The significance of solar hot water installations in meeting CO2 emissions reduction
Water heating accounts for quarter of the energy used in an average home in Australia and is responsible for 24% of the total greenhouse gas emissions from home energy use. In Poland, water heating accounts for 14% of the total energy use at home. Therefore solar hot water installations have the potential of decreasing the CO2 emissions significantly. An important benefit of solar water heaters is reduction in fossil fuel consumption which assists in reducing CO2 production. But in order to encourage premises installing the solar hot waters, appropriate law has to be created. Historical data in Australia shows that it has not always been easy to form appropriate schemes that would be sustainable. There is no aggregate target in legislation as for now. And so a detailed look at the policies has to be taken.
To prepare a detailed analysis of solar hot waters the embodied energy (energy to make a product) will be considered. An LCA of different solar hot water heaters will reveal how much energy it takes to produce a collector as well as how much CO2 is emitted at this stage.
Other goals of the study are the analysis of insolation, system efficiency measurements, calculation of system sizing and energy savings.
Further research will include the emissions that will be cut by replacing electric heaters by solar hot waters as well as calculation of number of years needed to pay back the manufacture emissions amount.
