Greening our grid through renewable energy purchases

Uploaded by googlegreen on 07.09.2011


Ever think about how much energy it takes to search for
something on Google?
Our engineers spend a lot of time thinking about it and
working hard to make our operations as
efficient as possible.
This means when you search on Google or use one of our other
products or services, you don't use much energy at all.
We've always optimized our data centers for efficiency,
designing them to sip rather than gulp energy.
For the energy we do need to power our products and
services, we are finding ways to use and
purchase clean energy.
One of the ways we buy clean power is through power
purchase agreements.
PPAs are contracts to buy energy from specific
facilities that supply energy to a regional power grip.
We engage in PPAs specifically for renewable energy sources
like wind farms.
Why not just build clean energy sources right on our
data centers?
The places with the best clean power potential are generally
not the same places where a data center can most
efficiently and reliably serve its users.
And while our data centers operate 24/7, most renewable
energy sources don't yet.
Google seeks out PPAs that lead to new renewable energy
sources being added to the grid over time.
With PPAs, we aim to encourage the creation of additional
So we enter into long-term, large scale contracts that
enable clean energy providers to get the financing they need
to build new projects.
At Google we have a strong interest in buying clean
energy now and ensuring that we all have clean reliable
sources of energy into the future.
It's our hope that purchases like these help support the
market and drive down the cost of clean power, enabling
renewable energy projects to multiply.
