This term doesn’t refer to all the spam filling your email box, though those messages do waste plenty of time. E-waste is actually the millions of tons of electronic products, computers, cell phones, and the like that enter the waste stream worldwide each year. As newer, better, cooler gadgets come on the market, the piles of e-waste grow ever higher. Aside from their contribution to landfills, many electronic devices contain hazardous materials, such as mercury; many also contain valuable, reusable materials that can be recycled. There are some simple ways to limit e-waste: Buy quality products that can be upgraded instead of replaced; donate old equipment (to a school for instance); and seek out recycling programs when you’re ready to dispose of an item. Also called electronic waste.Search the Web for E-Waste

Eco-anxiety is a chronic concern over environmental issues. This is not recognized as an official mental disease or dis-order. Rather it is a 'label' given to being overly concerned to the environment and a general feeling of helplessness in how to 'fix' it.
Being concerned about the environment is a good thing; in order to overcome any concerns you may have, we suggest
The end result should be a building which is good for the environment and cheap to live in.
Although, with the increased focus on being green in building, quite often regular architects either have direct 'eco' experience or have access to experts or resources to assist them - so do not select on the basis of an architect being eco alone.
Eco Architecture refers to designing buildings with a strong green and environmental element to them; e.g sustainable and minimizing the environmental impact of the final design.
Note: This does not necessarily mean existing buildings cannot be made more 'eco' rather this is focused on taking a new building and designing it from the ground up to be more eco friendly. When building it pays to consider the benefits of reusing an existing structure over knocking down and replacing it.
Being an informed purchaser. Knowing or having an understanding of what effect what you are doing, buying or using has on the environment.
This refers to a product or service having minimal impact on the environment in its provision. Unfortunately how 'minimal' is determined is somewhat open to interpretation and often depends upon context. This is also a phase that is often hijacked as part of a green washing campaign; so double check any claims.Search the Web for Eco Friendly
A very fuzzy 'Eco Marketing' term used to represent the fusion of many disciplines (including education, training, experience, materials availability, and eco inventions); on the premise that we need to tightly merge those disciplines to solely focus on 'improving the environment' in light of climate change. Often used to contrast against more loosely coupled business processes and distinct disciplines as being more 'green'; when often the real motivator is for the Eco Fusion advocate to 'control' more of the purchasing and business process for direct profit; in essence a form of ecofraud.Search the Web for Eco Fusion

Eco Lighting is lighting which is both energy efficient and has a light burden on the environment, i.e. they are easy to recycle and repair.
This is when a business deliberately markets itself as being 'eco' above and beyond the core functions or services of the business; when in actuality the business is not eco at all. This form of ecofraud is done to firstly pray on peoples tendency to assume anything eco is good; then secondly to utilise people's tendency not to question anything eco to sell on its core functions or services easily to eco minded people.
As we always recommend, make sure you have the real facts at hand (look on this site and use our search engine) and always shop around and do not over prefer the 'eco businesses' - quite a few businesses now are eco minded without feeling the need to promote it.Search the Web for Eco Marketing

An eco-architect is someone in the building design field (architecture) who either has specific training in designing eco-friendly houses, or equivalent accumulative knowledge.
This used to be quite a specialist field, as the methods and techniques employed were only understood by a minority of architects and designers; although now the ability to create eco-friendly houses can be enacted often by a regular architect, designer or drafts person using either specific software applications or following well understood principals of eco-friendly design (such as passive solar). Also the increased focus by local goverments through planning law on green building has made it almost universal that all architects or designers have had some experience with eco-friendly design.

