The Guide To Efficient Living
Costa Rica is a country rich with renewable energy. In fact, it gets about 99% of all its electrical energy from clean sources, and it’s aiming to be the first country to become carbon neutral (more about that below). Some of Costa Rica’s energy sources include geothermal energy, the burning of sugarcane waste and other… [Continue Reading]
Nobody’s going to put up with a compost heap in a closet. But what if you could quickly compost your organic waste with no odors or bugs, indoors or outside, with a device small enough to fit in a kitchen cabinet? Naturemill promises that its Pro Edition automatic composter will do just that, producing hassle-free… [Continue Reading]
It’s the Aptera — a futuristic car that has generated a lot of buzz lately — and with good reason — the Aperta is a very, very efficient vehicle (just check out the video: you’ll see what I’m talking about). The car’s head-turning design has a purpose: the shape is highly aerodynamic (much like a… [Continue Reading]
Wow, this is a truly non-toxic paint, and it’s going to be sold exclusively at Home Depot. It’s called Freshaire Choice, and it’s a zero VOC paint. According to the EPA, the air inside a home is, on average, two-to-five-times more polluted than the air outside. Paint is a large contributing factor to poor indoor… [Continue Reading]
Folding bikes are particularly efficient when used in conjunction with public transit. Unlike regular bikes, they can be taken easily on buses, trains or ferries. In fact, some transit systems will only allow folding bikes to be taken on board. I recently reviewed the Best Folding Bikes of 2008. An efficient addition to these bikes… [Continue Reading]
Denmark has a problem — it’s generating too much power from the wind. Currently, Denmark gets about 20% of its total electrical power from wind. On windy days, that percentage can double. The ups and downs of wind power can strain an electricity grid. In western Denmark, the price of electricity can drop to zero… [Continue Reading]
The Geobulb is an 8 watt LED light that replaces a 60 watt incandescent bulb. It generates 800 lumens of light to be exact — either warm white light or cool white. This bulb has a sleeker design than some of the LED lights I’ve seen — check out that aesthetically pleasing heat sink.
In Fukuoka City in Japan, they have an amazing building called “ACROS Fukuoka” with two very distinct sides: one side looks like a conventional office building with glass walls, but on the other side there is a huge terraced roof that merges with a park. The garden terraces, which reach up to about 60 meters… [Continue Reading]
I recently noted that Hawaii has enacted a law that requires all new homes to install solar water heaters. Eventually, Hawaii may have as many water heaters as Israel, where 90% of homes have solar water heaters installed. When viewed from above, the Jerusalem often glitters with the shine of the thousands of solar heaters… [Continue Reading]
A company called GreenCore Air has released an air conditioner than can be powered by a single 170 watt solar panel. The GreenCore air conditioning unit can heat and cool a 600 square foot room. It runs on DC power, so there is no need to put an AC inverter between the solar panel and… [Continue Reading]
