Using Solar Energy To Reduce Global Warming

In the Department of Energy’s Argonne National Laboratory are conducting basic research on the three routes of solar energy conversion, is creating the next generation nanostructured solar cells using sophisticated atomic layer by replacing titanium dioxide sackcloth, the former with a higher cost than the latter.

The artificial photosynthesis program imitates nature using simple chemical components to convert sunlight, water and carbon dioxide directly into fuels like hydrogen, methane and ethanol. The program on thermoelectric materials takes heat from the sun and converts it directly to electricity.

Solar energy has the potential to reduce greenhouse gases as well as increasing energy efficiency, says a scientist in the U.S. Department of Energy’s Argonne National Laboratory, in a report published in March 2007 issue of Physics Today.

At present between 80 percent and 85 percent of our energy comes from fossil fuels. Since these finite resources are distributed unevenly beneath Earth’s surface.

At the time that fossil fuels are converted into useful energy through combustion, producing environmental contaminants that are detrimental to human health and greenhouse gases that threaten the global climate. By contrast, solar resources are widely available with the addition of benign environmental and climate, making it an attractive alternative energy source.

Sunlight is not only the most abundant energy resources on Earth, is also one of the most versatile, converting readily to electricity, fuel and heat, Crabtree said, a scientist at Argonne National Laboratory. This is why we should be using solar energy to reduce global warming. The challenge is to increase its conversion efficiency factor of five or ten. This requires understanding the fundamental conversion phenomena at the nanoscale. Just scraping the surface of this rich research field.
