Germany Crushes Competition in Solar Market

- Cam Proctor 2 Comments

There really isnt much more to this story than what the title title says. Germany has heavily embraced renewable energy, especially solar power, in every appliciable measure.
Lets see how….

Germany generates enough power from the sun’s rays to meet the needs of households in a city of 590 000, according to the Solar Energy Association BSW.

Last week, a solar electric power plant, billed by its operators as the world’s biggest, went into service in the southern German state of Bavaria. More than 1 400 movable solar modules will collect the sun’s rays and harness them into energy for around 3 500 homes.

Germany accounts for 60% of the world market in solar energy, with some 5 000 firms exporting one-quarter of their products in a sector that employs 45 000

Germans last year invested €3.7bn in solar energy, one of the fastest growing sources of renewable energy along with wind power and biomass. Solar energy accounts for less than 1% of the country’s energy needs, but the figure is expected to grow to more than 5% by 2020, according to the BSW.

Flushing Rainwater

- Adam Clare

Clean, drinkable water is a precious resource, so why are we flushing it down the toilet? I ask this question almost daily (no joke). Well, LifeHacker has a great comment thread going on this very question.

The thread is part of a post about how one man actually uses rainwater to fill his water toilet basin. This is a great way to do to less harm to the environment, but some municipalities in Canada don’t like people doing this though. Other parts of the world, buildings are built incorporating rainwater collection.

“Domestic potable water collection requires effort, energy, and chemicals for purification and transport. Toilets use 20 to 25% of water consumed in a residential house. Why are we flushing drinkable water down the toilet? In some other countries of the world, rainwater harvesting on a residential level is a mandatory part of building codes.”

Window-Powered Buildings

- Adam Clare

glass A company, XsunX, is producing some really enlightening technologies. They envision buildings that produce their own energy through solar power, they imagine a future where the very glass you are looking through is also powering your computer.

Glass as solar panels, this just makes sense. Office towers need power during the day, which is conveniently when the sun is up. I hope that this company makes these products inexpensive.

“XsunX is also developing an opaque solar cell that is so thin and flexible that it can be integrated into other building materials, such as roofing and siding. The possibilities are virtually endless.”

Carbon-Neutral Buildings by 2030?

- Adam Clare

A Sante-Fe based architect has started the 2030 Challenge to encourage sustainable architecture. Modern buildings are notoriously inefficient when it comes to energy use and hopefully we’ll all benefit from green buildings in 2030.

“Simply put, he challenges architects, engineers and contractors to cut the carbon intensity of buildings by 50% from the average of their peers today, 60% below peer average in 2010, 70% below peer average in 2015, and so on, until 2030 by which all buildings should be carbon neutral (zero net carbon emissions).”

Wal-Mart Wants to Sell E85

- Adam Clare

E85 is a blend of ethanol mixed with gasoline, the mixture is arguably less damaging to the environment than using just oil. It looks like Wal-Mart, who has questionable practices, is questing whether they should sell E85 at their Sam’s Club stores.

“It’s the single largest commitment to renewable fuels in the history of the auto industry – a good move for the automakers, and for the planet, too.

That’s because running cars and trucks on E85, a blend of 85 percent ethanol and 15 percent gasoline, could turn out to be a cost-effective way to reduce the carbon emissions that cause global warming and curb our dependence on imported oil”
