Potential for schemes is particularly high in Central and South America, although concerns remain over monitoring and proving how effective projects really are.

Probably the most popular use of cork now is flooring because it provides natural thermal insulation, thus helping to lower energy consumption, and it also has the natural ability to absorb sound and shock. It is a type of flooring that suits most allergy sufferers and is very durable despite its rubbery feel. Did you know there is actually a Cork Oak tree? Well, there is and it’s a pretty cool tree that is responsible for all those wine corks and cork flooring. Cork is harvested by peeling away the bark from the trunk and branches every 9-12 years and does not necessitate the felling of the tree. And, Cork Oak trees do not die when their bark is removed like most trees.

Like traditional bulbs, Halogen bulbs use a tungsten filament, but they use a halogen gas inside the bulb rather than argon or nitrogen, making the filament last longer.
Around half the size of traditional bulbs, they are most commonly used in fixed ceiling down-lighters.
It is expected that some lower-efficiency Halogen bulbs will be banned alongside incandescent bulbs under upcoming EU regulations, though the sale of higher efficiency models will still be permitted.

Usually implemented as a form of 'at source' taxation; i.e. those whom manufacturer or consume the most carbon pay and everybody else on the supply chain picks up the price increase. This is often encountered with a carbon credit scheme, by which carbon producers can 'offset' their taxable carbon emissions against less carbon intense production methods.
As always with such schemes, the devil is in the detail; in particular there has been problems in the past with carbon fraud.
Note: This equally applies to the energy production sector as basic manufacturing; say if coal is being used as a source of electrical power.
An electric vehicle (EV) is a vehicle powered by electricity, offering an alternative to traditional gasoline or diesel-powered cars. EVs are broadly categorized into Battery Electric Vehicles (BEVs), Plug-in Hybrid Electric Vehicles (PHEVs), Fuel Cell Electric Vehicles (FCEVs), and Hybrid Electric Vehicles (HEVs).

It can be a change in the average weather or a change in the distribution of weather events around an average (for example, greater or fewer extreme weather events). Climate change may be limited to a specific region, or may occur across the whole Earth.
In recent usage, especially in the context of environmental policy, climate change usually refers to changes in modern climate. It may be qualified as anthropogenic climate change, more generally known as global warming.

Search the Web for Horizontal Axis Wind TurbineA hot water recirculator is basically a pump that is put in at the furthest part of the hot water system in your house, this pump has a return line back to the hot water tank. A thermometer is used to control when the pump goes on, idea is that hotter water is kept in the pipe at all times, so reducing the time it takes for the hot water to 'appear' at the tap or shower head.
This is good for existing installations, but do make sure the pipes are well lagged. For new builds it is often easier to use a smaller bore pipe, so less water rests in the pipe so it draws from the hot water tank quicker.
The human food chain is the chain of food producers and consumers from the first producer to human consumption.
Search the Web for Human Food ChainHumidity is a term for the amount of water vapor in the air, and can refer to any one of several measurements of humidity. Formally, humid air is not "moist air" but a mixture of water vapor and other constituents of air, and humidity is defined in terms of the water content of this mixture, called the Absolute humidity. In everyday usage, it commonly refers to relative humidity, expressed as a percent in weather forecasts and on household humidistat's; it is so called because it measures the current absolute humidity relative to the maximum. Specific humidity is a ratio of the water vapor content of the mixture to the dry air content (on a mass basis). The water vapor content of the mixture can be measured either as mass per volume or as a partial pressure, depending on the usage.
In meteorology, humidity indicates the likelihood of precipitation, dew, or fog. High relative humidity reduces the effectiveness of sweating in cooling the body by reducing the rate of evaporation of moisture from the skin. This effect is calculated in a heat index table, used during summer weather.

Search the Web for HydrolysisHydronic flooring heating is where a network of water carrying pipes are embedded into the floor to transfer heat from a heat source (say solar hot water) to the floor - thereby providing a comfortable living environment. The only downside with such systems is that they depend upon the Sun to provide the warmth, this is often out of cycle with the demand for heat - i.e. you need to be warm in the evening and during cloudy days. Thermal mass can help phase shift the heating but you will often require additional back up heating as well.
This is often something which can only be done on a new build as you need to build the pipes into the structure of the floor. An option after build is to use a roof space heat recovery system to transfer the hot air from the roof into the living space by way of a filter and fan set up. The advantage with this is that such a system can also provide cooling air in Winter (as the roof space cools quicker than the living space below at night).
