Renewable energy systems aim to utilize sustainable, inexhaustible resources like solar and wind to replace finite fossil fuels.
Nuclear energy is not renewable because it relies on finite uranium resources, whereas the others depend on naturally replenished sources.
The Law of Conservation of Energy states that energy cannot be created or destroyed but only transformed, emphasizing efficient use and reduced wastage.
Energy-efficient systems lower energy consumption, leading to reduced greenhouse gas emissions and environmental benefits.
ECRE commonly stands for "Energy Conservation and Renewable Efficiency," which focuses on sustainable energy solutions and efficiency improvements.
