The exception would be if you have an international flight, and are making the connection in a different country than you started in, then you may have to clear customs at the connecting airport rather than the final destination.n that case you have to get your bags, clear customs, re-check your bags (or at least drop them off at specific location, depending on the airport), and clear security again. When the airline tells you to check in 2 hours before departure, they mean it regardless of whether you're checking bags or not.
Wind energy is one of the fastest growing sources of electricity in the world. The United States surpassed Germany last year to become the world leader in wind energy installed; 121,188 MW of wind energy were installed globally by the end of 2008, with that number expected to increase to 152,000 MW by the end of 2009.
This, and the fact that wind power is one of the most abundant and increasingly cost-competitive energy resources, makes it a viable alternative to the fossil fuels that harm our health and threaten the environment. Wind energy is the fastest growing source of electricity in the world. 2008 comprehensive study by the U.S. Department of Energy found that expanding wind power to 20 percent by 2030 is feasible, affordable, and would not affect the reliability of the nationâs power supply.
