Algae: The Energy of the Future

Esquire has a short little article outlining the top four ways that algae can be used for energy production.

Dark Fermentation
Most scientists believe photosynthesis is the key to algae oil. Solazyme sees it as the problem. Algae can convert sunlight into chemical energy, but not nearly as efficiently as other materials–industrial wastes, switchgrass, low-grade molasses–can. So Solazyme designed a process that lets algae feed in the dark on input biomass rather than sunlight, cutting down the conversion process from weeks to days. The company’s end-product diesels meet the same standards as nonalgal diesels, and it expects their price to be on par in two to three years. Until then, the company, which signed a development agreement with Chevron this year, will continue to clock miles in its algae-powered cars, standard vehicles purchased straight off the lot.

Green Your Holiday

Planet Green has some tips on how to save time and be greener during the holidays. It’s easy being green.

Be casual about the holidays.
The holidays are about spending time with the family not getting all decked out in formal gear and having a five star meal. Spend Christmas at home with your family and instead of your holiday best, wear PJs and relax. Assign each family member a dish that can be prepared ahead of time so you won’t be a slave to the kitchen for hours and hours.

Europe’s Biggest Wind Farm Turned On

Today Portugal turned on its offshore wind farm, the wind farm will provide energy for up to a million people.

A total of 120 windmills are dotted across the highlands of the Upper Minho region of Portugal as one of western Europe’s poorer nations continues to forge its reputation as a renewables champion.

“Europe’s largest onshore wind farm is now fully operational,” a spokeswoman for France’s EDF Energies Nouvelles, which co-owns the farm, announced this morning.

The two megawatt turbines on each windmill deliver electricity to a single connection point with the electricity grid and should supply around 1% of Portugal’s total energy needs.

China’s Green Lining in its Stimulus Package

Lots of countries are handing out stimulus packages to try to stop economic turmoil. It’s great to see that China realizes that the future of the economy is green. China is investing in knowledge-based employment and green infrastructure.

For several years, the Chinese government has been sponsoring a shift from energy-intensive to knowledge-intensive jobs and economic activity. China’s recently-announced $586 billion stimulus package (Rmb4,000bn, £380bn) will transform its economy even faster, by promoting economic restructuring and essential green infrastructure.

The slowdown makes this transition all the more urgent, because GDP growth in China’s service sector produces more jobs than does the industrial sector. With recent GDP growth rates above 10 percent, China’s heavy industry generated enough new jobs.

But with slower growth forecasts, continuing large cohorts of high school and college graduates, and its rural population moving to non-agricultural employment, China needs to generate even more jobs from its economic investments.

Many details on China’s stimulus package have yet to be released, but what we know so far is promising. It includes 12 percent for direct energy efficiency and environmental improvements. In addition, the programs doubles—to $85 billion—investment in rail transport (a lower-carbon alternative to road and air transport), and adds $70 billion for new electricity grid infrastructure.

New, more flexible and sophisticated grid infrastructure is vital to increasing the efficient use of both traditional fuels and renewable energy sources. Furthermore, the stimulus package promises considerable investment in health, education and rural services. These sectors are both less energy intensive and strong on promoting jobs and welfare.

How to Build a Reciprocal Roof

I’ve never built a roof before, but now I want to build a reciprocal roof. Go ahead and take a shot building your own roof!

What is a reciprocal roof?
A reciprocal roof is a beautiful and simple self-supporting structure that can be composed of as few as three rafters, and up to any imaginable quantity (within reason, of course). Reciprocal roofs require no center support, they are quick to construct, and they can be built using round poles or dimensional lumber (perhaps with some creative notching). They are extremely strong, perfect for round buildings, and very appropriate for living roofs, as well. The reciprocal roof design was developed by Graham Brown in 1987.
