Chinese Power Grab: Wind Energy Typhoon Continues This Year

November 3, 2009

China has added wind energy at a shocking pace this year, despite the slowing global economy.

Chinese wind farm construction maintains a rapid pace

The country added 93 wind farms through the first three quarters of 2009, according to Industrial Info Resources. That brought generating capacity of 15.9 GW. Another 5 GW is possible by the end of the year.

The nation is catapulting itself to a global leader. At the end of 2008, it was number four in the world with 12 GW of capacity. That position isn’t likely to last. The target is to reach 300 GW by 2010 and 1,000 GW by 2020.

Analysts say the expansion of wind energy has been 100 percent annually over the past three years.

It also has been benefiting local companies. The country has required that 70 percent of wind turbine components be produced in Chinese factories.


Not The Bogeyman Cap And Trade Could Stimulate Economy

November 3, 2009

The cap & trade bill making its way through Congress has been called most every name in the book: job killer, factory outsourcer, economic disaster.

But the legislation is unlikely to produce any of those outcomes, if experience in Europe is a guide. In fact, many companies in the states could find economic benefit, says David Hone, senior climate advisor at Shell.

Many companies in the U.S. could benefit, says Shell's David Hone

Shell, an oil company, is one of a handful of firms facing million in higher costs if a cap & trade bill limiting carbon emissions is passed. So Hone’s favorable comments should carry particular weight.

In an interview on an MIT Technology Review Webcast, he said one particular benefit to companies such as Shell is the creation of a market price for carbon. That will enable companies to invest in new technologies – carbon capture, for instance – knowing the long-term costs.

Hone said he anticipates a bill will be approved. Republicans have raised a wall of opposition in Congress, with some opponents having claimed they disbelieve in global warming and its impact.

“If 27 very diverse countries in Europe can reach an agreement, then 50 states can do the same,” he said. “If we don’t pass a bill, the issue is not going to go away.” In fact, the regulation of greenhouse gas emissions will likely fall to the EPA, a less appetizing alternative to businesses.

In Europe, cap & trade has proved an efficient method for creating a price of carbon at the “lowest cost to the economy,” Hone said. At Shell, this has served to accelerate efficiency projects and the use of carbon capture technology.

“Cap & trade sends a price signal to the market,” he said. An established price should have a positive impact on many companies in the U.S., he added.


Tidal Energy Industry Facing Do Or Die Project

November 2, 2009

Tidal energy pioneers will take a critical first step toward harnessing the powerful tides of the Bay of Fundy next week in a do-or-die trial for the nascent industry.

Tidal engineers have yet to prove electricity can be harnessed reliably and cost-effectively from the ocean’s tides. However the potential is high. The concentrated and predictable nature of tides makes the energy they produce less expensive than solar or wind.

The Bay of Fundy's Minas Passage will be the site of a critical tidal energy test statting next week.

Testing in this most dramatic Bay of Fundy environment will be crucial. Tides in the bay run higher than anywhere in the world – typically 55 feet – and storms are frequent.

According to Roger Bedard, ocean energy leader at the Electric Power Research Institute, “if this project is not successful, it would be a major blow to the industry and the industry may not survive.” An EPRI study paved the path for the Bay of Fundy effort to begin.

The trial will kickoff when Nova Scotia Power and OpenHydro of Ireland place a six-story-high turbine in the Minas Passage. The $10 million offshore turbine will the largest installed in Canada. The passage, on the east end of the bay, contains some of its strongest currents.

In the spring, two other turbines from Clear Current of Vancouver and UEK of Annapolis, Md , will go in when a new cable is in place to carry the electricity. The use of separate turbines is important because the industry has yet to settle on a single technology. The trial will help determine which of the machines under development will prove best.

According to the EPRI study, the cost of electricity from the facilities should be competitive – or equal to Nova Scotia’s present wholesale price of 5.5 cents a kWh

And it could be abundant. The tidal flow has the potential to produce 1,013 MW of power, about 152 MW of which can be extracted without no environmental impact

Nevertheless, the challenges are significant. Maintaining turbines in the harsh, corrosive salt-water environment is no day at the beach.


Computing Paradox: More Memory, Less Power

November 2, 2009

Windows 7 is the operating system likely to rescue Microsoft’s mojo in the PC software business.

Windows Vista was largely a failure. Windows 7 is likely to encourage the widespread replacement of aging Windows XP computers. (This is true despite a market study this weekend from Net Applications suggesting it is not denting the steady expansion of Apple’s Mac OS X).

New chips, less power, says Samsung

Windows 7 also is enabling another first: PCs that uses less power and run more memory. Here is a calculation released Monday from memory maker Samsung.

The company’s DDR3 memory chip manufactured at 40 nm can cut power use by 60 percent compared with the previous generation a DDR2 chip made at 60 nm.

Coupled with Windows 7, which has its own power management features, power savings are significant while memory capacity doubles to 4 GB from 2 GB.

The paradox illustrates the efforts modern chip designers have made to improve energy performance.


Tech Price Watch: Motorola GPS For $79 At Target.com

November 2, 2009

First major brand GPS at such a low price

Just like the Insignia Blu-ray disc player a week ago, this is the first time I remember seeing a GPS from a major brand – in this case Motorola – for such a low price: $79 at Target.com with free shipping (almost half the original price!).

So far the big brands like Garmin, Magellan or TomTom managed to keep prices relatively high, at around $100.

Again, this bodes well for the Thanksgiving week where I anticipate GPS devices to go as low as $50, even through online retailers. At this price, there will be no reason not to have one in your car!
