Is photovoltaics viable from an environmental point of view?
One of the problems inherent with generating electricity today is the leakage of energy while it is transported between the large production units (nuclear stations, thermal stations, etc.) and the end user. It is said that one nuclear reactor needs to be kept in continuous operation in order to compensate for this level of energy leakage. It’s clear, therefore, that small, locally based units for generating electricity will help to limit these losses by providing sources of energy that are close to the point of consumption. This is borne out by the figures: if 1 Kwh of energy is consumed (by a private individual or company, etc.), 2.6 kWh of energy would need to be generated using currently available production resources. With photovoltaics, only 1.2 kWh of energy needs to be generated in order to effectively supply 1 kWh of energy to the end user.
Moreover, small photovoltaic installations based in private homes help to even out the demands placed on the electricity grid.
