How much electricity could Tanzania save simply by using more energy-efficient appliances? According to a recent study, the answer is a lot.

Energy efficiency was the focus of discussions during the Breakfast Debate held in May 2026 in Dodoma, where stakeholders explored practical ways to reduce energy waste and promote sustainable energy use across the country.

Findings from the 2026 Minimum Energy Performance Standards (MEPS) Impact Assessment Study reveal that Tanzania could save about 5.1 terawatt hours (TWh) of electricity by 2035 and prevent nearly 2.5 million tonnes of carbon dioxide (CO₂) emissions. These savings could be achieved through the introduction and enforcement of energy efficiency standards and energy labels for commonly used household and commercial appliances.

The study examined six key appliance categories: refrigerators, lamps, televisions, electric motors, fans, and air conditioners. Together, these appliances account for a significant share of electricity consumption in homes and businesses.

Among them, refrigerators are expected to deliver the biggest energy savings, contributing about 1.8 TWh, followed by lamps with 1.5 TWh. Televisions, electric motors, fans, and air conditioners will also play an important role in reducing electricity demand nationwide.

The benefits go beyond saving electricity. Experts estimate that the total energy savings could support the operation of nearly 200,000 electric vehicles and reduce the need for about 55 million litres of petrol every year. This would not only lower energy costs but also help protect the environment.

Consumers also stand to save money on their monthly electricity bills. For example, a standard 210 litre refrigerator that does not meet efficiency standards uses about 330 kWh of electricity each year, costing approximately TSh 117,810. A refrigerator that meets the minimum efficiency standards would use less electricity and save around TSh 29,631 annually. Choosing a highly efficient five-star refrigerator could save nearly TSh 73,899 every year.

The same applies to other appliances. Energy-efficient lamps use less electricity while providing the same level of lighting. A five-star air conditioner, for example, can save more than 1,500 kWh of electricity annually, translating into savings of about TSh 538,356 each year.

For consumers, the message is simple: check the energy label before making a purchase. Appliances with higher star ratings use less electricity and can lead to substantial savings over their lifetime, even if they cost slightly more upfront.

As Tanzania continues to expand access to electricity and support economic growth, improving energy efficiency is becoming one of the smartest and most affordable ways to meet rising energy demand. The adoption of MEPS and Energy Labelling is also in line with the country's efforts to address climate change and reduce pressure on the national power system.

Stakeholders emphasise that public awareness, effective market monitoring, and strong enforcement of energy efficiency regulations will be key to ensuring that Tanzanians fully benefit from these technologies and the savings they can deliver.
