I just recently presented an update on the solar market and global policies to UT. Enjoy!

1. Growth of Distributed Solar Power
Iga Hallberg -
Vice President Business Development

2. Energy Generation and the
Terawatt (TW) Challenge
• Humanity uses 12 TW of power today
– 1 TW = 1,000 GW (Gigawatts)
• World will need 15 TW by 2012
• Only 5 known sources of energy are available on a TW scale*
– Fossil fuels: Coal, oil, gas
– Nuclear fuels
– Solar
• Only inherently distributed solution
• No fuel cost

3. Sun – Our Free Fuel!
The earth receives more energy from the sun in just over one hour
than the world uses in an entire year

11. Growing Competitiveness of Solar

(1) kWh = kilowatt hour; kWp = kilowatt peak; TWh = terawatt hour; Wp = watt peak; the annual solar yield is the amount of electricity
generated by a south-facing 1 kW peak-rated module in 1 year, or the equivalent number of hours that the module operates at peak rating.
(2) Tier 4 and 5 are names of regulated forms of electricity generation and usage.
(3) Unsubsidized cost to end users of solar energy equals cost of conventional electricity.

12. In deregulated regions, fuel price
depends on the marginal fuel

Discussion
 Prices of the fuel type that sets the
marginal price of electricity most
impact electricity price
 Natural gas sets the price for
electricity in the Northeast, California,
and Texas
 This coincides with the regions with
the highest average electricity prices
and regions with deregulated markets
