Green Square has a solar power system with capacity of 212 kWp and is connected to the building grid. The building is also a part of Big C supermarket which is considered as the first Green Supermarket in Vietnam.

The building with low building density around 50% is covered by surrounding ventilation, so it frequently receives winds all year round. The cool wind blow around the campus of the building that has created the comfortable feeling for everyone and helped cool the surface of the work.

Researchers have used the pigments in cuttlefish ink to create edible, dissolvable batteries, which could provide a safe, biocompatible source of energy for implanted medical devices.

PanaHome, a subsidiary of Panasonic Electronics Company (Japan), exhibited a house where the roof is made of solar battery panels.

Scientists at the Institute of Big Bang, England have used plants to capture energy and help illuminate the decorative bulbs on the Christmas pines. These pines will be placed in the Southbank (London) to create a spectacular sight for the first time in the world.

By placing a network of unmanned drones at high altitudes, a UK firm hopes to harvest energy from a variety of sources for transmission to ground-based receiving stations.

German designer Johannes Kiessler invented a kind of the hanging electric lamp with strange, nice shape; its outside box is made of cardboards. Therefore, it is environmentally friendly.

The major energy for operation of high-speed railway is wind energy, at the station, will use solar energy without using the national grid.

Steam engine technology could provide an inexpensive option for solar power storage, bringing the cost of storing the energy down to a fraction of that of current battery storage solutions.

A wireless device developed by researchers at Duke University that converts microwaves into electricity could eventually harvest Wi-Fi or satellite signals for power, according to its creators. It could also one day be built into cell phones to let them charge while not in use, they say.
