Top 10 Green Heating and Cooling Technologies
1. Geothermal
Geothermal energy is heat derived within the sub-surface of the earth. Water and/or steam carry the geothermal energy to the Earth’s surface. Depending on its characteristics, geothermal energy can be used for heating and cooling purposes or be harnessed to generate clean electricity.
2. Solar (Passive)
Passive solar design takes advantage of a building’s site, climate, and materials to minimize energy use. A well-designed passive solar home first reduces heating and cooling loads through energy-efficiency strategies and then meets those reduced loads in whole or part with solar energy. Because of the small heating loads of modern homes it is very important to avoid oversizing south-facing glass and ensure that south-facing glass is properly shaded to prevent overheating and increased cooling loads in the spring and fall.
3. Solar (Active)
Active solar heating systems use solar energy to heat a fluid — either liquid or air — and then transfer the solar heat directly to the interior space or to a storage system for later use. If the solar system cannot provide adequate space heating, an auxiliary or back-up system provides the additional heat.
4. Biomass
People have used biomass energy—energy from living things—since the earliest “cave men” first made wood fires for cooking or keeping warm. Today, biomass is used to fuel electric generators and other machinery.
5. Hydronic Heating
The hydronic system simply heats water and moves it through sealed pipes to radiators throughout the home. The sealed system can also be used to heat towel rails, floor slabs, even swimming pools, anywhere where it is needed. Hydronic Heatingheats water at its source via super energy efficient Gas Boilers.
6. Absorption
Energy absorption is the basis of greenery color, and pigments are the basis of energy absorption. The color we perceive arises from unwanted energy that is reflected or transmitted. … Such a biological system, relying on absorption of electromagnetic energy for its survival, must have a means of absorbing energy.
7. Biodiesel
Biodiesel is a liquid fuel produced from renewable sources, such as new and used vegetable oils and animal fats and is a cleaner-burning replacement for petroleum-based diesel fuel. Biodiesel is nontoxic and biodegradable and is produced by combining alcohol with vegetable oil, animal fat, or recycled cooking grease.
8. Ice-powered Air Conditioners
During hot days, homes and buildings turn up the air conditioning, which uses a tremendous amount of power. Ice-powered air conditioners make ice at night and use it to cool the existing air conditioning units’ refrigerant during the day, which decreases the amount of electricity a building uses.
9. Green Coal
Green coal technology, also known as clean coal technology is a new trend in the use of coal by coal power stations that advocates for the improvement in the efficiency of coal burning (so that no carbon or carbon monoxide particles are produced in the exhaust), and the capture of the gases SO2 and NO2, which are common by-products that are harmful to the environment surrounding the power stations (which is the whole world).
10. Wind Power
\Wind energy (or wind power) refers to the process of creating electricity using the wind, or air flows that occur naturally in the earth’s atmosphere. Modern wind turbines are used to capture kinetic energy from the wind and generate electricity.
