Oil prices reach 100 USD a barrel

2008 will see many new records for oil prices as already yesterday the price did hit $100 per barrel at the New York Mercantile Exchange (NYMEX).

Difference between behavioral change and efficiency

In my article on the clean alternatives to coal I was mentioning that the first thing to implement before any other was behavioral changes and energy efficiency.

However, some alguae like Ulva lactuca (sea lettuce, pictured left) have a much superior yield than cereals and aren’t as much eaten as
