As energy-efficient heating, lighting and ventilation systems become standard, developers will benefit from huge cost savings.

Contemporary stoves continue to blossom into decorative furnishings as well as energy-efficient heating devices.

The most obvious ways to green up an office - installing energy-efficient heating and lighting, and updating printers so that they can double-print - are out of our hands.

There are also ranges that get the most out of energy-efficient heating systems, such as ground-source or air-source heat pumps.

Installations of energy-efficient heating measures we have delivered nationwide have more than doubled since 2016.

We wanted the most energy-efficient home possible, and have invested in that.

They plan to turn it into an energy-efficient home for themselves and a business centre for teaching environmentally-friendly building techniques.

It now focuses on urban regeneration, returning brownfield land to productive use by building energy-efficient homes in landscaped settings.

In a sizeable section on making buildings greener, the group suggests cutting stamp duty and council tax for more energy-efficient homes and offices.

Over 90% of its developments use brownfield land for energy-efficient homes in landscaped settings.

Energy-efficient light bulbs last up to ten times longer and use a fraction of the power required by ordinary bulbs.

Energy-efficient light bulbs, for example, do not work on dimmer switches and are still more expensive than their less efficient counterparts.

I thought that installing energy-efficient light bulbs would be the easiest energy-saving measure.

This would most obviously apply to energy-efficient light bulbs but could also include the most energy-efficient televisions, washing machines and so on.

She also tries to be vigilant about energy use, switching appliances off at the socket and using energy-efficient light bulbs.

There are also water-saving devices, energy efficient lighting and double-glazing throughout.

Companies and households could also be rewarded for installing energy efficient lighting, for example.

Three years later, the building underwent its first major renovation when energy efficient lighting was installed.

Integrated design uses daylight to reduce electrical demand, and incorporates energy efficient lighting, motors, and equipment.

The free service reduces utility costs and carbon emissions simultaneously by switching low and fixed income households to energy efficient lighting.

As technology improves, the s most energy-efficient product at the time of purchase can soon become the most energy-inefficient product.

Several issues it addresses include: metering and reporting, energy-efficient product procurement, energy savings performance contracts, building performance standards, renewable energy requirements, and alternative fuel use.

It's the quick and easy way to spot the most energy-efficient products on the market.

Government agencies could be required to procure energy-efficient products.

Some even argue that producing energy-efficient products, such as light bulbs, actually simulate more demand, resulting in more energy being purchased for conversion into light of the same strength.

Achieving that target will require a major shift toward alternative energies and energy-efficient technology.

Some sceptics argue that continued growth in the market for low-carbon, energy-efficient technologies will depend on continued high prices for both oil and carbon.

If low-carbon, energy-efficient technologies grow to just 10% of this over the next 45 years, that's a $645 billion market.

The university encourages green purchasing when possible including installing energy-efficient technologies around campus such as steam trap systems and economizers.

Volunteers across the world have raised ecological awareness and promoted conservation by employing energy-efficient technologies and organizing large-scale tree planting campaigns and recycling programs.
