While environmentally friendly business practices are often viewed as an added cost, energy efficient lighting is one area where cost savings and environmental benefits go hand in hand. Take for instance a recent retrofit completed on a tennis court just outside of Chicago; this custom – engineered retrofit has a payback period of just two years.

Updating old and inefficient windows will allow you to recoup up to 90 percent of your initial investment within the first few years. Adding Energy Star-rated windows is thought to save you up to $500 each year in heating or cooling costs and you’ll even receive green energy tax credits for doing so.
So let’s say you have been checking out some resources online on how to make your home greener. You know for yourself that it would be a bit disgraceful for people to think that you are doing and sharing everything you can to them about rising sea levels, global warming, climate change and animal extinction. But […]
First Solar, Inc. today announced it set a new world record for cadmium-telluride (CdTe) photovoltaic (PV) solar cell conversion efficiency, achieving 18.7 percent cell efficiency in tests confirmed by the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL). The record-setting cell was constructed at the company’s Perrysburg, Ohio factory and R&D center using processes and materials – including the glass substrate – that are designed for commercial-scale manufacturing.
Traditional biofuel research has focused on improving the oil content of seeds. One reason for this focus is because oil production in seeds occurs naturally. Little research, however, has been done to examine the oil production of leaves and stems, as plants don’t typically store lipids in these tissues.
Matt Grocoff is a proven zero energy master. The “Net Zero Energy” consultant is also the creator of GreenovationTV. Now the Ann Arbor, MI homeowner and a team of engineering students from the University of Michigan are continuing a quest towards ZERO. These individuals have plans to retrofit Grocoff’s century-old Victorian house so it can capture […]
“Water is very complicated. It’s affected by large-scale issues like climate change and globalization. International commerce moves virtual water (the water it takes to grow or produce a product) from farms in Brazil to grocery stores in China and Egypt.”
Follows the Seattle Wood Solutions Fair Cross-Laminated Timber (CLT) Symposium What: The Wood Products Council’s WoodWorks program will host the first-ever US Cross Laminated Timber (CLT) Symposium February 27-28, 2013 in Seattle. CLT is now available in North America and has the potential to significantly change how wood is used across the building landscape. Attendees […]
Each floating laboratory is 25 metres in diameter and will carry 100 PV panels. Each panel will be back-to-back on a 45° incline. The islands can rotate 220° in the direction of the sun tracking it throughout the day. Their location on the water lowers its resistance, therefore increasing its effectiveness.
Extinguishing fires in the best way possible has become standard practice in arresting the rampant destruction of property. Unfortunately, the chemicals used to put out blazes are often hazardous to the environment and are proven to be anything but green or sustainable. Guest writer Natasha Sabin addresses some of these concerns. The issue Fire safety and […]
“Ten percent of the Lower 48 has been leased by oil companies. That’s more acreage than we plant in corn and wheat. Oil and gas extraction is now the dominant land use on the continent. “In short, shale plays are a peculiar sort of blessing. For sure, they’ve given us a staggering amount of […]
We received this letter and infographic from Allison Lee: “I am part of a team of designers and researchers that put together an infographic showing how bad climate change has gotten and how it’s contributing to the destruction of our planet. I thought you might be interested, so I wanted to reach out.”
Researchers from the Department of Energy’s Pacific Northwest National Laboratory will exhibit their work at the 2013 Energy Innovation Summit of high-impact energy research funded by DOE’s Advanced Research Projects Agency-Energy, or ARPA-E. The summit runs Feb. 25-27 at the Gaylord Convention Center in National Harbor, Md. Below is an overview of PNNL research that will be highlighted there.
If you live in a large metro like we do, odds are you see mostly bleak-hued buildings. Lots and lots of buildings. One thing we don’t see enough of? Greenery. Of any sort, really. (Unless you count the dog park, or rather, the patch of brown grass down the street.) We’re so nature-deprived we’d welcome […]
