    Re: No future for Wind Turbines

    lets not forget that with a 100 mw installed capacity gas power plant 100 % is available 24 hrs a day

    how much is available on average from a 1 mw wind turbine ? 25% if you're lucky

    No Pedders they are not available 100% 24 hrs a day.

    The very best new stations are 90%.

    As they get older their availability and reliability declines over time, old stations coming to the end of their life can be as low as 60%.

    We need a balanced mix of energy generation.

    The present shambles has added significant costs to new gas generation capacity as the risk premium has risen massively.

    The price of shale gas is also steadily rising. Spot prices (see link) are also not a reliable indicator of a 5 or 10 year deal.

    Yes - available 100% until Putin turns the taps off, the Iranians block the Straits of Hormuz and a scare story ends all shale gas exploitation.

    This seems most suitable for a Friday afternoon....

    The key thing here is not the short term trend on shale gas, but its price relationship to other forms of natural gas. So you will see on the undermentioned graph that whereas as you reveal, shale gas prices may be rising short term, the longer term gap between the cost of shale in the USA and natural gas in Europe is steadily widening. The USA are expected to be self sufficient in natural gas (and oil from shale) by about 2017, and this will ultimately have an effect on the world price. In addition China and Russia are also exploring huge reserves of as yet untapped shale gas. So personally I would differ with dire warnings of global energy shortages; new discoveries may well stabilize the market and possibly even reduce prices. This is assuming of course that the environmental lobby allow it to be extracted.

    Incidentally YCharts get most of their data from World Bank, so you can register on World Bank and build sophisticated graphs on all kinds of economic indicators straight from the horse's mouth as it where, and like your wind, all free of charge.
