2Non-Renewable vs. Renewable Use
- Today renewable energy resources provide 6 of
U.S. energy needs. - Fossil fuels meet 85 of U.S. energy needs and
80 of world needs.
3Reasons for Increase forRenewable Energy Uses
- New technologies are or will soon be economically
competitive with fossil fuels - The security risks for petroleum dependence is
growing - Environmental costs of petroleum fuels are
apparent - No single technology will solve our energy
problems - Combine renewable energy sources could gradually
transfer the U.S. energy system
4Renewable Energy Sources
- Solar
- Wind
- Geothermal
- Hyrdo
- Biomass
- Ocean-energy
5Encouraging RenewableEnergy Statistics
- North Dakota, Kansas and Texas has enough
harnessable wind energy to satisfy national
electricity needs - Some communities in northern Germany wind power
provides 75 of their electricity energy needs - Every year the earths surface receives solar
energy equivalent to 15,000 times the worlds
annual consumption
6National Energy Policyfor Renewable Energy
- Needs to be based on a sustainable and consistent
policy framework at local, state and national
levels - Must be based on sustainable development that
meets the needs of the present without
compromising the needs of future generations - Planning must include the value of ecosystem
services - All but 4 states now have incentives in place to
promote renewable energy - Governor Lynch has adopted the policy to obtain
25 of our energy needs from clean renewable
sources by the year 2025
7First Generation of Bio-Fuels
Top Five Ethanl Producers in 2005
- Ethanol 90 of total bio-fuel production
- Bio-Diesel 10 of total bio-fuel production
- U.S. and Brazil produce the greatest amounts of
ethanol - Germany produces the greatest amount of
bio-diesel - Ethanol is the U.S. is produced predominantly
from Corn - Ethanol from Brazil is produced from sugar cane
- Bio-diesel in Germany is produced from vegetable
oils
Top Five Bio-Diesel Producers in 2005
8Global Production 2000-2005
- Ethanol production doubled
- Bio-Diesel production nearly quadrupled
- World oil production only increased by 7
9Second Generation Biofuel Feedstock Cellulosic
Biomass
- Sources of Raw Materials
- Wood (i.e. Chips, sawdust, etc.)
- Tall Grasses
- Crop Residue (i.e. Corn Stocks)
- Organic Portions of Municipal Wastes (i.e. paper)
10Major Obstacles to DevelopingSecond Generation
Feedstock
- Fibers can only be converted into liquid fuels by
advanced technical processes, many of which are
still in development - Development is 10-15 years into the future
- Will require large investments by government and
industry
11On-Going Researchfor Biofuel Production
- To create fungi that are genetically modified to
produce powerful enzymes that are used as
catalyst to breakdown the complex carbohydrates
of wood into simple sugars - Reconfigure the DNA of brewers yeast which can
feed on the sugars in a fermentation process - Ethanol is produced as the sugars are consumed
12Benefits of Second GenerationBiofuels vs. First
Generation
- Large potential to substitute for petroleum fuels
- Can create energy security
- Has less interference with the food economy
- Requires less land and water resources
- Reduces the emission of both greenhouse gases and
pollution
13Benefits of Good Management Practices for
Production of Biofuels
- Could facilitate the sequestration of carbon in
the soil and vegetation - Provide a monetary incentive to protect and
restore ecosystems - Could encourage development of natural systems
with more complex ecosystems that increases
biodiversity - Such systems can protect watersheds, help to
restore degraded lands, and lands vulnerable to
erosion
14Worldwide Productionof Second Generation Biofuels
- Can bring in a broader group of countries into
the liquid fuel business - Diversify suppliers and reduce the risk of supply
disruption - Can be produced in every region of the world
- Could reduce poverty in the poorer regions of the
globe by enabling them to share in the production
and benefits of biofuel development
15Production Potential by Regions of the World
- Potential is greatest in tropical countries
- Tropical plants have a more favorable energy
ratio than those grown in temperate regions - They grown in more ideal conditions for utilizing
sunlight and water - Cultivated manually, with less fossil fuels
- Fewer use of fertilizers and pesticides
- Cheaper labor costs
- European countries have little land to devote
towards biofuel production - The U.S. is at a greater advantage than Europe,
but will still require imports to keep up with
demands
16Pitfalls to Avoid
- Potential to contribute to soil depletion,
erosion, habitat loss and reduction of
biodiversity - Potential to displace human populations in poorer
countries - Potential to further impoverish poorer countries
17Death and Decomposition of Trees
Death and decomposition of trees are essential to
maintaining the production of as healthy forest.
Any successful biomass management effort must
take nutrient cycling into account to succeed.
18SHIGOS LAW
IF THE RESEARCH GETS YOUR HANDS DIRTY, OR IF
THE WORK IS PHYSICALLY DIFFICULT, IT PROBABLY
WILL NOT, OR HAS NOT BEEN, DONE. THANK GOODNESS
THAT SOME RESEARCHERS ARE NOT AFRAID OF THIS
LAW!!!
19Dr. SHIGO
- Dr. Alex Shigo, plant pathologist for the US
Forest Service, who died on October 6, 2006, did
much to enhance the scientific knowledge of the
role of decomposing trees and nutrient cycling
within the forest.
