Wind turbine makes a home energy self sufficient |
This is very important news . It means that this house is
generating all its electricity and energy needs , since electricity is
only about 20% of our energy needs. Note he runs his heating and
cooking requirements from the turbine as well!
And what is $40,000 to make a house energy self sufficient ?.
its the cost of a car and can make it energy surplus for ever! Its
time the govt made it a law that all new homes must be renewable
energy surplus and we told the OPEC countries what they can do with
their oil , instead of the Yanks paying them $600m a day or $200b a
year . $20b of that saving could be used to build a six lane
underground rail network each year , freeing the overland for human
use and taking our planet back from the metallic monsters.

How to make home a powerhouse
Robin McKie, science editor
Sunday October 23, 2005
The Observer
Monthly bills for hot water, central heating and lighting no longer
trouble Geoff Welton and his wife Judith since they installed a wind
generator on their smallholding.
In fact, they have been making money. 'We have generated more than
7,000 kilowatt hours of power, but used only 2,500 hours - even though
we have electric central heating and electric cookers,' says Mr
Welton. 'We have sold the rest to the power company.'
The Weltons' generator cost £22,000, with the government providing a
£5,000 grant. 'We will have paid it all off in eight years,' said Mr
Welton. 'Of course, it's windy up here. That helps.'
And what the Weltons, of Togmorden, Lancashire, have done today,
thousands in cities and countryside may be doing themselves in the
next few years, according to a new report, 'Seeing the Light', to be
published tomorrow by the Sustainable Consumption Roundtable. Its
authors envisage a future in which we all generate electricity at
home: wind turbines on roofs, solar panels in gardens and heat pumps
in basements.
Homeowners could meet a quarter of our Kyoto commitments this way by
cutting their dependency on coal and gas-generated electricity.
'The benefits go beyond saving money and cutting carbon emissions,
however,' added Alan Knight, the group's chairman. 'People become
personally involved in energy saving and climate change when it
becomes part of their home life. They start looking elsewhere to
help.'
But the report warns that the government must take urgent action to
help the microgeneration cause. The grant scheme that helped Mr Welton
buy his generator in February is set to end next year. 'We need more
of these schemes,' added Knight.
'Wind turbines and solar panels are still too costly. If the
government placed mass orders for them, and placed them in town halls
and schools, prices would plunge. Then we could all afford them. To
install a generator or solar panel today, you need specialist help.
You should be able to buy one at B&Q and stick it in yourself.'
It is a point backed by the Energy Saving Trust, which is launching
its Energy Saving Week tomorrow. By adopting a range of simple
measures, people can cut hundreds of pounds from their electricity
bills, it argues. Turning down your central heating thermostat by 1C
would cut 10 per cent from your heating bill, while the latest
high-efficiency condensing boiler could cut a third from your power
bill.
Such moves not only save money, they cut carbon emissions because we
use less electricity or gas. In Britain, each person is responsible
for pumping between 2.4 and 2.9 kilos of carbon into the atmosphere
every year. Intriguingly, figures released last week by the Department
of Environment, Food and Rural Affairs show startling variations in
this carbon footprint.
In eastern England and Scotland, the figure is 2.9. In Northern
Ireland, it is 2.4, while in London it is 2.6. 'It is not exactly
clear why Londoners are lower emitters than the Scots,' admitted a
Defra spokesman. 'It cannot merely be weather, for it's as bad in
Northern Ireland as it is Scotland. Bigger houses, which need more
heat, may have something to do with it. It's a real effect,
nevertheless.'
In other words, householders in some areas are going to have to work
much harder to keep their carbon count down than those in other areas.
Other options they might consider include the use of grey-water
recycling plants that use dishwasher waste as toilet flush water.
The options are endless, says Mr Welton. He has already bought a
second wind generator for his stables and is considering the purchase
of a solar power panel to heat his water. 'We are not greenies. I just
think we have to take individual responsibility for the future.'

What this house does is probably using its wind power when there is
wind, selling its surplus power to the grid, and buying power from the
grid when there is no wind but a need for electricity. It's green
power, but obviously, there is a limit to the amount of homes that the
current grid can host in this manner.
Taking the house off-grid is the next step. It's not impossible, but
will not come as an investment with 8-year payback.
Also, note that electricity is 20% of final energy use, 40% of primary
energy use, but also that domestic electricity use is about 15-20% of
total electricity use. We use 6 times more electricity in industry, in
the office, in the products we buy, than we use at home.
