Energy Q&A: how important is it?

• How much kerosene was burned to get me from DC to the SFUS (2500 mile)?

Energy Q&A: how important is it?

40 gallons per person in the planee o C to t e S US ( 500 e) plane

• How long does a luggage handler have to load an unload bags before he has spent 1 kW of physical energy?

5 to 8 hours, as he is likely to use/produce between 125 Watt and 200 Watthas spent 1 kW of physical energy? and 200 Watt

• How many labor hours does a gallon of Kerosene represent if we assume a 50% ffi i ?

100 to 160 hours, or up to 4 working weeks of physical labor

50% efficiency?

• How many hours of energy “life support” does the average American

t ?

Every American has the equivalent of 275 “employees”

get per year? continuously working for him/her

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 decadecontinue to show robust growth for the next decade

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

• 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


Source: AWEA Small Wind Turbine Global Market Study 2010

Wind Resource is Key to Success in Wind,Bi llBig or small

• 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..
