Question l.jpg

Which global industry is larger?

  • Wind industry

  • Solar power industry

Answer: Both are about equal, but in 2006 solar is overtaking wind power. Worldwide, the wind industry installed more than $14 billion worth of new generating equipment in 2005, a 25% increase over 2004 according to figures released by the Global Wind Energy Council.

Question5 l.jpg

Which global industry is larger?

  • Internet search advertising (Google, Yahoo, etc..)

  • Solar power industry

Answer: Both are about equal

The worldwide solar industry reached $14 billion in 2005. Internet advertising revenues surpassed 12.5 billion in 2005.

Source: According to an estimate from the Interactive Advertising Bureau (IAB) and PricewaterhouseCoopers (PwC) and solar industry figures from the Solar Energy Industries Association.

Question6 l.jpg

What is the average annual growth rate of the solar industry over the past ten years?

  • 17%

  • 27%

  • 37%

  • 47%

  • Answer: C, The average growth rate has been 37%. In 2004-05 the growth rate was 47%.

Washington state s approach l.jpg
Washington State’s Approach

  • Production incentives

    • Payments to solar power producers based on measured output

    • Used by Germany with enormous success

  • NOT rebates

    • Rebates are based on cost of system, not how well the system performs

    • Rebates are popular in US, but not in Europe

Washington production incentive l.jpg
Washington Production Incentive

  • Unanimously approved by legislature in 2005

  • Utility pays a premium to customers that generate solar energy.

  • $0.15 per kWh for solar energy generated using equip. manufactured outside of Washington.

  • $0.54 per kWh for solar energy generated using equip. manufactured in Washington.

  • No Washington module manufacturer yet, but three scheduled for 2007.

  • Utilities get a credit for this payment on their utility-use tax.

Other washington solar policies l.jpg
Other Washington Solar Policies

  • Sales tax exemption for solar power equipment through 2011

  • Reduction in state B&O taxes for solar module manufacturers

What more can washington do to promote the solar industry l.jpg
What more can Washington do to promote the solar industry?

  • Establish incentives for commercial facilities

  • Facilitate large-scale generation

  • Create incentives for expanding silicon manufacturing along with wafer and cell production

Slide13 l.jpg

Oil has been the fuel of choice, but look what’s on the horizon?

What is a phev phev plug in hybrid electric vehicle l.jpg
What is a PHEV?(PHEV = Plug-In Hybrid Electric Vehicle)




Question17 l.jpg

How large of a solar array would it take to provide 90% of a PHEV’s total energy to drive 15,000 miles per year.

  • Cover the surface of vehicle

  • Cover the roof of the garage

  • ½ acre of land

  • 10 acres of land

  • Answer: B It only takes 350 square feet of solar

  • electric modules to provide the annual electricity

  • consumed by a plug-in hybrid electric vehicle.
