Germany generates 74% of power needs from renewable energy

Germany’s impressive streak of renewable energy milestones continues, with renewable energy generation surging to a record portion — nearly 75 percent — of the country’s overall electricity demand by midday last Sunday. With wind and solar in particular filling such a huge portion of the country’s power demand, electricity prices actually dipped into the negative for much of the afternoon, according to Renewables International.

Global wind power capacity expected to skyrocket

Wind power could generate as much as 18 percent of global electricity by 2050.

Wind energy only accounts for a small percentage of global electricity production even though we have seen more wind farms popping up over the last few years. Wind power generates only 2.6 percent of the world’s electricity, according to a new report from the International Energy Agency, but that number is expected to grow significantly over the next few decades.

Wind power tops new electricity generation in U.S. for 2012

The US remains second to China, which had 62,000 MW of installed wind power at the close of 2011.

According to the American Wind Energy Association (AWEA), wind energy was the single largest source of new electricity generation capacity in the U.S., during 2012.  With 13,124 MW of new infrastructure, wind accounted for 42 percent of all new capacity, from renewable sources or otherwise, according to a press release put out by the organization.

Underwater Turbines Could Harness a Massive Amount of Energy from the Mississippi

Underwater turbines could tap the Mississipi’s power.

Tens of thousands of turbines anchored to the bottom of the Mississippi River could someday provide more than a gigawatt of renewable energy, enough to power a quarter of a million homes. That’s the vision of Free Flow Power, a startup based in Gloucester, Massachusetts, that recently received preliminary permits from the U.S. Federal Energy Regulatory Commission (FERC) granting it the right to explore energy production at dozens of sites along the lower Mississippi over the next three years.

Windstalk – Wind Farm Without the Turbines

Windstalk

Wind turbines are an increasingly popular way to generate clean energy with large-scale wind farms springing up all over the world. However, many residents near proposed wind farm sites have raised concerns over the aesthetics and the low frequency vibrations they claim are generated by wind turbines. An interesting Windstalk concept devised by New York design firm Atelier DNA could overcome both these problems while still allowing a comparable amount of electricity to be generated by the wind.

Growing Number of Homeowners in U.S. Complain Noise from Wind Turbines Making Life Unbearable

wind turbines

The industrial whoosh-and-whoop of the 123-foot blades is making life unbearable for some.

Like nearly all of the residents on this island in Penobscot Bay, Art Lindgren and his wife, Cheryl, celebrated the arrival of three giant wind turbines late last year. That was before they were turned on. “In the first 10 minutes, our jaws dropped to the ground,” Mr. Lindgren said. “Nobody in the area could believe it. They were so loud.”

Wind Lens Floating Farms Could Boost Electricity Production in Japan

Future wind-turbine farms

The Yokohama Renewable Energy International Exhibition 2010 earlier this month revealed some visually spectacular new designs for wind turbine technology. The Wind Lens has the potential to triple the amount of electricity produced by offshore turbines according to experiments. Kyushu University professor Yuji Ohya spoke of the merits of the 112-meter diameter structures being able to increase energy output “two or three fold”, as well as being about to reduce the dreaded noise pollution so often associated with wind turbines, and improve safety too.
