Population and the Environment


1170737
One of the big things I always seem to come back to when I am looking into all the bad things that are going on with our environment these days it that there are just too many humans! Humans do lots of bad things for the environment but one of the major issues with this is that there are just so many of us. If there were far fewer of us then the bad things we do would have a much smaller impact. 



With that thought in mind I was very interested with an article I saw in the Oct 31, 2011 article of TIME called Head Count, which talked about how the world population just hit 7 Billion, and what impacts it is having. Mainly it was a lot of interesting facts that relate to this very topic. I'll give you a few here, they are really interesting stuff!

1. In 1804 the world Population was 1 Billion. So in just over 200 years the world population has gone from 1 Billion to 7 Billion!!!

2. The world population is expected to go to 8 Billion in 14 years, and then 9 Billion in 18 years after that. Yikes!

3. In the history of the world there has been approximately 108 billion humans. That means the 7 billion alive today represent 6.5% of the total history of human population. That is a lot of humans on one planet at the same time!

4. If you put the world's current population in a population density equal to that of NYC, we would all fit in an area the size of Texas. This was actually kind of comforting in a way for me. I mean 7 Billion is way too many, but it put it in perspective that it didn't feel quite so big.

5. 19% of the world's population lives in China. It's scary to think China is one of the emerging industrial countries, and they all ready have rules in place to reduce population growth. That is scary!

6. 50.4% of humans are Male. I just thought it was interesting how balanced this was.

7. 73% of the worlds population doesn't use the internet. I get it when I think about it, but this was very surprising when I first read it. We need to increase this number so more people can read Saving Green :)

8. The US is the third most populated country at 310 million, behind China at 1.3 billion and India at 1.2 billion.

Holiday Guilty Pleasure - Christmas Lights

So if you think of almost any Christmas scene in your mind which brings that nice warm fuzzy feeling to your heart and brings you back to your childhood, you will more likely then not notice that there are at least a few Christmas lights. Now being that I'm constantly trying to do what I can to reduce my carbon footprint and save money at the same time, I am constantly walking around the house turning off lights behind my kids. I always make sure to mention that they left the light on and I had to turn it off for them so we weren't wasting power. I have to admit there are occasions where they catch a light I left, which is annoying and makes be proud at the same time.

So I am really conflicted when it comes to Christmas lights. I grew up with them. It was a holiday tradition at our house growing up to string the lights out on the front bushes and on the roof line. I remember how cool I thought it was when technology came around so that we could have the traveling lights along the roof and twinkling ones in the bushes. Cool stuff for sure. The problem is there is no real need for the lights so really I'm just wasting power to put them out there. But there has to be some joy in life right?

The happy medium for now is that I at least make sure that all the lights we are using are LED lights. This saves quite a bit of power and they don't get as hot at the old style Christmas lights so I don't worry about fires either. That's a win win for sure! I also make sure to have them all plugged into a photocell timer as well. No point in having the lights on at 2 in the morning. If someone happens to drive by the house at 2 and misses out on seeing my lights, I'm OK with that. The photocell timer is pretty cool and I picked it up a few years back for like 2 bucks. It has different settings on it, but the one I use turns on the lights when it gets dark and keeps them on for 8 hours. Really simple, and saves me money. I'm sure it's paid for itself by now!

The new things I've heard about but don't have yet is solar Christmas lights. My understanding is that there is a solar panel of some kind that you put on the roof and let it charge the batteries during the day. Then when it gets dark they kick on and run until the battery dies. I'm not sure how long they are able to run and how bright they are but for me the concept at least is the ultimate in guilt free Christmas displays! I mean if its all solar then why not put up as much as you want and run them as much as you want right? Like I say I'm just not sure how well they actually perform. If possible I'll probably buy at least one set of the solar ones this year and see how they go...so I'll report back.

I'll also put a link to all the kinds of products I've mentioned here below.

So I guess I can't always be the power grinch all the time, even though most of the time it's needed so we can save this planet, so go ahead and deck the halls. Just make sure you are at least using LED Christmas Lights!

Electricity Monitor - How to Keep Track and Save

I talk here on Saving Green a lot about how to save electricity (and power in general for that matter). Most of this stuff I talk about is ideas on ways to change your routines and habits in a way that would reduce you usage. This however is a way to track how you are doing and potentially change your usage based on solid stats that relate specifically to you and your home.

I'm talking about an electricity monitor, which is a little gizmo that you plug into your wall and then plug something into it. It will then tell you how much power you are using for that item. The key with these is they show you absolutely how much power you are using for each item you use. So you might not think your TV and all the electronics that go with it are really using that much electricity but when you put your power strip into it you are likely going to be surprised. Might make you think twice about leaving everything plugged in while you are aren't there. Or for that matter you might even watch less TV!

There are many makes of these types of devices these days but one of the first and still most popular is called the Kill A Watt. The idea is that if you know for sure how much each appliance is using for power you can find the really big drawers of power and avoid them. Or in some cases you might even want to get rid of them and replace with new more efficient options. Cost is always a factor but if you find that you are using so much more power then you would with a new one, then sometimes a new appliance will pay for itself in the first year! These are the kind of decisions a Kill A Watt will help you discover and make.

