<p><a title="piezoelectricity" href="http://en.wikipedia.org/wiki/Piezoelectricity" target="_blank">Piezoelectricity</a> is a <strong>sustainable</strong> way to generate <strong>energy</strong>.  It works by applying pressure or stress to certain crystalline materials, including certain ceramics and even bone, so it&#8217;s a green alternative to burning <strong>fossil fuels</strong>.  Up to now, though, the most popular piezoelectric materials contain <a title="U.S. EPA website for lead hazards" href="http://www.epa.gov/opptintr/lead/index.html" target="_blank">lead, a notorious neurotoxin</a>.  The discovery of a lead-free material could open the door to a piezoelectric  energy future in which people generate significant amounts of <strong>electricity</strong> just by moving through the civic infrastructure, from <a title="article on piezoelectric highway" href="http://gas2.org/2009/01/05/piezoelectric-road-produces-electricity-from-traffic/" target="_blank">highways</a> to <a title="article on piezoelectric floor at train station" href="http://cleantechnica.com/2008/12/04/tokyo-train-station-testing-power-generating-floor/" target="_blank">flooring</a> and <a title="article on piezoelectric revolving doors" href="http://cleantechnica.com/2008/12/10/netherlands-train-station-features-worlds-first-energy-generating-revolving-door/" target="_blank">revolving doors</a>.</p>

    <description><![CDATA[<p><em>Editor’s Note: This post was provided by one of our paid sponsors, <a title="Ecomugs" href="http://ecomugs.com/" target="_blank">Ecomugs</a>, a company that offers lead-free mugs as a green alternative to disposable cups, while at the same time providing a healthy work environment and support system for recovering alcoholics.</em></p>
<p><img class="alignright size-full wp-image-550" src="http://go635254.s3.amazonaws.com/ecopreneurist/files/2008/08/ecomugs.jpg" alt="ecomugs are ecofriendly" width="280" height="275" />Here is good news for offices taking steps towards going green - a blossoming company in California makes eco-friendly coffee mugs featuring your logo and employee name. There&#8217;s no minimum order required, so even the smallest startups can take advantage of <a href="http://www.ecomugs.com/">Ecomugs</a> handy dual purpose - the mugs are valuable promotional tools that also serve as a highly effective way to let your customers know that you are doing your part for the environment.</p>
<h3>Styrofoam - Alarming Statistics</h3>
<p>Did you know that over <a href="http://64.233.167.104/search?q=cache:g9OSs9cU13AJ:bss.sfsu.edu/raquelrp/projects/Styrofoam.ppt+styrofoam+facts&#38;hl=en&#38;ct=clnk&#38;cd=1&#38;gl=us" target="_blank">25,000,000 styrofoam cups</a> go into landfills every year? Styrofoam makes up 25% of our landfill space and is not recyclable, so any cup you use today will still be around 500 years from now. Incinerating styrofoam is not an acceptable alternative to burying the impervious material, as it gives off over 90 different hazardous chemicals, including styrene vapors and dioxin.</p>
