Solar Suburbia to Power Modern Cities

In collaboration with the New Zealand Energy Centre and the University of Auckland, Byrd and his colleagues found that detached suburban houses typical of a motor car age city are capable of producing ten times more solar power than is possible from skyscrapers or other commercial buildings. The calculations are based on a detailed cross section of Auckland, which has skyscrapers in its business centre but has most of its homes spread out over the surrounding countryside in an urban sprawl. Byrds idea is that if planners insist solar panels be fitted to properties and charging points be provided for electric cars, then cities judged to be damaging to the environment could be transformed. While a compact city may be more efficient for internal combustion engine vehicles, a dispersed city is more efficient when distributed generation of electricity by photovoltaic installations is the main energy source and electric vehicles are the principal mode of transport says Byrd. This research could have implications on the policies of both urban form and energy. Far from reacting by looking to re-build our cities, we need to embrace the dispersed suburban areas and smart new technologies that will enable us to power our cities in a cost-effective way, without relying on ever dwindling supplies of fossil fuels. Sprawl is good This study challenges conventional thinking that suburbia is energy-inefficient, a belief that has become enshrined in architectural policy.

SolarCity whipsawed in solar-sector selloff

And thats probably reason enough for plenty of investors to use the companys quarterly report as an excuse to lock in some pretty hefty profits. But theres another factor motivating sellers. First Solar Inc. /quotes/zigman/102025 /quotes/nls/fslr FSLR reported its second-quarter results after the close Tuesday. It missed expectations by a mile, printing 39 cents a share vs. consensus of 56 cents. It also cut its full-year 2013 outlook.

Report Counts Up Solar Power Land Use Needs

Keeping up with the new solar policy, the state government issued a letter of intent to seven companies, Colonizers and Developers, Jackson Power Pvt Ltd, DK Infracon Pvt Ltd, Rifex Energy Pct Ltd, Essel Infra Project, Azure Surya Pvt Ltd and Moserbaer Clean Energy Ltd. This would enable them to set up solar power plants with a total installed capacity of 130 MW in the Bundelkhand region. Akhilesh govt looks to solar energy to bridge power shortfall Chief Minister Akhilesh Yadav said his government was committed to ensuring maximum power supply to the state through different resources. The state government had come up with a new solar energy policy earlier this year. The government has also signed a memorandum of understanding (MoU) for acquiring around 424 MW of power for the next 25 years from the year 2016 by Lanco Power Limited. This is the second such agreement in the last one month. Government officials said these initiatives were part of efforts of the state government to bridge the yawning gap between demand and supply of electricity in the state.

Solar benefits set to dim

Early birds locked in the best rebates that were designed to fade as equipment prices dropped. In San Diego and southern Orange counties, rebates for residential solar installations already have been exhausted as a result of the programs popularity, though a short extension is still possible. Rebates for small, nonresidential arrays and solar hot water heaters are still available. The payback for installing solar is now shifting to other state provisions, along with a federal solar tax break. 700 to 800 Rooftop solar arrays that are being installed each month in San Diego Gas & Electric territory 26,000 Approximate number of SDG&E customers that now generate their own solar power No-money-down lease agreements, which wrap in incentives, have democratized rooftop solar energy systems that otherwise can cost tens of thousands of dollars upfront. Rooftop solar installers, meanwhile, have seized upon a major utility rate hike to drum up business. Bill increases take effect Sept. 1 for San Diego and southern Orange counties. State rules help Sullivan Solar, a top contractor for solar installations in San Diego County, had its biggest sales month ever in July, while advertising solar panels as energy independence against utility rate increases. Daniel Sullivan, president of the company, said the sectors success is underwritten chiefly by state rules for billing customers. Those regulations effectively double kilowatt-hour rates for households using the most energy over the least intensive customers.

Pak envoy does a U-turn on Dawood, India seeks action in 1993 Bombay blast case

Census Bureau , there are around 115 million occupied and fully used homes in the country. If we just scale up linearly (which is not, of course, how this would actually work), that means 3.68 million acres to power all of them. That’s equivalent to 5 750 square miles, or around 0.1 percent of all the land the US has to offer. Not bad! Perhaps more relevant is the question of how these land use requirements measure up to other forms of energy. When it comes to renewables, there’s no doubt that solar power is far more area-efficient than wind power; an NREL report [PDF] from several years ago found a total requirement of about 84 acres per MW, a far cry from the 10 or so acres that solar seems to max out at. Geothermal energy might be the best of the bunch, though, in the low single digits. Outside of renewables, things can get a bit complicated.
