Google announced its new green project addressing climate change - RechargeIT. In an effort to decrease the effects of climate change through reducing the effects of oil such as CO2 emmissions, improving energy efficiency and supporting clean energy sources, RechargeIT will attempt to increase the world’s adoption of plug-in hybrid cars and vehicle to grid applications. Google chose plug-in hybrid cars because..

Transportation related greenhouse gas emissions are responsible for roughly one third of greenhouse gas emissions in the United States and at least 20% globally. In the US, over 60% of the transportation emissions result from gasoline consumption for personal vehicle use. We believe that plug-in hybrids capable of running on biofuels are the best near term option for significantly reducing greenhouse gas emissions from the transportation sector.

Plug-in hybrid vehicles can achieve 70 -100 miles per gallon, quadrupling the fuel economy of the average car on the road today (~20 mpg), and doubling the fuel economy of a regular hybrid car such as a Prius (~45 MPG). A plug-in hybrid is different from today’s hybrid because it has a higher capacity battery and the car can be plugged into a regular 120-volt outlet for charging. Because it is operating primarily on electricity for the first 20-40 miles, the car operates much more efficiently and uses dramatically less gasoline. Manufacturers are now designing plug-in hybrids that may not use any gasoline at all for those first 20-40 miles, and since more than 70% of Americans drive less than 33 miles per day, many will not use any gasoline in their daily commutes — but they retain the flexibility of using the hybrid gas engine for longer trips. In addition, plug-in hybrids will often recharge at night using excess power from base-load power plants that are already running, so they won’t generally add to peak electricity demand. During daytime peak power usage, plug-in hybrids may be able to sell power back to electric utilities, potentially earning drivers as much as $2,000-$3,000 per year

This Google.org project will include the demonstration of the technology to show to the public how these plug-in hybrids fare compared with non-plug-in cars in terms of environment-friendliness. To further support this cause, Google will also be doing public engagements, providing grants and investing on others that are doing similar green projects.
