A new solar laser could be instrumental in the quest to use magnesium as a source of energy.

Renewable does not mean green. That is the claim of Jesse Ausubel of the Rockefeller University in New York. Writing in Inderscience's International Journal of Nuclear Governance, Economy and Ecology, Ausubel explains that building enough wind farms, damming enough rivers, and growing enough biomass to meet global energy demands will wreck the environment.

Over at The Oil Drum Robert Rapier argues biomass energy has a very limited role to play as compared to solar photovoltaics.

The fundamental problem here is that photosynthesis is not very efficient. Consider the rapeseed oil yield above. Gilgamesh made a table that is basically the solar capture/conversion to oil from various crops. The gist is that only a few hundredths of a percent of the incoming solar energy gets converted into liquid fuels. Of course some did get converted into other biomass, which could be otherwise used for energy, but generally we get a very low capture of the sun's energy for use as liquid fuels. (This exercise can still be proven by assuming the theoretical limit for photosynthesis. One must just make more assumptions and it is not as easy to follow for a general audience).

This installation is projected to produce enough electricity for approximately 1,000 California homes or 30% of Google's peak electricity demand in our solar powered buildings at our Mountain View, CA headquarters.

We built this page to monitor and share the day to day production of clean, renewable energy from our very own rooftops. Keep checking in to see how we're doing. We think the future looks bright!

Concentrated solar power (CSP) is one of the simplest potential solutions to our shared energy crisis. It works by, surprisingly, concentrating solar energy using mirrors, which heat up a solvent, which then powers turbines or stores the heat produced in molten salts for later use.

The purpose of this site is to provide a resource and to help raise awareness about renewable energy technologies, with the hope that our civilization will be able to overcome the current energy crisis through the research and development of sustainable energy sources.
