the solar bubble is about to burst and it could take many incumbent solar players down with it.

Solar power, with its promise of emissions-free renewable energy, boasts a growing number of fans. Some of them, it turns out, are thieves. Just ask Glenda Hoffman, whose fury has not abated since 16 solar panels vanished from her roof in this sun-baked town in three separate burglaries in May, sometimes as she slept. She is ready if the criminals turn up again.

It looks like a scene from an old episode of The X-Files: As a red-tailed hawk circles overhead and a wild pronghorn sheep grazes in the distance, a dozen people in dark sunglasses move methodically through a vast field of golden barley, eyes fixed to the ground, GPS devices in hand. They're searching for bodies. In this case, however, the bodies belong to the endangered blunt-nosed leopard lizard, and the crew moving through the knee-high grain are wildlife biologists hired by Ausra, a Silicon Valley startup that's building a solar power plant for utility PG&E on this square mile of central California ranchland.

Spain is one of the world's hottest markets for solar panels and Sebastian said he expected capacity by the end of this year to be five times a target of 371 MW that the government had originally set for 2010 in a renewable energy plan.

Solar energy can be utilized in various ways - to provide electricity, mechanical power, heat and lighting. Passive solar heating and cooling can save substantial electricity bills. Design of a building is very important for tapping passive solar energy. The building and windows are designed in such a way that they carefully balance their energy requirements without additional mechanical equipment. Solar benefits are utilized through windows and pumps, and fans are used minimally.

Now here’s a story that makes me feel profoundly unaccomplished: a 12 year old boy in Beaverton, Oregon recently developed a new type of 3D solar cell that makes other solar cells look inefficient by comparison.

Wind power has long been the big beast of the renewable energy jungle. The technology to generate electricity from wind has been established for more than two decades, and in the past five years has been refined and expanded towards much larger and more powerful turbines including ones that can be used at sea, and towards very small turbines that can be fixed to office buildings or houses.

The type of solar energy capture system you put on your home depends on your needs. If you want to go full tilt and generate usable electricity from your home’s rooftop – and even possibly contribute power back to the larger grid – tried-and-true photovoltaic arrays might be just the ticket. A typical installation involves the panels, which are constructed of many individual silicon-based photovoltaic cells and their support structures, along with an inverter, electrical conduit piping, and AC/DC disconnect switches.

One of the more thorny issues with any form renewable energy is collecting it. There is plenty of wind to meet our energy needs, the trick is “harvesting” it. The same goes of solar. As Cool Earth Solar’s CEO Rob Lamkin says, “If you’re going to replace hydrocarbons with solar, you’re going to need a lot of collecting surface.”

But a new Greener Homes Price Guide by the Royal Institute of Chartered Surveyors’ Building Cost Information Service claims some green upgrades are better value for money than others. One of the worst performing alternative energy sources in the guide is solar power. The guide says the cost of installing solar panels is around £4,000 to £5,000, with resulting energy savings of as little as £24 per year - meaning it would take some 208 years to pay back that initial installation cost.

Their PowerSheet cells contrast the current solar technology systems by reducing the cost of production from $3 a watt to a mere 30 cents per watt. This makes, for the first time in history, solar power cheaper than burning coal. These coatings are as thin as a layer of paint and can transfer sunlight to power at amazing efficiency.
