Donald Sadoway: The missing link to renewable energy | Video on TED.com - 0 views

  • Donald Sadoway: The missing link to renewable energy
  • What's the key to using alternative energy, like solar and wind? Storage -- so we can have power on tap even when the sun's not out and the wind's not blowing. In this accessible, inspiring talk, Donald Sadoway takes to the blackboard to show us the future of large-scale batteries that store renewable energy. As he says: "We need to think about the problem differently. We need to think big. We need to think cheap." Donald S

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

ArcelorMittal Launches Cleantech and Carbon Funds - 0 views

  •  
    ArcelorMittal (NYSE: MT), a steel manufacturer based in New Deli, launched a clean technology venture capital fund to support ventures that have relevance for the carbon-intensive steel industry. The Fund has made its first investment of US$20 million in Miasolé, a California-based pioneer in the development of thin-film solar panels Miasolé has developed unique high volume manufacturing processes that enable efficient production of Copper Indium Gallium Selenium (CIGS) solar products on a flexible stainless steel substrate. This technology promises to dramatically lowers the installed cost of Photovoltaic (PV) systems and will enable renewable energy from the sun to replace carbon generating fossil fuels. Fund managers will be working with leading venture capital firms, including Bessemer Venture Partners, Khosla Ventures, and Kleiner Perkins Caufield & Byers, to identify worthy cleantech ventures. ArcelorMittal also announced that it has created a new carbon fund in order to strategically engage in the carbon market and promote climate friendly solutions that are relevant for the steel industry. The fund, which has an initial investment commitment of €100 million (US$ 157 million) is currently looking at investment opportunities in renewable energy, energy efficiency, methane capture and greenhouse gas reducing technologies--all of which have the potential to generate carbon credits under the Kyoto Protocol. ArcelorMittal intends to use the carbon credits received from these Clean Development Mechanism and Joint Implementation projects for compliance in the EU Emissions Trading Scheme.

British Tidal Power System Connected to Grid - 0 views

  •  
    The world's first commercial-scale tidal power turbine has delivered electricity into the British grid for the first time in preparation for full-scale operation, Marine Current Turbines announced yesterday. "SeaGen is the world's first commercial-scale tidal stream generating system by a large margin. It is more than four times as powerful as the world's second most powerful tidal current system, which is our own 300kW SeaFlow, installed off Lynmouth on the north Devon coast more than five years ago." Secretary of State for Energy, John Hutton said: "This kind of world first technology and innovation is key to helping the UK reduce its dependency on fossil fuels and secure its future energy supplies" Marine Current Turbines' next project, announced in February 2008, is a joint initiative with npower renewables to take forward a 10.5MW project using several SeaGen devices off the coast of Anglesey, north Wales. It is hoped the tidal farm will be commissioned in 2011 or 2012. The company is also investigating the potential for tidal energy schemes in other parts of the UK, and in North America.

Ocean Power: Europe's Next Green Thing - 0 views

  •  
    Ireland's OpenHydro and Germany's RWE are spending millions to try to turn the power of waves into electricity With oil prices hitting almost daily record highs and global warming climbing up the public agenda, the need for alternative energy sources has never been more urgent. But while wind and solar have dominated the recent rush to invest in renewables, market watchers reckon it could now be marine energy's turn to shine. Ocean power-using the energy from waves or tidal flows to produce electricity-is quickly coming of age as a viable green resource that could help meet ambitious global targets to reduce greenhouse gases and dependency on fossil fuels. European and North American power companies such as Canada's Emera (EMA.TO) and Germany's RWE (RWEG.DE) are spending millions to fund wind and tidal projects. This investment has led to a new generation of more efficient technologies, with dozens of prototypes expected to be ready for commercial deployment within the next five years. "There's huge interest in both wave and tidal technology," says Thomas Boeckmann, clean tech analyst at market research firm StrategyEye in London. "It's gaining a lot of attention from energy companies, which will be able to offer financial backing and technical expertise to these startups."

Electron-democracy - 0 views

  •  
    The way electric power is generated and distributed will change substantially over the next two decades. Power will be democratized, as small-scale production at the individual and community level moves from niche to normal. The resulting "electron-democracy" will still have centralized power plants, but power grid activity will increasingly be dominated by innumerable incremental energy flows between small producers and consumers. This is likely to happen whether or not public policy mandates a shift away from dependence on fossil fuels.

Solar Water Heaters Now Mandatory In Hawaii | MetaEfficient - 0 views

  •  
    Hawaii has become the first state to require solar water heaters in new homes. The bill was signed into law by Governor Linda Lingle, a Republican. It requires the energy-saving systems in homes starting in 2010. It prohibits issuing building permits for single-family homes that do not have solar water heaters. Hawaii relies on imported fossil fuels more than any other state, with about 90 percent of its energy sources coming from foreign countries, according to state data.

Can renewable energy make a dent in fossil fuels? | Green Tech - CNET News.com - 0 views

  • 4.2 billion. That's how many rooftops you'd have to cover with solar panels to displace a cubic mile of oil (CMO), a measure of energy consumption, according to Ripudaman Malhotra, who oversees research on fossil fuels at SRI International. The electricity captured in those hypothetical solar panels in a year (2.1 kilowatts each) would roughly equal the energy in a CMO

Renewable energy means we need energy storage, too - 0 views

  • Storing excess renewable resources, such as solar and wind, is vital in securing an energy-efficient future. To understand just how vital energy storage is, consider this. Fossil fuel, such as coal and oil, are forms of stored energy, always ready when society needs it. Solar and wind are forms of “real” energy, coming and going irregularly. If we want to replace the value that fossil fuels afford our society, we have no choice but to add storage to intermittent renewable energy to make it readily available.

Trillions needed for World Energy Infrastructure Buildout to 2030 - 1 views

  •  
    "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."

A new Energy Policy for the new European Commission? - 0 views

  •  
    "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."

Total Worldwide Distributed Generation Capacity of Microgrids to More than Quintuple by... - 0 views

  • the total worldwide capacity of distributed generation (DG) contained in microgrids will more than quintuple over the next 6 years, growing from 764 megawatts (MW) in 2012 to nearly 4,000 MW in 2018. “Distributed generation assets are the foundation of any microgrid,” says senior research analyst Peter Asmus.  “Although the majority of DG today is in the form of fossil fuel-based systems, primarily diesel generators, recent growth rates confirm that the fastest-growing distributed power generation technologies are combined heat and power and solar photovoltaic systems, thanks to steep drops in prices for natural gas and solar PV panels.”
