Energy efficiency refers to using less energy to accomplish the same tasks or achieve the same level of comfort. It involves optimizing technology and practices to minimize wasted energy.
Renewable energy sources: Renewable energy sources are natural resources that can be replenished over time without depleting them permanently. Examples include solar power, wind power, hydropower, and geothermal energy.
Insulation: Insulation is a material used in buildings or appliances that reduces heat transfer between different areas or surfaces. It helps maintain desired temperatures while minimizing the need for excessive heating or cooling.
Smart grid: A smart grid is an advanced electrical grid system that uses digital technology to optimize the generation, distribution, and consumption of electricity. It enables better monitoring and control of energy usage.
