Energy Q&A: how important is it?
• How much kerosene was burned to get  40 gallons per person in the
me from DC to t e S US ( 500 mile)?
e o C the SFUS (2500 e) plane

• How long does a luggage handler  5 to 8 hours, as he is likely to
have to load an unload bags before he use/produce between 125 Watt
has spent 1 kW of physical energy? and 200 Watt

• How many labor hours does a gallon  100 to 160 hours, or up to 4
of Kerosene represent if we assume a working weeks of physical labor
50% efficiency?
ffi i ?
• How many hours of energy “life  Every American has the
support” does the average American equivalent of 275 “employees”
get per year?
t ? continuously working for
him/her
• What is the average energy efficiency  < 2%
we reach in modern society?

Small Wind in California

Here we provide an overview of the
specific relevance of small wind in
California and how we can play a role..


Small Wind Potential

• AWEA (2010): the market for small wind energy applications will
continue to show robust growth for the next decade

• US market is largely being served by US companies (95% share)
a d t e bulk o t e $83M sales s being done
and the bu of the $83 in sa es is be g do e by less t a 10
ess than 0
suppliers

• Global small wind sales in 2009 were close to $200M

• Global small wind market held up very well during the economic
crises showing robust growth in 2008 and 2009

• Smaller projects are easy to finance locally and have very limited
stakeholder complexity


Small Wind Potential

Wind Resource is Key to Success in Wind,
Big
Bi or small
ll
• California has been leading US in
renewable energy portfolio standards,
programs and projects
• Wind resources are reasonable so you need
to be resourceful
• Small wind has BIG potential in urban
environment provided it is based at sites
with good wind resources
• And you start a program at good, clean
wind resource sites
• In SF at Treasure Island, Twin Peaks, etc
before taking over the town, wind-pocket
by wind-pocket..

Small Wind Opportunity San Francisco

• Although we are concerned with the Temporary Suspension of the
Emerging R
E bl Program, M h 4th 2011
i Renewables P March 2011..

• We represent an opportunity to land a new, innovative Cleantech
company in the area which will create high-level, green jobs,
high level,
launching a truly competitive product with strong local market
potential

• We i
W aim at a dominant position i th 1 5 kW segment generating
t d i t iti in the 1,5 t ti
$12.5M in revenues in 2014

• What would attract an initiative like this to come to the region:
• Local initiatives to support and cluster Cleantech companies and
academia
• State and local economic development, incentive and R&D
programs available to attract green technology ventures
• Positive climate for Cleantech venture capital funding

WIMBY, Wind In My Back Yard

• Turn opponents into supporters
• Activate all necessary stakeholders
• Link wind energy to sustainable
living
• Integrate success and “ownership”
into local education
plans
