New wind power deal in OR

News today over at "Green Inc.", that a new deal has been struck involving a large wind power project in Oregon.  Most of the parts for the project will be/have been made in the US, and the project will have about 845 megawatts of power capacity.  338 turbines are planned, meaning each one on average has a capacity of 2.5 megawatts.

While not in total a huge amount of power for the US, this is a great step forward in clean, renewable, home-grown energy.  Now we need about a hundred more like it.

Seeing microbugs from space

Today's NASA image of the day is spectacular.  It is an image of the waters off the coast of New Zealand.  During this time of year, microscopic organisms that live in the ocean waters (phytoplankton) bloom due to the mixing of ocean currents.  When they grow in such large numbers, they reflect enough sunlight to be visible from space.  Different kinds of these organisms use different minerals to create their tiny solid shells; these end up reflecting the light as slightly different colors of blue & green.

a planet where it rains rocks

Scientists at Washington Univ. in St. Louis have found a extra-solar planet so hot that it likely rains rocks down onto a bubbling lava surface.

the man who single-handedly saved the world

About 2 weeks ago, the Wall Street Journal ran an article about Norman Borlaug, a man who's passion for farming and heart for the poor and hungry led him through a life that probably saved or even made possible millions of lives over his lifetime.  He died a couple of weeks ago and his death has gone largely unnoticed by his own country.

Discoveries of new oil increase in 2009

Today's NY Times has an article on new oil discoveries over the past year.
Several main points:

  • new discoveries are the result of substantial investments made earlier in the decade 
  • the discoveries span 5 continents & dozens of countries
  • new discoveries in the first half of 2009 reached ~10 billion barrels; if the pace continues, they are likely to reach the highest level since 2000
  • finding and extracting oil is becoming harder - requiring higher prices and improvements in technology to remain viable
  • nevertheless, world oil consumption reached 31 billion barrels of oil last year, continuing the trend of new discoveries not keeping pace with consumption, a problem that has been occurring since the early 1980's

Hubble back in business!

Arguably NASAs greatest PR instrument ever, the Hubble Space Telescope is now back in business and once again taking breath-taking, amazing, inspiring pictures of deep space.

The link above includes a video on the recommissioning process, a NASA release news story, and of course a number of new images of objects in our Universe including a gorgeous butterfly-shaped planetary nebula, star clusters, a comet crashing into Jupiter, and my personal favorite, a group of interacting galaxies called Stephan's Quintet.

Gas & Coal in current U.S. legislation

As U.S. legislators work out the new energy/climate change bill, 2 different fossil fuel industries have much to gain or lose.  Today's NY Times has an article on natural gas appearing to get the losing end of the stick compared to the coal industry.  The debate to some extent centers on which of these resources will be better in the long run for reducing carbon emissions and for maintaining a long term, economically stable energy source.

The U.S. certainly has a lot more coal reserves than natural gas, and for this reason could be seen as a more stable long-term fuel.  However, coal is without a doubt a bigger source of pollution than natural gas, whether it be carbon dioxide, compounds that cause acid rain, or toxic metals such as mercury, lead, or cadmium.  The article does not point out this fact well enough in my opinion.  It is estimated, for example, that nearly 40% of U.S. mercury emissions come from coal-fired power plants (ref).  Further, the article does not point out well enough the additional environmental harm that coal mining causes over natural gas, such as mountain top removal and strip mining.

One other disturbing point made by the article includes: 
      "Utilities that burn natural gas would earn $30 billion over 10 years in pollution credits that could be sold on the carbon-trading market. But utilities that burn coal will receive tens of billions of dollars worth of free pollution credits, savings that will be passed on to consumers but may serve to delay the closing of some coal plants."  
It would appear that Congress is not attempting to provide a fair & level playing field for the two commodities.  While natural gas can "earn" pollution credits, coal simply gets them for free.  

The article further points out that if Congress were to not pass this bill, natural gas as a power source in the U.S. will likely grow by 30%, which coal growing at only 7%.  With the new legislation being considered, however, the EPA projects that electricity generation from gas would increase by less than 1%.

water shortage in India

Today's NY Times (9-5-09) has an article on the drought that has affected India.  Here's a quote:

"the cautious optimism about the broader economy has been tempered by a historic summertime drought that has underscored the stubborn fact that many people are largely untouched by the country’s progress. India’s new economy may be based on software, services and high technology, but hundreds of millions of Indians still look to the sky for their livelihoods; more than half the country’s 1.1 billion people depend on agriculture for a living even though agriculture represents only about 17 percent of the total economy."

mining metals

Today over at Worldwatch there's an article "World Metal Production Surges" on the increase in the world's production of metals that has occurred over the last decade.  In the late 90s, a new expansion in mining of the world's metals began that has vastly outpaced anything previously.  The world now digs out a combined 1.4 billion tons of metals a year: iron, aluminum, copper, & gold, but also mercury, arsenic, cadmium, and a host of other metals that have their uses but are highly toxic.  Why has this happened?  The rapid expansion of the economy of China.  Today, China is the largest consumer of steel, consuming 36% of the world's steel.
