How does use of solar water heater help the environment?
A 100 litre system, the average size of a household of 3 – 4 people, can prevent emissions of 0.4 to 1.0 tonnes of carbon dioxide per year. The reduction in emissions of carbon dioxide (one of the major green house gases) can positively help in slowing down the pace of global warming. Moreover, using a commercially and technically viable technology using sun to heat up water can help ease burden on our overloaded electricity supply system, and also free other limited energy sources like fossil fuels which can be used elsewhere.
