Huge potential for solar energy generation in outer space

Monday, June 2nd, 2008


The concept of space solar power has been receiving a lot of attention lately.  The commonly noted problems of skyrocketing energy prices and global climate change have caused the revisiting of many previously passed upon energy solutions, including SSP.  The basic premise of SSP is that satellites holding massive solar panels would be put into orbit, where they would redirect the sun’s rays to a receiving station on Earth that would process it into electricity.  From their perch above the atmosphere, these solar satellites could generate power 365 days a year.  While the concept of space solar power has existed since 1968, it has only regained momentum as of late, due to current economic and environmental issues. 

Apparently, if an array of solar satellites were put together to form a one kilometer wide band of panels, there would be enough energy generated in one year to exceed all of the known recoverable conventional oil reserves on Earth.  However, not surprisingly, there are a number of technical hurdles that must be overcome, including the lack of an efficient means of getting all of the necessary equipment into space, given our aging space shuttle fleet.

Nonetheless, the potential for a massive source of renewable and clean energy is intriguing.  While it clearly will not be a short-term fix, given the technological and logistical hurdles to be cleared, it does sound like a promising future alternative.  Right now it appears that attempts to develop such a system will be a mix of public and private efforts.  It will be important, as a leading space pioneer, that the United States takes a leadership role in this process, rather than being surpassed by other countries like Japan and Russia, which are also pursuing SSP.

Addicted to corn?

Tuesday, March 25th, 2008

Environmental Capital, at WSJ.com, looked at a subject we have discussed regularly here—which is: are biofuels a part of the solution, or an unintended exacerbation of the problem of global warming?

As we’ve noted previously, some recent studies indicate that biofuels, such as ethanol, may actually be worse for the environment than the fossil fuels they replace. In our discussions, we’ve usually limited our analysis to which option releases more aggregate CO2 into the atmosphere. However, the Environmental Capital post notes that some experts believe that biofuel production has resulted in a 15% decrease in oil prices. Therefore, if recent policies by developed nations to increase biofuel usage are reversed, would that result in a subsequent 15% increase in oil prices?

We find this question interesting because it presents two options that are not normally pitted against each other in such a manner. If biofuel is worse for the environment than petroleum, but its production results in more affordable oil, will we find ourselves “addicted to corn?”
