Multiple Benefits Local Picture

• Distributed generation - near the users
• Power quality - no surges, sags, transients
• Power reliability - back-up - augmentation
• Dedicated to uniquely high energy rates
• expressed in demand charges, peak
• power and ratchet rates
• Lower noise, emissions, waste streams

"All companies have a duty to provide
shareholders with more analysis and disclosure
on climate risks and their strategies for
managing or mitigating those risks," said Dr.
Julie Fox Gorte, vice president and chief social
investment strategist at Calvert.

IEA GLOBALSOLAR WATER HEATING

• 10 November 2004. The International Energy
  Agencys Solar Heating and Cooling Programme and
  major solar thermal trade associations publish
  new statistics on the use of solar thermal
  energy. The new data expressed for the first
  time in GWth, rather than in square meters of
  installed collector area shows the global
  installed capacity to be 70 GWth (70.000 MWth).
• "Now the solar thermal capacity should show up in
  all statistics alongside the capacities of other
  renewable energies", says ESTIF President Ole
  Pilgaard. "And seeing that the world wide
  capacity of solar thermal installations exceeds
  even that of wind power, people will realise that
  our technology can contribute tremendously to
  reducing greenhouse gas emissions and to making
  the global energy supply more sustainable."

Biomass - BioFuels

• Fort Collins, Colorado RenewableEnergyAccess.com
  2007-04-11 Researchers at Colorado State
  University and the U.S. Department of
  Agriculture, Agricultural Research Service have
  completed an analysis of greenhouse gas emissions
  from biofuel production. Study results revealed
  that when compared with the life cycle of
  gasoline and diesel, ethanol and biodiesel from
  corn and soybean rotations reduced greenhouse gas
  emission by nearly 40 percent, reed canarygrass
  by 85 percent, and switchgrass and hybrid poplar
  by 115 percent.
• Hybrid poplar and switchgrass were found to
  offset the largest amounts of fossil fuels and
  therefore reduced emissions the most out of the
  studied crops.
• Researchers were able to use life cycle analyses
  and the DAYCENT model to account for all of these
  factors as well as integrate climate, soil
  properties and land use to accurately evaluate
  the impact of bioenergy cropping systems on crop
  production, soil organic carbon and greenhouse
  gas fluxes. The study was published in the April
  2007 issue of Ecological Applications. For

PEW CLIMATE STUDY US 2006

• Pew Center Study Addresses Global Climate Change
• Washington, DC RenewableEnergyAccess.com
  2006-02-22 In a report from the Pew Center on
  Global Climate Change, a culmination of a
  two-year effort that articulates a pragmatic
  course of action across all areas of the economy,
  is the first comprehensive plan to reduce
  greenhouse gas emissions in the U.S.
• NOTE

The report concludes that there is no single
technology fix, no single policy instrument, and
no single sector that can solve this problem on
its own. Rather, a combination of technology
investment and market development
Among the many recommendations, in connection
with area of energy and electricity, is a call
"Incentives and a nationwide platform to track
and trade renewable energy credits are
recommended to support increased renewable
power."

Conclusions

• Energy efficiency can negate emissions growth
• Renewables can provide significant deep cuts in
  emissions
• The world is blessed with abundant renewable
  resources spread throughout the globe - with
  decentralized applications having the greatest
  near term
• impact and larger, centralized applications
  having longer term benefits
• Renewables can provide 1/2 of global energy
  remaining split about evenly among the renewable
  resources
• EE and RE can begin today to tackle global
  warming
• Continued RD and policy support will help these
  technologies achieve their large future
  potential, tied to aggressive tax and tariff
  policies
