Slow Food describes a movement created “to counteract fast food and fast life, the disappearance of local food traditions and people’s dwindling interest in the food they eat, where it comes from, how it tastes and how our food choices affect the rest of the world,” as defined on the movement’s website. More broadly, it places an emphasis on local and seasonal produce and an adherence to regional cultures. Its goals also include lobbying against the use of pesticides and genetic engineering of food.

Sea Level Pressure.

Smart Eco refers to the usage of computerization and ecologically focused system design to create locally grouped and controlled environments that have a reduced impact on the global environment. Examples of Smart Eco Design include: computer controlled irrigation systems that monitor weather conditions to minimize water usage; consumer appliances that are aware of power availability and adjust accordingly, and environmental controls that use passive design techniques to maintain a stable temperature.

A smart eco home is one which is designed to minimize its environmental impact through its lifetime. This includes the process of building and material selection.

Used widely as a major ingredient in cosmetics, skin care products, toothpaste, shampoos and other foaming products. Industrial uses of SLS include garage floor cleaners, engine degreasers and car wash soaps. SLS is also used in testing-labs as the standard skin irritant to compare the healing properties of other ingredients.

According to the American College of Toxicology, both SLS and SLES can cause malformation in children's eyes. Other research has indicated SLS may be damaging to the immune system and may cause potentially carcinogenic nitrates and dioxins to form in the bottles of shampoos and cleansers by reacting with commonly used ingredients found in many products. Also, large amounts of these nitrates may enter the blood system from just one shampooing. Studies have indicated that SLS easily penetrates through the skin and enters and maintains residual levels in the heart, the liver, the lungs and the brain.

Sodium perborate is a white odorless crystalline compound soluble in water. Its chemical formula is NaBO₃.

It is an important ingredient of many laundry detergent powders, laundry bleach additive products and automatic machine dishwash powders. Sodium perborate is also used as a tooth whitener in toothpastes, as an antiseptic, as a deodorant, and as a reactive agent (reagent) in industral processes.

An indicator of a soil's susceptibility to raindrop impact, runoff, and other erosive processes.

A solar chimney — often referred to as a thermal chimney — is a way of improving the natural ventilation of buildings by using convection of air heated by passive solar energy. A simple description of a solar chimney is that of a vertical shaft utilizing solar energy to enhance the natural stack ventilation through a building.

In its simplest form, the solar chimney consists of a black-painted chimney. During the day solar energy heats the chimney and the air within it, creating an updraft of air in the chimney. The suction created at the chimney's base can be used to ventilate and cool the building below.

A solar hot water system consists of a collector, heat transfer circuit and hot water storage system. These can either be combined into one system or into 3 separate components depending on your exact needs. There are many different commercial suppliers.

See Solar Water heating, how it works and the options available article for more information.

Solar Orientation refers to the solar alignment of a structure. Usually this used as one measure to determine the structures ability to harness solar energy. Most often used with respect to solar panels or buildings.

Electrical device consisting of a large array of connected solar cells.

Solar Panel Efficiency is a percentage measure of how Solar Energy from the Sun hitting a solar panel is ideally converted into useful electrical power. This is often given assuming perfect conditions; i.e. no shade, maximum sun and cool. In practice the actual rate of conversion can be somewhat different due to:

• Shading - even partial shading can have a dramatic effect on the energy produced.
• Heat - the hotter a solar panel becomes the less efficient it is at converting solar energy into electrical energy.
• Sun Strength - akin to shading, but if the Sun is behind clouds or low in the sky you will get dramatically less power.

A Solar Roof Tile is a roof tile engineered to function as a roof tile and also as a solar panel at the same time. This way the 'look' of the roof is not adversely impacted by a separate set of solar panels and existing roofing structures can be used to support the new tiles.

Solar Shades are movable semi-transparent coverings to windows that block out most of the Sun without obstructing the view. They have several benefits:

A device designed to receive solar radiation and convert it into thermal energy. Normally, a solar thermal collector includes a frame, glazing, and an absorber, together with the appropriate insulation. The heat collected by the solar thermal collector may be used immediately or stored for later use.

A Solar Water Pump is a water pump which is solely powered by Solar Panels, so as a result only runs during the day. This typically used for raising water into a holding tank to then allow water to distributed by gravity as needed, such as water from a well or river.

A method of separation used to purify vegetable oils.

Super Grid is a term referring to continent-wide energy grids that link far flung renewable energy sources with population centers.

Proposals for a European Super Grid, for example, would see solar farms in North Africa, wind farms in the North Sea and Russia, hydro electric facilities in Scandinavia, and geothermal power plants in Iceland all transmit energy to Europe.

Supporters of the proposals argue that spreading the energy grid across such a wide area and sourcing energy from a variety of different renewable sources would overcome concerns over reliability that can undermine efforts to increase renewable energy capacity.

Insulating a building to minimize the amount of heat that can escape from (or, in a hot climate, enter) a building.

One of the new generation of glazing technologies, superwindows are double or triple-glazed window sandwiches which contain a center sheet of coated mylar "low-emissivity' film and are filled with argon or krypton gas. This construction and the coatings on the film allows short-wave radiation (visible light) to pass through, but reflects long-wavelength radiation (infrared or heat) so heat can- not pass through. R-values of 4.5 or more are achieved.

A general term that describes environmentally-conscious design techniques in the field of architecture. Sustainable architecture is framed by the larger discussion of sustainability and the pressing economic and political issues of our world. In the broad context, sustainable architecture seeks to minimize the negative environmental impact of buildings by enhancing efficiency and moderation in the use of materials, energy, and development space. Most simply, the idea of sustainability, or ecological design, is to ensure that our actions and decisions today do not inhibit the opportunities of future generations.

This term can be used to describe an energy and ecologically conscious approach to the design of the built environment.

Clean Energy is energy which is produced without a negative impact on the environment. Essentially it is neutral in its production of pollution and its consumption of resources.

Sustainable energy refers to energy sources which are in themselves sustainable; e.g. they are not considered finite.

Typically these consist of: Hydro, solar, wind, biomass, geothermal and tidal.

Note: it is important when considering the technologies that utilize sustainable energy sources that the total lifetime cost is fully considered (e.g. from manufacturer, deployment, ongoing maintenance, to final disposal). Although the energy source many not be finite, the lifetime of operation of the technology to access them is finite and this should be considered. Basically there is no point in picking a sustainable energy source using a technology which requires constant maintenance or replacement, there is no net benefit to the environment or the consumer of the energy (higher costs and less reliable).

Sustainable tourism is where the operator and resort or service provider have made steps to ensure the act of tourism has minimal impact on the local environment and society.

This is often a bit of mixed blessing as sustainable tourism and 'eco tourism' has often been applied to businesses which are not really all that eco at the end of day. So therefore do make the effort to double check all claims and validate any recommendations.

The amount of a naturally self-reproducing community, such as trees or fish, that can be harvested without diminishing the ability of the community to sustain itself.

A swale is a low tract of land, especially one that is moist or marshy. The term can refer to a natural landscape feature or a human-created one. Artificial swales are often designed to manage water runoff, filter pollutants, and increase rainwater infiltration.

Synthetic crude oil made from coal of from oil shale.

Synthetic gas or synthetic oil. Fuel that is artificially made as contrasted to that which is found in nature. Synthetic gas made from coal is considered to be more economical and easier to produce than synthetic oil. When natural gas supplies in the earth are being depleted, it is expected that synthetic gas will be able to be used widely as a substitute fuel.

Synthetic gas make from coal.

A chemical absorbed by an organism that interacts with the organism and makes the organism toxic to pests.
