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

General Motors Corp., along with a consortium of more than 30 utilities and a non-profit electric industry research group, has struck a deal to forestall potential problems when the company introduces its new electric vehicle to the nation's showrooms. An EPRI official also emphasized the grid aspects of the collaboration. Said Arshad Mansoor, the organization's vice president of power delivery: "Seemless integration of [plug-in hybrid electric vehicles] into the electric grid will require close collaboration between the automobile and electric sectors." The statements from EPRI and the car company also address safe and convenient vehicle charging, public education and other public policies, including codes and standards. Among the utility participants in the collaboration are Consolidated Edison of New York, Duke Energy, First Energy Corp., Pacific Gas & Electric Co. and Southern California Edison Co. Others are listed as part of the EPRI statement. The research organization last year released a report along with the Natural Resources Defense Council that concluded plug-in hybrids had the potential to lower greenhouse gas emissions. GM, meanwhile, emphasized the cost benefit of the new vehicles, saying consumers could find that the per-mile expense of an electric vehicle would be about one-fifth that of a gas-powered car.

"The IEA estimates that of all efforts required to deliver a 50% reduction in global emissions by 2050 24% will need to come from end use fuel efficiency, 12% has to come from end use electricity efficiency and a further 7% will need to come from power generation efficiency. There is substantial potential for improving thermal efficiency of Europe's power plants. Our coal plants operate at an average 38% (BAT - Best Available Technology - on new coal plants delivers 46%). Our gas plants operate at an average of 52% efficiency (BAT- Best Available Technology - on new gas plants delivers more than 60%). Due to the age of the installed base, the average efficiency of Chinese coal plants is now higher than in Europe."

LONDON, UK, August 12, 2008. Analyst New Energy Finance says the days of easy carbon trading may be over as the low hanging fruit of the cheap carbon credits in the developing world have now been harvested. To date, the cheapest way of reducing greenhouse gas (GHG) emissions have come from projects eliminating high global warming potential (GWP) gases in developing countries, notably China. These projects involve the destruction of two waste gases from industrial facilities: the hydrofluorocarbon HFC-23 and nitrous dioxide, or 'laughing gas' (N2O), both of which are several thousand times more potent in terms of global warming that CO2. The size of the emissions reductions achievable from these projects relative to the scale of the investment required, that these carbon credits are so cheap - around €1/tCO2e. In comparison, costs claimed by project developers of renewable energy and energy efficiency projects are €5-15 per tonne and the global market price for carbon countries from developing countries are around €20/tCO2e.

The electricity sector accounts for almost 35 percent of greenhouse gas (GHG) emissions in the United States, and 40 percent of the carbon dioxide (CO2) emissions. Over 80 percent of GHG emissions associated with electricity generation are from the combustion of coal, with nearly all the rest due to natural gas and petroleum combustion. U.S. electricity sales are split among the residential (37 percent), commercial (36 percent), and industrial (27 percent) sectors, where primary uses vary by sector. Over the past 30 years the U.S. electricity sector has become less carbon intensive, and the U.S. economy has grown less electricity-intensive.

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.

Wind power is the most mature of mainstream renewable energy technologies and, if the world's electricity generation is to be made cleaner, it must play a large part.\n\nThe International Energy Agency estimates that, if global greenhouse gas emissions are to be halved by 2050, as scientists say is necessary, then wind must represent about 17 per cent of worldwide power generation by that date.

"As offshore wind farms are being built farther from the coast and more offshore oil and gas installations are powered from shore, there will be an increasing need for long-distance underwater power transmission in the years to come."

"At a time when Iran's economy is tied up with sanctions, limiting its international trade capacities, it managed to sell more than a million vehicles (885,000 passenger vehicles and 128,000 light commercial vehicles) in 2012, enforce Euro IV norms in 8 cities including Tehran, Karaj, Arak, and Tabriz, convert all public cars into Compressed Natural Gas (CNG) compliant vehicles, and successfully implement a vehicle scrappage program to get very old, highly polluting vehicles off the streets of Iran. The prospect of such a country opening up to trade, giving an opportunity for global automotive companies to be a part of its growth, certainly creates buzz in the industry. Iran sold close to 860,000 passenger vehicles in 2014, 88% of which were sold by Iran Khodro Industrial Group (IKCO) and SAIPA under different marquees. With around 11.7 million vehicles on the road, the aftermarket potential is massive and the average age of vehicles is steadily increasing."

"A peer-reviewed life-cycle assessment (LCA) study shows a major decline in energy demand and greenhouse gas emissions for primary aluminum production in the U.S. and Canada. The study covers all life cycle impacts from aluminum production through semi-fabrication."

Last week the Spanish government announced plans to cut subsidies for solar photovoltaic (PV) power by about 75%. Although the nation expects to surpass its 2010 goal for installed solar by four fold, the down side is that generous subsidies for the industry have resulted in a ballooning tariff deficit for the country, which has risen to 4.85 billion euros, upfrom 745 million last year. Reuters reported that lending to the Spanish photovoltaic plants has risen to $3.59 billion in the year to day, up from $230.9 million euros last year and $192.44 million in 2006. As a result, the Spanish government will as the energy regulator to cap subsidies for new PV solar capacity at 300 megawatts (MW) per year--200 MW for rooftop systems and 100 MW for ground-mounted systems, which have been the highest growth area. CSP has been slower than PV technology in its emergence on the renewable energy scene, but expectations for the technology, which focuses the heat of the sun to produce steam to drive electricity producing turbines. Projects underway in the U.S. and Spain are expected to produce electricity that is cost-equivalent to electricity produced from burning coal or natural gas.
