Ocean Power Technologies - Taking a Closer Look
Ocean Power Technologies - Taking a Closer Look
This blog post @ AEI takes a look at Ocean Power Technologies. The company, for its projects in Hawaii, New Jersey and Spain, have highly deployed power technology. One PowerBuoy produces 40kw and only in Hawaii and Spain will these wave "farms" will reach over 1 megawatt - this for a technology that is supposedly scaleable to hundreds of megawatts...
However, the post goes on to say there are good things about the PowerBuoy technology - it is modular, and add to it the fact that wave power is more predicatable than other intermittant renewable technologies based on wind or solar. In terms of costs, wave energy could cost more than wind energy but with economies of scale, within 3-5 years the costs could be the same for both...

Recent Advances Demonstrate Why Nuclear Will Win
Recent Advances Demonstrate Why Nuclear Will Win
Recently, engineers have announced some relatively simple changes that will increase the safety and efficiency of nuclear plants.
For example, a group at MIT have found that by making Uranium fuel pellets hollow, like tubes it's possible to increase the fuel efficiency by 50%, says this post @ iNuclear.
One minor change, and we get a 50% pop. That's an incredible increase, compared to what is possible in other alt energy sources. This is an perfect example of why nuclear power is the long-term winner of the energy race, argues this post

Energy, the Next Boom Industry
Energy, the Next Boom Industry
The changes in the energy industry will create huge opportunities for new technology, says the author of this post @ Alt Energy Technology.
The energy business is about to change in a big way, and its growth could dwarf the changes in the Internet and telecom businesses. Similar to what happened to the IT & Telecom businesses starting a decade ago, we can start to see the changes happening in the energy industry now. The incumbent oil companies and other energy companies like the way it is, the oil companies and will react the same way and protect their core businesses at all costs, as did the big telecom companies. By the time the large telecom companies started reacting to the changes seriously, it was too late. The same could happen to the large energy companies, feels the author.
Alternative energy has the potential of making the Internet/Telecom boom look like pocket change. Energy is a trillion dollar market and growing and any company that gets a piece of that action will do extremely well.

Spain's Wind Energy Generation Exceeds All Other Forms
Spain's wind energy generation reaches new high, exceeding all other forms
Spain's wind energy generators this week (Apr 20, 2007) reached an all-time high in electricity production, exceeding power generated by all other means...On a specific point in time this week, wind power generation rose to contribute 27 percent of the country's total power requirement - at that moment wind power contributed 8,375 mega watts to the nation's power consumption of 31,033, nuclear power - 6,797 mega watts and coal-fired electric generation - 5,081

Energy Alternatives Competing For Funding
Energy Alternatives Competing For Funding
Advocates of various sources of alternative energy are beginning to point out the competition's warts. Everyone wants to use the energy crisis as leverage to support his or her solution.
But with limited government research and development money for ways to replace oil, any technology's gain is a loss for the others. So the criticism is flying in all directions.

Fueling the Debate: Ethanol vs. Biodiesel
Fueling the Debate: Ethanol vs. Biodiesel
By Jack Uldrich, April 20, 2007, Motley Fool
This past week offered a perfect synopsis of the continuing debate over whether ethanol or biodiesel is the preferred biofuel of the future. Determining which fuel is better, though, is about as helpful as determining whether running or swimming is the healthier exercise option -- since both, of course, are beneficial. So how do they differ, and what really are the benefits of each?

Geothermal power is hot stuff
Geothermal power is hot stuff
Submitted by Jorge Sosa on March 16, 2007
George and Donna Pavelek love their renewable energy.
Since 2003, the couple have used a geothermal system to heat and cool their home. “I’m not into all this global warming (stuff) or anything,” Donna said. “It just made sense. We’re not radical by any means, just practical.”
Donna said four or five years ago, the cost-versus-payback equation on wind energy didn’t make sense for them. However, they expect their geothermal heating and cooling system to pay for itself in the next two or three years.

How Green is Nuclear Power?
How Green is Nuclear Power?
By Mark Clayton, The Christian Science Monitor
Nuclear Power is an idea that may be catching on. At least 11 new nuclear plants are in the design stage in nine states, including Virginia, Texas, and Florida, according to the Nuclear Energy Institute website.
But that carbon-free pitch has researchers asking anew: How carbon-free is nuclear power? And how cost-effective is it in the fight to slow global warming? asks this article from CSM, read the full article here @ KVOA, Tucson

Academic to argue case for nuclear energy in New Zealand
Academic to argue case for nuclear energy
NZPA | Friday, 23 March 2007
New Zealand's reliance on hydro and geothermal energy sources could be short-sighted in the face of climate change, says the European energy expert Terry Wynn, a former member of the European Parliament.
The visiting academic at Auckland University 's recently-created Europe Institute plans a public lecture at the university on the pros and cons of nuclear energy.
