m sure we’re not the only people who feel this way.

It’s unfortunate. There are many people out there who want to do the “right thing” and use renewable energy. But it’s difficult to justify the added expense. When a friend pointed out that we’d have to buy fuel for the generator, we replied that $3000 worth of fuel could go a long way at 5 hours per gallon. The solar setup would never pay for itself.

I’m hoping that changes sometime soon.
