Super Efficient House Uses 800 Watt Hours/Day

- Benny Powers

The Treehugger website is running some good news on an ultra-efficient model home.

This house has the conveniences of a modern house, but consumes only 800Whr on average per day. Compare this to a typical U.S. suburban house that uses 45 kilowatt hours (kWh) per day. How is this reduction possible? It’s through the strategic use of ultra-efficient appliances, daylighting, and green design principles for temperature control and ventilation.

The house also automatically turns off computer peripherals when not in use.

Wired Reviews Greenmobiles

Wired magazine has a short look at what green cars one can buy now. Specifically the technology behind the autos.

“You’re ready to kick carbon to the curb, but you’re not sure which kind of car will work best for you. With oil prices spiking, temperatures rising, and the public crying for relief, automakers are scrambling to offer consumers alternatives to pollution-spewing gas-guzzlers. Here are the specs on the best available technologies – flex-fuel, diesel, and hybrid.”

They are also reporting that hybrid technology may safe SUVs, but probably not for Londoners.

Wind Powered Boats

It looks like the more things change the more they stay the same. A German company, SkySails, is going to start selling a new style of sail to help large freighters move through the ocean faster.

“SkySails’ system consists of an enormous towing kite and navigation software that can map the best route between two points for maximum wind efficiency. In development for more than four years, the system costs from roughly $380,000 to $3.2 million, depending on the size of the ship it’s pulling. SkySails claims it will save one third of fuel costs.”

World Cup Scores!

- Adam Clare

The World Cup has scored a green goal! Sorry, I couldn’t resist such cheesy writing. Seriously though, the World Cup organizers in Germany have surpassed their own goal of making the event have a small ecological footprint as possible. One thing they wanted to reduce the greenhouse gas emissions that normally would have been released for such a large event by encouraging bike riding and riding public transit. They did more too!

“There are water-free urinals, overflow limiters on the wash-basins and electricity-saving measures, which are all things that save resources but go virtually unnoticed. The fans also don’t get to see the solar panels on the stadiums, which is a shame.”

Renewable Energy Gaining Capital

The renewable energy sector is attracting a lot of investment recently, which is great to hear. This is good news because the forces of capitalism are working in favour of our environment. Here’s some great examples of all this renewed interest in renewable energy.

Great new technological development in solar power:

“CA-based Nanosolar had raised $100 million to finance a new solar-cell factory based on an inexpensive process, similar to that used to print newspapers, and that it will make enough cells to produce 430 megawatts of power annually, is just one sign that new types of solar power are emerging as a viable alternative energy source.”

Wind power is generating interest:

“The report says wind power is the world’s fastest-growing energy source with an average annual growth rate of 29 percent over the last ten years. In contrast, over the same time period, coal use has grown by 2.5 percent per year, nuclear power by 1.8 percent, natural gas by 2.5 percent, and oil by 1.7 percent. ”

There is more evidence that switching from non-renwable energy to renewable energy will help create jobs:
