This technology seems to me to be much more beneficial on a local scale, what if every home had its own battery, then home power generation becomes economically more viable for everyone. If you could show that a system like this could pay for itself in say 5 years then every home would want one. Plus for this to be implemented on a large scale requires massive investment that could be decades away. Share the technology and lets get it in homes by next year. Great ted talk. Jon Senior 0 Reply 1 hour ago: I agree 100%. Localised energy production would also make energy consumers more conscious of their consumption and encourage efforts to reduce it. We can invent and invent all we want, but the fast solution to allowing renewable energies to take centre stage is to reduce the base energy draw. With lower baseline consumption, smaller "always on" generators are required to keep the grid operational. Town and house-l

The current growth in the local and international engineering, civils and construction markets is expected to continue despite the current volatility experi- enced in world economic markets, reports the South African Association of Consulting Engineers (Saace). Saace CEO Graham Pirie says that even though the local infrastructure roll-out programme and the infrastructure investments from emerging markets such as China were initiated before the period of global market volatility, infrastructure builds cannot be halted as they are vital to the economic growth of countries. "Government's commitment of R500-bil-lion, in addition to the money invested in the 2010 FIFA World Cup stadiums, to be spent over three years, means that 2010 is a small component of a larger investment that government is encouraging," says Pirie. He comments that the infrastructure roll-out programme is necessary, given the 20-year infrastructure investment backlog that South Africa needs to resolve. Pirie says that events hosted in the country since 1994 have encouraged infrastructure reinvestment. "Prior to 1994, South Africa didn't host sporting or political events that would draw an influx of tourists into the country, so the need for infrastructure reinvestment was minimal. "From 1994, with the 1995 rugby World Cup looming, government got serious about resolving this. Certain sporting events, such as the 1995 rugby World Cup, the 2003 cricket World Cup and the 2010 soccer World Cup, focus the right amount of attention on infras- tructure reinvestment at the right time," says Pirie

The redeveloped World Trade Center will be "one of the largest fuel cell installations in the world" according to the New York Power Authority (NYPA). Under the US$10.6 million agreement between NYPA and fuel cell developer and provider UTC Power, fuel cells with a total capacity of 4.8MW will provide an on-site supplement to the renewable and other clean energy that will power the rebuilt centre. The first fuel cells will be delivered to the Freedom Tower in January 2009, and will be owned and operated by the Port Authority, which also owns the building. The fuel cells for the other three towers will be owned and operated by World Trade Center Properties, LLC. "Fuel cells are one of the environmentally beneficial technologies that the Power Authority is investing in under Governor Paterson's leadership to combat greenhouse gas emissions and diversify the state's energy mix. To date, we've installed 15 fuel cells in New York City and other locations, and expect to add to this total in support of the Governor's ambitious goals for significant increases in the state's renewable power," says Roger B Kelley, NYPA President and Chief Executive Officer.

Led by China, the developing nations of the world now consume more energy than the industrialized countries, according to the 2009 BP Statistical Review of World Energy. BP released its annual review of world energy use on June 10, noting that industrialized countries reduced their energy consumption by 1.3% in 2008, led by a 2.8% drop in the United States, marking the country's steepest single-year decline since 1982. That decrease was counterbalanced by increasing energy use in developing countries, which caused global energy consumption to increase by 1.4%.

IEA's dire warning on green stimulus and renewables Kate Mackenzie, Financial Times The IEA's report for G8 energy ministers, to be presented this Sunday in Rome, has generated a few stories. Some picked up on the oil supply squeeze that awaits the world due to massive cuts in production investment. I wrote yesterday that the IEA forecasts that, for the first time since World War II, world electricity consumption will decline in 2009. IEA chief economist Fatih Birol said he personally thought the electricity forecast was the most striking finding of the report. However he was also keen to highlight concern about green spending in the G20 stimulus packages: The agency will also tell ministers that its calculation of the stimulus spending required from G20 nations on renewable energy was inadequate and should rise by a factor of six if greenhouse gas emissions targets set by the United Nations were to be met...

ICSG 1 Feb 09 - Based on existing facilities and announced project developments, annual mine production capacity in the period 2009-2013 is expected to grow at an average rate of around 4.3% per year (%/yr) to reach 23.1 Mt in 2013, an increase of around 3.6 Mt (19%) from that in 2009. Of the total increase, copper in concentrate capacity is expected to increase by 2.7Mt (4.3%/yr) to reach 17.9 Mt and solvent extraction-electrowinning (SX-EW) production by 820,000t (4.4%/yr) to reach 5.2 Mt. Most of the new mine projects and expansions are located in Brazil, Chile, Congo, Mongolia, Peru, the United States and Zambia, which together account for around 2.6 Mt (73%) of the projected mine capacity increase during this period. Annual smelter capacity is projected to grow by an average of 2.6%/yr to reach 20.2 Mt in 2013, an increase of 2 Mt (11%) from that in 2009. Asia will be the leading contributor to growth (1.8 Mt), with expansions and new projects expected mostly in China, but also in India, Indonesia and Iran. Africa is the second leading contributor owing to developments in Zambia. North American smelting capacity will fall by 12% (250kt) due to closures of plants in Canada. The ICSG tabulations indicate that world refinery capacity will reach 26.6 Mt in 2013, an increase of 3.2 Mt (13%) from that in 2009. About 2.3 Mt of the expansion is expected to come from electrolytic refineries and 820,000t from electrowinning capacity. Electrolytic refinery capacity growth is projected to average 3.1%/yr, exceeding the projected growth in smelter capacity, and electrowinning capacity growth (at the refinery level) is expected to average 4.3%/yr. About one half (1.5 Mt) of the world refinery capacity increase during this period is expected to come from electrolytic refineries in China; about 25% (830,000 t) from electrolytic capacity increases in India, Indonesia and Iran; and about 20% (600,000 t) from electrowinning capacity increases in Congo, Peru and Zambia.