The other effect one of these electricity monitors will have it similar to that of folks who wear a pedometer. They say that people who wear a pedometer that keeps track of how far you walk, tend to walk more in a day, simply because they are conscious of how far they are walking. So they do better simply because they are now keeping track of it.

The next cool step in all this electricity monitoring is going to be down the line when all the appliances we have, have their own IP address. Then we could have an app on our phone that would show how much each item is using, in real time and over time. Once you have real time easy to access feed back that's when you'll see something that really has the power to change the way we use electricity.

Even further down the line is going to be smart appliances that actually talk to the power grid. So in the summer time if it's really hot out and the power grid is getting maxed out, then the grid can talk to your appliances to save power for a while until the load dips and can return to normal. For example you might be running your dryer and the grid is maxed out. The grid will talk to your dryer and tell it to keep running but turn off the heat for a while. If it does this for many houses in the area it can get through the tough stretch and then turn the heat back on. Impressive right? Then next piece of this is when a power plant is maxed out and an auxiliary plant will have to come on line. Sometimes there isn't anything you can do to avoid this. However it is most wasteful when the auxiliary plant is just barely needed. Again the same theory could be put in place. Turn off items in households that aren't mission critical at the moment and get through the surge and avoid having to do anything with the auxiliary plant at all! Now that is Green!

***UPDATE***

While doing a little research about electricity monitoring I came across this little gem! It is similar in theory to the Kill A Watt but it monitors the power your whole house is using, IN REAL TIME! It looks like you don't need any special electrician skills. Just basic clips at your power box that anyone can clip on. Then it transmits to a base station you can keep in a convenient location. I am definitely getting one of these babys!!!

Teaching Kids to Save Energy

I'm sure you all remember you old mad standing in the door you just walked out of saying something like, "Close the door! I'm not paying to cool the whole neighborhood!". What's funny about that whole statement is that back in the day when you father was yelling that at you electricity was very cheap. Even if you account for thing being cheaper back then electricity was still very cheap. You could run all the lights in your house for the whole month and still only owe a couple bucks.

These days there is really two facets to teachings kids about saving energy. One there is the fact that you want to pay less for your monthly utility bills. Two there is the global warming angle to teach them about as well.

Paying Less For your Monthly Utilities


Since your kids don't pay the bills they don't really care if they use a little more electricity. If you catch them young in life you can hopefully instill that being wasteful is bad, but that is the best you are really going to do until they have a place of thier own. My kids are still young and are in the range where I can get their attention by teaching that wasting is bad. But as they get older I'm thinking about reducing their allowance based on how many kilowatts we use on each month. I haven't decided what the exact parameters are going to be but it'll be something basic like this. There will be a baseline weekly allowance, let's say ten bucks. I'll then look at the bill and decided where we should be at for monthly usage. If that's how much we use for a give month then each week of the following month they'll get their ten bucks. If we use less then that then they could each a bonus up to say $12 bucks. If we use more then that it'll either cut back to $7.50, or if it's really bad then it could be $5. I'll lay out all the rules at the beginning and even show them how to read the meter so they can check where they are at mid month. It'll save me money, and they'll learn the value of a dollar at the same time. Especially for something so tough as a utility bill that they aren't going to have to pay.

Dealing with Global Warming with Kids


They are aspect to teaching kids about saving energy is the effect of their actions on global warming. We always talk about doing the right thing so that out kids will inherit a clean Earth. But this is even more direct because it's what the kids themselves are going to be doing to affect the kind of world they are going to live in.

So I would talk to the kids about all the effects that are all ready happening. Melting glaciers, change of habitats, loss of land, stronger hurricanes, moving weather patterns, etc. Then you can talk about how much the decisions they make with energy effect global warming. You can even do the math. So if you see them leave a light in their room on all day while they are at school, then you can do the math and figure out exactly how much carbon they caused to be released into the atmosphere today. Then use the method above to potentially cut into their allowance. That one two punch should really open their eyes!

Why Should We Save Electricity?


1350215For many people the reason they try to save electricity is to save money on their power bills. This makes total sense and it's what should be happening. Sure we'd all like to save the planet if we can, but really for the day to day people who are stressed and working for a living they are driven by money. They want to either make more or spend less. This is how our economy works and it's how we work. So saving money is a really good reason to trigger someone to turn off a light, or try to find more efficient appliances, or any other host of ways to try to save electricity. 


Environmental Reasons to Save Electricity


So let's say you have tons of money and you don't really care how much you electric bill is. Why not just leave on all the lights and turn the air conditioner way up and juts go crazy. Well the problem with that is that most of the power plants here in the US (and around the world for that matter) burn some kind of fossil fuel to create that electricity you are wasting. So sure you aren't actually burning the fuel that is creating the carbon dioxide in the atmosphere and creating more global warming, but really aren't you? I mean if you didn't use that much electricity then less would have had to be created and there for less fuel burned, so really you are indeed causing global warming.

