The reliable and affordable supply of electricity and heating is an issue of major concern for Moldovan citizens, businesses and policy-makers. The viability and sustainability of the country’s energy sector rests on Moldova’s ability to diversify supply options and put in place the right tariff structures that would encourage investments in the energy sector. Currently, 98 percent of the energy resources consumed are imported, with over 80 percent of electricity and all natural gas coming from single sources.
To support the country’s energy sector development, the World Bank recently completed a study on electricity and heat tariffs in Moldova. The study shows the projected range of tariff increases, how much more different kinds of households would have to pay, how Ajutor Social program and the Heating Allowance could protect vulnerable people and how much those social payments would cost.
Let’s talk recycling: Not plastic and paper, but power…
These days, by far, the majority of electricity used in high-income countries comes from thermal power plants; these operate by heating water into steam that then spins a turbine. Thermal power plants, however, typically only use 33% to 48% of the total heat they produce. The rest just gets released into water or air. It’s a shame; if only there was a way to recycle all that ‘low-grade’ heat.
Today, 37% of the energy demand in OECD countries is for heating of buildings; only about 21% of energy demand is for electricity. We use much more energy for heating and cooling than we do for electricity. The low-grade heat that gets wasted by most power plants is still hot enough to be used for heating (and cooling) and water heating in buildings.
Why do we use so little of the heat we produce? That’s like buying a tub of fried chicken just to eat the skins!
