Charles Morand I received a press release yesterday about a new Emerging Energy Research (EER) study on wind power installations in the US for 2009 and beyond. EER argues that US installations could be down as much as 24% in 2009 from a record 8.55 GW in 2008. While utility-led projects remain mostly on track, smaller IPPs and developers that rely on project finance or other forms of external financing are finding the current market environment challenging. However, record growth could return as early as 2010 with 9 GW...

Comparison of Energy Storage Technologies from Solar 2009 Tom Konrad, Ph.D. A reader and  CEO of a fuel cell startup sent me an email asking for a copy of my presentation comparing energy storage technologies which I referred to in last months article on Renewable Energy integration.  Since other readers may be interested as well, here it is: Economic Comparison of Electricity Storage Technologies (Power Point Show, 721 kb) Here is also the spreadsheet where I gathered most of the data for the graphs. (Excel spreadsheet 74 kb) Visual Comparisons These following graphs can also be found in the...

Tom Konrad, Ph.D. The current rally from the March 5 bottom has been breathtaking, especially in Clean Energy, with my Clean Energy Tracking Portfolio up 70.5% since it was assembled at the end of February (as of May 1), 11% higher than it was at the three month update last week, and the S&P 500 is up 41% from its March low.  Even in a better economic climate, gains of this magnitude would have me running for cover.  In the current economic climate, with a gigantic mountain of debt keeping consumers out of the stores, makes me feel this...

Charles Morand In October 2007, Tom wrote an excellent overview of the geothermal power sector. By way of recap, geothermal power produces electricity by using steam from naturally-occurring Earth heat that travels up from the planet`s mantle and core by conduction. Conventional geothermal harnesses hot water and fluids already present in the rock while enhanced geothermal systems (ESG) - or next-gen geothermal - works by injecting cold water into hot dry rock (HDR) and pumping out resultant hot water and steam. In terms of business risks, geothermal stands at the confluence of mining and utility/independent power...
