Clean Energy in California

Lawrence Berkeley National Lab–Wed, March 11, 2009
by -- March 11th, 2009

Wednesday, March 11 began with presentations and tours of the Lawrence Berkeley National Lab (LBNL). (

Heinz Frei presented his work on Helios-SERC. (  The Helios effort comprises a solar energy initiative with the primary goal of developing methods to “store” solar energy in the form of renewable transportation fuel.  Helios SERC scientists are developing solar-driven chemical converters that will create transportation fuels from water and carbon dioxide.  Research focuses on advanced nanomaterials for use in solar light collectors and electrodes, a new generation of catalysts for energy-efficiency chemistry, and specialized soft and hard membranes for integrating the light harvesting, charge separation and fuel forming components.

Dr. Frei noted that the goal of the center is to demonstrate a solar fuel generator with 1% or greater efficiency from photon to fuel.  He discussed vibrational spectroscopy and laser photochemistry in solids, nanosecond FT-infrared spectroscopy, and his recent work in the development of inorganic polynuclear photocatalysts in nanoporous silicas for carbon dioxide reduction and water oxidation.  Following the discussion, he toured us through his lab and detailed the specific purposes and functions of the research instruments in the lab.

The concluding presentation at LBNL was given by Vince Battaglia, who discussed the battery program,  a research project “aimed at developing more environmentally friendly technologies for generating and storing energy, including better batteries and fuel cells, low-emission combustion, and better sensors and materials for environmentally cleaner sources of energy, and energy-efficient sources of light.”  (  Dr. Battaglia’s research is directed toward the fabrication and characterization of rechargeable lithium batteries. (

Dr. Battaglia kept us on-our-toes, laughing and energetic throughout his presentation.  Following his discussion, we took a brief general tour and learned the history of LBNL.  Our visit concluded with a tour through Dr. Barraglia’s lab.

    Making of solar panels!

    HI, in the present world approximately we are using 500 quadrillion British thermal units (Btu) of electricity per day. And we are spending 30% of our income towards our monthly electricity bill. According to my view every individual family can generate power by building our own solar panels. Yes, we can build our cool new solar panel at affordable cost, by following the simple and very effective book as well as video guidance of ‘How to make a solar panel’ available at In this link we can analyze some brawny information and cool projects to build the solar panels. Let us use the solar power and make the world green and cool.

    Energy Saving

    After looking over this blog post I took a look around the site. You have done a great job gathering all this information.

    Totally agree

    The possibilities are huge for residential solar energy. With the rising cost of energy solar power will only become more attractive in the future.Solar power is important to the evolution of the society. It is important for countries, such as the United States, to move away from the dependency on foreign oil and to use energy resources that are readily available. No one can deny the sun isn’t a steady resource.
