  2. Green home - Wikipedia

    en.wikipedia.org/wiki/Green_home

    ENERGY STAR: In the United States, the ENERGY STAR program, administered by the Environmental Protection Agency (EPA), certifies homes that meet stringent energy efficiency standards. ENERGY STAR-certified homes are designed to use less energy for heating, cooling, and water heating, resulting in lower utility bills and reduced greenhouse gas ...

  3. Ground source heat pump - Wikipedia

    en.wikipedia.org/wiki/Ground_source_heat_pump

    Heat captured and stored in thermal banks in the summer can be retrieved efficiently in the winter. Heat storage efficiency increases with scale, so this advantage is most significant in commercial or district heating systems. Geosolar combisystems have been used to heat and cool a greenhouse using an aquifer for thermal storage.

  4. Zero-energy building - Wikipedia

    en.wikipedia.org/wiki/Zero-energy_building

    A Zero-Energy Building (ZEB), also known as a Net Zero-Energy (NZE) building, is a building with net zero energy consumption, meaning the total amount of energy used by the building on an annual basis is equal to the amount of renewable energy created on the site [1] [2] or in other definitions by renewable energy sources offsite, using technology such as heat pumps, high efficiency windows ...

  5. Efficient energy use - Wikipedia

    en.wikipedia.org/wiki/Efficient_energy_use

    Common energy efficiency label on appliances to indicate their energy efficiency in a clear manner. Efficient energy use, or energy efficiency, is the process of reducing the amount of energy required to provide products and services. There are many technologies and methods available that are more energy efficient than conventional systems.

  6. Greenhouse - Wikipedia

    en.wikipedia.org/wiki/Greenhouse

    Chinese solar greenhouses are designed to maximize solar energy, making them highly efficient in colder climates without the need for additional heating systems. Originating in 1978, these greenhouses feature three solid walls, often made of brick or clay, with a transparent south-facing side that captures solar heat during the day.

  7. Renewable heat - Wikipedia

    en.wikipedia.org/wiki/Renewable_heat

    Hot Springs located in Nevada. Geothermal energy is accessed by drilling water or steam wells in a process similar to drilling for oil. Geothermal energy is an enormous, underused heat and power resource that is clean (emits little or no greenhouse gases), reliable (average system availability of 95%), and homegrown (making populations less dependent on oil).
