What are the 3 main strategies for sustainable energy management?
Education, energy efficiency, and conservation.
Why is education important for energy management?
Teaches people smarter energy use and how to reduce enegry consumption
Why is energy efficiency important for energy management?
Using technology or methods that reduce energy to achieve the same result (LED bulbs and energy efficient appliances)
What is conservation in energy management?
Using less energy by reducing waste and consuming only what is necessary (e.g., using public transport, turning off unused devices)
Why is sustainable energy management important?
It helps to reduce environmental impacts, save money, and preserve resources for future generations.
