2. Ground source heat pump - Wikipedia

   en.wikipedia.org/wiki/Ground_source_heat_pump

   Annual greenhouse gas (GHG) savings from using a ground source heat pump instead of a high-efficiency furnace in a detached residence (assuming no specific supply of renewable energy) Country Electricity CO 2 Emissions Intensity GHG savings relative to natural gas heating oil electric heating; Canada: 223 ton/GWh [36] [37] [38] 2.7 ton/yr: 5.3 ...

3. Solar radiation modification - Wikipedia

   en.wikipedia.org/wiki/Solar_radiation_modification

   The first modeled results of and review article on SRM were published in 2000. [24] [25] In 2006, Nobel Laureate Paul Crutzen published an influential paper arguing that, given the lack of adequate greenhouse gas emissions reductions, research on the feasibility and environmental consequences of climate engineering should not be dismissed. [26]

4. Heating system - Wikipedia

   en.wikipedia.org/wiki/Heating_system

   Trends include the integration of smart home technology for better system control through allowing heat schedules, zones, and remote control. The use of renewable energy sources like geothermal heating, solar panels, and biomass. Current trends are toward heating pumps and using renewable energy/low carbon emission energy to power these heaters ...

5. Ground-coupled heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

   Potential benefits associated with shared ground heat exchange. A shared ground array comprises connected ground heat exchangers for use by more than one home. [1] They can deliver low-carbon heating where individual ground-coupled heat exchangers are not viable, such as in terraced housing with little outside space.

6. Solar thermal collector - Wikipedia

   en.wikipedia.org/wiki/Solar_thermal_collector

   The term "solar collector" commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non-water heating devices such as solar cookers or solar air heaters. [1] Solar thermal collectors are either non-concentrating or concentrating.

7. Thermosiphon - Wikipedia

   en.wikipedia.org/wiki/Thermosiphon

   Thermosyphon circulation in a simple solar water heater (not a working model; there is no water supply to replenish the tank when the tap is used). A thermosiphon (or thermosyphon) is a device that employs a method of passive heat exchange based on natural convection, which circulates a fluid without the necessity of a mechanical pump.
