Public interest in understanding their own electricity consumption has grown significantly in Brazil. A survey by Bulbe Energia, based on data from Google Brazil, shows that searches for the term "calculate energy consumption" increased by 260% between December 2024 and November 2025.
During the same period, searches for "discount on electricity bill" grew by 110%, totaling more than 261 queries. This trend coincides with the increase in tariffs throughout 2025, changes in tariff flags, and uncertainties regarding projected energy costs for 2026.
Another topic that gained relevance in searches, especially in the final stretch of last year, was... Social Electricity TariffThe inquiries indicate a significant volume of questions about the program, which serves families registered in the Unified Registry for Social Programs (CadÚnico), beneficiaries of the Bolsa Família program, retirees, and people with disabilities, offering progressive discounts on bills according to consumption levels.
Given this scenario, consumers have also started looking for alternatives to reduce the impact of their electricity bills, whether through social programs or companies that promise direct savings on the monthly cost.
Expressions such as "how to get a discount on your electricity bill" and "companies that offer discounts on electricity bills" reinforce this behavior and point to an increased interest in alternative supply models, such as solar energy subscriptions or the installation of photovoltaic systems themselves.
According to Energy BulbThis movement reveals a shift in consumer profile, with consumers now evaluating options outside the traditional distributor model and comparing solutions available on the market. The study highlights that by understanding kWh consumption, consumers can analyze whether it makes sense to join social programs or compare proposals from companies in the electricity sector.
Furthermore, practical guides explaining how to calculate consumption – based on equipment power and usage time – have also gained traction in searches, reinforcing the demand for greater control and predictability of energy expenses.

An answer
Dear Sir/Madam, among all the possibilities for reducing electricity costs, and for those who have the financial means, self-generation through a solar system stands out, offering very good financial returns. Another alternative, still largely neglected, is solar water heaters instead of energy-consuming devices, such as the infamous electric showers, which, in a tropical country like Brazil, have an excellent return on investment, both in terms of IRR and payback period.
