Energy efficiency projects aim to reduce the amount of energy used to do something

Not as well known as renewable energy, it delivers emission reductions from a wide range of projects

The emission reductions achieved by the energy efficiency action are credited and can be used as an offset

 

When you buy an energy efficiency carbon offset, you are buying these reduced emissions

 

More Than Changing Light Bulbs

Many think of energy efficiency as being about “changing light bulbs”

Some projects do focus on using more efficient technologies for lighting, heating or cooling systems, or for a factory’s process equipment.  Others install energy saving appliances/ products in homes or businesses.

Cogeneration (combined heat and power) and Combined Cycle Gas Turbine (CCGT) projects are also energy efficiency projects

Energy efficiency also offers so much more – cookstoves, safe water, Autoclaved Aerated Concrete blocks among others

Improving Living Conditions

Safe Water

Safe Water means
access to an improved water source on site, available when needed and free from contamination

2,200 million people do not have access to safe water

at least 2 billion people’s source of drinking water is contaminated with faeces

 

Basic services means not having to walk more than 15 minutes for clean water

785 million cannot even access this

144 million rely on water from untreated surface water like lakes, ponds, rivers and streams

(World Health Organisation)

Cookstoves

Around 2,600 million people cook using open fires or simple inefficient stoves

They use firewood, charcoal, animal dung, crop wastes, kerosene and coal

Improving stove efficiency reduces the fuel used – better burning also reduces smoke indoors

Nearly 4 million people will die prematurely this year from household air pollution

Almost 50% of pneumonia deaths in kids under 5 years are caused by breathing soot

Energy Efficiency Technologies

Cookstoves

Projects involve manufacturing and/or disseminating 1000’s of highly efficient cookstoves

Cookstoves can come in different sizes to help families and small to medium sized businesses

The cookstove may include a ceramic liner to increase combustion efficiency and retain heat

Some are 50% more fuel efficient than traditional methods

Replaces coal and other solid fuels (firewood, charcoal, dung, straw) for cooking and heating

Improved cookstoves improve fuel efficiency
Improved cookstoves burn fuel more efficiently, producing less smoke

Cookstoves reduce emissions, help curb deforestation and improve indoor air quality

They provide relief from high fuel costs, decrease the time and energy spent collecting fuel, cook faster and improve health by creating less indoor pollution

They help protect family members from burns and accidents common to open-air fires

Projects can contribute to gender equality and empowerment of women.  They provide ownership of a new asset, the stove

Safe Water (Borehole Rehabilitation)

Many rural areas are characterized by poor access to clean drinking water

Water sources (boreholes, wells etc) often suffer suffer micro-biological contamination and are polluted by salt

These projects are often small scale and involve the installation or rehabilitation of water supply and/or purification systems, typically solar powered

This removes the need to boil water using local fuels

Rehabilitating hand operated bore water pumps provides multiple benefits to local community
Rehabilitating hand operated bore water pumps provides multiple benefits to local community

Reduced demand for fuel lowers forest biomass removal, helping maintain biodiversity

Helps improve hygiene, social, economic and environmental issues

Reduced indoor air pollution improves health of people in the household

Water-borne diseases due to unsafe drinking water successfully addressed

Projects help raise hygiene awareness among local population

Safe Water (Filtration)

Point-of-use water filters treat contaminated drinking water

Microbiological purifier delivers clean drinking water

Requires no electricity or additional consumables beyond the unit itself

Removes the need to boil water using non-renewable biomass

Carbon finance is helping provide a significant improvement in public health

Children holding water filters that provide clean water

Avoids firewood and charcoal being burned, slowing deforestation and degradation

Reducing pressure on local forests helps maintain biodiversity

Reduced incidence of waterborne diseases, especially among under 5’s

Women and children spend less time gathering and carrying firewood

Improved indoor air quality from not burning firewood to heat water

Autoclaved Aerated Concrete (AAC) Blocks

AAC blocks are high-quality walling and wall insulating building materials

Produced using an efficient, low energy intensive brick production process, unlike brick trench kilns

AAC blocks don’t require any sintering or kiln heating for block consolidation

Sintering or firing ‘green’ bricks in a kiln uses large amounts of thermal energy, usually fossil fuel

While AAC blocks do require electricity and steam generation, the energy use is much less than brick kilns’ use

Example of autoclaves - autoclaves are used to manufacture AAC blocks
Example of energy efficient autoclaves. Autoclaves are used to manufacture AAC blocks, replacing traditional brickmaking kilns

AAC blocks use waste materials or by-products from other industries; an example of circular economy

Manufacturing process creates employment for large numbers of skilled and unskilled people

Local and regional air quality improved

AAC blocks are energy efficient, provide 6-10 times better thermal insulation than regular concrete

Non-toxic, fire resistant, excellent sound absorption and low density lightweight building material
