3. Normative Criteria
1. Optimizing the delivery of efficient energy services at or near the point of
use as the key goal, rather than simply expanding ever-larger resource
supplies shipped over ever-longer distances at ever-higher expense;
2. Environmentally and ecologically friendly and avoiding adverse impacts
(to terrestrial, freshwater, marine ecosystems);
3. Economically attractive now, with massive growth opportunity in the
foreseeable future (speed facilitated by well-crafted incentives, R&D,
policies and regulations);
4. Low-risk, risk-resistant and risk-manageable — against inflation, price
spikes, sudden disruptions, acts of nature or malicious attack;
5. Resilient — if the energy system (water, transport) fails, it fails gracefully,
not catastrophically, and is rapidly recoverable;
6. Enhancing climate, air and water quality;
7. Resulting in minimal adverse impacts and capable of further reducing
those externalities through continuous innovation and best practices; and
8. Robust experience curves — potential for significant, ongoing
improvements in cost, performance, reduced footprint, generation of
positive externalities, etc., through ongoing R&D and cumulative learning
experiences.

12. NUCLEAR
POWER?
The fascination with nuclear power is due to the fact
that 1 ton of uranium can displace 20,000 tons of coal
13. Unfortunately, uranium-generated electricity carries
some intrinsic downsides that are inherently
intractable:
1) Ever-present target of nuclear facilities for
military or terrorist attack;
2) Dual civilian-military nature of a nuclear
reactor;
3) Proliferation of weapons-grade material;
4) Diversion of uranium fuel for military or
terrorist use in fabricating atomic bombs;
5) Contaminant fuel wastes that remain
radioactive for millennia; and,
6) Generating systems that can fail
catastrophically, with disastrous human
health and ecological consequences lasting for
generations, and economic impacts lasting for
centuries
Displacing coal use worldwide by 2100 would require constructing a 100 MW
nuclear reactor every 10 hours for the entire century. It would require
reprocessing weapons-grade plutonium for use in breeder reactors by 2050.
This would produce 5 million kilograms of plutonium per year, equal to 500,000
atomic bombs, annually circulating in global commerce.
14. In the USA, cities and residences cover 140 million acres.
Every kWh of current U.S. energy requirements can be met
simply by applying PV to 7% of this area—on roofs, parking
lots, along highway walls, on sides of buildings, and in other
dual-use scenarios.
We wouldn’t have to appropriate a single acre of new land to
make PV our primary energy source!

20. Wind Power Advanced Scenario
INVESTMENT: By 2030, annual investment value of the
wind energy market would be $110 billion.
GENERATION COSTS: By 2020, a good site would be 4 to
5 ¢/kWh, and a low average wind site 5 to 7.7 ¢/kWh.
EMPLOYMENT: By 2030, 1.4 million jobs, and 2.8 million
by 2050.
CO2 SAVINGS: By 2030, 3.1 billion tons per year,
increasing to 4.7 billion tons per year by 2050. [Total CO2 in
2006 ~8 billion tons]

21. CHINA Advanced Wind Scenario
In 2005 China reset 2020 wind target to 30 GW. An increase of 10 GW from
the goal of just a year earlier. Raises annual growth rate from 20% to 24%.
Wind industry experts are confident that 170 GW is achievable by 2020,
and 330 GW by 2030. The required 39% annual growth rate is feasible,
they argue, IF utility pricing policies can be reformed.
22. CHINA Advanced Wind Scenario
NREL wind mapping of vast areas of eastern China at 50-m height found 4% of
the mapped LAND area could support 580 GW at a conservatively estimated 5
MW/km2(good-to-excellent wind resources).
NREL estimates windy MARINE sections could support >660 GW, and 4X this
figure Including moderate wind resources.
More studies are required to accurately assess the wind potential, considering
shipping lanes, water depth, existing transmission grid and accessibility.
23. Brazil Advanced Wind Potential
Rio Grande do Sul
Simulations, performed in 1999 by CEPEL (Brazil’s Electric Energy Research
Center), estimate a Brazilian wind potential of 144 GW.
This assumes average wind velocities of more than 7m/s, only on-shore, using
wind turbines of 600 kW. The Brazilian Center of Wind Energy (CBEE)
indicates wind power generation is between 4 and 8.4 ¢/kWh.
Yet, only 28 MW installed by 2005, and 200 MW by 2006.

24. Brazil Advanced Wind Potential
Along the 630 km coastline of
Rio Grande do Sul there are
986 km2 of sand and dunes,
fanned by intense and constant
winds.

Also inland, many winds come
together with the Minuano to
create one of the most
promising sources of wind
power in Brazil.

available for areas with winds summer spring

25. Rio Grande do Sul Wind Potential
The 55-115 GW of estimated wind power for Rio Grande do Sul is relatively
high. The total Brazilian hydro resources (inventoried plus estimated) is 143
GW, and Brazil’s total installed capacity was 77 GW in 2001.

28. Of the practically exploitable U.S. wind resources of moderate or better
quality, 95% are located in the sparsely populated 12 Great Plains states,
where the generation potential is 3X total U.S. electricity generation.

3. Conditionally favorable –
Conservation or open space lands
rated quot;low conflict,quot; or open space or

4. Most favorable – Unrestricted private

Although agriculture controls about 70% of the land area in all three sub-regions of the Great Plains
(Northern Great Plains = Montana, North Dakota, South Dakota; Central Great Plains = Wyoming,
Nebraska, Colorado, Kansas; Southern Great Plains = Oklahoma, New Mexico, and Texas), the
contribution of agriculture to the Gross Regional Product in very small. Agriculture is very
important in the region for many reasons, but it is not a major player in the regional economy
compared to other industries. (Source: U.S. Bureau of Economic Analysis 1998, USDA 1997 Census of Agriculture)

33. Potential Synergisms
2 additional potential revenue streams in Great Plains:
1) Restoring the deep-rooting, native prairie grasslands that absorb and store soil
carbon and stop soil erosion (hence generating a potential revenue stream from
selling CO2 mitigation credits in the emerging global carbon trading market);
2) Re-introducing free-