"Regulatory cooperation at regional, continental and world level is a trend which is set to continue. The International Confederation of Energy Regulators (ICER), which brings together more than 200 regulators from around the world has proved to be a very valuable platform for the exchange of good regulatory practice and facilitating regulatory cooperation. "

Unless there is a shift in world energy policies, global energy demand is set to accelerate, putting increasing strain on the world economy and the environment.

\nCadiz, Spain - While significant challenges remain and large-scale applications appear relatively far out on the horizon, smaller scale applications, such as organic light emitting diodes (OLEDs), are already being built into a variety of electronic products. Industry pioneers, such as G24i, have begun manufacturing their first generation of products, which in G24i's case includes a DSC-powered mobile phone charger and an award-winning "Lighting Africa" portable lamp that marries cutting-edge LED and dye-sensitized thin-film PV technologies. \n\nLooking to bring off-grid electrical power options to people in Kenya, Nigeria, Rwanda, South Africa and a still growing range of African countries, G24i in May was awarded the World Bank Group's 2008 "Lighting Africa Development Marketplace" prize for its solar-powered LED light, which uses the company's proprietary dye-sensitized thin-film solar cells in concert with light emitting diodes (LED) produced by Dutch lighting manufacturer Lemnis. \n\nG24i dye-sensitized thin-film solar cells are proving themselves rugged enough to endure some of the harshest conditions on the planet. Besides enduring the rigors of operating in various African locations, the company's DSC cells were used to generate electrical power for British explorer Robert Swan and his team during their two-week 'E-Base Goes Live' project in which they traveled to Antarctica. Despite poor sunlight, the cells contributed to the successful powering of satellite, digital and video conferencing and other communications equipment throughout the two-week long expedition.\n\nThe first person to walk to the North and South Poles, Swan is moving on to an educational sailing around the world project and G24i is working on sails for his craft that will have thin-film dye-sensitized PV cells embedded in them. \n

"Everything that is important to this world will be solved by semiconductor technology." That was the claim of National Semiconductor CEO and Chairman Brian Halla at the EcoChip forum hosted at chip-maker Actel's Silicon Valley campus Monday. It's a tall order, of course, not least of all for an industry expecting to see its annual sales plummet by 5.6 percent to $246.7 billion in 2009 compared to 2008. For the fourth quarter alone, the Semiconductor Industry Association anticipates sales will drop 5.9 percent from the previous quarter.

The American Council for an Energy-Efficient Economy issued a report yesterday touting the role that semiconductor-based technologies have played in making the U.S. economy more efficient. At the same time, the International Energy Agency issued its own report calling on governments around the world to be more aggressive with efficiency standards for ICT and consumer electronics, which are expected to demand twice as much power by 2022 and three times as much by 2030 - creating a need for another 280 gigawatts of power generation (i.e. like adding another Japan to the world, or more than 230 nuclear reactors). "This will jeopardize efforts to increase energy security and reduce the emission of greenhouse gases," according to an IEA news brief.

"Globally, Bloomberg New Energy Finance expects $7.7 trillion to be invested in new generating capacity by 2030, with 66% of that going on renewable technologies including hydro. Out of the $5.1 trillion to be spent on renewables, Asia-Pacific will account for $2.5 trillion, the Americas $816bn, Europe $967bn and the rest of the world including Middle East and Africa $818bn. Fossil fuels will retain the biggest share of power generation by 2030 at 44%, albeit down from 64% in 2013. Some 1,073GW of new coal, gas and oil capacity worldwide will be added over the next 16 years, excluding replacement plant."

" China is also planning to build trillions of dollars of infrastructure for the entire world over the next few decades."

"The collapse of key energy policy pillars of Barroso's decade 1. The world has cheaper and more abundant fossil fuels than expected. 2. The EU internal Market conceived for gas-fuelled plants competition (CCGTs) has to deal with a fierce RES subsidised push. 3. The EU Green Revolution (to push us as world R&D and leading manufacturer of a decade-long green growth) is gone. 4. Carbon pricing originated in the EU and was adopted to some degree here and there but ceased to offer any incentive to change the EU vis-à-vis GHG emissions. 5. The EU Supply Security is lower than at the fall of the Soviet Union, or before the Bush-Blair invasion in Iraq; and the EU has to address it by itself. Then what are the key components that can put EU energy policy back on track toward reaching our 2020-2030 goals? The following policy brief offers a new vision of the energy policy for our new Commission from an independent, academic point of view."
