Cuban leader Fidel Castro warned Tuesday that the world is close to an energy crisis due to " unbearable waste of energy" in the North.

Upon arrival at the Venezuelan city of Puerto La Cruz, some 300 km east of Caracas, Castro said the "plundering and destruction trends lead to a crisis for human survival."

Castro is in the city for a Caribbean energy summit on Wednesday.

He told the press at the airport that the summit is "a great success of the Venezuelan policy and President (Hugo) Chavez."

The head of state of Dominican Republic Leonel Fernandez and officials from Antigua and Barbuda, Barbados, Bahamas, Belize, Cuba, Dominica, Grenada, Jamaica, Saint Christopher and Nevis, Saint Lucia, Saint Vincent and the Grenadines, Surinam and Trinidad and Tobago are to attend the summit.
