Vatican Gets Serious with Solar

Solarpaulvihall

Maybe Samsø started a trend in becoming a net exporter of renewable energy because it appears that the Vatican is thinking about doing something similar.  The curvaceous roof of Paul VI Audience Hall, a building that's located right by the famous St. Peter's Basilica, has been topped with 2,400 photovoltaic panels to source energy for lighting, heat, and air conditioning.

Thoughts on Al Gore's Five-Part Plan to Repower America

Five-Part Plan to Repower America - Al Gore

I’ve always been kind of irked by the fact that President Reagan, after having the White House’s leaky roof fixed, never replaced the solar hot water panels installed by President Carter.  But it’s hard to judge him because I was barely crawling at the time — I have no idea what was going on in the collective conscious of that generation.  I mean, Al Gore mentions in Sunday’s Op-Ed in the NY Times that President Nixon established Project Independence 35 years ago with a goal to, in seven years time, develop the potential to meet our country’s energy needs without having to rely on any foreign energy sources.  Yet, that never happened and Reagan’s act, the way I see it, symbolically shut the door on the possibility of American energy self-reliance.  At least for the time being.

Air Breeze Off-Grid Wind Turbine Improves Upon Popular Air-X

Air Breeze by Southwest Windpower

If you’ve heard of the popular Skystream 3.7 by Southwest Windpower, then you’re probably familiar with their smaller wind turbine called Air-X.  Air-X was introduced in ~2001 and flew off shelves, selling over 100,000 units.  Building on the success of Air-X, Southwest Windpower recently released Air Breeze, its next iteration of the successful small wind generator.  I first noticed an ad for Air Breeze in Natural Home Magazine last September and have since seen news of it popping up everywhere.  Air Breeze was engineered to be quieter, more efficient, and more effective at lower wind speeds …

Off-Grid and Carbon Free in Samsø

Samso

A few months ago, I became interested in Samsø after reading Elizabeth Kolbert's column in The New Yorker entitled The Island in the Wind.  Then, just this week, I noticed a photo essay of Samsø in The Guardian with pictures from Nicky Bonne.  What's interesting about Samsø is that it's a producer of energy — the entire island produces more energy from renewables than it uses.  They sell the rest and have been doing so since 2003.

Putting Parking Lots to Good Use

Envision Solar Parking Garage

University of California, San Diego is in the process of installing Solar Trees by Envision Solar on the roofs of two of its parking garages.  The Solar Trees are designed to provide clean energy for the campus, shade for vehicle parking, and future infrastructure for electrical vehicles.  Each Solar Tree at UCSD will generate more than 17,000 hours of clean energy per year, which is enough to power more than four single-family homes.  In aggregate, with two parking garages topped with Solar Trees, you can imagine the power they’re generating.
