Generating electricity by harnessing the power of the wind in the most stylish possible way, here’s another rooftop wind turbine that offers a cost effective energy source for domestic, community and industrial use.

Designed by Cascade Engineering to be environmentally  sustainable, the Swift Wind Turbine uses a variety of patented technologies that makes it both safe and silent, and has a very sleek aspect. As for how effective it is, in just four years it becomes carbon and energy positive.

Aesthetically pleasing, the wind turbine is suited for both urban and suburban settings, and features a system that makes it easy to install and operate for every user. Here are more specs about it:

• Blade/Ring Diameter: 7 feet
• Minimum clearance from roofline: 2 feet
• Rated power output: 1.5kW @ 14 m/s
• Annual Power Supplied: up to 2000 kWh
• Electric power: 240VAC, 60Hz output voltage
• Noise: less than 35 decibels for all wind speeds
• Quiet mast mounting technology eliminates unwanted vibration to building/home

The Windspire vertical wind turbine by Mariah Power is a noiseless way of powering your own home for cheap in a sustainable way. Using wind power to spin, this 29.5-foot-tall vertical axis wind turbine (VAWT) it outputs 1.2 kW, will cost you some $5,000 and is able to provide 25-30% of the power needed in a typical house. Looking quite attractive it also packs a Wi-Fi transmitter so that you can monitor it online using your own computer. Count the 30% government rebate to the whole thing and you’ll end up with quite a deal.

Meanwhile Mariah Power is working on a larger 3 kW Windspire that – they say – will supply most of your house needs. – via Dvice

Tokyo has its eyes on weaning electric, gas, and petroleum companies from fossil fuels. The Japanese government will require the big users to utilize certain amounts of nonfossil fuels – solar, hydraulic and nuclear power.

The goal is for the proportion of nonfossil fuels to be 30% of the total energy supplies in Japan by 2030. It was 18% in 2005. Japan’s Ministry of Economy, Trade and Industry will overhaul a 30 year old law to promote the development and use of nonpetroleum fuels.

Japan wants to:

1. stop relying on foreign oil

2. fight global warming

3. and to reduce dependence on natural gas, coal and other greenhouse gas generators.

Energy companies already are required to use solar and wind power. Under the new law, nuclear power will be a requirement as well. Which country will be the next to follow suit?

This is the construction timelapse of a big PYCO 1 megawatt wind turbine that was built from March 31st 2008 to April 4th 2008 in Lubbock, Texas. Sooner or later we will understand that we can live a life on renewable energies if we stop wasting and though they build bigger mills around the world this is a good step forward.
