@A Lyn Fei,
This issue must be addressed in terms of economics on many levels.
The investments into renewable green energies by OPEC (oil producing nations of the Middle East) has created a new era competition between East and West in the field of alternative energy research. Algeria, for example, has already invested in wind energy farm projects and America seems to be falling behind.
America's economic contracts with imports of BP (British Petroleum), however, seem to revamp the global free market's investments in energy diversification. After all, if America has the resources to export the world's highest quality convenience "fast food" consumerist companies (such as Burger King), it can find avenues to explore the profitability of creating consumer-friendly alternative energy production dollars.
Research into nuclear and green energies must therefore be complemented with active studies on East-West fossil fuel competitiveness. I believe that studies of the free market profitability of biofuels and electric energy will contribute to this contoured investigation. I am impressed that American celebrities such as George Clooney, for example, have been publicly endorsing the eco-friendly electric car.
