Solar Water Heating Reduces CO2
Emissions
Currently Apricus solar
collectors are reducing CO2 emissions by more
than 5000 tones per year, with
collectors installed in the UK, USA, New Zealand, Germany,
France, Sweden, Italy, Hungary, Portugal, Jordan, Lebanon,
Australia, Canada, Mexico and many other locations. (One metric
tonne = 2200 pounds)
There has been a great deal of
information in the media over the past few years about
global warming and the role of CO2 emissions.
2003 saw extreme weather conditions and a heat-wave
throughout Europe, clear evidence of the realism of this
problem, commonly referred to as the "green house effect."
Burning fossil fuels such as coal for electricity
production, and gas for water heating both release large
amounts of CO2 into the atmosphere, thus contributing to
this environmentally harmful phenomenon.
By using renewable energy sources such a Solar Thermal,
Solar PV, Wind, Hydro and Geothermal, reliance on fossil
fuels can be minimised, thus directly reducing CO2
emissions. On average for every 1kWh of energy produced by a
coal power station, 1kg (2.2pound) of CO2 is produced.
Burning natural gas for electricity production or water
heating produces about 450grams of CO2 for every kWh of
energy produced.
In the average household, water heating accounts for around
30% of CO2 emissions. By installing a solar water heater,
which can provide between 50-70% of your hot water heating
energy needs, you can reduce your total CO2 emissions by
more than 20%.
Below are two calculators which can be used to estimate how
much you can reduce CO2
emissions by installing an Apricus solar water heater
together with either an electric or natural gas water
heater. Just enter your average annual insolation level and
number of evacuated tubes and click on calculate.