Term introduced (“ecofeminisme”) by Francois d’Eaubonne in the 1974 text Le Feminisme ou la Mort. Dissatisfied with ecological analyses that leave patriarchy out of account, ecofeminists out parallels between how men in the West mistreat women and how they mistreat the Earth: in both cases a relationship of power, control, a will to dominate, and a pervasive fear of of the fact of interdependency. A twist on this is the patriarchal habit of objectifying women while feminizing the environment; women are then seen as less mature or human because "closer to nature."Search the Web for Ecofeminism
This term is associated with a business/group or individual who engages in or who presents themselves as being a subscriber to sound science based eco and environmental principals; when in fact they are either:
a) solely being 'Eco' for personal or monetary gain, with little real regard for any eco or environmental principals or,
b) totally misrepresenting, misapplying or distorting sound scientific based eco and environmental principals to add weight to an argument or issue.
The first case is usually very deliberate in intent; whereas with the second case, a person or group can be 'duped' into believing and then promoting an 'eco fact' - when in fact it may have little empirical or scientific basis when the bigger picture (either in time or space) is considered.
This in itself is nothing new, misquoted and misunderstood information abounds in everyday life; but what is concerning is the degree of lack of question and real knowledge share that often occurs when people are confronted with an 'Eco fact'; please demand to be informed. Remember: a decision based on ecofraud info could well be doing longer term harm to our Environment.Search the Web for Ecofraud
Environmentally friendly (eco-friendly and nature friendly) are synonyms used to refer to goods and services considered to inflict minimal harm on the environment.
To make consumers aware, environmentally friendly goods and services are often marked with eco-labels. But because there is no single international standard for this concept, the International Organization for Standardization considers such labels too vague to be meaningful.
An Ecohome is a house which has been designed from the ground up to be environmentally friendly whilst at the same time energy efficient.
Usually this requires a custom build (which can be expensive); although with some careful thinking it is possible to make an existing property more eco friendly whilst preserving the embedded energy incurred when it was built. Too often existing properties are demolished that could have been made 'good' with a bit thought.
A seal of approval (or certification) of a product, process or service

The amount of energy service or useful energy delivered per unit of energy input. Often used in reference to lighting systems, where the visible light output of a luminary is relative to power input; expressed in lumens per Watt; the higher the efficacy value, the higher the energy efficiency.
A warming of the surface waters of the eastem equatorial Pacific that occurs at irregular intervals of 2-7 years, usually lasting 1-2 years. Along the west coast of South America, southerly winds promote the upwelling of cold, nutrient-rich water that sustains large fish populations, that sustain abundant sea birds, whose droppings support the fertilizer industry Near the end of each calendar year; a warm current of nutrient-poor tropical water replaces the cold, nutrient-rich surface water Because this condition often occurs around Christmas, it was named El Niho (Spanish for boy child, referring to the Christ child). In most years the warming lasts only a few weeks or a month, after which the weather patterns return to normal and fishing improves. However; when El Nino conditions last for many months, more extensive ocean warming occurs and economic results can be disastrous. El Nino has been linked to wetter; colder winters in the United States; drier; hotter summers in South America and Europe; and drought in Africa.Search the Web for El Nino

This is a concept often used by policymakers in reference to the problem that emissions abatement achieved in one location may be offset by increased emissions in unregulated locations. Such leakage can arise, for example, in the short term as emissions abaters reduce energy demand or timber supply, influencing world prices for these commodities and increasing the quantity emitted elsewhere; and it can arise in the longer term, for example, as industries relocate to avoid controls.Search the Web for Emissions Leakage
This is an economic incentive-based alternative to command-and-control regulation. In an emissions trading program, sources of a particular pollutant (most often an air pollutant) are given permits to release a specified number of tons of the pollutant. The government issues only a limited number of permits consistent with the desired level of emissions. The owners of the permits may keep them and release the pollutants, or reduce their emissions and sell the permits. The fact that the permits have value as an item to be sold or traded gives the owner an incentive to reduce their emissions.Search the Web for Emissions Trading
Emissions trading or cap and trade is usually a government-mandated, market-based approach to controlling pollution by providing economic incentives for achieving reductions in the emissions of pollutants.

Ethical investment refers to investment which takes into account all the effects of the investment, both positive and negative to people, the environment and quality of life in general. Such investment aim to therefore be 'ethical' in how they invest, as opposed to other forms of investment by implication which are not ethical.
Note: An ethical investment does not provide a greater power to grow wealth, rather it is a choice taken by the investor in what they are willing to investment in, and hence it is a marketing exercise - the risk and benefits mix is not considered as to whether an investment is 'ethical'.

An evacuated tube is most often encountered in solar hot water heating systems. This is where a glass tube is used, with a good heat conductor placed in the middle of it. All the air is removed from the tube, so that when the Sun light hits the heat conductor no heat is then lost out to the tube itself. This way the maximum amount of heat is caught and sent up the heat conductor to then heat the water passing over at the top of the tube.
The other advantage with this approach is that the tube will be placed to be always inline with the Sun as it move through the sky, i.e. no matter where the Sun is the central conductor will present the same surface area to heat.
Often these heating systems are so efficient, that over temperature valves and safety guards need to be put into the installed system.
