Wind Energy

 

A wind turbine is a rotary device that extracts energy from the wind. If the mechanical energy is used directly by machinery, such as for pumping water, cutting lumber or grinding stones, the machine is called a windmill. If the mechanical energy is instead converted to electricity, the machine is called a wind generator, wind turbine, wind power unit (WPU), wind energy converter (WEC), or aerogenerator.
   

Solar Water Heating

 

Solar water heating or solar hot water is water heated by the use of solar energy. Solar heating systems are generally composed of solar thermal collectors, a water storage tank or another point of usage, interconnecting pipes and a fluid system to move the heat from the collector to the tank. This thermodynamic approach is distinct from semiconductor photovoltaic (PV) cells that generate electricity from light
   

Photovoltaic Energy

 

Photovoltaics (PVs) are arrays of cells containing a solar photovoltaic material that converts solar radiation into direct current electricity.

This electricity can be used immediately or stored in a battery for later use or put into the grid. To create more power, PV cells can be linked together. Photovoltaic panels are usually made of many PV cells linked up. In the past, PV cells have been especially useful for creating electricity in remote areas where it is too costly to link up power cables with the main power supply.
   

Solid Earth Building

 

Because rammed earth structures utilize locally available materials, they typically have a low embodied energy rating and generate very little waste. Earth used for building is a widely-available resource and harvesting it for use in construction has minimal environmental impact.
   

Straw Bale Building

 

Straw-bale construction is a building method that uses bales of straw (commonly wheat, rice, rye and oats straw) as structural elements, building insulation, or both. This construction method is commonly used in natural building or "green" construction projects.

Advantages of Straw-bale construction over conventional building systems include the renewable nature of straw, cost, easy availability, and high insulation value.

   

Autonomous Homes

 

An autonomous building is a building designed to be operated independently from infrastructural support services such as the electric power grid, gas grid, municipal water systems, sewage treatment systems, storm drains, communication services, and in some cases, public roads.
   

Geothermal Heating

 

Geothermal energy is extracted from a reasonably constant earth core temperature of 54º to 56°F . Running a thermal loop to this constant core temperature by drilling wells vertically or horizontally allows for this heat transfer to a medium in pipes.
   

Heat Transfer Systems

 

Heat transfer is the transition of thermal energy from a hotter mass to a cooler mass. When an object is at a different temperature from its surroundings or another object, transfer of thermal energy, also known as heat flow, or heat exchange, occurs in such a way that the body and the surroundings reach thermal equilibrium; this means that they are at the same temperature. Heat transfer always occurs from a higher-temperature object to a cooler-temperature one.
   

Planting

 

Planting native plants can have many benefits, both aesthetical, ecological and economical. These include aiding farming operations, providing food and shelter for native birds, reducing erosion and much more.

Any garden, no matter how small or urban, can be made more attractive to wildlife. By planting native plants you'll provide shelter, shade, nesting places, reduce erosion and provide food in the form of leaves, nectar, berries and seeds. By meeting a bird's basic needs with food, water, shelter and a nesting place, they'll reward you with hours of entertainment and fewer insect pests!
