I've harped on about Google a fair bit over the years - but i do like some of the stuff google.org is doing on climate change
It’s All About Reversing Global Warming
The climate crisis requires a radical reduction of greenhouse gases to minimize the impact on human health and the environment. Greenhouse gas emissions from energy use are responsible for over two-thirds of global emissions, therefore curbing this threat will require a major transformation in how we make and use energy – for transportation and for electricity.
What is RechargeIT doing?
RechargeIT is an initiative within Google.org's Climate Change Program aimed at accelerating the adoption of plug-in hybrid electric vehicles ("plug-in hybrids") and vehicle-to-grid ("V2G") applications. As a "hybrid" philanthropic venture itself, Google.org can apply a broad mix of resources - investments, grants, policy, public engagement - to addressing the climate crisis. Check out the highlights:
Plug-in Hybrid Demonstration Fleet at Google: Google has created a small demonstration fleet of plug-in hybrids and eventually plans to include over 100 plug-in hybrids in its corporate fleet as demand grows and cars become commercially available. Google.org has contracted with Hymotion to retrofit 4 Toyota Priuses and 2 Ford Escapes. Google.org is demonstrating the capabilities of this technology, collecting actual data on the performance of these vehicles, and making this information available to the public. All of these cars are outfitted with data recording devices that track technical and environmental performance, use patterns and charging history. You can see the actual data which is uploaded from the vehicles. Both electricity and gasoline use data is being used to calculate the total energy use for each vehicle to get 'real world' performance data on these cars. In order to compare this data to other cars under similar conditions, we are equipping existing stock hybrids and conventional cars with the same data recording devices. With this data, we hope to be able to measure the mileage of plug-in hybrids vs. conventional gas and hybrid vehicles under realistic driving conditions. To date, our plug-in hybrids are averaging about 75 miles per gallon of gasoline which is four times that of the average car on the road in the US today.
Solar Charging at Google: We will be connecting the Google fleet of cars to solar charging stations on campus to demonstrate the role that renewable electricity can play in replacing gasoline and other fossil fuels in the transportation sector. Learn more about the solar panels at Google.
V2G Demonstration at Google with PG&E: RechargeIT is also exploring ways to develop and deploy V2G technology. With the help of PG&E, Google will be demonstrating how electricity might be transmitted back and forth between plug-in hybrids and the grid. V2G offers the potential to use plug-in hybrids as a battery storage to make better use of our energy and stabilize the grid. Similar to the plug-in hybrid vehicle demonstration, the objective is to collect real world data to understand the benefits of V2G and enable future adoption.
Strategic Grant-Making and Investments: Later this summer Google.org will publish a formal request for proposals (RFP) on our website, focused on investment opportunities in companies and projects accelerating the commercialization of alternative transportation that reduces vehicle fossil fuel use and climate emissions. We are looking to invest approximately $10 million in technologies and companies featuring plug-in hybrids, fully electric vehicles, vehicle-to-grid capabilities, batteries and other storage technologies, and the application of renewable energy and fuels to green vehicles. We believe that our investments in green vehicle technology commercialization, coupled with additional R&D and policy grants, will help accelerate progress in addressing the climate and energy challenges of today's transportation sector. To date, Google.org has already made $1 million worth of grants to support several outstanding organizations. Read more about our grantees.
Google Fleet: To encourage alternate forms of commuting, Google will offer a free car-sharing program to its employees at its Mountain View, CA headquarters. This program will provide employees who come to work by carpooling, taking public transport, riding the Google shuttle, or self-powered commuting (bicycling, walking, etc.) with the ability to use a car during the day. This corporate car-sharing program enables employees who need to go to business meetings or run errands to avoid driving to work in a single occupant vehicle. This program is based on a partnership with Enterprise Rent-A-Car who will manage the fleet.
Why Plug-in Hybrids?
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 (see http://www.udel.edu/V2G/).
People often ask whether this won’t just shift pollution from cars to power plants, but even without adding any new power plants, the existing U.S. electrical grid has sufficient capacity to fully fuel three quarters of the nation’s 217 million passenger vehicles, assuming the average car drives 33 miles per day. This integration of hybrid cars with the electric power grid could reduce gasoline consumption by 85 billion gallons per year. That’s equal to a 27% reduction in total U.S. greenhouse gases, 52% displacement potential of U.S. oil imports, and $270 billion avoided in gasoline expenses (see http://www.pnl.gov/energy/eed/etd/pdfs/phev_feasibility_analysis_combined.pdf).
Broader Energy Management - Vehicle-to-Grid Transmission
Increasingly, there are ways for each of us and for corporations to generate electricity through renewable resources and store electricity that can be sold to a power company. There is significant potential for plug-in hybrids to also become power suppliers. This vehicle-to-grid ("V2G") approach may be particularly attractive when there are peaks in power consumption that a utility may not be able to handle through normal power generation. When utility demand exceeds normal generation capacity, the utilities resort to stand-by power generating sources (which often cause higher levels of emissions) and in extreme cases instituting rolling brownouts. At significant scale, plug-in hybrid batteries could help deliver power during peak times when it is often the most expensive. This could generate revenue for the car owner and help the utilities deal with peak demand.

