Waste heat accounts for a painful 60% of the gasoline consumed by our cars, and in other Industrial applications the numbers are equally devastating.

After years of research by Intel and Micron Technology, the first new memory technology in 25 years has been announced. Called 3D XPoint it combines the best of DRAM and NAND (Flash) and promises to change computer designs.

The project is part of the local authority’s commitment to Bristol 2015 European Green Capital. The city has also installed a sculpture of two life size whales made from recycled bottles, marking the city’s green status.

The US Department of Agriculture (USDA) is investing $63 million (£41) in 264 energy efficiency and renewable projects across the country.

London Mayor Boris Johnson has launched a tool for public sector organisations to make homes more energy efficient.

The Business Energy Challenge (BEC) awards celebrate private sector firms who have made the biggest difference to their energy consumption by switching to cleaner and more energy efficient technologies.

The scheme allowed householders to make their homes more energy efficient by installing technologies such as solar panels or loft insulation. This was done through loans with no upfront cost which were repaid through energy bills.

A London school is expected to save nearly £5,000 a year on energy costs as a result of installing energy efficient measures.

It is the saved power output of the Hanoi Electricity Corporation (EVNHANOI) in July. Accumulated figure for the first 7 months of the year shows that the Corporation achieves 177.35 million kWh savings, equivalent to 2.22% commercial power output.

At the workshop, large energy consumers and experts in the field of power saving shared experience and new technology solutions to reduce the energy consumption rate, energy audits and improvement of the production system, and power consuming devices.

That is one of the objectives of the Economical and efficient use of energy Program of Bac Giang province for the phase 2016 - 2020 .

The Launching Ceremony is a practical activity aiming at implementing the National Target Program on Economical and Efficient Use of Energy as it has been widely deployed in the province.

As one of the pillars of national power energy security, in 2011-2015, Electricity of Vietnam (EVN) not only ensures enough electricity for the economy but also stays in the lead in the implementation of solutions and promotions of economical and efficient use energy.

Currently, electricity consumption for lighting in Vietnam accounts for 35% of total power consumption of the country. The public lighting system is energy-consuming sector due to the design, installation and use of inefficient lighting.

In the implementation of energy development strategy, Ministry of Industry and Trade presided over the preparation of policies to support the development of renewable energy sources such as wind power, biomass power, electricity generated from solid wastes and solar power.

Not simply to raise awareness, it is to change behavior. After 3 years of operation, the project GetGreen Vietnam has been completed with its targets: to get 1,099 "Seeds of Change" persons trained, a contribution into spreading the habit "green consumption", "green living" in the community.

Representatives of the Ministry of Construction reveal that buildings consume more than 30% of total energy consumption in the fast growing economy. Thus improving the energy efficiency for the new construction is an urgent requirement.

26.8 million kWh, equivalent to VND42 billion - not a small figure which represents great efforts of Da Nang Power Company in its effective power-saving solutions for the first 6 months of 2015.

Three eco-friendly pioneers are heading off on the journey of a lifetime - a 20,000km (12,427 mile) ride in a solar-powered tuk tuk from Bangkok to Toulouse, France.

While the cost of solar power has dropped significantly from the early 2000s, there is still plenty of room for the technology to become cheaper, making it even more attractive as a substitute for fossil fuels.
