Iowa captures the wind

May 27th, 2011

The drive across Iowa’s nothing special. Like many places in the Midwest, the Interstate routes through the path of least resistance, so there’s not much to see except farmland.

Driving east into Des Moines a few years ago, I saw an incredible site. Dozens of massive, a couple hundred feet tall, soared out of the green and gold Iowa farmland and spun lazily on a relatively calm day. It reminded me of the massive array of wind turbines I’d seen on the big island of Hawaii a few years prior. I asked a few questions upon my arrival and learned Iowa was an early leader in capturing wind energy.

Now, Iowa gets 20% of its power form wind. According to Chris Gaul of the National Renewable Energy Lab, that’s enough to displace 6 million tons of coal a year (500 trainloads). That’s an awesome savings all because of wind. It’s with us everyday. If you live on the Great Plains (or in tornado-stricken Alabama or Missouri), you know its destructive power is swift and frequent. Thanks to Iowa, we now also know that its constructive power can change the way we create energy.

Zero Energy Buildings

January 3rd, 2011

Here’s a great idea — build office buildings that use zero energy. Sound impossible? Hardly. It’s already becoming a reality (of course, not as fast as we would like).

Zero energy building (ZEB), or net zero energy building, means a building consumes zero net energy and emits zero carbon annually.

The Department of Energy, the American Society of Heating, Refrigerating and Air-Conditioning (ASHRAE), the American Institute of Architects and the National Renewable Energy Lab are taking tangible steps to achieve this goal. The US Department of Energy launched the Net-Zero Energy Commercial Building Initiative in August 2008.

Chris Gaul, a contributor to this blog and engineer at the NREL, sent along an email about the NREL’s recent success with ZEB.

“NREL’s 220,000 square foot “net zero energy” office building is on line with part of its solar panels operational.  The graph below is revealing.  At the 4 PM starting time  the building is occupied and using less than 200 kilowatts.  People go home and during the night power demand drops to less than 150 kilowatts (kW).

“As people arrive at work in the morning demand increases to 225 kW, as expected.  Then demand plummets to less than -50 kW.  An error?  No.  The sun came up.  The rooftop solar panels are generating more electricity than the building needs.  Power is flowing to the grid and the power meter is running backwards.   As daylight ends solar power decreases and the building draws power from the grid at night.

“The trick to net zero energy buildings is to make enough power during the day to balance what is drawn from the grid at night.  NREL is installing more solar (photovoltaic, or PV) panels to achieve this energy balance.”

It’ll be interesting to see how far this can go, and how soon we can start seeing more buildings built to use zero energy.

Sunny days ahead for solar energy

September 20th, 2010

Passing along some encouraging news about renewable energy …

Solar power keeps getting more cost efficient. First Solar of Tempe, AZ, says they’ve broken the $1/watt photovoltaic (PV) module cost barrier. By 2014 they expect PV modules to cost $580/kilowatt, or 58¢/watt.

Balance of system costs, which is everything except modules, is projected to be $950/kilowatt for utility scale projects. PV modules will represent less than half the cost of a solar power plant.

It’s a huge improvement. In 2008, 1,000-kilowatt size solar plants cost $5/watt.

First Solar says they’ll sell power form their projects for 10¢ – 12¢ per kilowatt-hour.

So what does it mean? Heck if I know. I’m not an engineer. But it sure sounds like things are headed in the right direction on the green front.

And after a summer of watching Texas Tea spill into the Gulf of Mexico, I’ll take all the good news about green energy that I can get.

Dow hits an 18-month high …

March 18th, 2010

… and I end a 4 month hiatus. Not that there hasn’t been any good news to report. I’ve missed commenting on a lot. But, helping to launch new websites takes time, lots of it, so my efforts have been directed elsewhere.

Yesterday’s news that the Dow Jones Industrial average reached an 18-month high at 10,733.67 caught my attention. It seems as if few remember the meltdown of fall 2008 and spring 2009. Oh, we’re still living with the effects, that’s certain. Many people still sting from the pain of unemployment and under employment (the great, unreported statistic).

But for better or worse the Dow is like a daily cup of coffee. When it’s good, it gives you that soothing feeling. When it’s bad, you look forward to tomorrow’s cup. Somehow, seeing it rise makes everything just a little better for the vast majority. For some, it’s truly vital news that means 2010 will be better than they hoped. For others, it’s just a ray of hope.

So here’s to the Dow hitting an 18-month high. Here’s to forgetting the past and moving forward into the future. Keep looking on the bright side, everyone. And that’s not being Pollyanna. After all, there’s nothing to see in the dark anyway, so why look there?

Yano Jones: Closing the cracks & helping teens excel

November 5th, 2009

Too many times, we hear about a teen that “fell through the cracks.” So everybody shakes their heads and says, “how sad.”

Thankfully, there’s someone doing something to close the cracks. Yano Jones, an educator and athletic trainer in Omaha, Nebraska, works during the day at Northwest High School teaching juniors and seniors about how to prepare for college. Then, during the winter and spring months, he trains them on the field to help them maximize their athletic skills at the Red Zone Academy, which he founded. Again, the idea is to help them get to college, perhaps on an athletic scholarship.

Jones said most of the youth in his program at Northwest – funded by Omaha’s Bright Futures Foundation — are the ones who would normally have fallen through the cracks. Their grades are too low to really get into college, so they would just give up or never consider higher education as an option.

The athletes he works with at Red Zone Academy are much the same. They are, for the most part, pretty good athletes – not the stars – who perhaps never thought they had the talent to get a college scholarship.

And since Jones works with many kids who come from “at risk” backgrounds, it makes the work he does all the more important.

In addition to the athletic training at Red Zone Academy, Jones builds an hour of study time into each session. Plus, he shows the student-athletes some of the details they’ll have to take care of to get a college scholarship (transcripts, clearinghouses, what position suits them best in their sport, etc.).

Jones is a former standout athlete who played football at the University of Nebraska-Omaha and Wayne State College in Wayne, Nebraska, where he received his degree.

“It’s rewarding helping students who may not ever have gotten into college, the kids with 2.5 GPAs and below,” Jones said of his work at Northwest. As far as Jones knows, “no one else in the country is doing it as a class in high school, that’s what takes it to a whole different level. We’ll be with the kids consistently, every day.”

With regard to athletics, Jones says “there are kids who athletically can do it but academically don’t. They don’t take care of the little things.”

He said he hated to see potential academic or athletic talent go to waste, so he decided to do something positive.

His list of successes is long – 17 teens from his Red Zone Academy class of 2008 alone have gone on to play sports at either a 4-year university or community college.

That’s a lot of lives helped by one person being motivated enough to take time to simply patch some cracks.
