Solar Junction is a 4-year-old company spun out of Stanford University that designs high-efficiency, multi-junction solar cells for concentrating photovoltaic (CPV) solar collectors. The National Renewable Energy Laboratory recently certified that its solar cells can operate at 40.9% efficiency, a significantly higher efficiency than typical silicon solar cells that convert sunlight to electricity at an efficiency of about 15-20%.

Implementing the Power VI plan approved by the Government, the Electricity of Vietnam (EVN) is striving to accelerate the construction and complete the whole Son La hydropower project (capacity of 2,400 MW) at the end of 2012. In the short term, in 2011, EVN has planned to power on unit 2 on Apr 30th; unit 3 on Aug 31st and unit 4 on Dec 31st.

Clearing up the regulatory hurdles that are slowing development of electricity transmission lines would provide a significant boost to U.S. wind power development, industry officials said Wednesday. The American Wind Energy Association is holding a two-day workshop in Omaha focused on the challenges of transmitting power to places that need it. The biggest regulatory barriers have to do with who pays for high-voltage transmission lines and who decides where the lines will go.

Thus, from March 1st, the average price of electricity will increase from 1,077vnd/kWh to 1.242vnd/kWh, equivalent to a 15.28% increase. With this increase, many of EVN’s costs shall continue to be kept from being allocated to the price, the rate of return on state capital of EVN is zero and coal price has not risen in the electricity price structure.

Award winning Israeli company Solaris Synergy has designed solar energy grids that can float on water, reducing energy production costs, and preventing water loss. Generating energy from the sun would be more practical if not for two huge drawbacks: The expense of the silicon material that converts light to electricity, and the large tracts of land needed for solar farms.

People were skeptical when the idea was first floated about a year ago, says Nick Getzen, spokesman for The Jobs Project, which is trying to create renewable energy job opportunities in West Virginia and Kentucky. In the southern coalfields, he says, people have only ever gotten electricity one way – from coal-fired power plants.

The director of the Energy Intensive Users Group, Jeremy Nicholson has said that failure of wind how has very profound implications. This comes after new figures have shown that during the recent cold period, wind power produced less than two percent of the nation’s electricity. He says that because of this, the government will encourage companies to build back up stations in case of further failures.

You might dream of living off the grid someday, but for billions of people around the world, it's a reality and not a choice. The International Energy Agency estimates that when the Earth's population exeeds 8 billion around 2030, 1.3 billion will still live without electricity. Of those, 700 million will be in Africa.

Electricity of Vietnam (EVN) Group yesterday officially started construction on the second turbine of Song Tranh 2 hydropower plant with designed capacity of 95MW.
The Song Tranh 2 hydropower plant project has been conducted by EVN Group as the main investor. It's the second hydropower plant to be built on Vu Gia-Thu Bon river system. It is expected that the hydropower plant will produce annual electricity output of 679.6 million KWh to join the national grid.

In conventional photoelectrochemical cells, sunlight is converted into electricity and an electrolyte is used to move electrons which creates a current. The problem is that these cells have chromophores, which are light-absorbing dyes that degrade after being exposed to sunlight. But with self-repairing solar cells, this would no longer be an issue. To create these new solar cells, the Purdue research team utilized two crucial elements needed to make this technology imitate nature, which was molecular recognition and thermodynamic metastability. This allows the system to be dissolved and reassembled on a regular basis, replacing photo-damaged dyes continuously.

Wind power rose by 18.5 per cent in 2010 and now meets 16 per cent of demand. Luis Atienza, managing director of Spain's electricity grid, predicted that "within three years wind power will overtake nuclear as an electricity source". At its peak, on November 9, wind power met 43 per cent of demand.

Ontario residents will see a 10 per cent rebate on electricity costs for the next five years, starting January 2011, the province announced on Nov. 18. The Ontario Clean Energy Benefit is intended to help Ontarians cope with rising hydro costs, Sudbury MPP Rick Bartolucci stated in a press release. "This is more than the provincial portion of the HST and will help the average family save more than $100 per year in hydro costs," he added.

According to the company’s statements, the tall building will have a wind tunnel in the middle . The air will be converted to electricity as soon as it gets down to a series of turbines. The Betz limit value theory says that the maximum harvestable energy from the wind is 59.3% but the company claims that the system is not constrained by it.

Electricity of Vietnam (EVN) Group announced that there will be additional 2 billion KWh to be supplied to national grid by Son La hydropower plant and Song Tranh 2 hydropower plant. On January 7, 2011, EVN will officially put into operation the first turbine of Son La hydropower plant after over five years of construction. At the same time, the group will also have the first turbine of Song Tranh 2 hydropower plant joined the national grid.

Bulgaria will export an estimated 7500GWh of electricity in 2010, more than double its 2009 figure of 3700GWh, announced the National Electric Company (NEK). This represents 21.6% of total power generated in the country. Exports have increased significantly as domestic consumption was reduced by the recession. “We reached an all-time exports record this year,” Parvanov said. “Mainly because we improved the management of the tenders and our product.”

According to a recently released report, Scotland is on track to meet its ambitious renewable energy goal of generating 80 percent of its electricity from renewable energy sources by 2020. In the report, Energy Trends, it was revealed that 27 percent of the electricity in 2009 was generated using renewable energy sources.

Sweden and Norway have agreed the bases for a common green certificate market, energy ministers for both nations said on Wednesday. A green certificate is a tradable commodity proving that a certain electricity has been produced using a renewable source of energy, such as wind, solar or hydropower. Environmental groups hope they can boost the use of renewables.

Korea is set to build 14 nuclear power plants by the year 2024 in an attempt to lessen its reliance on petroleum for electricity. At a public hearing in Seoul on Tuesday the Korean government announced a long-term plan for energy which calls for an increase in the portion generated through nuclear plants and renewable sources.

A sprawling international collaboration between scientists at government and university laboratories has resulted in a breakthrough discovery that could lead to more efficient ways of generating electricity from waste heat. The phenomenon, called the thermoelectric effect, can be applied to car exhaust, factory emissions, and other operations to capture the large amount of human-manufactured energy that is currently lost to the atmosphere.
