A resident of Chișinău, Dinu Bubulici, has significantly reduced household energy dependence by combining solar generation, insulation, and heat pump systems in a single integrated setup.
His home, covering around 75 square meters, is equipped with an 8 kW photovoltaic system that generates approximately 8,000 kWh of electricity annually. According to him, improved thermal insulation plays a decisive role in overall efficiency.
In addition to solar panels, he uses heat pumps that transfer thermal energy depending on seasonal needs, providing heating during winter and cooling during summer by reversing operational flow.
Bubulici estimates that his household consumes roughly 8,000–9,000 kWh per year, with photovoltaic production covering around 90% of total electricity needs, while the remaining 10% is drawn from the grid.
Speaking on Radio Moldova, he noted that energy recovery systems remain relatively uncommon due to cost and complexity, though DIY approaches can partially mitigate expenses.
From his experience, he argues that the most effective strategy begins with thermal insulation of walls, ceilings, and floors, which reduces heat loss before investing in generation systems. He emphasizes that solar panels should be considered a complementary solution rather than the primary fix for inefficient buildings.

A diagnosis that shaped his passion
For some, childhood involves more than just games and fun; it also encompasses hard work, discipline, and a passion for learning. David Bordan, a fourth-grade student at the "Elena Alistar" Lyceum of Arts, plays the trumpet and the piano, practices dance, and demonstrates that talent and perseverance go hand in hand.

One in three children in Moldova lives in poverty
On International Children's Day, data on the situation of children in the Republic of Moldova highlights a troubling reality: one in three children lives in absolute poverty, and in rural areas, the phenomenon affects nearly half of all children.