Now I know there are going to be people that write in and say yes but the power plants aren't on a one watt to one unit of fuel basis. And you are right. Just because specifically you left that light on all night in the basement doesn't mean that someone at the local power plant is going to get a report and have to turn up the process. But there is a point where a power plant hits a level where either they turn up the dial, or more likely they call and turn on the auxiliary plant to deal with the additional demand.

Loss of Electricity Due to Friction in the Power Lines


Not only would be you wasting power in the above scenario but even though you don't know it you are wasting more then you actually use. Actually all of us are using more then we are actually registering at the meter. This is because electricity has to flow through power lines to get from the power plant where it's created to our house. This about the power lines in your area during winter. Remember all those birds that cluster on the power lines? Why do they do that? It's because the lines are warm. And why are the warm you ask? It's because of the friction of the electricity flowing through the power lines. As those electrons flow they cause friction with the molecules of the power line itself. Friction causes heat. There is a reduction of the amount of electricity created compared to what is delivery to homes because a percentage is lost as heat energy along the way.

It is a good amount lost to heat too. As a percentage it's about a high single digit. That might not sounds like a lot but think of all the electricity that is used around the world in a day. Imagine if that was 7% less? Think of all the fuel that wouldn't have to be spent if we didn't have to create 7% of the electricity anymore! That would make a big dent in global warming right there!

Solar Roof Shingles in the US

I've yet to jump into the solar panels on the roof idea but I am very eager. I have been hesitant for a couple of reasons. One has been the initial cost to buy and install and wire the panels. The other is that from everything I read, unless you get some really solid governmental subsidies, then the life span of the panels (25ish years) aren't long enough to repay for themselves in electrical savings. This blog is called Saving Green for a reason. Yes I am all about the environment and I want to save the planet for sure, but I want to do it in a way that will save people money too. Otherwise I believe the masses just won't do it.

So one other option that I've really been eyeing for quite a while from a far is solar roof shingles. These are roof shingles similar to asphalt shingles commonly used. However these shingles has solar panel on top of them and wires run from them into your attic and eventually wire into the grid to save you money on your power bill. I really just think this is a great idea.

Well I noticed on a blog today that they are going to be come largely available in the US for the first time in 2012. They are going to roll them out in Colorado with many more states coming by the end of 2012. Check out some of the details here.

Apparently these shingles' solar panels are made of a less efficient type of solar panel without the silicone. The bad news is they are less efficient but the good news is that they are much more durable. So they can take the beating of being walked on and a hail storm now and again. And since you are going to cover your entire roof edge to edge with them then you are still going to get a good amount of electricity from them.

One nice side effect is that since these panels are soaking up the sunlight they are also keeping that heat from transferring to the roof below them. So you are going to use less power to cool your house anyway.

In the long run I'm not sure that these shingles will become more widely used then regular panels but I really think they have the cool factor down! I did see someone mention that because each shingles is it's own panel then there are obviously going to be a lot of electrical connections on your roof. That alone is fine but the problem is there is a high change of needing lots of maintenance as those connections begin to fail with time.

Over all I think solar of any form is a great idea and I really want to push in that direction myself. In the next couple years I hope to buy the house that I'll retire in, and hope that the cost of solar panels/shingles will have come down to a point where it makes financial sense as well as green sense too!

Waste Reduction


1350711


Reduce, Reuse, Recycle. It's the first one!

There are a lot of things we can all do day to day to help the environment in many different ways. One way that tends to get overlooked quite often is just reducing the amount of everything that we consume. Not only does it keep stuff out of landfills, but it also reduces the amount of stuff that needs to be manufactured. This cuts down on impact on the planet at so many steps along the way!

This about all the stuff that you by and how much packaging came along with it. Christmas night at my house is always spent patching up cuts on my fingers from trying to open those plastic clam shell packages. I wouldn't miss them at all. Stores love them because they display the products nicely and cut down on theft. However if we at a population stopped buying products that came in this kind of wasteful packaging stores would change their tune very quickly!

Thinking of how to reduce the amount of waste we create can be overwhelming but there really is one very easy way to track it. Start paying attention to how full your trashcan is each week when you bring it out to the curb. Make it a game with your family to try to make it as empty as possible each week. First try to get all the stuff you can into the recycle bin instead. Then start expanding the ways you can put less in your trashcan. Extend it out as far as your shopping habits. If you have two options for a product you need and one comes with less packaging then choose it.

I remember watching a documentary a few years ago where a women said that should could put everything that she throws away in a year into a coffee can! Can you imagine?! She was really committed and I'm very jealous. She did her food shopping at an organic co-op. She obviously used canvas bags to bring her goods home. She would bring containers with her which she was reusing and would use them to buy her bulk food. She would make sure any containers she did need to buy could be recycled. She would also sometimes make the hard decision sometimes that even though she wanted something she just couldn't find an option that didn't include way too much wasteful and unneeded packaging, so she wouldn't get the product. Maybe she'd wait a few years until the product was in the market for a while and then try to find it at a garage sale or Craig's list or something like that.

Once you really start thinking about the stuff that you throw away and how you can maximize waste reduction it gets to be a game. It's always disappointing me to on garbage night to have a can overfull. The good news is that there are weeks when it's so empty that I really wonder if it's worth putting the can out. Now I just need to figure out how to do that every week!
