Renewable Fuels for Alternative Energy

There has been a lot of talk about alternative and renewable sources of energy over the past decade, but some countries are further ahead in this area than others. The Germans have really taken the lead when it comes to renewable fuel sources, and have become one of the major players in the alternative energy game. Under the aegis of the nation's electricity feed laws, the German people set a world record in 2006 by investing over $10 billion (US) in research, development, and implementation of wind turbines, biogas power plants, and solar collection cells.

Germany's “feed laws” permit German homeowners to connect to an electrical grid through some source of renewable energy and then sell back to the power company any excess energy produced at retail prices. This economic incentive has catapulted Germany into the number-one position among all nations with regards to the number of operational solar arrays, biogas plants, and wind turbines. The 50-terawatt hours of electricity produced by these renewable energy sources account for 10% of all of Germany's energy production per year. In 2006 alone, Germany installed 100,000 solar energy collection systems!

In the US, the BP corporation has established an Energy Biosciences Institute (EBI) to spearhead extensive new research and development efforts into clean burning renewable energy sources, most prominently biofuels for ground vehicles. BP's investment comes to $50 million (US) per year over the course of the next decade. This EBI will be physically located at the University of Illinois Urbana-Champaign. The University is in partnership with BP, and it will be responsible for research and development of new biofuel crops, biofuel-delivering agricultural systems, and machines to produce renewable fuels in liquid form for automobile consumption. The University will especially spearhead efforts in the field of genetic engineering with regard to creating the more advanced biofuel crops. The EBI will additionally have as a major focal point technological innovations for converting heavy hydrocarbons into pollution-free and highly efficient fuels.

Also in the US, the battle rages on between Congress and the Geothermal Energy Association (GEA). Recent studies by the National Research Council, the Western Governors' Association Clean Energy Task Force and the Massachusetts Institute of Technology all support expanding geothermal research funding to develop the technology necessary to utilize this vast, untapped domestic renewable energy resource.

Supporters of geothermal energy, such as this writer, are amazed at the minuscule amount of awareness that the public has about the huge benefits that research and development of this renewable alternative energy source would provide the US, both practically and economically. Geothermal energy is already less expensive to produce in terms of kilowatt-hours than the coal that the US keeps mining. Geothermal energy is readily available, sitting just a few miles below our feet and easily accessible through drilling.

One company, Ormat, which is the third largest geothermal energy producer in the US and has plants in several different nations, is already a billion-dollar-per-year business—geothermal energy is certainly economically viable, and hopefully will eventually become a mainstream source of energy production for our country and others.

5 Advantages of Cork Flooring

When choosing the right floor for your home there are many considerations.  You want it to be durable, to be beautiful and to fit your budget.  You may also want it to be an environmentally sound decision, having the least impact on the environment.  Weigh all your options; cork flooring may be your flooring of choice.  Here are five advantages of cork flooring. 

#1.  Cork flooring is a renewable resource.  Instead of having to cut down a tree, cork is harvested from a tree without causing it any harm.  The harvesting process is actually pretty interesting; cork, made from the bark of oak trees, is only harvested from a tree once every ten years.  And it’s biodegradable, which means you don’t have to feel guilty when your flooring has reached the end of its life and needs to be replaced

#2.  Cork flooring is excellent for people with allergies and sensitivities.  Unlike carpet, which can collect pollen, pollutants and dust mites, cork is naturally hypoallergenic and mold-resistant. 

#3.  Cork also contains suberin, a natural insect repellent.  Why would you want your floor to repel insects?  Think termites…enough said, right?  What’s better than a floor that repels termites rather than attracting them? 

#4.  Cork flooring is extremely durable.  Not only does it resist the dents and scratches most wood floors easily incur, it’s also lightweight which means you can install it on any type of subfloor.  It is important to note that while cork is very durable, it isn’t kryptonite - you can gouge it.  Additionally, it is water resistant which means it won’t suffer water damage as easily as other types of floors.

#5.  Cork flooring is economical.  Basic cork tiles start around $4.00 per tile or plank and vary depending on stain choice and size of plank or tile.  And because it’s fairly easy to install, do-it-yourselfers can save a lot of money on installation.

Cork flooring has the ability to be customized to fit every lifestyle and décor choice.  It can be stained, and be installed as tiles or planks, which creates a variety of pattern options.  It’s durable, mold and mildew resistant and perhaps best of all, a renewable and sustainable product.  If you’re looking to replace the flooring in your home, consider cork.  It’s an economical and environmentally friendly option.
