The world's leader in wind "penetration" -- with wind turbines producing energy equal to around 20% of the country's electricity use -- Denmark also leads in running up against the practical limits of erecting giant wind turbines to supply the grid. As
Kent Hawkins has calculated, with the help of
Vic Mason, who works in Denmark and has access to Danish-language reports, the actual penetration limit for wind, which is intermittent, highly variable, and nondispatchable -- all the very opposite of the grid's needs -- appears to be 6%, the rest being dumped into larger markets in Germany and the rest of Scandinavia.
In any case, Denmark has not added new wind energy capacity since 2003:
Year: | 2001 | 2002 | 2003 | 2004 | 2005 | 2006 | 2007 |
Installed wind capacity (MW): | 2,489 | 2,892 | 3,117 | 3,125 | 3,129 | 3,136 | 3,125 |
