The Numbers Are In: Texas Power Consumption in 2010

People love award ceremonies.  There is something fun about seeing people all decked out in finery and regalia to receive awards of merit.  There are a few which are near and dear to my heart.  At my high school graduation, we walked proudly across the stage, accepted our diplomas, and secretly palmed off our marbles to our principal.  I haven’t lost my marbles; I know right where I left them.

My Eagle Scout ceremony was very nice with the bagpipes playing, a review of my scouting accomplishments, and a little roasting by the officials in my troop.  I skipped out on my college graduation, but I have happily attended those of my family and friends (you should know which ones you are).

We are quickly approaching the Academy Awards, and I’m looking forward to the lesser-known Raspberries.  We all like to see people of merit receive the appropriate honors for their accomplishments, whether in movies, scouts or education.

Well we have our own category to add.

Congratulations! The numbers are in for electrical generation in Texas for 2010.

Everyone who was holding their breath may now let it out.  So who are the winners this year?

Total power generation went up by 3.5% last year.  In 2009, we produced 308,278 gigawatt hours and in 2010 it went up to 319,097 gigawatt hours.  Wind energy went up 1.6% from last year to account for nearly 8% of total power generation.  Never let it be said that we are running out of hot air in Texas! Coal went up by 8% in 2010.  Hydro generated power also went up in 2010.  All the other forms of power generation went done.  Nuclear dropped by 3.6%.  Natural gas was down by about 9 %.  And all the others (PV solar, Solar thermal, bio, etc) were down by 0.1%.

August 23, 2010 was the day Texans produced the most electricity (and used it as well).  January 8 was the winter high for electrical production. January 8 was also a very, very cold day.

But how will things look in 2011?

I’ll make a few predictions.  First the amount of electricity that Texas uses will go up.  In a state with an upward population curve the amount of electricity usually goes up unless something unusual happens (like an economic downturn). Over the next few years we should see an increase in the amount of electricity generated by the new solar plants. Wind energy will also go up, again because of all the hot air in Texas. Even with this increase in solar, coal will remain the dominate electrical source in Texas.  I hope that natural gas use would go up and cause coal use to go down, but it would take a large change in the price of coal and coal plants vs. natural gas and natural gas plants.

It will be fun to look back in 2012 and see if my energy predictions came true.

Have fun and save money? Too good to be true? Not any more

You may have heard the big news. The Houston Museum of Natural Science is forming a new energy conservation initiative!

On October 9th, the Houston Museum of Natural Science will kick off its new Energy Conservation Club website. The Kick Off will include Billy B, hands on activities, information on conservation, and more! All for free!

All this to kick off what will become the central clearing house for energy conservation education, the Energy Conservation Club website.

So what is an Energy Conservation Club (ECC)? An ECC is a group formed at a school, home school, church, or other organization to help people promote energy conservation. They will promote energy conservation through actions; energy audits of home and school, experiments to show how much energy can be saved, plays about energy conservation, short stories, and energy conservation and recycle art. These are just a few ways to promote energy conservation. The sky’s not even the limit.

Do people who want to promote energy conservation have to form a club to use the website? No. We encourage clubs and extracurricular activities, but a teacher could just as easily assign her class an energy conservation project or use the materials on the website in any way. A fun energy conservation project could also be entered into the NEED’s Youth Awards. A great way to do two projects for the energy of one.

There is also nothing stopping individuals from using the website. If you just want to learn a way to save money on your electrical bill, you’re more than welcome to visit us. We would love for you to tell us about it, so we could share your stories with others and encourage them.

What exactly will the website contain? It will have energy conservation tips updated regularly to help you save electricity and money. Grand philosophical thoughts such as “Turn the lights off when you leave the room.” We explain how to read an electrical bill and a meter. We tell how a smart grid differs from a smart meter. We’ll also show you the math and calculations behind how to choose which light bulb you should use. In addition, there will be all the information you need to teach about energy, from the science of fossil fuels to alternative energy sources. And that’s just for starters! We’ll keep updating the website with the latest and greatest energy conservation news and information.

We will also tell you what conservation events are going on in the community, such as the City of Houston’s Green building tours or the next NEED workshop for teachers. Energy in the News will keep you up to date on the exciting developments in energy.

You might be wondering why were doing all this. One answer is we want children and adults to be excited about science and learning. Another reason is that because the electrical demand of the country will grow by 30% in the next 25 years, we need an alterative to putting up coal fired power plants. Another might be the deep-seated need to be responsible and use what we have wisely, which includes not using electricity when we don’t need it.

What can you do to have access to this plethora of important information? That’s the easy part. The kick off will be at the museum on October 9th and will be free. We’ll have Billy B singing and dancing (my favorite is the water cycle) and lots of hands on activities and information. After the 9th you’ll be able to access all the information for free. The choices you make today will create the possibilities of tomorrow.

Get Smart : Meter or grid?

