A new report from the European Environment Agency has concluded that wind power's potential in 2020 is as much as three times greater than Europe's expected electricity demand, rising to a factor of up to seven times demand by 2030.
"The EEA clearly recognizes that wind power will be key to Europe's energy future. Now that oil prices are again on the rise, the EEA report sends a reminder to Europe's policy makers that wind power is a clean and proven energy technology and Europe is the world leader," Christian Kjaer, EWEA CEO.
This study confirms that wind energy can play a major role in achieving the European renewable energy targets and that the extent of wind energy resources in Europe is very considerable. The report, ‘Europe's onshore and offshore wind energy potential,' highlights that the wind energy potential is huge, equivalent to almost 20 times energy demand in 2020. Onshore wind energy potential is concentrated in agricultural and industrial areas of north-western Europe. Likewise, the largest offshore potential can be found in low depth areas in the North Sea, the Baltic Seas and the Atlantic Ocean, with some local opportunities in areas of the Mediterranean and Black Seas.
The deep offshore potential is even larger but costs mean that it is unlikely to contribute in any significant way to the energy mix within the time horizon of the study. Using only 4 % of the offshore area within 10 km from the coast and accounting for the restrictions imposed by shipping lane, gas and oil platforms, military areas, reduces the potential by more than 90 % to 2800 TWh in 2020 and 3500 TWh in 2030.
When production costs are compared to baseline average electricity generation costs, the onshore potential for wind decreases to 9600 TWh in 2020, whereas offshore wind potential decreases to 2600 TWh. Despite being a small proportion of the total technical potential, the economically competitive wind energy potential still amounts to more than three times projected demand in 2020.
However, high penetration levels of wind power will require major changes to the grid system at higher penetration levels, with additional extensions or upgrades both for the transmission and the distribution grid possibly required to avoid congestion.
The conclusions were welcomed by the European Wind Energy Association (EWEA), with CEO Christian Kjaer observing: “The EEA clearly recognizes that wind power will be key to Europe's energy future. Now that oil prices are again on the rise, the EEA report sends a reminder to Europe's policy makers that wind power is a clean and proven energy technology and Europe is the world leader."

Distribution: it's important to work also on systems that are embedded in local networks, including at the level of individual dwellings. Among relatively neglected options, cogeneration with gas central heating has the obvious advantage in cold regions of providing most power when it's most needed. Also, there's no special building or installation work. This idea seems to be stalled, possibly for lack of a suitable gas engine and for reasons linked to the structure of the industry.
"If wind is a small part of generation, its intermittency brings few operating problems ... When it reaches approximately 10 to 15 percent of power production, the added costs of units that must run to ensure reliability can become substantial. ..... As advocates claim, wind produces nearly 20 percent of Denmark's total generation. Fortunately, that nation is a small part of a much larger, centrally dispatched Scandinavian system largely based on hydroelectric and nuclear facilities. Denmark's wind units produce less than 3 percent of the region's power. Load and generation characteristics force the nation to export nearly half of its wind power, often at zero prices, and to pay premia to fill in any shortfalls. According to NUS Consulting Group, in 2007 the average cost of energy production in the U.S. was approximately 9.5 cents per kWh, and in largely nuclear France, it was just more than 8 cents. In Denmark, it was 23 cents."
Above all Renewable Energy at the most local level is the major way forward,as transmission losses from coal input to socket outlet are 80%?
Gas perhaps 70%? All domestic buildings should be self sufficient and small commercial also. Local systems are 95% efficient!
Wind plus solar plus bio-fuel should be mandatory at local build level.
Imagine the local employment and effect on GDP!
Who needs NATO and world banksters exporting (and importing) terrorism, pollution and poverty if legitimate governments can issue their own usury-free currency?
