Depending on how
much wind capacity is in a region, a slight change in the rated capacity value for wind can mean a large change in future capacity requirements.
This much wind capacity will produce about as much electricity as 30 nuclear plants, and that will be a bit less than 5 % of the country's electricity.

On a bitterly cold day, with demand close to maximum, at the time of writing we have just gone a full 24 hours where the UK's
wind turbines have provided barely one twentieth of their notional
capacity, their output never once rising to as
much as even a tenth of their
capacity throughout the day and thus contributing nothing but uncertainty to the nation's supplies.

much lower than other energy sources.
Thus, consultants Ernst and Young note that, in 2005/2006, the UK's ROC system cost consumers 3.2 pence / kilowatt hour, whereas in 2006 the German Feed - In Tariff only cost consumers 2.6 / p / kWh — despite having a
much bigger
wind capacity in areas with generally
much less
wind than in the UK.

capacity of 5GW by 2020, is mapped out to take place off Jiangsu, Zhejiang, Guangdong and Fujian provinces.
State renewable portfolio standards require utilities to bring new renewable
capacity onto their grids no matter how
much it depresses markets, and renewable subsidies further erode electricity prices, especially in Midwestern states where subsidized
wind farms bid very low — even negative — prices for their power.
No matter how
much solar and
wind energy we produce, without grid storage we would need to maintain all of our peak
capacity.
Because
wind and solar power have a lower
capacity factor than nuclear or fossil fuels, their actual contribution will be
much lower.)
Wind capacity has also grown substantially over the past six years (and much more so in the years before that), but wind generation grew at a faster pace, partly because transmission constraints that previously prevented wind generators from operating at their maximum capability were gradually removed through a state - directed transmission expansion prog

much of that
capacity will actually be completed and by when remains to be seen.
The
much lower power - generating capabilities of renewables due to their intermittent output (the Sun has to shine and the
wind must blow) has meant that reliable backup
capacity — fossil fuels or nuclear — must remain on the grid.
In Esperance, WA for example, small, old, out - dated turbines have been replaced with bigger, newer ones; the

capacity can be relied on statistically to meet peak demand.
According to Flassbeck, the former Director of Macroeconomics and Development at the UNCTAD in Geneva and a former State Secretary of Finance, a recent period of extremely low solar and
wind power generation shows that Germany will never be able to rely on renewable energy, regardless of how
much new
capacity will be built.
Over a period of time, usually a year, the actual production is averaged out to what is called the «
capacity factor», which, is necessarily
much less than the the nameplate
capacity, since that is attained only in
wind speeds from about 30 to 55 mph.
Such a concept may make sense if you are trying to minimise the cost, averaged over a year, of providing backup
capacity, but this particular consumer is
much more concerned with avoiding power cuts in cold winters, so a Firm
wind capacity of zero should be assumed.