Throughout the years there have been many different versions of “smart” electronics. Movies are full of ‘evil’ and ‘good’ appliances, from Robbie the Robot to R2-D2. And even some that are just part of the background, like most of the robots in Star Wars and Wall-E. The energy industry has also started to toss around ‘smart’ terms. Not just things like Ohm’s law or Restricted-Universe Census, but smart meters and smart grids. So what are they? Are they the same or are they different? What does “smart” mean?

First of all, smart is not an indication of how well a meter or a grid does on an intelligence test, how many times they beat me at checkers, or how well they plot to overthrow humans and use us as batteries. It has to deal with how well they respond with real time stimuli. Can the system adjust in a real time fashion; can it be run correctly by automation?

A smart meter is like any other electrical meter. It reads how much electricity you use, in terms of Kilowatt hours. The information that the smart meter can give you is far more than a Thomas meter. A smart meter can tell you in real time how much electricity you are using at any given moment. It can also show you your electrical usage over time. You can see when you use the most electricity (probably right after you come home). Armed with that data you can make informed decisions, such as deciding if you want air-conditioning to come on when you get home at 5 p.m. or if you want to avoid peak hours and have the air-conditioning running from 4 – 5 p.m. But a smart grid is something completely different.

Even though the electrical grid has been growing for over 100 years , it has yet to become smart. The current grid is set for a “use it or loose it” grid. That means that the grid should always have enough electricity to power everything that is currently on it. This creates two types of electrical generation. One is base load and the other is peak load. Base load is what is always on the grid. This is mostly created using coal fired power plants. A Coal fired plant takes a lot of energy to start up, but once you get it going it is easy to keep it going. Because of that coal fired plants are always burning coal. So when you’re at work and the refrigerator is still on, it’s part of the base load. Most of the time the base load handles all our electricity needs. However if there is a large spike of electrical usage, such as the one around 5 p.m. when most people get off of work, the base load is not enough. This is when they can bring on fast startup plants, usually using natural gas as the fuel, and supply the electricity during peak times.

The current grid is rigged for redundancy. The current electrical grid has grown up to offer multiple paths for electricity. This means that if one area of the grid goes down, the electricity can be maneuvered around the broken part. What that means in practice is that just because an area near you looses power, your power may not be interrupted.

Why would a smart grid be better? For our current grid we use mostly large scale power generation plants, but the smart grid would easily incorporate lots of small residential power generators like small solar panels on roofs and small wind turbines. The small solar panel and wind turbines on the current grid are unable to provide all your electrical needs. Even though they take in electricity all day long, they only have available what they are taking in at the moment. If there were a way to store all the electricity that they take in during the day when you aren’t using electricity, then it would help with the electricity you need, especially during peak times. Also in a smart grid, if you had an excess of electricity you could sell it to a power company. You could even sell it directly to people who need the electricity. You would go from one who can only consume, to a producer, seller and consumer of electricity.

How can a smart grid help us save money on our electric bills? Currently most electrical companies charge a single rate for electricity. That means that you pay a constant price for a kilowatt hour. The real cost of electricity is always in flux. The price has to do with what time of day it is, what season, what it was priced at yesterday, which power plants are down for maintenance, which ones have been reopened, the weather and many other variables. A smart grid would allow us to purchase electricity in real time. What if power plant B is selling electricity cheaper than power plant B at 3 a.m.? What if power plant A sells cheaper electricity at 2 p.m. than it does at 5 p.m.? Which one would you like to buy electricity from? When would you buy your electricity if you could store it? It gets even more exciting by adding smart appliances. What if you could tell you dishwasher to only wash dishes during the night if the cost of a kilowatt hour fell to a certain price? What if your water heater could find you a better price for the electricity used to heat water for your morning shower?


So is it green? What do we mean by green, it looks like cooper to me. The real question is how can this help save the environment and money (or if you’re more cynical, money and the environment). A smart grid would have the ability to allow small scale renewables to have a larger effect. In a system where a lot of electrical production would be done on residential or small communal solar cells, wind farms, tidal farms, or back yard geothermal plants, the need for large scale power plants would diminish. Large scale power plants will never be done away with. Mother Nature is far too capricious for that.

Why do we need to change the grid if it works? The electrical needs for the country are expected to grow 30 % over the next 25 years. That prediction is counting on nothing new happening. What happens if we all switch to the electric cars during that time? Gasoline prices would drop, but electrical prices would rise, because electricity would replace gasoline as the fuel of choice. Right now that would mean building more and more coal plants.

On a smart grid, with most households having some small renewable power generation, the rise in electrical need may not lead to the building of more coal fired power plants.

So how long will this take? So far it has taken over 100 years to get to where we are today. When electricity first started being used most power plants where small and only provided enough electricity for a few buildings. Over time it became cheaper and more reasonable to have power generation on a larger scale. While this would not require us to reinvent the electrical grid, it would mean upgrading all of it. And all that would take more then four years.
