TIDAL TURBINE
WAVE ENERGY
Electricity production represents nearly half of CO2 emissions in the atmosphere. It’s essential to explore all the existing technology options to reconcile our growing need for electrical energy with the fight against climate change.
The benefits of tidal energy
· Tidal power offers an inexhaustible supply of energy, free of greenhouse gas emissions once installed. It also has the advantage of being totally predictable, as tidal currents result from perfectly known astronomical phenomena.
· If all suitable tidal sites in the world were exploited for tidal power, it’s estimated that 100 TWh of electricity could be produced each year.
· Wave power offers one of the largest potential resources among available marine energy sources
The wave power could produce between 200 and 300 GW, using the most promising sites worldwide. If more areas were exploited, the number could be even higher.
Renewables are expected to produce 30% of Europe’s electricity by 2020 according to EU targets. At the world’s scale, in 2050, 77% of the Worlds energy supply could be covered by the renewable energies, according to one of the GIEC’s special reports. In that context, wave energy has a huge potential. And since the waves producing the highest levels of energy are found close to densely populated regions, including Western Europe, Canada and the USA, wave energy is a key area for development.
