home wind turbines fail to deliver: study

A British study has found that many micro, or home wind turbines, don’t deliver the energy wallop that their manufacturers’ claim.


Home turbines included in this particular study produced less than 5% of a home’s daily energy consumption, versus the 30% that many turbine manufacturers claim is possible. This study was funded by the British Wind Energy Association and the government which inspected turbines in four rural, 10 suburban and 12 urban sites for a year-long period.  The small sample size leaves the results open to question. The British Wind Energy Association still estimates that small and micro wind turbines possess the potential to produce 10% of Britain’s energy needs.  Wind turbine performance is directly related to site-specific: wind speeds, location and design.

Lexus HS 250h luxury hybrid

Lexus is launching “the world’s first dedicated luxury hybrid vehicle” later this summer.


The HS 250h Lexus will offer the best combined mpg of any luxury vehicle in the U.S., and its city mpg is estimated to be higher than the two-passenger Smart micro car (they haven’t released exact mpg estimates).  Additional green stats: about 30% of the vehicle’s interior and luggage areas will be covered with carbon-neutral, plant based, Ecological Plastic (bio-plastic). The HS 250h features: an exhaust heat recovery system, a windshield with infra-ray properties to reduce interior heat and associated air conditioning, and available power-saving LED headlamps can also contribute to improved fuel efficiency and lower emissions.  The vehicle’s aerodynamic design is intended to reduce drag, noise and increase mpg.  And, lastly, it earns a SULEV emissions rating utilizing regular 87-octane gasoline.

Loya Rossa

This post is written by Guest Blogger, Stephanie Mercado, who traveled to Argentina recently. She visited this shop a few times since it was close to the hostel, and the owner was quite friendly. “The perfumer told me lots of stories about native legends, tea and perfumes … and a little bit on how she creates her perfumes. So, we do keep in touch.”

When I discovered the Loya Rossa line, by Arkadia, I was pleasantly surprised to find out that not only does it smell fantastic, but it’s also planet friendly: the packaging is recyclable, the ingredients are biodegradable and the only synthetics used are meant to replace animal raw materials.

This line consists of three fragrances (and two that are still being developed) made from native herbs, each one representing a different Argentinean region: mosqueta rose from the Patagonia, lemon verbena (or cedrón) from the northwest, lavender from Cuyo (wine region), tea camellia from the northeast and chamomile from the Pampa. Wearing these perfumes really takes me back to my trip and the wonderful country that is Argentina.

The perfumes are sold in some top Buenos Aires hotels and in their atelier, also in B.A.  Prices may vary, but they range between 35 and 50 pesos for a 200 c.c. bottle (10 to 15 dollars).
