The United States is on the verge of a solar boom that could provide 4.3 percent of the nation's electricity by 2020, according to a new report from Bloomberg New Energy Finance. There's just a 12-figure catch: Investors need to put $100 billion into the solar industry to keep the generation of solar electricity growing by 42 percent a year for the next decade to expand capacity from the current 1.4 gigawatts to 44 gigawatts.

Siemens has landed an order to supply 80 wind turbines for the Dan Tysk wind farm off Germany's North Sea coast. With a total capacity of 288 MW, the farm will begin supplying clean electricity to 500,000 German households in 2014. Dan Tysk Offshore Wind GmbH is owned by Vattenfall Europe with a 51 percent stake and Stadtwerke Munchen with a 49 percent stake.

Works such as leveling an area of 251ha, building bypass road south of Hau river, compensating and site clearing, resettling 315 households… have been completed. The constructions of roads, electricity system, water supply system, embankments along Hau river in the plant construction site and coal slag dumping area ... are being expeditiously implemented to be completed on schedule.

We’ve been talking a while ago about Michael Strano and his thin carbon nanotubes that can transform fuel poured onto them into electricity. A chemical reaction is set up by heating the nanotubes, triggering the transformation at a speed of 10 meters per second.

With the second largest tidal range in the world, about 50 feet, the Severn estuary has been eyed for years as a potential energy source, particularly as the appetite for sustainable energy sources has been growing over the last few years. The U.K. has pledged to have 40 percent of its electricity generated from renewable sources by 2020 to meet European Union requirements.

The ‘Global Wind Energy Outlook 2010’ (GWEO 2010) finds that wind power could play a key role in satisfying the world’s increasing power demand, while at the same time achieving major greenhouse gas emissions reductions. The 1,000 GW of wind power capacity projected to be installed by 2020 would save as much as 1.5 billion tonnes of CO2 every year.

After participating in the GE Ecomagination Challenge and winning $50,000, Scott Brusaw and his wife Julie Brusaw are much more optimistic in what concerns their Solar Roadways project, which aims to make the road produce electricity through embedded solar panels.

A workshop was held recently by a gas engine research team of the Da Nang University with support of Toyota Motor Vietnam (TMV) through the Go Green Program to assess the results of the implementation of the second stage of the project titled “Small-scaled Electricity Production from Biogas” in some provinces of central Vietnam.

China's top economic planner is proposing graduated tariffs on residential electricity use as part of the nation's efforts to save energy, the National Development and Reform Commission said Saturday on its website. "A graduated mechanism will improve China's power tariff structure and spur energy conservation," the economic planning body said.

In Chau Khe, Dinh Bang (Bac Ninh Province), more than 800 households are involved in iron and steel production. To temper and laminate steel, they consume about 200 million kWh of electricity and 30,000 tonnes of coal, and total expenditure on energy consumption amounts to VND150 billion each year. Such high energy consumption is attributed to the use of outdated technologies and equipment as well as insulated steel furnaces. At some stages of steel production, the rate of energy losses is 20-25 percent.

Dr. Nguyen The Hung from the Institute of Physics under the Vietnam Academy of Science and Technology said that many other countries in the world have successfully converted photo energy into electrical and thermal energy.

In honor of Blog Action Day on the topic of water, here is a bit of good news about a new low-cost, energy efficient method for purifying drinking water without the use of chlorine. Scientists at Stanford University have developed a new kind of water filter that uses a combination of silver, cotton, and electricity to kill up to 98 percent of E. coli bacteria in contaminated water. The system was recently described in the American Chemical Society journal.

With rapid industrialization, the world has seen the development of a number of items or units, which generate heat. Until now this heat has often been treated as a waste, making people wonder if this enormous heat being generated can be transformed into a source of electric power. Now, with the physicists at the University of Arizona finding new ways to harvest energy through heat, this dream is actually going to become a reality.

After renewing the house, Mr Hieu and his wife decide to reuse the decorative since they thought it is still very new. However, being put into use, the chandelier has caused a complicated problem as it consumes a lot of electricity and is very hot. The chandelier has three tiers, with about 26 40W bulbs, so it consumes 1.040W per lighting hour. Then the chandelier has been“retired” once again after a month.

According to the latest data from the Bundesnetzagentur, Germany's solar industry added another 1,000 MW during July and August. This brings the total for the eight-month period from January through August to 4,900 MW from nearly 175,000 solar installations.

The cells that power the bicycle use sodium silicide, a powder similar to sand. In combination with water, the substance “instantly creates hydrogen gas”, that is further on used to generate energy. Moreover, excess electricity is stored in batteries that are safe and fully recyclable.

Struggling to tackle the acute power crisis in the state, Shobha Karandjale, the new energy minister, is planning to encourage energy conservation as purchasing electricity is proving to be a costly affair. The government spends an average of Rs 350 crore a month to purchase power from private producers to meet the power crisis.

The latest official figures from the Department of Energy and Climate Change (DECC) could provide insight into how energy saving aspirations across the UK have affected power consumption. In its second quarter 2010 report, DECC notes a 24 per cent fall in primary electricity consumption across the country.

According to the Danish climate commission, the country will gets its electricity from wind farms, developing an energy network entirely free of fossil fuels by 2050. The committee also said that biomass and wind energy could meet the bulk of the country’s energy requirements.

The conference is to assess the results of the phase II of the project "Production of small scale electricity from biogas" in some central provinces, conducted by the air engine researching team of the University of Da Nang (UD) with the support of Toyota Motor Vietnam (TMV) through the Go Green program.
