4. APROVEITAMENTO DE FONTES ALTERNATIVAS PARA REDUÇÃO DO CONSUMO DE ENERGIA ELÉTRICA E REFLEXOS NOS SEUS CUSTOS / UTILIZATION OF ALTERNATIVE SOURCES FOR REDUCING POWER CONSUMPTION AND ITS CONSEQUENCES IN COSTS
Residential consumption accounts for around one third of total energy consumed in Brazil. The electric shower is the main component of this consumption, along with air conditioning. Hence, much research has been conducted in order to reduce the consumption of this sector and the use of alternative energy sources. Among these include mainly solar and geotherm
