Development in Offshore wind capacity
Offshore wind, currently around 3 000 MW, has mainly been concentrated in northern European countries, around the North Sea and the Baltic Sea. Europe’s leadership is primarily attributed to public policy and a thriving...

Spots of potential for wave energy harvest
Wave energy is captured directly from surface waves or from pressure fluctuations below the ocean surface. Wave power varies considerably in different parts of the world, making it more economically feasible to harness ...

Looking further offshore and in deeper waters
The high capital cost of offshore foundations bounds offshore wind energy to near shore locations. Most of the capacity has been installed in relatively shallow waters (under 20 m deep) no more than 20 km from the coast...

Public finance mechanisms across stages of technological development
In the early stages of development, public financial support is needed, both for R&D and then later to encourage deployment (see sections above for examples). Later, private finance can be mobilized for near-competitive...

Hydropower potential (theoretical possitibility for electricity generation)
xHydropower, generating electricity through turbines, represents a clean and renewable energy source, but not without problems. Dams and reservoirs disrupt the natural flow, and may increase siltation and evaporation, in...

Use of Renewable Fuels and Waste for Electricity Generation
In 2007, 15.8% of the supply of primary energy in Latin America and the Caribbean came from renewable fuels and waste (solid and liquid biomass, biogas, and industrial and urban waste). This is higher than the worldwide ...
