Wind Could Power 20% of US Grid by 2030

Palm Springs Wind Farm

Here’s some interesting news: a new Department of Energy report claims wind turbines could generate 300 gigawatts of electricity — roughly 20% of the US electrical grid — by 2030.  There’s already a website in support of the news at 20%Wind.org.  The report doesn’t necessarily predict the future of the wind industry, but it paints a picture of what a particular 20% wind scenario could mean for the nation.  The wind industry currently produces about 17 gigawatts of electricity, so we’re talking about significant growth over the next twenty-something years.  That said, wind industry growth has been fierce in recent years and is on track to meet these numbers if growth holds pace.

OptiSolar Planning Largest PV Solar Farm in World!

Optisolar Topaz Solar Farm This is big news for the green building revolution, because a solar farm like this could power roughly 190k homes in California.  Referred to as the Topaz Solar Farm, this $1 billion, 550-megawatt plant would cover roughly 9.5 square miles, and if constructed, would be the world’s largest photovoltaic solar farm.  Hayward-based OptiSolar is developing plans for the project as we speak.  According to their current time line, OptiSolar will apply for a conditional use permit in May 2008 and begin construction in 2010.  Topaz Solar Farm would then be completed over three years.

[Video] BedZED Zero Energy Homes

You've probably already heard of BedZED, but have you seen it?  Feel free to watch a short little video about the cutting-edge community. 

BedZED is a 100-home, sustainable community in Beddington (UK) that's designed to be a Zero Energy Development.  Hence the Bed and the ZED.

Swift Small Wind Quietly Coming to Market in July

Palestra

Swift Wind Turbine is a quiet, rooftop mounted wind turbine.  Unlike some designs you’ve seen previously, this one has an outer ring and five blades.  The outer ring acts as a diffuser — the wind travels down the blades and is dispersed along the ring, therefore eliminating noise and keeping the turbine quiet.  The company estimates a noise of less than 35 decibels for all wind speeds.  The 7 foot diameter ring needs a roof line clearance of a couple feet and in good winds, can generate up to 2000 kWh of power (1.5 kW @ 14 m/s).

Solar Harvest, a Positive Energy Home

Solarharvest

There was a fantastic article in the NY Times on a positive energy home dubbed Solar Harvest.  Solar Harvest generated more electricity in 2006 than what it took from the grid, so Xcel Energy sent the owner a check for $8.45.  Nice!  Solar Harvest was built by Eric Doub and his company, EcoFutures, in Boulder, Colorado for $1.38 million, including land.
