by purchasing
renewable
energy credits (recs)
from keechi,
microsoft can

reduce its carbon
footprint

keechi is on the same power grid
as microsoft's san antonio data center

the data center is powered
by the local grid

by supporting a
green grid in texas
microsoft is making a
direct investment in

renewable energy

cloud
computing

the investment meets the
principle of additionality
by bringing new
renewable energy
on to the texas electric grid.

how microsoft is buying green energy

A business division
usescarbon-based
energy or air travel

The carbon fee is paid by the
division based on amount of
carbon emissions

That money goes into
Microsoft's carbon fund

Microsoft invests the carbon fund
in projects to reduce our footprint

renewable energy
Wind, solar and biogas

energy efficiency
Projects across global facilities

high-quality carbon offsets
Renewable, low-carbon
development and reforestation

but wind is hardly the beginning

50% of energy
generated

from hydroelectricity

primary energy source
in data center (83%) is
hydroelectricity

us epa
award

for purchasing
1.9 billion
kilowatt hours of
green power annually

solar power system
offsets as much as

15%
of energy needs

microsoft is building its first zero carbon
data plant.it will be

powered
by fuel cells
that will operate
from energy generated

by biogas from

a nearby


water
treatment
plant

our new data center design goals:

30 to 50% more efficient, average

1.125 pue(power usage effectiveness)
