Solar Community in Calgary

solargarage A subdivision in Calgary is Canada's first solar neighborhood. The Drake Landing Solar Community is a newly built community of 52 homes. 90 percent of the community's power for heating and hot water is expected to cheapest propecia online be provided from solar panels. 

The system uses a shared solar collector array that spans across the detached garages. Heat is collected and then stored in a community Energy Centre in short term storage thermal tanks, as well as in geothermal storage using boreholes. Common heating for the community is then provided by pipes running below ground from the Energy Centre to each home.

The homes in this community are also at least 30 percent more energy efficient than the average Canadian home, which helps make such a project feasible.

Solar Panels on generic viagra in us Your House, Absolutely Free.


Yup, that's right, there's a company in Colorado that will put solar panels on your house at absolutely no cost. Of course, those solar panels will be their's not yours. If you sign up for their 25 year plan, you don't even have to put down a security deposit!

The deal, then, is that you get to use the levitra 50 mg tablets green power from your solar panels, but you have to pay the company, Citizenre, for it. The good news is that you only have to pay the average cost of energy the year they install the panels. So, basically, it costs you nothing, you pay the same amount for the energy as you paid for the dirty energy from the coal plant, and you're sheltered from price increases.
Citizenre gets several strange things out of the deal. First, they're starting up their own manufacturing plant to create the panels they'll be installing. The plant gets tax credits that Citizenre won't need, and it will be selling those credits off. They also will be making money of subsidies provided for solar manufacturers and, in the end, intend to make more off each solar panel than they put into creating and maintaining it.

We truly are approaching cost-effectiveness for Solar. And since it's a hassle to find big plots of land for giant solar farms, leasing out rooftops is a logical step.

It's a strange plan, and one that will only work in sunny places with good solar subsidies. Citizenre, for example, doesn't work outside of Colorado, so most of us will have to wait on this one.

Solar Powered Cell Phone


Untested Prototype Alert! We get skeptical around solar powered portable gadgets. The sad fact is, most gadgets spend their days in bags and pockets and, if they're portable, they rarely have enough surface area to create a significant amount of charge. But, as panels get more efficient, and gadgets get less power-hungry, it might, someday, be a possibility.

So we're bringing you this tiny prototype phone from Docomo. It's billed as a 'hybrid' solar phone which, I think we can assume, means that it's mostly reliant on being plugged into the wall. But that the solar panel might give you the extra two minutes of talking time you need if you're in a jam. On the whole, the prototype is very cool, with a fairly large color LCD and an unheard of form factor, but I think we're gonna have to wait for viable, self-contained solar power in a phone.

Photovoltaic Thermal Getting its Big Break

pvtMillenium Solar, an Israeli PVT (photovoltaic thermal) company is preparing to build a 20 megawatt power plant in South Korea. PVT technology basically just combines to two main applications of solar power (electricity generation, and water heating) to make them both more poweful. As silicon photovoltaics heat up under the sun, they dramatically lose eficiency. But if there's a built in hot water heating function, the hot water carries away the heat and cools the solar cell, making it more efficient.

PVT systems have been implemented in small scale projects...houses, hospitals, etc. But there has never been a full-scale power generation plant created using PVT. The increased efficiency means that PVT can sell it's electricity for as little as 10 cents a KWh and still make a profit. South Korea is, in fact, subsidizing the plant, and will be purchasing the power at 60 cents a KWh, which sounds, to me, a little bit like taking advantage of a solar-friendly government.

$20 Solar Charge Takes Care of Business


A while back there was a cool post by my friend Justin who blogs at TreeHugger and MetaEfficient.  Seems he scored himself a Solar Style pocket charger on EBay for $20 and has a lot of success powering all of his electronics with 100% renewable energy.  The charger provides enough power to charge anything up to the size of a laptop computer. And, for an extra $30, a less portable version would provide more than enough power to juice up a laptop during use.

Solar panels are getting cheaper and gadgets are getting less power hungry.  It's easy to see where this is headed, and Justin's post is only an early example.
