So is the investment justified?
Absolutely. In winter, however, when cloudy days are more frequent, the amount of hot water doesn’t satisfy our need, that is why we think of installing the second solar water heater. We only postpone it because of the new building construction being underway as all funding from our sponsors goes to financing the construction. The new building, by the way, will definitely have solar water heaters installed.
Are the students aware of this technology?
We have a course of Ecology at the school which includes various topics related to energy efficiency. It can be dangerous to take the students to the roof where the solar water heater is located, so we don’t have the opportunity to show them how in works in practice. However, I think most of them are aware that the school uses this kind of technology.
Renewable energy and energy efficiency are discussed widely today. How can an average citizen practically benefit from it? Is it affordable at all?
I think solar water heaters should become a common thing on our roofs, since the payback is very short. Moreover, it’s not just a matter of payback․
