Nij Bosma Zathe is an experimental Dutch farm with 200 dairy cows. The manure these cows produce is used to make biogas. The gas is turned into electricity in a generator which feeds it into the national grid. The heat this releases goes directly to houses in the new estate in Techum.
The heat arrives, through a grate in the wall, in Carla Koelstra's home five kilometres away. "Just a push of the button and the house is warm," she says. Her children are surprised it doesn't smell: "They must use a lot of perfume on it."
As a result of the economic recession, not all the houses planned for this neighbourhood have been finished. Less than a hundred are now heated by means of biogas.
At a ceremony in October, a new array of solar panels was dedicated at St. Barnabas Episcopal Church, given by theI attended St James's, Piccadilly when I lived in London. In September, Reuters did a short video about churches and carbon footprints and it includes a look at St James's and its photovoltaic panels. Have a look here.
White Flowers Foundation and the children of church member
Ann Flowers in honor of Ann's 80th birthday. Bishop Thomas
Ely was present to celebrate with the family, the congregation,
and church's rector, the Rev. Beth Hilgartner. The Bishop
spoke of every solar panel being "a sign of our commitment to
a sustainable future for this planet..." The photovoltaic panels
are connected to the power grid, and on sunny days, the electric
meter now runs backwards, giving the church credit for the
power used at night and on cloudy days.
