(InfoWorld) - Google on Monday turned on the solar panels covering nearly all the roof space on its corporate campus and announced that its philanthropic arm plans to dole out over $10 million in grants to support hybrid cars. The announcements follow one last week made from Google's offices in Mountain View, California that launched an industry-wide initiative around improving the energy efficiency of PCs and servers. The solar panels, which make up the largest solar installation on a corporate campus in the U.S., produce 1.6 megawatts of energy, enough to supply about one-third of Google's energy use on the campus, said Jacquelline Fuller, a Google spokeswoman. In addition to the solar panels, Google has also unveiled a new employee parking garage where drivers can charge their plug-in cars, powering up their batteries using solar energy. Plug-ins are hybrid cars that users can drive in all-electric mode for around 30 miles before relying on the gas engine. Because automobile manufacturers aren't producing plug-ins, Google is converting hybrid cars into plug-ins. So far, it has converted four Toyota Prius and two Ford Escapes, Fuller said. On its RechargeIT Web site, Google is posting data on the performance of the cars. Eventually, the company plans to have 100 such plug-in cars that employees who take public transportation to the office will be able to use to run errands during their work days as part of a car-sharing program. The announcements about the changes to the corporate campus were part of the launch of the RechargeIT Initiative by Google.org, the philanthropic arm of the company, on Monday. The plan includes several efforts mainly around plug-in cars, starting with grants already dispersed to a variety of groups. Google.org has given $200,000 each to the Brookings Institute in support of a conference next year about federal policy to promote plug-in vehicles and CalCars for the continuation of its educational initiatives about the cars. The Electrical Power Research Institute, Plug-In America, Rocky Mountain Institute, and a professor at the University of Delaware all have also received grants for their plug-in car projects. In addition, Google.org has earmarked $10 million for investments in companies and projects that support alternative transportation that reduces the use of fossil fuels and emissions. Later this summer the company plans to formally request proposals for the grant money. Last week, Google hinted at the impending launch of environmental initiatives when it hosted the introduction of theÂ Climate Savers Computing Initiative. That group, which includes a who's-who list of the technology industry such as Intel, Dell, Sun Microsystems, Microsoft, and Hewlett-Packard, is setting a series of standards that will incrementally improve the efficiency of power cords used on PCs and servers through 2010.

(InfoWorld) - San Francisco city officials could bring the city'sÂ proposed Wi-Fi networkÂ closer to reality at two meetings this week as a key leader proposes significant changes to the plan. The network, to be run by EarthLink, has been closely watched because it is one of the biggest of many proposed municipal networks in the U.S. and because it would include a free service offered by Google. The city would sell EarthLink access to some of its streetlight poles and other locations for Wi-Fi access points. Some leaders and activists in the famously liberal city haveÂ slammed the dealÂ on issues including privacy and service and called for a network owned by the city. On Tuesday, the Board of Supervisors will reconsider an April decision by the city's Planning Department to exempt the network from an environmental review. The San Francisco Neighborhood Antenna-Free Union (SNAFU) appealed the April ruling, saying the access points could cause health problems. The board could let the Planning Department's decision stand, strike it down or decide to study the issue further. On Wednesday, the Board's Budget and Finance committee will vote on the full Wi-Fi proposal. Unless the vote Tuesday requires an environmental review, the only remaining hurdle then would be a vote by the full board. The Budget and Finance panel will hear proposals by board President Aaron Peskin that may boost support for the politically troubled plan. Both the mayor's office and EarthLink are aware of the proposals, Peskin said in an e-mail interview. The mayor's office seems to approve of them, but Peskin doesn't know where EarthLink stands. Peskin's ideas affect aspects of the proposed contract that have drawn much of the fire. Key points include: - Increase the speed of the free service from 300Kbps to 500Kbps. (A service priced at about $20 per month would still deliver 1Mbps.) - Provide for user privacy on the free service. - Add an enforceable requirement that the network provide adequate service in all areas of the city. - Shorten the maximum term of the contract from 16 to eight years and let the city buy the network at full market value at that time. As it stands, the contract initially would be for four years and could be renewed three times, an eternity in the world of wireless technology. - Ensure the city is properly compensated for giving EarthLink access to its light poles. The city and EarthLink settled on the terms of a contract in January. It gave EarthLink the right to pull out if the plan wasn't approved by the Board within 180 days. That time has passed, according to EarthLink spokesman Jerry Grasso, but the company hasn't given up. The plan calls for building a two-square mile test network first before deploying the whole system. Â

(InfoWorld) - The sun came out for EarthLink's Philadelphia Wi-Fi network on Thursday even as prospects forÂ its San Francisco projectÂ remain shrouded in fog. Wireless Philadelphia, a nonprofit group formed by the city of Philadelphia, has approved the 15-square-mile Wi-Fi test network EarthLink built, opening the door for the operator to finish building out a 135-square-mile network covering the city. The approval comes just a month afterÂ EarthLink announced it would scale back its city Wi-Fi initiative, focusing on existing and large cities for the rest of the year. The company has seven or eight cities under contract now and is negotiating with five more, Vice President of Product Strategy and Marketing Cole Reinwand said last week. It decided to stagger its Wi-Fi expansion to conserve resources, he said. Residents can already use the 15-square-mile network in Philadelphia. The full network is expected to be complete in the third quarter. EarthLink is financing, building, and managing the network and will share revenue with Wireless Philadelphia, which will offer cut-rate access for low-income people. For six months, customers of a 1MbpsÂ service will pay an introductory rate of $6.95 per month, which bumps up to $19.95 thereafter. A faster 3Mbps service is available for $9.95 for the first six months and $21.95 after that. City parks will have free access, and low-income residents can sign up for service at $9.95 per month, before promotions. Customers can also pay for service on an hourly, daily or three-day basis. The Philadelphia Wi-Fi network is notable because when announced, it set off a storm of controversy that resulted in a Pennsylvania law requiring municipalities to receive approval from incumbent telecommunications operators before building Wi-Fi networks. The law was created after incumbents complained that by financing Wi-Fi networks, cities were building networks that would compete with their businesses. The San Francisco project, which has drawn attention partly because of Google's planned involvement as provider of a free citywide service, has run into fierce opposition from activists as well as some local elected officials. The proposed contract is scheduled for a vote by the city and county's board of supervisors in July.
