Methane is a gas found on most planets with atmospheres. In limited amounts, it isn’t a particularly problematic gas. In larger amounts, however, it can become a regulator of atmosphere temperatures.

Methane and Potential Impacts on Global Warming

Methane is fairly common gas found in nature. It is produced from both natural elements of the biomass cycle and artificial industrial sources. Methane is classified as a greenhouse gas and is believed to contribute to global warming.

Methane (CH4) is a problematic greenhouse gas for a variety of reasons. First, it has a long life once it is in the atmosphere, to wit, it will remain suspended in the upper atmosphere anywhere from nine to 15 years depending on climatic conditions. Second, methane is much more lethal when it comes to trapping heat in the atmosphere, being as much as 20 times better at doing the job than the much discussed carbon dioxide.

The unique chemical makeup of Methane is what makes it a problem. Once it gets situated in the upper atmosphere, it acts as a sponge for infrared radiation being reflected from the planet towards space. By doing so, it acts as a gas coat around the planet, heating us up as time passes. Since we can count on it sitting in the atmosphere for roughly 10 years, massive accumulations of methane can have a devastating impact over time.

There is nothing we can do to stop natural methane sources. On the industrial side, however, there are a lot of areas that can be addressed. The production of methane through our actions is primarily through natural gas, petroleum, agricultural, coal mining, waste water reclaiming and landfill systems. All produce methane to a certain degree, some on a very large scale.

Building and living “Green” is good for your health, conserves energy and protects the environment. Log homes are the original green building solution made directly from the earth’s natural resource. This abundant, beautiful and renewable natural resource is 100% green.

Building green is a hot topic among building professionals and consumers – for good reason. The exposure to toxic chemicals in our every day lives is resulting in significant increases in asthma and respiratory illnesses, skin problems, migraine headaches and any number of health related problems.

Since we spend much of our time indoors, it is critical that our indoor environment is healthy and safe. Many building products today are made of man-made chemicals and emit high levels of VOCs (volatile organic compounds). Health experts are becoming increasingly aware and alarmed that these man-made chemicals are showing up in our blood and lungs.

Logs are 100% natural and don’t emit VOCs or other pollutants. Soil, water and air combined with the energy from the sun, in a miraculous process of photosynthesis, are everything needed to make a tree grow. From an ecological point of view, solid wood is the only building product that is renewable, biodegradable, recyclable, energy efficient and extremely beautiful. Logs and other solid wood, as basic building components, generate the least amount of air and water pollution, emission of greenhouse gases and solid waste. For example, steel and concrete require 2.4 times and 1.7 times more energy than wood to produce and 1.42 times and 1.67 times more airborne emissions with potential toxic or negative health effects. (The Canadian Wood Council – The Anhena Project).

Advances in forestry practices have steadily increased the supply and growth of plantation and private forests. In North America, the growth of new forests has outpaced the demand and can remain at a sustainable rate. In the long run, sustainable building products that are ecologically friendly are the only viable answer to a cleaner environment.

With energy costs on the rise and no end is sight, it makes good economic sense to design and build with conservation in mind. There is a great deal of documented evidence supporting the energy efficiency related to the construction of log homes. Studies conducted by the National Institute of Standards and Technology (NIST) and other testing organizations have compared log homes to other types of construction such as conventionally framed and masonry. Test results prove the energy efficiency gained through the thermal mass of solid wood walls. Log walls better utilize the available energy in both summer cooling and winter heating.

Both now-discarded Lamarckism (the supposed inheritance of acquired characteristics) and Evolution Theory postulate that function determines form. Natural selection rewards those forms best suited to carry out the function of survival (“survival of the fittest”) in each and every habitat (through the mechanism of adaptive radiation).

But whose survival is natural selection concerned with? Is it the survival of the individual? Of the species? Of the habitat or ecosystem? These three – individual, species, habitat – are not necessarily compatible or mutually reinforcing in their goals and actions.

If we set aside the dewy-eyed arguments of altruism, we are compelled to accept that individual survival sometimes threatens and endangers the survival of the species (for instance, if the individual is sick, weak, or evil). As every environmental scientist can attest, the thriving of some species puts at risk the existence of whole habitats and ecological niches and leads other species to extinction.

Light Emitting Diode or LED lighting has been in existence for many years, mainly in niche applications like small trinkets and indicator lighting. However, due to LED lighting being highly energy efficient, not to mention technologically superior over other light sources such as incandescent and fluorescent lighting, it is forecasted to reach beyond electronic applications into commercial and home LED lighting as well. In a recent report by Global Industry Analysts it is predicted that the market for fluorescent and LED lighting could climb to $97 billion by 2010. The spike in growth would be mainly from construction and industrial development industries.

As more individuals become aware of the energy efficiency of LED lighting, the price of such items as LED bulbs will decrease in price. Currently, the price of one LED bulb is substantially higher than the price of incandescent or fluorescent lighting. However, the initial price for LED bulbs would more than pay for itself in the long run. On average, one incandescent 60-watt bulb lasts 1,000 hours whereas one 2-watt LED light bulb lasts 60,000 hours. Therefore, one would need to purchase 60 incandescent bulbs for every one LED light bulb.

Home LED lighting is a cut above the rest when it comes to energy efficiency. As compared to incandescent lighting, LED lighting wins hands down where energy consumption is concerned. For every 60,000 hours of usage, incandescent lighting uses approximately 3,600 kWh of electricity where LED lighting uses 120 kWh. Bottom line: energy efficiency equals a significant cost savings. LED lighting gives off directional light. Therefore, it is useful as a source of light for reading or spotlighting in the home. Its powerful light output also makes it great for outdoor floodlighting and path illumination. LED bulbs are now available that can replace most halogen or fluorescent light bulbs used in the home.
