    Interesting info on solar and wind energy.

    There have been many things said about the longevitey and footprint of solar cells and wind generators .

    This info from a trusted renewable energy information source puts 4 major criticisms to rest.

    Solar panels generate the energy required to build themselves in 1-2 years of operation, depending on type of panel and location, and their lifetime is about 20 years; large wind turbines in 3-12 months, depending on size of turbines and location, and their lifetime is 25-30 years.
    Renew Economy.

    These products are on the continuous improvement list as everyone knows and will only improve.

    eg, when solar cells were first being offered to everyone their efficiency was 4%.....Improvements in design now have solar cells at 20% efficiency.

    Good confirmation,

    we installed 20 solar panels and 6 kw system on our house in Oyster Cove ,Tassie.

    and now the heat pump hot water has failed after 15 years ,so we are installing an inverter to run the electric hot water tank
