According to a new report, Wind Power – Global Market Size, Turbine Market Share, Installation Prices, Regulations and Investment Analysis to 2020, by research firm GlobalData, installed capacity increased at a compound annual growth rate of 25%. This translates into to a jump from 73.6GW in 2006 to 280.6GW in 2012.
There was a 7%, fall in annual additions in 2010 as major wind markets such as the US, Germany and Spain, faced economic problems following the global economic crisis.
China was the global leader in wind power in 2012 with the US coming second. The US lost out on the top spot due to the economic slowdown and uncertainties relating to the future of the industry because of a lack of long-term policies supporting the wind sector.
Offshore wind power installations accounted for 1.9% of the global wind power market in 2012.
GlobalData’s forecasting from 2012 to 2020 sees the share of offshore wind in the global wind power market reaching 8.4% by 2020.

The angle or pitch of your roof actually has less impact on solar panel performance than the direction it faces. In general, optimal production occurs when solar panels face south at a tilt equal to 30°. But what happens if your roof is flat? Lowering the tilt all the way down to 5° only decreases production by about 10%, regardless of where you live. The difference in production for steeper roofs is barely noticeable. Increasing the tilt from 30° to 40°, for example, results in a negligible decrease of about 1%.
Looking at data from six cities- Boston, Los Angeles, New York, Chicago, Philadelphia, and Washington, D.C., Energy Sage estimated the production levels generated at various tilt angles. They held the azimuth constant at 180° which in laymen’s terms means they always assumed that the roof faced directly south. What they found was consistent with their investigations into the effects of other variables.

TreeHugger Founder, Graham Hill, Lives In A Mind-Blowing 420-Square Feet ‘Tiny Home.’ His home is a prototype of spaces from LifeEdited, Inc., a company dedicated to showing people how living in small spaces can actually be a good thing. In the video, we see Graham uses just 420 square feet of space to sleep, host a dinner party for 10 and even watch a movie projected on the wall. This is thanks to nearly every inch of the place being foldable or hidden. At the end, Graham pulled out one of the walls and turned it into a room divider for guests.

The aluminum-clad wood house is 8.2 feet wide by 9.8 feet long by 11.5 feet high. It features two rainwater tanks attached to a boiler, a composting toilet, triple-glazed windows and insulated walls that can withstand temperatures from minus 10 degrees to 105 degrees Fahrenheit. Electricity comes from three rechargeable batteries that plug into an external power source. Diogene is expected to be produced in three years and will cost about $45,000. A deluxe model with rooftop photovoltaic panels will be about $75,000. The prototype can be seen on Vitra’s campus in Weil am Rhein, Germany.

An experimental apartment building in Hamburg, Germany is harnessing the power of the sun to generate power, but not in the way you expect. Photovoltaic cells are totally yesterdays news — the BIQ building gathers power using a bioreactor façade packed full of microalgae.

Large clear panels on the front of the building are where the microalgae are growing. These microscopic organisms behave like any other plant. They absorb sunlight, process carbon dioxide, and produce oxygen. The algae flourish in a regular cycle, with the mature plants being harvested on occasion.

The process is highly efficient as it results in no additional carbon output, and algae produce more biomass by area than any other plant. Any light that is not absorbed by the algae can be captured by the façade and used to directly heat water or air when it’s chilly out. Failing either of those immediate needs, the heat can be piped down into borehole heat exchangers (an 80-meter deep hole filled with brine) for later use.

As much as he enjoys talking about design, what Jay Scaafer really wanted to talk about in this interview was the politics of tiny houses. Why building and zoning codes are stacked against tiny houses, how the costs of purchase and upkeep compare to the big houses he calls “debtors’ prisons”, and why, when the Big One shakes the land around San Francisco Bay, he’d rather be in his tiny house than anywhere else.

Dee Williams decided to downsize from a 1,500 square foot home to a 84 square foot home after a trip to Guatemala. She built her current home, “The Little House,” herself for about $10,000. With a propane tank for heat and electricity coming from solar panels, Williams cost of living runs extremely low.
