Beacon Power, a major player in flywheel energy storage, is now working with U.S. Department of Energy’s Advanced Research Projects Agency – Energy (ARPA-E) on the development of a next-generation of flywheel storage. The new flywheel storage system is expected to be able to store 4 times as much energy as present flywheels, and at one-eighth the per kilowatt-hour cost.

Utilizing what we have in a wiser way could lead us to something worth it. As the famous line goes, “everything has its purpose” no matter how small or big it is. It also includes waste products such the awful pet poop, specifically dog poop. In Cambridge, Massachusetts, a dog park hasn’t been considering these dog poop a waste at all. In fact, in has turned out to be a very useful.

Designed by the Tokyo Institute of Technology and fine-tuned by researchers at MERSTech in partnership with the ONR's office in Tokyo, the Magnetic Energy Recovery Switch (MERS) harnesses and recycles residual magnetic power that is produced by electrical current. By using a device that controls the flow of electricity, light bulbs can now maximize their potential. The proposal for the expanded experiment is scheduled for completion in October.

According to the Pedegopress release , “The announced battery-fuel cell hybrid system is compatible with all existing Pedego bicycles and batteries. For every 1.5 lbs. of weight a rider carries, an additional 700 watt-hours of energy is available (compared to ~350 watt-hours for an ultra-high performance lithium-polymer battery at a weight of 7 lbs.).

Anywhere people are walking dogs -- and throwing away dog poop -- can be a source of heat and light by introducing a methane digester into the equation. The first-ever Park Spark project was installed in Cambridge, Mass., on Tudor Street, between Sidney Street and Brookline Street, a few blocks from MIT.

Advances in solar energy efficiencies have so far been made with irregular surfaces, thinner tabbing between cells, more optically perfect glass and even special coatings, but now Stanford engineers say the best efficiency is via ultra-thinpolymer films inside solar cells that allow more “bounce room.”

The inventor says his device can cut the energy use by 25%. Moreover, it can prove itself healthy for those who suffer from asthma, allergies, of whatever age or sex. CleanAir supposedly removes particles, viruses, ozone, bacteria, organic solvents, hydrocarbons and cigarette smoke from the air.

All new investments must undergo independent assessments and government reviews on whether they are energy-saving or not before being approved by regulators, the National Development and Reform Commission, China's top economic planner, said yesterday in a statement on its website.

Vertical axis wind turbines have recently been revived by a few innovations made to them by scientists all over the world. Sauer Energy is one of them, and their turbine has a high efficiency because it’s designed to maximize the drag, so the blades are moved more efficiently by the wind.

Last year, the Ocean Power Technologies (OPT) company has developed a tidal power generator that has now been connected to the energy grid at the Marine Corps Base Hawaii as part of the firm’s program with the US Navy to test wave energy technology, giving the US their the first-ever grid connection for a wave energy device.

The phase-out of incandescent light bulbs is part of the EU's strategy to cut greenhouse gases by 20% by 2020. Replacing the old lamps with more efficient models is expected to reduce energy consumption for lighting by 60% in the EU, equivalent to saving 30 million tons of CO2 pollution every year.

Ahead of the 2020 deadline for constituent parts of the UK to hit renewable power targets, Scotland has raised its ambitions for real-terms energy saving by switching to eco-friendly alternatives.

A delegation representing 15 Finnish enterprises said here on Tuesday they wanted to look for local partners to develop renewable energy, wastewater treatment, industrial waste management and other environmental technologies. Some of the Finnish companies introduced their clean technologies at a seminar held here on Tuesday were Neste Oil Corporation, Cargotec, GD Power, Kemira, Fincumet, YIT and Outotec.

If, in common sense, a buck saved is a buck earned, this proves all the more significant in energy savings, when a sum invested may result in higher profits and higher benefits. If, for an individual, energy saving merely means to avoid money burning big holes in his or her pocket, then for a company, it means better returns and better business efficiency, and for an economy, there are even greater dimensions of cost-effectiveness.

Realizing that natural resources are limited, Holcim Vietnam Limited since 2003 has aimed at sustainable production development by increasing the use of waste materials as main energies to replace fossil fuels at its Hon Chong cement plant in Kien Giang Province.

Apart from awareness in all the company, LaVie has also decided to invest in new technology as a way to reduce energy consumption. The deputy general director reveals that her company will replace all energy-consuming air compressors by smaller ones that fit the capacities of the current production lines. In addition, it has changed its lighting systems to LED lamps, and reduced water use as a way to cut energy consumption as well.

The UK environmental group Carbon Trust and Cambridge University’s Cavendish Laboratory have jointly formed a new company called Eight19 concentrating on the development of new organic photovoltaic (PV) technology that could make the installation of solar cells cheaper and easier.

We all know LED as being the flagship of green lighting, but what if those so-called “efficient” LEDs turned out to be even more energy-effective under certain conditions? The Kyoto University, in collaboration with Stanley Electric Co Ltd found a way to increase the emission intensity of silicon-based thin films by several times.

Along with urban growth, the demand for use of energy in urban areas has increased rapidly, especially in big cities such as Hanoi, Hai Phong, Ho Chi Minh City, Da Nang and Nha Trang. In such circumstances, using solar energy is considered to be a solution that will help reduce energy consumption in urban areas and prevent climate change. This solution was discussed at a workshop themed 'Climate change and sustainable urban development in Vietnam' that was held recently in Hanoi.

Authorities have pledged to speed up construction of green buildings in response to the surge in building energy consumption that has resulted from the country's rapid urbanization. Li Bingren, chief economist at the Ministry of Housing and Urban-Rural Development (MHURD), said at a press conference Monday that authorities had made numerous efforts to save energy and reduce emissions, yet energy use efficiency remains low.
