Take part in the “weight loss” challenge from Native Energy and you can lose 30 pounds while helping to build the greenest town in America. “Our ‘weight-loss’ challenge is a simple, fun way to get people thinking about how they can easily join in the fight against global warming.” -Regina Farrell, Native Energy
As PG&E ramps up renewable power in response to the California RPS requirement that it get 33% of its electricity from renewables by 2020; it has been exploring ways to add that much renewable power to the grid while smoothing out the ups and downs of wind energy, which often peaks at night. The utility [...]
A team of scientists from the University of Texas at Austin has developed a type of spray-on solar cells that could lower costs of production dramatically. The concept of spray-on solar cells is by no means a new approach – the Australian National University has been working on one for the past three years. The [...]
A breakthrough discovery from Sandia National Laboratories could help keep a lid on the rising cost of chemical water treatment and make clean drinking water more affordable in “water challenged” areas of the world. Working with researchers at the University of California, the Sandia team substituted one atom in aluminum oxide, a common chemical used [...]
High-tech membranes are catching on as a lower cost, non-chemical and more sustainable water treatment process, but there’s a catch: they can quickly foul with dirt and other particles. Enter NanoBrane, a nanotechnology company with a patent-pending breakthrough in membrane properties that prevents fouling. That makes the treatment process run more efficiently and reduces the [...]
We’re all familiar with the vast solar thermal power stations in the desert that use mirrors to make steam to drive turbines. Giant solar thermal arrays are already making electricity in the desert in Spain and California. But what if we could have just one of these units in the backyard, just for our own [...]
If you live in one of the states now sweltering through heat waves; even more frequent sweltering days are in your future as a result of climate change. But it’s not only your children’s children who will suffer heat waves more often. Your property values in these states will also sink over time as your [...]
The biggest commodities boom of the 20th century was a bust for water and wastewater utilities, which found themselves locked in a battle with manufacturers for vital water treatment chemicals over the past five years. Competition for more chemicals to grow biofuel crops didn’t help, either. Prices for some chemicals almost tripled between 2003 and [...]
