I must admit, I have butterflies in my stomach. I've been invited to blog and tweet during the World Renewable Energy Forum 2012 in Denver, Colorado, May 13-17. There really aren't enough positive adjectives to describe how remarkable this event is going to be. There are 900 presentations on renewable energy and sustainability topics being presented by speakers from all over planet Earth. I was hoping that I could clone myself so that I could attend every single presentation. Here's a link to the full list of presentation titles and below is just a tiny sampling of the diverse topics at this years WREF:

• Quantum Dots, Nanoscience and the Future of Photovoltaics 
• The Mexican Earthen Roof, An Ancient Antecedent to The European Green Roof 
• Approaches for Planning and Implementing Sustainable Energy Growth in a Complex World 
• Hispanics and their Solar Energy Adoption Patterns 
• Rural Solar Electrification in Nigeria: Renewable Energy Potentials and Distribution for Rural Development 

Some of the sessions will use the "Ignite" presentation method. Speakers using the Ignite method use just 20 slides that auto-advance every 15 seconds for a total presentation time of just five minutes. The Ignite method really forces a speaker to get to the crux of the topic being presented. These Ignite sessions will definitely be fun and engaging.

I'm honored and jazzed to spend the week with hundreds of passionate people that are working towards a more renewable, efficient, and sustainable world. Won't you join us?

Grappling With a Garbage Glut

Landfill Compactor

It's the elephant in the room. It's your crazy old uncle that everybody ignores at family gatherings. We have a problem and it's related to our consumption. I say "we" and "our" because I am just as guilty of blindly consuming and watching the by-products of this consumption go out to the curb each week and get taken away to somewhere, out there, wherever that is. Out of sight out of mind.

I go to the store, buy stuff (food, clothes, electronics, appliances, home improvement items, etc.) that I think I need. This stuff comes wrapped in cardboard and plastic packaging that I typically can't reuse and I throw that packaging out if it can't be recycled. I also throw out food that wasn't eaten. All of this discarded packing and spoiled food gets wrapped up in a plastic trash bag (plastic takes about a 1,000 years to decompose) and goes off to spend the rest of its long life in the landfill. Landfills are large swaths of land where all of our discarded stuff is moved around, compacted, buried and spends the rest of its life decomposing.

This article in the Wall Street Journal speaks to us about our garbage problem. It's a problem because we can't continue to indefinitely consume and throw away the stuff that we manufacture. That behavior is not sustainable. Municipalities are beginning to grapple with the garbage problem by thinking of innovative ways to deal with all of that trash. The WSJ article shows us how European nations are "shunning landfills" by increasing their recycling efforts as well as building "waste-to-energy" plants.

Yet we shouldn't just leave the problem up to government considering that the problem is caused by every one of us living breathing humans. Each of us has the responsibility and power to solve this garbage problem. The best and easiest thing we can do, which was brought up in the last paragraph of the WSJ article, is to figure out ways to divert waste from the landfill in our homes and businesses. For myself, I've started a compost bin at home where I take all of those landfill-bound food scraps (no meat) and throw them into the bin. This compost will then be added to the soil to help my garden grow healthy vegetables for my family. Composting has reduced my weekly landfill contribution by a third. Recycling cardboard, plastic containers, glass, and aluminum helps reduce my weekly landfill contribution by at least a half. My weekly landfill contribution is now composed of meat scraps and packaging that is not recyclable. And composting and recycling are pretty easy.

There are many other things that each of us can do to help divert stuff from our community landfills, but we first need to admit that we have a garbage problem, which in essence is a consumption problem. Once we do that it will be easier to understand ways to divert waste from our landfills. What are your thoughts dear readers?