A clean energy update from Google
Today Google.org is launching an exciting project that offers a glimpse of a smarter energy future: cars that plug into an electric grid powered by solar energy. Plug-in hybrid electric vehicles (“plug-in hybrids”) can achieve 70 -100 miles per gallon, quadrupling the fuel economy of the average car on the road today (~20 mpg). As we demonstrated at today’s event, plug-in hybrids can sell power back to the electric grid when it's needed most through vehicle-to-grid (V2G) technology
As you may know, one of Google.org's core missions is to address climate change. In the U.S., transportation contributes about one-third of all greenhouse gas emissions –- with more than 60 percent of those emissions coming from personal vehicles. By accelerating the adoption of plug-in hybrids and vehicle-to-grid ("V2G") technologies, this new project, RechargeIT.org, aims to reduce emissions and dependence on oil while promoting clean energy technologies and increasing consumer choice. Linking the U.S. transportation system to the electricity grid maximizes the efficiency of our energy system. From these efforts, we believe the environment will benefit -- and consumers will have more choices to fuel their cars.
We've been working with Google engineers and Hymotion/A123Systems to build a small fleet of plug-in hybrids, adding an external plug and additional batteries to a regular hybrid car so that it runs on electricity with gasoline (or even better, biofuels) to extend the driving range for longer trips. Here's what it looks like:

Since most Americans drive less than 35 miles per day, you easily could drive mostly on electricity with the gas tank as a "safety net." Our goal is to demonstrate the plug-in hybrid and V2G technology, get people excited about having their own plug-in hybrid, and encourage car companies to start building them soon.
In the preliminary results from our test fleet, on average the plug-in hybrid gas mileage was 30+ mpg higher than that of the regular hybrids. In conjunction with Pacific Gas and Electric, we also demonstrated the bidirectional flow of electricity through V2G technology, and have awarded $1 million in grants and announced plans for a $10 million request for proposals (RFP) to fund development, adoption and commercialization of plug-ins, fully electric cars and related vehicle-to-grid (V2G) technology. (Here's the full release.)
As for Google Inc., today the solar panel installation we announced last October is now producing clean, renewable electricity for our Mountain View, CA headquarters.

The system will offset peak electricity consumption at the solar powered offices and the newly constructed solar carports have charging stations for the plug-in hybrids. At 1.6 megawatts -- with an electricity output capable of powering approximately 1,000 average California homes -- the Google project is the largest solar installation on any corporate campus in the U.S. to date, and one of the largest on any corporate site in the world. To see how much electricity these panels are producing right now, visit our new performance monitoring site.
To learn more about the initiative, we encourage you to explore the rest of RechargeIT.org.
