Facts About Wave Energy• 2 TW of power from deep water11

• 2 TW is the approximate power generated between the surfaces of Jupiter and its moon due to Jupiter's magnetic field11

• 3.34 terawatts is the average energy consumption in the United States (2005)11

• In 2005, global electricity consumption averaged 2 TW11

Problems

• Not cost effective10

• Wave sizes12

Advantages of Wave Energy

• We only need to harvest 2 one-thousands of the oceans energy9

• Waves are consistant and predictable8

• Waves tend to be stronger in the winter5

• The majority of the worlds population lives within reachable distance of the coast3

How Can We Support Wave Energy?

• Maryland Clean Energy Center

• Chesapeake Bay and its major rivers and tributaries6

• US Naval Academy
