In my past two blogs, I’ve outlined Google’s Clean Energy 2030 proposal for reducing carbon emissions and increasing renewable energy production in the US, and added my personal comments. Here’s a few more…let us know what you think.

• I like the fuel efficiency standard of 45mpg by 2030, although from a technology standpoint I think it can go a bit higher, considering that Europe has set the same standards for 3 years from now.  Obviously this is a behavior issue though, as Americans like large inefficient cars.  Perhaps that will change in the next 20 years though, where we will find we can eclipse this mark.

In my previous blog I outlined Google’s Clean Energy 2030 proposal for reducing carbon emissions and increasing renewable energy production in the US. As promised, I have gone through the proposal in detail and now offer my thoughts on what I like and dislike about it. As always, these issues are open to debate, and I encourage everyone to get involved, or at least to educate themselves on the subject. I will try to provide links for external sources of information where applicable. The first half of  my comments are as follows, in no particular order:

• I like that the renewable energy goals are being achieved through three main areas: wind, solar, and geothermal. Nathan Lewis at the California Institute of Technology outlines the total energy that can be potentially captured from natural resources in a series of talks and papers. Of these, wind, solar, and geothermal comprise the three largest, although solar by far is greater than the other two. With that in mind, I think the goal with respect to wind is reasonable in that the technology is currently close to maturity and is cost effective. In my opinion however, the geothermal goals seem a bit inflated considering the level of investment that will be needed for widespread implementation of enhanced geothermal systems. Globally speaking, I think solar (thermal and photovoltaic) will be the best solution, but utilizing all of our mix of resources for a near-term national solution is advisable. (Read more…)
