Energy efficiency measures aim to minimize the amount of energy required to perform a specific task or achieve a desired outcome, without sacrificing performance or functionality.

Energy efficiency focuses on reducing energy consumption, not increasing energy production. It helps to conserve existing energy resources and reduce the need for additional energy production.

Green building refers to the practice of creating structures and using processes that are environmentally responsible and resource-efficient throughout a building's life cycle, from planning to design, construction, operation, maintenance, renovation, and demolition.

Wind energy is generated by harnessing the kinetic energy of moving air masses. Wind turbines convert the energy of the wind into electrical energy.

Solar energy is intermittent, meaning it is not consistently available due to factors such as weather conditions and time of day. This variability poses challenges for grid integration and reliable energy supply.

Anaerobic digesters are devices that break down organic matter, such as food waste or manure, in the absence of oxygen, producing biogas as a byproduct. Biogas can be used for cooking, heating, or generating electricity.

Geothermal energy is unique in that it is continuously available, regardless of weather conditions or time of day. This makes it a reliable source of energy that can be used to generate electricity or heat homes and businesses.

Improving insulation in walls and roof helps to reduce heat loss from a building, making it more energy-efficient. This can be achieved through various methods, such as adding insulation materials to walls, ceilings, and floors.

The photovoltaic effect refers to the process by which certain materials, such as semiconductors, generate an electrical current when exposed to light. This effect is utilized in solar photovoltaic (PV) systems to convert sunlight into electricity.

Tidal energy is generated by harnessing the energy of tides. Tidal turbines are placed in areas with strong tidal currents, and the movement of water causes the turbines to rotate, generating electricity.

One of the main challenges associated with energy storage technologies, such as batteries, is their relatively high cost. This can hinder their widespread adoption and integration into renewable energy systems.

Installing skylights in a building can help to reduce the need for artificial lighting during the day by allowing natural light to enter the interior spaces.

Geothermal energy involves the use of heat from the Earth's interior to generate electricity. This heat can be extracted from geothermal reservoirs through wells and used to power turbines that generate electricity.

Hydroelectric dams harness the energy of falling water to generate electricity. Water is stored in a reservoir behind a dam, and when released, it flows through turbines that generate electricity.

Energy conservation refers to the practice of reducing energy consumption through behavioral changes and lifestyle adjustments, such as turning off lights when leaving a room, unplugging unused appliances, and using public transportation instead of driving.
