When it comes to new energy sources, NIMR better suited than NIMBY

In most developed countries, particularly the U.S. and China, fossil fuels are being consumed at a rapid rate. Our country with 3 percent of the recoverable petroleum reserves consumes about 25 percent of the world’s output of petroleum each year. Seventy percent of the petroleum we consume has been imported. Our offshore oil that will be extracted in the next 10-15 years will provide us with about seven months of our current petroleum needs.

As more and more cars are being sold in China and India, there will be even greater demand for petroleum from these two most populous countries (their combined population is over one-third of the world’s population). This greater demand will mean even higher prices for petroleum whose global output has not increased in the past three years.

While the U.S. has significant reserves of natural gas, the amount of known recoverable natural gas will be gone in 10 years at our current rate of consumption (about 20 trillion cubic feet a year). We can always hope new discoveries of natural gas will be made, but we can’t count on this more than a few more decades. We can only rely on our natural gas and those of our Canadian neighbors as natural gas doesn’t transport easily. Coal, of which we have significant recoverable reserves, will last about a century. But coal mining, particularly strip mining, relies on large amounts of petroleum fuel to operate the mining machines.

Our food supply is mostly from industrial agriculture, whose output relies on huge amounts of fertilizer manufactured with natural gas. So once the natural gas supplies begin to wane, we will be back to old-fashioned (organic) agriculture with crop rotation and planting crops that are insect resistant to offset our present heavy use of pesticides (derived from petroleum).

This is the reason why most future studies recommend a shift to eating locally, buying our produce from local farmers. Currently the food that we consume has travelled an average of a thousand miles to reach our mouths. Once the natural gas and petroleum prices get very high, industrial agriculture will fade and transport of food from great distances will drop greatly. But what about energy in terms of location?

NIMBY (Not In My BackYard) is an increasing powerful political movement in rural America and in the tri-state area. Actually, it would be better called NIMR (Not In My Region). NIMR can be seen in the opposition to both wind farms and new transmission lines. So as our fossil fuel supplies face an uncertain future, should there be opposition to new energy sources that are now available?

Wind farms rely on the wind and produce no atmospheric emissions when they operate. Wind farms only make sense in windy areas. The newer wind turbines make less noise than the early models and kill far fewer birds and bats. In the future, we will see many wind turbines in windy backyards that have vertical axes, not needing a tower. Since the wind is intermittent, there will also be ‘solar gardens,’ solar panels not on roofs but on the ground that can track the sun and generate twice as much electricity as solar panels on roofs. But the biggest new energy source locally will be biomass; biomass, unlike wind and solar, is not intermittent.

Many homes will have efficient wood burners outside their homes where burning takes place at thousands of degrees, providing BTUs at a cost comparable to current natural gas prices. The biomass will be largely from local tree plantations, raising fast growing trees that can be harvested every five years. These trees won’t need fertilizer or irrigation, unlike our current industrial crops. Our local area is blessed with abundant rainfall, ideal for tree growth. With local energy, new transmission lines or great wind farms won’t be needed.

In addition, there will be much solar heating, both of water and air and much more efficient LED lighting in most homes.

Hunter’s moon on Tuesday

The evening moon will be fullest this Tuesday evening, rising as the sun sets and hanging in the sky all night. This full moon is called the Hunters’ Moon, providing extra evening moonlight the following few evenings. The Hunters’ Moon is similar to September’s Harvest Moon.

Now featured at the Frostburg State Planetarium is StarLife: Beginning, Middle Age and End, an account of the life cycle of ordinary stars as our sun. This is preceded by SkyWatch, a review of sky events seen in your backyard through years’ end. The Planetarium is in Tawes 302 with free public presentations each Sunday at 4 p.m. and 7 p.m. Call (301) 687-7799 for a free bookmark that features a campus map showing Tawes Hall and nearby convenient free parking.

  • Here’s your chance to meet the bears

    This afternoon our weekly Sunday programs will resume at 4 p.m. in the Compton Science Center, Room 224. Compton is the large building across the Tawes Hall, set for demolition.

  • Scientists are uncovering Earth’s distant past

     Powerful telescopes can look far away (also far back in time) to learn about the early universe; earth scientists using radioactive dating and isotopic analysis can investigate the first few billion years of our Earth’s history.

  • Teachers must show what is important

    As well as teaching college, I do sessions in the elementary schools and frequent public presentations; I feel I have a good sense of what makes an impression on my listeners.

  • Students can become self-directed learners

    The last of seven principles featured in the book “How Learning Works” is influencing students to become self-directed learners. This applies primarily to what students do out of class, involving homework, studying for tests, doing papers and assignments.

  • Here’s how students organize knowledge

    The 2010 book, “How Learning Works” by five researchers in the Pittsburgh area has a wealth of insights as to how teachers can influence students to be more effective learners.

  • Here are the best sky sights through June

    Thanks to the predictive power of astronomy, here are the best bare eye or binocular sights in the first half of 2012.

  • Tawes Hall was site of many good memories

    In a few weeks, the interior of Frostburg State’s Tawes Hall will start to be gutted; in a month or so, the outside walls will begin to be knocked down.

  • Students need motivation to learn

     Most teachers from elementary to college often wonder, “How can I get some of my students motivated? Then they could learn a great deal more in class, from their readings and from their assignments.”

  • Prior knowledge can affect your learning

    This column will review the first of the seven principles from “How Learning Works,” one of the most significant books in education in recent years. This principle is “How Does Students’ Prior Knowledge Affect Their Learning?”

  • Seasons and solstices mark the year’s passage

    Many think that in winter, we are farthest from the sun. There is also a widespread belief that in summer we are closest to the sun. In truth, both beliefs are wrong. The Earth-Sun distance varies by 3.4 per cent through the year while the solar insolation (watts/square meter) at midday on a flat surface varies by 80 per cent.
