The project, tagged as one of the largest foreign direct investment (FDI) into the state, will also be a landmark project as the cost of power generation is likely to be 70 per cent less — around Rs 20,000 crore — than the conventional cost of generation, say sources close to the development.
The project envisages an integrated solar city wherein all the raw materials including glass and panels will be produced by them, bringing down the cost substantially, said a senior government official.
The cost of generation for thermal energy is about Rs 10-11 per unit. However, according to estimates of Clinton Foundation, the power produced in the solar city will cost around Rs 4 per unit, going by the scale of the project and technology advancement they have on hand.

An international team led by Physics and Chemistry teams from the Faculty of Science and Technology at the University of the Basque Country (UPV/EHU) and directed by Professor Jose Javier Saiz Garitaonandia, has achieved, by means of a controlled chemical process, that atoms of gold, silver and copper - intrinsically non-magnetic (not attracted to a magnet) - become magnetic. The article has been published in the February issue of the prestigious international magazine in nanotechnology, Nanoletters (Vol.8, No. 2, 661-667 (2008).
New EU renewables law takes shape | EU - European Information on Energy - 0 views
-
While the draft directive , made available by Friends of the Earth Europe (FoEE), does not specify the precise percentage figures by which each member state will be required to increase its share of renewable energies, the following criteria are put forward: By 2014, each member state's share of renewables must be at least the amount it used in 2005 plus 51% of the 2020 target; by 2016, the figure must increase to 66% of the 2020 target; and; by 2018, member states should have achieved 83% of their 2020 target (compared to the 2005 level as usual).

The Oil Drum | Alternative Wind Power Experiments - SkySails and Airborne Wind Turbines - 0 views
-
Wind power is currently the fastest growing renewable energy source (in terms of capacity - solar has a faster percentage growth rate), and looks like remaining so into the next decade. While most attention is focussed on the mainstream approach of generating power using large wind turbines - both onshore and, as Jerome recently looked at, offshore - there are a wide range of alternatives being considered for harvesting energy from the winds. In this post I'll look at 2 approaches that have received some attention in the press recently - attaching kite sails to ships and airborne wind turbines

To be explored after we've fully exploited energy efficiency's potential, and all the onshore and offshore technologies we can think off. But the market will take care of this automatically, unless the EU comes up with the idea of a kite directive ...
Cleantech Blog: Smart Grids and Electric Vehicles - 0 views

In the future, utilities will pay you to plug-in your vehicle. Millions will plug-in their electric vehicles (EV), plug-in hybrids (PHEV) and fuel cell vehicles (FCV) at night when electricity is cheap, then plug-in during the day when energy is expensive and sell those extra electrons at a profit. Vehicle to Grid (V2G) technology is a bi-directional electric grid interface that allows a plug-in to take energy from the grid or put it back on the grid.

Well ... time will tell whether plug-in hybrids will be a "licence to print money scheme" or a technology to balance the grid. Because there is a reason for the peak - we all use energy according to the same pattern, driven by day-night, office hours and schools.

HTS Linear Generators Slated for PowerBuoy Wave Energy Converters - 0 views
-
Ocean Power Technologies, Inc (OPT) and Converteam Ltd. recently signed a Cooperation Agreement for the development of High Temperature Superconductor (HTS) Linear Generators for use in OPT's PowerBuoy wave energy converters. "HTS is a truly disruptive technology the advantages of which will radically change wave energy capture. Converteam is looking forward to working with OPT on this exciting and challenging new project." -- Derek Grieve, Technology Director, Converteam Ltd. The vision of the two companies is the direct conversion of the linear up and down motion of waves into electricity using OPT's PowerBuoy and Converteam's HTS linear generator. The proposed power take-off for the OPT PowerBuoy will employ Converteam's innovative and proprietary linear generator system with high temperature superconductors to provide the magnetic field.

Two new solar communities with 20 homes combined are due to be completed in Gilroy, California by the end of the year each outfitted with a BP Solar solar electric system. "We all need to do our part to meet the California Solar Initiative, and this is definitely a step in the right direction. I'm glad to see the residents of Gilroy have solar available in the most economic way, which is having it installed during construction, rather than later as an add-on." Al Pinheiro, Mayor of Gilroy

Geoengineering could dim lights on solar power - environment - 23 April 2009 - New Scientist - 0 views
-
PUMPING aerosol particles into the atmosphere to create a sunshade could take a heavier toll on solar power generation than expected. For every 1 per cent of the sun's rays deflected into space, the average output of solar systems that rely on direct sunlight would drop by 4 to 5 per cent, says Daniel Murphy at the US National Oceanic and Atmospheric Administration in Boulder, Colorado. Geoengineers propose scattering 1 to 2 per cent of sunlight.
Rethinking wind power - 3 views

Over time, what resulted from these assessments was that we selected the following sources to provide commercial electricity: hydroelectric, coal, nuclear, natural gas, and oil. (Oil is by far the smallest source.) Note that each of these current sources meet ALL of the above six essential criteria — and if they don’t (like oil recently becoming more expensive), then they get replaced, by other conventional sources that do. As a result, today, and a hundred years from now, these sources can provide ALL of the electrical needs of our society — and continue to meet all six criteria. So what’s the problem? A new criteria has been recently added to the list of criteria: environmental impact — and the current number one environmental impact consideration is greenhouse gas emissions (e.g. CO2). So why has this joined the Big Six? It is a direct result of the current debate on global warming. In response to intense political pressure, governments have acquiesced to these forces to make emissions an additional criterion. Having government step in and mandate that utility companies change the principles that have been the foundation of our electrical supply system for a hundred years is disconcerting, transforming such a successful system based on a position that is not yet scientifically resolved. Furthermore, this new criteria for electrical supply sources now has taken priority over all the other six. It has, as of late, become the ONLY benchmark of importance — the other six have essentially been put aside, and are now given only lip service. In this unraveling of sensibility there is one final incredible insult to science: alternative sources of commercial electricity that claim to meet this new super-criteria (to make a consequential impact on CO2 reduction) don’t even have to prove that they actually do it! Let's look at the environmental poster child: wind power, and examine each of the six time-tested criteria, then the new one...
Want fewer power plants? Make outdoor lighting more efficient - 0 views
-
The proposed changes will phase out the least efficient outdoor lighting products by the end of 2012, transitioning to new lighting products that are better for the environment and less costly to run. For example, new outdoor lights will be required to have a sensor that will turn them off during daylight hours, putting an end to wasteful streetlight operation during the day. New parking lot lights must be capable of being dimmed, which can cut their energy use in half. The agreement also directs the US Department of Energy (DOE) to develop even better standards by 2013.
