Pros of biomass is that it's renewable, made locally with minimal cost, promotes energy independence and converts waste into fuel. Cons of biomass is that large areas of land are needed, the geography of a country will limit the type of biomass used to create energy and some materials are not available year round.
advantages
Low cost of investment is less
It also displace above 2000 carbon dioxide emissions tons per year.
Avoids pollution
The Pelamis has a similar output to a modern wind turbine.
When complete, the project should meet the average electricity demand of more than 15,000 Portuguese households.
There is going to be only starting investment.
Minimum environmental impact.
Plenty of space plus high 'power-density'.
Survivability - 100 year wave
100% available technology
Hydraulic Power Take Off
Power smoothing
Tunable
Maximum site flexibility
Minimum work on-site
Off-site maintenance
dis advantages
· Disturbance or destruction of marine life (including changes in the distribution and types of marine life near the shore)
· Possible threat to navigation from collisions due to the low profile of the wave energy devices above the water, making them undetectable either by direct sighting or by radar. Also possible is the interference of mooring and anchorage lines with commercial and sport-fishing.
· Degradation of scenic ocean front views from wave energy devices located near or on the shore, and from onshore overhead electric transmission lines
wave energy as in tidal energy? because it is being used! in France and planned for the bay of fundy in canada. erosion does present a problem but theyre working on it. No, wave energy is different. Can be used where there are sufficient waves.

Country that uses the most wind power is Germany, then areas of Denmark also use alot of wind power. Next would be the U.S., and Spain follows right behind them. Other users include:
The United States and China are in a race for number one spot on this utterly useless form of power. They have both surpassed Germany as the leader. See the link below
All waves except electromagnetic waves and gravitational waves (predicted by General Relativity, but not yet detected).
Some examples are:
An increase in energy corresponds to an increase in frequency or a decrease in wavelength.
Refracted
LONGITUDINAL wave.
Air layers come closer at a particular time at a particular place is known to be compression. At the same place after some time the layers get separated. This is rarefaction.
For example, a sound wave.
